VO2 Max: Training to Use Oxygen Efficiently

Originally published on HVMN.org (https://hvmn.com/blog/training/vo2-max-training-to-use-oxygen-efficiently) and authored by Nate Martins on January 3, 2019

VO2 max (V=volume, O2= oxygen) is the measurement of the maximum amount of oxygen utilized while exercising.

It may seem simple and inherent: you breathe in, you breathe out, you keep the workout going.

The importance of maximal oxygen consumption for exercise and the idea of the VO2 max was brought to into the fold by AV Hill, the 1920s by Nobel Prize winner from Cambridge. And it wasn’t even until the 1950s and 1960s that methodological studies were conducted to gather the accurate physiological elements required for VO2 max measurement of an individual.

Tools to measure VO2 max were created by Henry Taylor and his colleagues over the course of 12+ years at the University of Minnesota lab. Studies were conducted on military draftees who were conscientious objectors. These subjects were essentially at Taylor’s disposal; over a 12-month timeframe, they exercised for one hour a day, six days, and he collected data using methods that were groundbreaking at the time (but are still used today).

Now hundreds of labs all over the world can test conduct a VO2 max test. It used to be only elite athletes had access to these tests, but they’ve become a prevalent benchmark in endurance sport for those at all levels looking to improve their athletic performance.

Why consider testing VO2 max as part of your training? It’s possibly the barometer for aerobic fitness.1

Why Muscles Need Oxygen to Function

Muscles (and all cells) require energy production to function.

Energy inside cells comes in the form of ATP. Most of our ATP is created through the breakdown of metabolic substrates (food) using oxygen, resulting in CO2 and water. This means oxygen is really important, and as you exercise, energy requirements go up–so you need more oxygen.

Oxygen is absorbed into the blood by the lungs. It binds to a special protein called hemoglobin inside red blood cells. It then travels in the blood, and is pumped by the heart to the rest of the body, getting released in the tissues (including muscle) where it is used to breakdown our food to release energy.

The harder we exercise, the more we breathe and the more our heart pumps; this helps to deliver more oxygen. These are some of the critical factors that influence an individual's VO2 max.

However, muscles can make energy without oxygen in a process called anaerobic respiration. The only fuel that can be burned anaerobically is carbohydrate, being converted into a substance called pyurvate through glycolysis and then into lactate via anaerobic metabolism.

Build up of lactic acid happens when production occurs faster than our ability to clear it out. The blood becomes more acidic, which in turn can compromise muscle function.

Clearly, fuel source is an important factor relating to the amount of oxygen consumed. At higher intensities of exercise, muscles burn mainly carbs and at lower intensities, they burn more fat.2 Burning fat uses more oxygen than burning carbs, but we have more energy stored as fat, so you can keep going for longer when burning without running out of energy.

BHB, found in H.V.M.N. Ketone, is relatively oxygen efficient: when a working muscle burned both BHB and carbs it produced more power with the same amount of oxygen, increasing efficiency by 28%.3

Muscles are like an engine that need gas (oxygen and fuel) to function.

What’s Behind a VO2 Max Number?

The maximal rate at which an individual can process oxygen is usually expressed in milliliters of oxygen per minute per kilogram of bodyweight–this is the relative number most often considered a VO2 max.

An average, untrained male age 20-29 has a VO2 max of 35 - 40ml/kg; of the same age, the average, untrained female has a VO2 max of 27 - 30ml/kg.

You’d imagine endurance athletes, who need to make energy during long periods of aerobic exercise typically have the highest maximal oxygen uptake. Masters of endurance performance, like cyclists and runners, are usually near the top, with more explosive athletes, like weightlifters, near the bottom.4

Elite male runners can have a VO2 max values of 85ml/kg; elite female runners can have 77ml/kg. Miguel Indurain, who won the Tour de France five times, reported to have had a VO2 max of 88 at his prime, and Lance Armstrong had an 85.

But which athletes are at the peak of VO2 Mountain? That’s cross-country skiers.

Bjørn Dæhlie, a Norwegian cross-country skier, recorded a VO2 max of 96ml/kg. The result came out of season for Dæhlie, and his physiologist claimed he could have gone over 100ml/kg. He had the record for years but in 2012 was dethroned by another Norwegian, an 18 year-old cyclist named Oskar Svendsen, who reported logged a 97.5ml/kg. Remember, these scores don’t appear in peer-reviewed literature, so questions always arise about their accuracy.

How to Find Your VO2 Max

Do you know how many milliliters of oxygen per minute per kilogram of oxygen your body can consume at all-out effort? Probably not.

Training Centers

These supply the most accurate VO2 max testing. Professional labs (and sometimes training facilities) with exercise physiologists provide these tests, which are typically conducted by breathing into an oxygen mask while walking on a treadmill for a certain amount of time at a specific pace.

The only downside: it’s expensive.

During lab tests, a facemask is placed on subjects to measure the volume and gas concentrations of inhaled and exhaled air. Similar to lactate testing in a sports lab, athletes run on a treadmill (or sometimes use a stationary bike or rowing machine, depending on sport) and the exercise intensity increases every few minutes until exhaustion (read: you start having tunnel vision, hit the red stop button and collapse into a sweaty heap). The test is designed this way to achieve maximal exercise effort from the subject.

Usually, heart rate is measured through the test so you get data on your resting heart rate all the way up to maximal heart rate. Athletes will receive their ideal heart rate zones for warm-up, aerobic, anaerobic and uber-tough intervals.

The most valuable of this group might be the heart rate between aerobic and anaerobic exercise: the anaerobic threshold. Training will be geared toward improving this point, at which the body begins to accumulate lactate in the blood.

Similar tests can be replicated outside of labs with less accuracy.

Simple Heart Rate Test

Another way to roughly estimate VO2 max also makes use of heart rate measurement.

First, find your resting heart rate. Most fitness trackers can provide this number, but if you don’t have a fitness tracker, you can go old school. Find your pulse and set a timer for 60 seconds, counting the number of beats in a minute.

Then, find your maximum heart rate. This formula might oversimplify things, but it’s effective for the purposes of a loose VO2 max calculation. To find your max heart rate, subtract your age from 220. So, if you’re 30 years old, your maximum heart rate is 190 beats per minute (bpm).

Use this formula to find your simple VO2 max: 15 x (max heart rate / resting heart rate).

For example, if your maximum heart rate is 190 and resting heart rate is 80:

VO2 = 15 x (190/80)

VO2 = 15 x 2.4

VO2 = 36.6

This isn’t the most accurate formula, but it can provide a good starting point for training to improve VO2.

The Rockport Fitness Walking Test (RFWT)

This walking test can also calculate a VO2 max, and studies have proven its accuracy.

First, stretch and warm up. Then, find a track or mostly flat surface on which to walk a mile as fast as possible. It’s important to walk, and not to cross over into jogging territory. After walking exactly one mile, note exactly how long it took and your heart rate at the end of the mile. Using those numbers, you’ll be able to find an estimated VO2 max using this formula:

VO2 max = 132.853 - (0.0769 x W) - (0.3877 x A) + (6.315 x G) - (3.2649 x T) - (0.1565 x H)

W = weight (in pounds)

A = age

G = gender (1 for men, 0 for women)

T = time to complete the mile (in minutes)

H= heart rate

VO2 Max for Cyclists

Power is the golden egg of data for cyclists. It’s the gift that keeps on giving, as it provides some insight into finding a VO2 max, when combined with some field testing.

Pedal for 20 minutes at a maximum, yet sustainable, effort. Cyclists should monitor their power meters, maintaining consistent intensity while incrementally increasing wattage the first three minutes until finding a power output that can be maintained for the rest of the test. This should be a wattage similar to high-intensity rides or races. Use this formula to find your VO2 max:

VO2 max = [(10.8 x W) / K] + 7

W = average wattage

K = weight in kilograms

Improving Your VO2 Max

Two major factors contribute to a high VO2 max: the amount of oxygen you can transport and your muscle physiology.

Oxygen transportation includes a strong heart pumping blood through the body, with hemoglobin-dense blood, a high blood volume and high capillary density in the muscles. Better oxygen transport leads to higher VO2 max. Muscle physiology means how many muscle fibers you have, how big they are, how many mitochondria they are, and how strongly you can activate them during exercise. More aerobic, oxygen guzzling muscles equals a higher VO2 max.

Similar to lactate training, a training program can be implemented to improve VO2 max and help increase physical fitness, improving the way your body utilizes oxygen. Training is designed to have you spend as much time as possible at 95% - 100% of your current VO2 max as possible.

Limiting factors like gender, genetic makeup, and age all have an impact on an individual VO2 max–but training can always improve this number. Because lactate threshold and VO2 max are linked, check out our blog for additional ways to train with lactate in mind.

A note: since body weight is a factor in VO2 max, less body mass will inherently improve your score.5

Interval training often results in the most improvement of VO2 max.6

High-Intensity Training: Long Intervals


If you are good at pacing yourself, sessions made up of long (4 minutes or so) intervals at your hardest sustainable effort are a good way to increase VO2 max. Between each interval, you should keep moving; active recovery will keep VO2 elevated during the process. Plan to do 4-6 sets.

The 4x4 minute workout is a classic in all sports: running, cycling and rowing research has proven its efficacy.7 First, always remember to warm up properly for at least ten minutes. Then conduct four maximal 1,000 meter runs (or sprint four minutes) at 85% - 95% of your maximum effort with two to three minutes of recovery between each run. For cycling, find a section of road or a climb offering a challenging grade that you can work for 4 minutes. To mix it up you could try alternating between standing and seated efforts each minute

The idea is to save enough energy so that your last set is the hardest intensity. If you are running on a track or watching your power on the bike, ensure you’ll be able to go your hardest on the last set. Pace this right and you should be dreading the last interval. By holding a pace that’s at the upper limit of your ability, you overload your heart, lungs and muscles, forcing them to adapt to deliver and take up more oxygen.

In one research study, athletes who did a similar workout improved their VO2 maxes by 10%.7 Time to exhaustion, blood volume, vein and artery function all improved after the training period.

High-Intensity Training: Short Intervals

If you can't bring yourself to suffer four minutes of near-max intensity, you can go for shorter intervals–but they have to be an even higher intensity to provide a benefit. Short interval sprints of under one minute can also improve VO2 max as long as they’re conducted at almost maximal effort level.

The exercise test here is 8-10 sets of 1 minute sprints. Again, make sure you are properly warmed up–these workouts carry a risk of injury because of the amount of power produced. You have to give it your all during each interval without holding anything back.

From the same study mentioned above, those doing ten sets of one-minute high-intensity sprints on a treadmill at maximum rate (with a 1 minute rest in between each interval) increased VO2 max by 3%.7

Time to exhaustion, plasma volume and hemoglobin mass increased with this routine. However, results demonstrated that long interval training garnered the most dramatic results.

VO2 Max: Training Your Body to Use Oxygen

Being able to use a high volume of oxygen with a high degree of efficiency is one of the best indicators of endurance fitness there out there. Many factors contribute to this measurement, but what it comes down to is training–athletes must train to increase VO2 max.8

Some athletes are better equipped for high VO2 maxes. Runners, cyclists and rowers sit near the top of the totem pole, but cross-country skiers have typically reigned supreme. Regardless of your sport, a high VO2 can be a great gutcheck for your fitness level at a physiological level.

Because oxygen is so vital to our muscle function, we should be adept at using it efficiently.

Pillars of Performance: Optimizing Time, Correcting Underperformance, & Habit-Driven Training ft. Matt Dixon

Originally published on HVMN.org (https://hvmn.com/podcast/pillars-of-performance-ft-matt-dixon-episode-99) and authored by Zhill Olonan and Geoffrey Woo on January 8, 2019

Time. It’s our only limited & non-renewable resource.

If you’re an entrepreneur or engineer, it can be tough to set aside time for exercise when there’s always an email to respond to or a feature to write. If you’re an athlete, recovery can often fall by the wayside when your mind is fixed on seeing results.

We speak with Matt Dixon, founder of Purple Patch Fitness, a top endurance performance coaching company based in San Francisco. He is an expert in optimizing the lives of both time-starved athletes and knowledge workers. He was one of the first coaches to prioritize recovery and nutrition for elite athletes during a time when they were an afterthought.

In this episode, you'll discover:

  • The symptoms of underperformance

  • Which biohacks (for example, things like cryotherapy) are legit or overhyped

  • The difference in mindset between training and just working out

Geoff

Hey Matt, thanks for coming in the office.

Matt D.

Thanks so much for having me. It will be great to be here.

Geoff

There's a lot of ways we can slice into this conversation, given your background as an athlete, as a coach, as someone who's been in the performance space for a long time. To set a context perhaps, why not have you tell your story of how you got into performance, how you got into athletics.

Matt D.

Sure, and it might take an hour. I'll do the very quick and dirty. I'm obviously not from the states. I grew up on the east side of London. In the early '90s, a very lucky recipient of a swimming scholarship over here, so I came across after finding the Olympic trials in '92, not making the team. Came across, and had the chance to swim in university here, obviously the best swimming country in the world. I went through four years, and if you know anything about swimming, it's not an easy sport. Particularly at the time I was doing it, it was all about big volume, big work. The program that I was in was very much that.

Geoff

What strokes were you swimming?

Matt D.

I was one of the lunatics, I was a breaststroker in 400m. I did one of the tougher events. I spent a lot of time in the distance lane accumulating way too many hours, 27 hours a week of swimming was sort of our average. Then we had to do the strength as well, and go to university. But I didn't make the team in '96, and retired from swimming at the ripe old age of 22 or so. But my education at the same time was in exercise physiology. From there, I got into coaching swimming, and was very lucky to coach at a very good age group program. We had a lot of sort of top swimmers. I went through my first journey, everybody sort of continued the regular swimming mindset in many ways. But decided that with my sort of restless curiosity that I seemed to have, I decided to move on and go and get my Master's in clinical physiology down at the University of South Carolina. It was when I was down there that I got into, I found this book "Triathlon, Three Disciplines." I'm a big guy, I weigh almost 200 pounds, so I also had a big engine. I run like a donkey dipped in cement, but I gave myself a shot at it, and I ended up doing very well.

Really from there, I sort of now had this backbone of elite swimming, coaching experience, and a background and a Master's of clinical physiology. I decided to go and try my hand at professional triathlon. I think the reason I give you that background is I'm a wonderful example of how to do a professional triathlon career very, very poorly. With the help of some terrible coaching, over sort of three or four years managed to train myself into the ground. I think it's indicative of what the sport was at the time. Success was just more, more, more, how many hours could you accumulate. Everything like recovery lip service, and recovery strength and nutrition was just lip service.

Geoff

Right.

Matt D.

For me, that was really the fundamentally best thing that could ever happen to me, when I look back now as a coach, because that forced me to reflect and was really the start of my coaching journey in triathlon and performance globally. I just thought, there just be a better way.

Geoff

I think that's been a recurring theme over the last, a lot of the conversations that we've had on the podcast and industry on the field. When do you think that tipping point came where there was that mind shift from, let's put in volume, you're a champion, tough it out, why are you being a softie? Towards, hey, you know, recovery is an active process. Let's be thoughtful about it, let's actually bake it into the routine. It seems that the conversation over the last maybe couple, two or three years have really accelerated. Or is that just a perception change, and it's really been a conversation over the last 10 years?

Matt D.

I'll say I think it started 10 years in a way. I remember when I first started Purple Patch, which we're 11 years in now. One of my first, what's always been important for us is education. I decided that I was really going to be polarizing not for polarizing's sake, but the traffic was going in one direction. As you say, the direction of just toughness. Out of my own experience, I thought, I've got to go about things in a different way. Because I fundamentally believe when I look back that there is a better way, a smarter more pragmatic approach, both at the world class level and at the amateur level. Right at that time, we started with a methodology where we didn't just look at endurance training. We sort of viewed the program as being what we call now for an education sake, the four pillars of performance. We talk about endurance, we talk about nutrition and everything that falls under that bucket. Strength and conditioning, which I think is critical for endurance athletes, and that topic of recovery. I decided to really start to write about recovery as that subject to that point. To answer your question very briefly, when I started talking about recovery, it was really polarizing. I somehow became known as this recovery coach. Some people, it really resonated with, and some people it was not exactly kind when they referred me to that.

I wasn't alone, I wasn't this maverick or pioneer of recovery. But I did see that right at the point 10, 15 years ago, that the sea was changing. It resonated, the message, because we had so many athletes, particularly busy time starved athletes, that were under-performing, both in terms of their effort they were putting into their sport, and their performance return that they would get from it, but also in life. They were walking around fit and fatigued. So it was almost like this message that was like, "Ah, that's what I want." I think that the sport started to evolve at that time across multiple levels. The acceptance that strength and conditioning is a key component, the understanding that nutrition and hydration is a part of the performance puzzle, not just an afterthought. And recovery not being a sign of weakness, but actually being a part of the program to facilitate what is still a tough sport or a tough set of sports. Endurance sports are challenging, but it's really the performance catalyst in many ways.

Geoff

Yeah. What did that initial insight come from? Was it a specific publication coming out of the research literature? Was it just your personal experience, and you coaching people and realizing, hey, if they take a couple days off here and there and do some active recovery, people are actually seeing better? So is this more of a practitioner lens that you've had these insights 10, 11 years ago? Or did it come from some seminal papers that you looked at, you read in the literature?

Matt D.

I did my Master's degree in clinical physiology in the late '90s. I don't even refer to myself as an exercise physiologist anymore, because that is such a young exploding science. I think it was at that time though it was a great backbone of knowledge, and I was reading plenty. I was reading lots of research, but I didn't get the answer or the catalyst of a methodology off of a research paper. I really got it out of an accumulation of my own experiences, and my own experiences being my own personal journey where I was world class in terms of work ethic. I was a performance level down. I was never going to be a world champion. But the one thing I could do was work really hard. I was unfortunate in some ways that my structural body, my muscular skeletal system was robust, so I could drive myself into the ground from a hormonal level, let's call it that. It was that experience, coupled with looking at the performance returns of other athletes that I swam with, other professional triathletes that I viewed and knew, and then my first exploration into coaching. I just looked at it and thought, this just doesn't make sense. So I think it was an accumulation of all of that. And I think one thing that can't be understated is, when you have sort of done it to yourself, but when everything is removed, so you lose all your sponsors, you lose the ability to exercise, I couldn't even, let alone training, I wasn't even exercising for a couple of years.

Geoff

So you really crashed.

Matt D.

It really crashed. When that happens, it forces you to look back and think, okay, let's actually take a real look at the landscape here. I realized I wasn't alone. It wasn't that everyone was in my situation, but I did see too many people in a fog of fatigue.

Geoff

Were there specific biomarkers that you looked at? Was testosterone down? Was cortisol up?

Matt D.

I think I had the testosterone of, I had my choice, either an 85 year old man or a four year old child. I went with the 85 year old man. I had very, very low testosterone, very limited cortisol response. You can imagine my iron levels were in the toilet. Everything across everything. Actually, I think that at the time as well, you're desperate to seek answers. I went to all kinds of doctors. This is past now, a professional triathlon is behind me. I went to all kind of doctors to try and get an answer. But ultimately, the answer was time, rest, healthy eating, and a very pragmatic lens on exercise. Even though I was an athlete that loved to train, I couldn't do that. I had to actually be smarter. But it wasn't something that could be rushed back by some magic supplement.

Geoff

It sounds like you were just stressed almost in a battlefield like condition.

Matt D.

Yeah.

Geoff

We talk to a lot of folks that serve in the military, and folks that have accumulated so much damage and time in the field have similar symptoms, like low T, high cortisol, maybe some sleep issues.

Matt D.

Yep.

Geoff

It's hard to reverse. It's not just like some acute damage, you break a bone, you can heal. It's just like an accumulation of a lot of stress. It sounds like you were very much working your body down and pushing it at such a limit.

Matt D.

And when it goes, it's very hard to define exactly. What is the symptom there? But I think up a level from that as well is the people, and so many of them at that time, that I felt the people that weren't in that stage, it's not that everyone was walking around in a coffin type thing. But it's the people that were just not getting the results relative to their hard work. Their only sort of route that they knew to try and seek more results was to do more work. And of course that becomes-

Geoff

So you're in a negative death spiral.

Matt D.

It's this negative death spiral. You saw so much. At that time in the sort of early years of Purple Patch and my coaching, I was very lucky to actually start to work with a few athletes that almost became my living laboratory. It was accidental, but it was very fortunate. I had a couple of my early professional athletes that happened to be working with real jobs at their time. So I was forced to try and get them to world class within the context of a very busy life, rather than a regular professional athlete that only focuses unapologetic world class performance.

Geoff

On 24/7 to train and rest.

Matt D.

Exactly. So how do we get these athletes to compete against those other athletes with all the time in the world? I had that challenge. Then I had one particular athlete who is very well known in the triathlon space, Chris Lieto, who was already world class. He had been on a journey, he had already won multiple IRONMANs and multiple Half IRONMAN races. His big quest was the Hawaii IRONMAN. This is going back to 2008, I think, when I started working with Chris. I looked at him, and looked at the landscape of him. While he was an infinitely better athlete than I was every going to be, I saw symptoms of under-performance relative to the work he was putting in. He was working out or training 30 hours a week. When I looked at him, there was no strength, recovery was an afterthought. I felt like he was under-fueled relative to the training.

Geoff

To his exertion, yeah.

Matt D.

All credit to Chris, he had been down this journey for many years. For his last two to three years, all he wanted to do was to perform great at the Hawaii IRONMAN, which is the world championship, and the toughest IRONMAN there is, Kona.

Geoff

The Kona, yeah.

Matt D.

He took a massive risk with me. I was pretty much a no name coach. I asked him to do a few things, which was the first to cut his total training volume by a third, to really take recovery seriously both in terms of sleep, which has become a trendy topic nowadays. But really maximizing sleep environment and the hours of sleep to try and improve the quality. He was eating around 1,500 calories a day more than he was in his previous years, and we started doing some strength and conditioning. He was moving into his late 30's, and I felt like there had to be a different way. That year was really a magical year, his first year, because Chris had always been upturned by muscular skeletal injury. That year, we managed to create the magic word in performance, consistency. He showed up to Hawaii that year, and he was already talking about next year. I could tell that he was as fit as he needed to be, and he had a big platform of base. But he was excited, and that really told me he was fresh. He missed winning by two minutes, but he got second at the Hawaii IRONMAN, a huge breakthrough performance. That was a wonderful opportunity for me and athletes like him to start testing and proving.

Geoff

Yeah, so it sounds like a lot of your intuition here is qualitative in assessing the athlete. I know within the last probably three, five years, it is much more quantitative biomarker trackers. This is a heart rate variability ring, so it's not just a piece of jewelry.

Matt D.

Yeah.

Geoff

Is that something that you look at now as these technologies are evolving, or is it a combination of you as a feel, the human side of engaging with your athletes seeing input output not matching? Or are you starting to use some of these quantitative tools?

Matt D.

It's the marriage of the two that creates the optimal scenario. One of the challenges for performance driven people globally is that there is a natural inclination to become what I call paralysis of analysis, getting driven by the information and the metrics. The truth is that the information that we receive, whether it's heart rate variability, sleep tracking, power meters on bicycles, biomarkers information, for me it is valuable information if it is actionable and it starts a conversation. But the human body, we're not building a bridge, we're building a human. It's highly variable, and ultimately has to withstand all sources of stress. We really try and sort of empower the athlete to be a thinker, and we use the information. We do use a lot of that information, we like to track sleep, we like to track mood, and obviously that's qualitative and quantitative. We capture data on all sessions that the athlete's doing, and we use that as information to help us paint the picture of which then it's a human decision that has to occur from that. A part of my job as a coach, or our team's job as a coach, is to help educate the athlete and then empower the athlete to ultimately become self-sustaining, to actually be able to make smart decisions. I think it's the same thing with the emerging trend that's happening now, that will happen in the coming future, is AI and machine learning, which is really interesting. If you take data science and you look at best decisions, but all of the companies that are going to come on the scene for that have to realize I believe that I don't think that will ever be a replacement for the human intuition and gut that has to become along as a part of the equation.

Geoff

Yeah, and I think that's been consistent with a lot of my conversations with coaches and athletes, in the sense that, I could I just get your thoughts here, sometimes coaches will analyze the information but not expose the raw data to the athlete. You don't want to confuse them with, you had a low heart rate variability rating today. I don't want to prime you that you're not going to have as good of a session today.

Matt D.

Yeah.

Geoff

Do you play with that, or are you pretty transparent, like, "Hey, here's the raw information. Let's not over-interpret the data here." How do you balance the priming the athlete for a really good day or bad day with like a placebo and nocebo effect, versus how do you actually be quantitative here?

Matt D.

I fall onto the latter more, sharing. But before then, I think there has to be a discussion and an educational process around how we are using the data. Even from a prescription standpoint, I'll come back to the question, but from a prescription, athletes tend to be very metric driven when it comes to what intensity should I ride my bike at, for example, or what should I run at. Even when there are prescription, we have a range of let's say power on the bike or pace on the run that we expect an athlete to be. But we prescribe it in terms of what this should feel like. What's the intention of the workout, what's the intention of the intervals within the workout, and what should that feel like? That could be in terms of perceived effort and the sensations that the athletes feel. Then on the other side of it is the marriage of, well these are the outputs that we expect, somewhere in this range. But that's a very different mindset than, "Here you go, Johnny, ride at this power." Because that's theoretically specificity, but that ignores what the body is providing us for that day. To answer your question, when it comes to some of the data that you might be looking at, it's data to help us make a decision or to frame where it is. So this is where we're at, let's see what the body can give us.

Matt D.

This is basically the decision making tree that the athlete can say, "I want to be open to a good performance, but if I was a little suppressed this morning and I get a good performance, then it really might be time for an extra day or two off that's a little bit lighter." Or, "Okay, this is the data, and my system's a little suppressed." Then they don't feel guilty if they give it a shot, go through a warmup, go through a pre main set, and it's just not there. There is reality. So I tend to prefer to share, but share within context. Ultimately, I'm dealing with highly motivated adults. I think that truth and education empowerment, and trusting that you can bring the athlete to look at things through your lens is long-term the more effective way to go about it.

Geoff

I think one assumes that, okay, if we're rational adults here trying to be the best possible version of ourselves, then more ground truth is better. It's interesting. In terms of you assessing how recovered someone is, or manipulating your protocol for them, do you take perceived exertion as the highest order a bit, or do you see some of these quantitative biomarkers, like HRV or amount of sleep. Or is that kind of a dumb question, like you still take both?

Matt D.

Both, but I think that the golden question is for the coach to ask the athlete, and for the athlete to ask themselves is, how am I feeling? One of the things that doesn't happen in busy lives is a pause. When you first wake up in the morning, you can't overstate the value of actually coming out of the weeds a little bit. Any time that you can have a conversation with yourself or a conversation with the athlete to say, come out and that you say, "Hang on, how am I feeling here? What am I looking to do," is really positive. Ultimately, that's the decision. Then what you have is the other supporting information to help make that decision. I'm not so sure, and there's the data, okay, that's clear. It's objective. But what I wouldn't do is say, "Oh, look at that HRV, for example, we shouldn't train today, period. I think that's just being shackled by the information.

Geoff

Yeah. I think when people think, okay, recovery, that seems intellectually appropriate, but what do I even do? When you tell your athletes to recover, is it like, hey, go sit down and watch Netflix? Is that, do some stretching? Is that, do some yoga? When you're actually recommending, prescribing recovery, what is the most optimal way to recover?

Matt D.

I'm a big fan of trying to boil complex to simple, so I make this as simple as I can when I talk about this. But I see recovery having really three main buckets. The first is sport specific. The second big area is lifestyle in many ways. And the third is what I call modalities. We'll just go through all three very quickly. Sport specific is planned recovery within the sport. For some people, for emotional reasons that means doing nothing from a training standpoint. Sometimes people just need that break, they need to release it from the calendar and not move their body. But typically, it tends to be, I'm more of a fan of active recovery. Very low stuff, maybe with a little bit of neurological stimulation, a little bit of very, very short fast stuff just to keep the dialogue between brain and muscle going.

Geoff

Just like slamming like a medicine ball or something?

Matt D.

Yeah, something very short, or a very quick pickup if they're running, and going up to a very fast speed type stuff. But nothing where they're looking to get fit or stronger or more powerful. Actually facilitate the bridge between hard work. And then of course within sport specific, you have things like how you're managing a season, how you're managing a block of work, where you have programmed multiple easy days in a row, or complete season breaks. But there's a whole category of that, and globally the need to know for the show is keep moving, but keep moving light, and nothing that's accumulating fatigue. The second area then is what I would call lifestyle. That is obviously around sleep, nutrition, fueling, which is a critical habit driven component in my mind of consuming calories after workouts, particularly for heavily training athletes. It's not just about restoring the calories that you've done in the workout. It's about sustaining energy, stunting cortisol, the stress response post-workout with protein.

Geoff

Yeah, rebuilding muscle protein.

Matt D.

And then rebuilding muscle protein.

Geoff

Rebuilding lycogene, yeah.

Matt D.

And obviously, preparing for upcoming sessions. A good platform of eating is obviously a part of recovery, as is post-workout fueling, as is daily hydration. In every training session you are doing, you are finishing suitably dehydrated, you'll never retain full hydration status. So what are you doing to facilitate recovery? Then the final big component is modalities. I might say that's everything that you have to pay for. Whether it's foam rollers, or body work, or stem machines, or compression socks, et cetera. They're all great, they're all nice, but they're just the little sprinkles on top of the cake. If you fundamentally don't get the program right, and you fundamentally don't have very simple but actionable supporting habits, the modalities are useless. That is way down on the priority list for me. Unfortunately, in performance driven people, the important stuff is less sexy. This stuff is more sexy, it's gadgets and you can pay for it. That becomes everyone's focus. Ultimately, if they have a smart and appropriate training program that integrates into their busy life, and it's supported with some very simple habits, they're going to be able to recover better and ultimately perform better. The other stuff, nice to have if you've got time and money.

Geoff

Just to be more pointed here, what do you think is in terms of modalities most overrated, most bullshitty, versus what you think is one of the best modalities?

Matt D.

I'm generally not a massive fan of cold water immersion.

Geoff

Cryotherapy story.

Matt D.

Cryotherapy stuff is mildly interesting, but not that interesting to me. I actually prefer heat. That's less of a physiologist's lens, and more of a coach's lens. I don't like interrupting the post-training adaptation process too much. I think we're at this point where there's this really interesting collision of research.

Geoff

Yes, so something that I've been looking into as well, I'd love to dive into this, the cold versus hot.

Matt D.

Cold versus hot. We're at this point where I think that any sensible coach would say, "I don't know right now." I think it's different tools for different jobs. If there's an isolated area where it tends to be that, yeah, an isolated area that's maybe a specific injury, then very cold treatment might be helpful. But for a heavily training athlete, consistently I see that when they come out of the cold immersion, whether it's ice bath or cryotherapy, it tends to make them feel less good when they go into their next heavy session. Versus heat, there's a great opportunity that if you're sitting in a steam room or you're sitting in a hot tub and you're able to do some mobility type stuff in there without looking too pornographic, it tends to make people feel good. It's relaxing, it's enjoyable. When they come out of it and they come back into their heavy training, joints are mobile or joints are loose. I'm working with heavily training sort of endurance athletes, but that tends to be the trend that I see. So I slide towards that.

Geoff

Interesting. I think from the physiology perspective, I think you touched upon a topic that I've been looking at, which is that for cold therapy, you halt, you insult the post-exercise adaptation.

Matt D.

Exactly.

Geoff

Where in a steam room or in heat, you actually sustain and accentuate that stress response. Some of the data coming out with hot saunas and steam rooms, you actually elevate growth hormone, you accelerate the heat shock protein recovery process.

Matt D.

Yep.

Geoff

Whereas, with the cold ice baths, you halt that insult, and then you halt the adaptation period, which might reduce inflammation. So you might not be as sore potentially, but you're not getting the benefits of being exercised.

Matt D.

But why are you training?

Geoff

Right, exactly. You want to get the effect of your exercise.

Matt D.

If the training is smart, and then you go, and the other thing that heat does as well for an endurance athlete is, by doing post-workout heat immersion, it actually helps with some of the physiological stimulation to perform in a hot environment. It also boosts your blood volume. So if you under-hydrate immediately following and put yourself in a little bit of a stressful situation from that standpoint, and then immerse yourself in heat, you're going to get heat adaptation, which is a nice positive. Then of course you hydrate over the rest of the day.

Geoff

Yeah. So I think that's spot on. I think that's a very nuanced argument. I think that's at the really cutting edge, and I think right now people are, "Oh, ice bath and then sauna." I think it's very confused.

Matt D.

Yeah, it is.

Geoff

I think people out there, the general lay, even coaches, I think they're just confused about that, if you talk to professional coaches. I'm glad that we're touching upon something I think at the cutting edge that will be more fully understood. But I think to be perhaps fair or steel man the cold argument, I think there's probably some application for, okay, you have an injury, you have another basketball game or a soccer match the next immediate day. Maybe you don't want to do the adaption training now. You want to just get your body in the place where you can go again tomorrow. Then I can see it's a compelling story. Does that seem fair?

Matt D.

A hundred percent. I was going to say, it's a sort of performance readiness tool. So I can imagine a MBA player on the road, and they've got to play, and come back tomorrow. We're not looking for adaptations there, or we, I have nothing to do with the MBA. But we're not looking for adaptations there. We're looking to be able to perform the next day on the court. That makes perfect sense. I'm not saying, hey, cryotherapy chamber, it's useless. It's not, it's really interesting stuff. But for people that are just looking to train and create optimal adaptations and carry it throughout the rest of the day with proper energy, it becomes more interesting with heat.

Geoff

Yeah, I think I'm on the same page there, where if I'm not trying to compete in a specific event, then I'm always using heat. I'm not really trying to blunt my adaptation.

Matt D.

Yeah.

Geoff

What are some good modalities? I guess we like heat, cold we're a little bit more skeptical, or we need to apply them in the right indication in the use case. Foam rolling, stretching-

Matt D.

Foam rolling and body work.

Geoff

What do you think of that? You think, what the fascia tissue, is that something that you think is beneficial, or is that just like a nice massage and it feels good? Maybe that's a benefit of itself.

Matt D.

I think so much of it comes down to the practitioner, and understanding. But time and again, the body work if done really, really well, is a great supplement. Going to a nice massage and having the legs flushed, it feels nice, so it might be good for the soul. But I don't think it's actually really being beneficial. The one thing I will say, our general approach for body work is to try and align the body work on a day of heavier training, because there's so much trauma happening. On the days that we are actually really looking for recovery, we like to leave the body alone. What happens with all sorts of body work is there is a little bit of trauma that occurs.

Geoff

People are really digging into the tissue, yeah.

Matt D.

Yeah, they're really digging in. So we don't want to do that on a day that we're looking for recovery. We want to have the body work done at the end of a hard training day. Then the next day, let the body regress to the mean. The body is wonderful at regressing to the mean, and that's what we want it to do. So let it have a time of healing. That really relates to injuries as well. Hot spots that people have, little niggles and pains, and they get foam rollers or trigger point. They just go hammer and tongs at it. They isolate the spot, which is typically the symptom not the cause. My IT band hurts, so I'm just going to absolutely hammer it. They end up doing so much trauma that the body can't respond.

Geoff

It just tightens up, yeah.

Matt D.

It just tightens up. They end up actually magnifying the injury. So I think that whole area is good, but it's really dependent on the practitioner. Some of the foam roller stuff is great. On stretching, I'm not a globally massive fan of static stretching. The old school classic hamstring stretch, or put your leg up on the table and just holding it in position. Stand and lean against the wall and lengthening the calf, and just leaving it there. We do a lot of work on what we call dynamic stretching, a lot of mobility work. Even post-workout, particular to me as sort of focusing generally more on endurance sports, most of the work that we're doing, we're not putting the athletes into massive acidosis. Even components like a cool down is in a time staff life. Warmup is critical, cool down less critical. We don't spend a long time cooling down. We don't do static stretching afterwards. We tend to do more range of motion and mobility exercises.

Geoff

Interesting. Yeah, I think that's something that I've personally just found much more interesting and it seemed a lot more effective. Doing more dynamic movement and stretches, rather than just trying to touch my toes.

Matt D.

Trying to touch your toes. It's funny, because I remember a couple of years ago watching the professional soccer players in the premiership, and they're all out on the field doing static stretching. But there's really interesting research around static stretching-

Geoff

Before games.

Matt D.

Before games leading to under-performance in sprinters. And there they all are, some of the best soccer players in the world, doing static stretching.

Geoff

You've got to tell their physiologist, hey-

Matt D.

Tell their physiologist, you've got to catch up. I think they are, but certainly for our athletes we don't do any static stretching before, unless there's some form of medical reason, so under the guidance of a specialist.

Geoff

How about more speculative modalities? Have you heard of infrared saunas? Is that on the edge of your knowledge? What else are some of the crazier modalities that you've seen?

Matt D.

We're building a center in San Francisco, and I think we're going to put an infrared sauna in there. I find it really interesting.

Geoff

Okay, you think it's reasonable, okay.

Matt D.

I think it's reasonable, but I haven't made the purchase yet.

Geoff

As you point out. Let's more on to nutrition. I think that's interesting coverage on the modality side. Obviously with our audience, a lot of interest around fasting, ketone diet, low carb diet. We had on a number of carnivores on the podcast recently, which were interesting conversations. We had on Mikhaila Peterson, who is the daughter of Jordan Peterson, who is a famous Canadian psychologist. We had some of the moderators and thought leaders in the carnivore space, I think a lot of interest in diet. I think it's always something that everyone cares about, because that's what we kind of make decisions on every single day. I would say that in the endurance space, there's perhaps an upswing in interest in low carb, but I think that needs to be thought of in a very careful way. Obviously, when we're doing IRONMAN triathlons, these are very intensive, so you want to be fueling properly.

Matt D.

Exactly.

Geoff

Just doing a fasted marathon is probably not the smartest thing to do if you want to actually win. What are your thoughts on diet and nutrition? Maybe you can unpack some of the considerations here.

Matt D.

The first thing that I would say is I'm not a massive fan of evangelism across any subject. As a coach, I try and surround myself with smart people, and I remain curious and explore. You guys, it became maybe a great case in point, where it's this really interesting exciting research that needs to be reviewed and looked at. But I don't think any of us can say, "Oh, we have the answer to nutrition globally." I tend to start at a place of habit driven. What are the key components. I don't think that you can have a discussion around nutrition without being in context of what the person or the athlete is trying to do.

Geoff

A hundred percent.

Matt D.

If you take a type 2 diabetic that is relatively inactive and has been living on a diet of processed food and sugar. That is a very different methodology that you might use of intervention to try and help them thrive and repeal their type 2 diabetes, than a fit healthy IRONMAN amateur triathlete that's trying to perform at their best level in IRONMAN. When we sort of mix the two and say, "This is the solution for all," I think there's going to be a collapse somewhere. From a performance driven population, I start with things that I think are, what are we looking to achieve? If we're looking to train consistently, achieve adaptations, and thrive in the other compartments of our life. So our work performance with cognitive function, et cetera, our health, and bring the best version out that we can for our family. For most performance driven people, that's what we're looking to achieve. For someone that's training or exercising in the morning, for me that means that we tend to front-load carbohydrates, and we tend to have carbohydrates following the workout when the gateways are there. But not carbohydrates alone, it has to be supported with plenty of protein and some fat. If they do that well, so I'm not a massive fan of fasting post-workout. I guess that's the message out of that.

But if they do that well, the last thing that someone that's sitting in the workplace wants to be doing is consuming a whole bunch of starchy carbohydrate and a whole bunch of sugar. That's going to start to create fatigue. Instead, we tend to anchor around lots of proteins, lots of vegetables, lots of fruits actually, and just a general well-rounded diet. To answer your question, maybe you just sort of probed me more into specific areas.

Geoff

Yeah, I think I just opened a giant can of worms here. I want to-

Matt D.

Yeah, exactly. I tend to be more habit driven than anything else. But if we think about our professional athletes that we work with, our very elite athletes, we have several of our athletes that are what we might call fat adaptive, if you want to think about that. None of them are fasting, eliminate carbohydrates from their life. They embrace fat utilization, they embrace proteins, they have to eat a lot to support their training. Actually racing, the predominant fuel source still needs to come from carbohydrates.

Geoff

Right, so I think that because we talk a lot about ketone esters, fasting, ketogenic diets, people think that we advocate that, or I advocate it, or I am on a ketogenic diet every single day of my life. I'm not. I think that you touch upon it nicely where you have to look at the indication to optimize your nutrition and your protocols around that. So again, I think you're absolutely on the dot. If you're a type 2 diabetic, you probably want to reduce as much carbohydrate intake as possible.

Matt D.

Yeah.

Geoff

But if you're trying to be at the highest level of performance, clearly there's a role for sugar for the anerobic push at the end of a race or during a race.

Matt D.

Yep.

Geoff

I wanted to touch upon what you mentioned, which is keto adaptation or fat adaptation. I think one interesting active debate in sports nutrition is, can one be as keto adapted as possible and have as peak performance as someone that's being filled with carbohydrate? I think some of the work out of Volek and Phinney are advocating, okay, keto adapt for six, nine months, and you don't need carbohydrate. I'm personally a little bit skeptical about that, given just some subjective in practice experience, and just looking at the broader literature of how useful a punch of sugar can be for performance. That sounds like a lot even for your keto adapted athletes, you still recommend carbohydrate during the races or before the races.

Matt D.

Let's think about the other side, I think, for the equation. When I hear stuff like that, the chances of that being function across and long-term, it would be like suddenly finding out that gravity exists. It's too revolutionary for me. Not to be too dismissive, I think it's really interesting. I think about it like this, and I'll talk in terms of triathlon globally or endurance training. If you're going out on a low intensity long endurance bike ride or run, you don't need to be packing your gills with Gatorade and sugar, and everything that was pushed and marketed and promoted to us for the last 25 years. That's a mistake. You can eat, in my mind and just my opinion, but you can eat real food that is not carbohydrate heavy, because you can train your body to actually become more fat adaptive, if you want to call it that. You shouldn't be overly dependent on high sugar in those environments. But if you're doing a very short, very high intensity interval workout, then on the flip side there is a case to be told that sugar is your friend in that environment. If you are doing an Olympic distance triathlon that is two hours of very high intensity, or running a marathon at the elite level-

Geoff

You're going aerobic-

Matt D.

You're going aerobic, and there may be, and it's really interesting, of is supplemental exogenous ketones, it's really interesting to me. But I don't know enough about it yet. So rather than just for me jumping on and saying, this is great, it's the next big thing. Let's stand back, explore, investigate, research, and hopefully lean on guys like you to-

Geoff

Have you experimented with ketones?

Matt D.

No, not at all.

Geoff

We've got to get you to experiment a little bit.

Matt D.

Yeah, will do. But the case comes back, it's pragmatism. I think it's where I started with evangelism, where there's this, in the same way as what do we learn from history when we were told that fat was bad? We saw what happened there. On the flip side-

Geoff

Right, you brought up-

Matt D.

Yeah, if it's this polarized, carbohydrate is bad, there has still been no diet that I'm aware of in history where a complete elimination of one of the three macro nutrients has ever been successful long-term. I still haven't seen one that's been successful.

Geoff

Yeah, well I think that's the N=1 that all the carnivores are testing out live right now.

Matt D.

Yes, exactly. Well, let them be the living experiment.

Geoff

We'll see, exactly.

Matt D.

We'll see, and it's investigating. I'm not being by any stretch dismissive of it. I think it's very interesting. But I also don't claim to be an expert. It's a part of my field, that I'm on to explore and understand and talk to specialists about to build than a pragmatic-

Geoff

Yeah, I just want to get your thoughts there. I think one thing that we've seen getting more and more traction is this notion of cyclical diets. We touched upon the notion of keto adaptation or fat adaptation, or fasted workouts. The notion there is that you want to stress the metabolism, so you up regulate enzymes and proteins that relate to when you're at later stages of the race where you are more fuel depleted. Then you also do training when you're fully fueled to give your body full adaptation across all types of fuels. Is that something that you guys play around with, or do you stay pretty consistent? That seems to be one of the things that you folks, on consistency we have a fairly stable diet, and we just put people on their habit and let them go.

Matt D.

There's a reason for that, where if we think about in terms of things that are mutually exclusive. If you only think about it at the enzyme level, you say, this happens in the lab, and this will happen, so this is what we should play with. I tend to come up a level and try and look at the whole landscape. For the vast majority of people that we're working with, if we remove the world class athletes that have all the time in the world to plan their meals, to sleep, to take naps, which is a huge part of recovery by the way. Everything that we would love in an optimal situation, there's more opportunity to play test and align. But most people are trying to integrate performance health fitness into a really big life. What's the knock on effect of someone if they fast, they get up, they go and train, they don't replenish calories afterwards, and they go into their work day.

Geoff

And they feel terrible.

Matt D.

They're going to feel terrible all day, so their cognitive function will lower, their decision making will lower, their ability to focus will drop. And ultimately, they're going to have massive motivational urges for foods that they don't want to eat.

Geoff

Right.

Matt D.

They have them in the afternoon, and they end up buckling because it's human nature. It's a part of their life, it isn't their life. So they end up eating pizza or ice cream, whatever it might be, and then they crash in the afternoon. It becomes incredibly stressful. When we are training within the context of a time starved life, we are placing a specific stress into a whole big reservoir of stress. The challenge of getting enough sleep, travel stress for work, your commitments at work and obviously with your family. It comes back again, it's really interesting, but the solution has to be habit driven and repeatable. Similar to the mindset of modalities, in order for anything to be effective, it has to be simple to execute and repeatable. They might go through phases or opportunities where you can look at the workout, look at the day and say, this is a time that maybe you're doing some careful reduction of calories or fasting. But it has to be done very strategically within context of the big picture. I think that's where people miss it, because in thinking that they're doing the right thing in one particular area, they fail to see the big picture.

Geoff

Right. I think it's an important caveat. I think one thing that is kind of my pet hypothesis here is that cyclical training blocks is fairly standard practice now in top level sports physiology training. Right?

Matt D.

Yeah.

Geoff

Like you'll ramp up a load, and then taper down before the event. I can imagine a world where, again, the caveat is that this is a professional with an infinite amount of time and resources to have custom diets. You have cyclical nutrition blocks that match your training volume that also peak for the competition. That could be an interesting interplay where the training volume is now sort of cyclical and customized, can you imagine that one of the other interventions, nutrition, is also cyclical and personalized for an outcome? It's funny you say it, because I was listening to that question. I think in some ways I'm a dummy. We kind of do that in a way, and I'll explain. You're dead right, and let me preface this first. It doesn't just have to be an athlete that needs to train. I think everyone needs to train, because exercise is random, training is structured and progressive. So even if you want to be the healthiest human being possible, I think most people that exercise want to improve.

Matt D.

The only way to do that is to have some structure and progression. From an athletic sense, that means that we're sending athletes through phases of training. The phase of training that we tend to be in right now is what we call post-season, which is the lowest physical stress. It's really a phase of preparation, so we're doing a lot of technical development and a lot of readiness of in the upcoming months being able to absorb and handle very heavy training loads. So at this time of the year, we really encourage athletes, this is a time of the year that there shouldn't be a workout where you are consuming high sugar, because the training load is not there. Versus if we go into right in the heart of race season and we're doing race simulations, we want the athlete to be adhering to the same timing amount and type of calories that they're going to be absorbing in the race specific training sessions. Not every training session, but in the ones that most mimic what they're going to do on race day. In many ways, it sort of is periodized, if you want to call it that. It is phase specific. So I said, hey, it has to be simple and actionable. We still do go to that level I would say.

Geoff

Yeah. I think the marketing side is interesting where, it makes sense again I think where you're speaking of like Gatorade, GU shots, it makes sense when you're in practice. But if you're a casual athlete who maybe goes to the gym for like 30 minutes on a treadmill or an elliptical machine, do you need to be downing a sugar bomb? Probably not.

Matt D.

The rule of thumb that we say to our athletes globally is, if your workout is 75 minutes or less, you just don't need any calories. Maybe if it's really high intensity, you might have something there just in case. You've got something wrong, and you're having a sugar crash or whatever. But for the most time, 75 minutes or less there's just no need. And you can drink to thirst for the most part, because you're not going to have any of that negative byproducts. But it is what you do afterwards that becomes really important. For a workout that's lasting multiple hours and is training and is interval driven, well then there's a case of like, okay, what's the strategy that I need to employ there to make sure you're maximizing performance, and you're not creating too much of a deficit that's going to have a lag into the rest of your day?

Geoff

Yeah. I think a lot of people focus on pre-fuels, but it sounds like especially on the recovery side, I agree with you. Fasting after a workout, unless there's some specific reason why you want to do that, is very stressful for your body.

Matt D.

Yeah.

Geoff

That 30 minute or hour period when your muscles are open to absorbing nutrition is a pretty critical time period.

Matt D.

Mm-hmm (affirmative).

Geoff

I don't think that's controversial. Anything interesting there, would you say a standard carbohydrate protein shake is kind of standard practice? Any specific nuances? I think you can get kind of nerdy with like, oh, do people care about vegan protein versus whey protein, versus should you just eat a steak? There's been emerging data around how ketone esters paired with carbohydrate and protein accelerates someone to glycogen and protein resynthesis enzymes. Anything interesting in playing around there for post-exercise nutrition?

Matt D.

A general rule of thumb, again, for the time starved busy person. It has to be simple, able to be executed, and easily absorbed. If you've got a very heavy training session, and then we tend to go carbohydrate, protein, easily absorbed. A protein source is a shake. But for the vast majority of people, you sort of point before the person going to the gym, the person doing strength, eat real food. It's a great opportunity. We have too much processed food in our life anyway, so if you get the opportunity to eat real food, it's great. We tend to lean more post-workout fueling of, that's a good time to actually have some of your carbohydrates that you're going to have in the rest of your day. Protein is always there, and a part of that is we know that protein is a natural suppressor of cortisol, which is obviously suitably elevated to help you perform. But you don't want to carry that into the rest of the day. We tend to be a little less on things like antioxidants, which tend to disrupt-

Geoff

Once again, blunt adaptations.

Matt D.

Blunt adaptation. So we tend to try and avoid people having lots of berries in their shakes, et cetera.

Geoff

Interesting.

Matt D.

But it doesn't mean antioxidants are bad. They're great in the rest of the day, they're full of vitamins and minerals, et cetera. It's the timing of them. Simple actionable stuff. I have never tested ketones as being a part of the process. All I've done so far is read Brianna's paper.

Geoff

Okay, yeah, we've got to get some actual data from you there.

Matt D.

Yeah.

Geoff

I think that resonates true with me personally. I like doing fasted workouts and fueling afterwards, which I think is a reasonable response in terms of draining out remaining lycogene, and then post-recovery you have full repletion of all those nutrients. That's more for longevity and metabolic stress reasons than for winning.

Matt D.

Yeah, winning anything. I'm not trying to win anything either. The other thing as well is I tend to, when I work out I work out in the morning. I just don't do well with food in my stomach. So you wake up naturally fasted. You go and exercise or you go and train. Then it's a great time to fuel the rest of your day and replenish. Even from a life structure, I think it's a really good thing in performance during. The only component, there is some research for female athletes and some of the negative hormonal byproducts of not taking in some calories, particularly protein, first thing in the morning.

Geoff

Interesting, yeah. There's definitely some variation in terms of how much body fat per gender that you want to maintain, absolutely.

Matt D.

Yeah, exactly.

Geoff

I know that a lot of our audience are high performance athletes, but people like myself, I'm not a professional athlete. I don't have any dreams or delusions of winning Kona. I consider myself more of a creative or intellectual worker. Do some of your training protocols, nutrition protocols, modalities apply to that world? How do we optimize our training, our routines to be move productive members of modern society?

Matt D.

I sort of have a Jekyll and Hyde life as a coach, and really our Purple Patch coaches have to live the same as well. On one side, I have my squad of pro athletes, and unapologetically, their quest is world class performance. But the majority of people that I work with outside of that people are very busy executives and CEOs that are looking to do just that. They understand the value of integrating fitness into their life, let's call it that. But how do they do that where it can have a net positive effect on their health and their cognitive ability, decision making performance, let's call it, in the workplace. Then also, still be able to return and be really present for their family. I think that's a utopian but achievable ideal. The lens that I take on that is, how do we draw the lessons from the methodology that we use for these elite athletes that are looking for fantastic performance, physiological fitness performance? How do we draw the lessons from that and translate and apply?

You don't just replicate, but translate and apply to someone that's just looking to thrive in life? Some of the key components if you imagine sort of, we always talk about in terms of an intersection of a Venn diagram, where in the busy working professional that's going to thrive, they have to have three main components. The first is their habits around what they're doing in the workplace. There's all sorts of really interesting emerging research of how to be most effective in the workplace. It used to be not so many years ago, probably aligned actually with the bubbling up of the interest in recovery, where effectiveness in the workplace was measured by the number of hours that you're actually doing, and toughness. And what we realized by working with so many executives and CEOs is toughness is not a differentiator. That's just a prerequisite.

Geoff

Everyone's tough.

Matt D.

Life is not easy, everyone's tough. But really being able to work in effective, both in terms of environment, understanding that you're working in sprints, taking breaks. Looking at things like hydration and realizing your pee breaks are performance enhancers. They're not distracting your effectiveness at the desk. Moving around, we obviously know things like standing desks and things like that. The key to actually consistently move around. Your Apple watch will tell you to get up every hour, for example. So there's a big bucket of what you do there. There's then I would say training. I mentioned this before. Just because you exercise, it doesn't mean you're healthier. Just because you get up every morning and go to the gym, it doesn't mean that that's actually creating positive adaptations or helping you thrive in the workplace. I think every human being needs to train. That doesn't mean they have to be trying to search and win Hawaii. It doesn't mean that they have to sign up for an event.

Matt D.

I think a goal of some nature makes it easier to adhere to. But their exercise that they're doing, the same as anything in life, will be more effective if it's structured and progressive. You draw from athletes not to become an athlete, but to actually get the most out of your sessions. If you are exercising four or five times a week, what are the sessions that are designed to move the performance needle and be more challenging? What are the sessions that are there to be more therapeutic emotionally and physiologically, and help support those key sessions? You don't need to be obsessive about it. You don't have to be evangelical about your fitness, but structure and progressive is key. I have never seen someone over the long term be highly effective in that area without having real structure behind it. One of the limiters of general group fitness, you get fitter and quick results over six weeks, and then what's the next thing, because everyone plateaus.

Geoff

You plateau, right.

Matt D.

Longevity and consistency can only happen if you have periods of progressively load, and then you have breaks to rejuvenate and step back. Not dormant, but breaks in the stress.

Geoff

So you're saying that, okay, you probably going to the gym 30 minutes or an hour a day is at least better than sitting on your butt.

Matt D.

It is.

Geoff

Right, that should be obvious. But you oftentimes see people plateau, so having some sort of progression and cycle or periodization around challenging yourself is maybe a little bit more incremental work but pays much more dividends, is your argument.

Matt D.

There's also loads of other benefits from it as well. One of the great components of training, if you want to call it that, it's almost in a therapeutic from a mental standpoint. Almost carries what meditation should do as well, and is a great performance inclusion. We didn't talk about it, but I think meditation is key. If you have structure around your workout those 30 minutes, it forces you to be present. If you are present or focused, then it removes you from the stresses or family or work or commitments. Outside of the dishwasher effect of your brain that's going to improve cognitive function, decision making, long and short-term memory and focus, it also removes a step away from you. That's key as well. So absolutely to be effective, you have to be structured. Every day should not be the same. Otherwise, the body won't adapt, because it gets used to the adaptations. But then the third bucket is rejuvenation, not recovery but rejuvenation.

Matt D.

That includes what we talked about with a backbone of healthy eating habits and fueling habits, positive sleep in terms of quality and quantity. But I think also another venue for the high performing individual to remove themselves from the rigors of work. That might be building model airplanes. It might be meditation. But there has to be an escape. When you get the connection of those three components, where you have great habits around fueling and recovery and rejuvenation, tied in with appropriate and integrated training. It can't just be dumped on top of life, it has to be integrated into life. And positive work habits, something happens every single time, they accelerate. Yeah, they improve in sport, but they also become better at decision making, better leaders, more effective, and they start to join the dots. The final thing I will say about it, which I think is most interesting is when I've worked with so many CEOs, it's the same tools and mindset that they would apply to setting up their business strategies. All of the lessons that they have as a business leader, they already know them. But most of them do a very poor job of connecting the dots to themselves.

Geoff

To themselves, yes.

Matt D.

We have a saying, "Coach our pros like CEOs, and our CEOs like pros." Once they join the dots, they realize, how can I have been such a dip shit? It's all basic and habit driven, it's not overly complex. They start to join the dots between the parallels of that. If you look at the traits of a high performance CEO, for example, and you look at the personality traits of everything that makes a professional athlete, they're exactly the same.

Geoff

The same, yeah.

Matt D.

They're exactly the same. They continually cross pollinate, and just look at each other.

Geoff

It's interesting, you're essentially an executive coach or a life coach with a vehicle of training, which is interesting. I think there's a couple nuggets in there, especially around the structure of training, making sure that you're actually meditative or present when you're training. That just reminds me when I am at the gym, I see so many people in between their sets on their phone, checking social media or Twitter, or any of that stuff. I've been guilty of that myself.

Matt D.

They're missing a chance.

Geoff

Do you think that that distraction has really popped up in the last couple of years that you didn't see 10 years ago? Do you just feel that people are just a lot less present now? You have to just retrain people's mind more aggressively today versus 10 years ago?

Matt D.

I think we've fallen into a trap of feeling that we always have to be connected to be effective. The truth is the antithesis of that. I think you have to be really programmed to be effective. A great example of that is email. We always feel like we have to respond to email straight away, and hand up I'm also guilty of that. Versus, we know that the most effective way to use an information transfer tool, which is email, is to do it in blocks of focus.

Geoff

Block it off, yep.

Matt D.

And then turn it off, so that you can be present on task. The same applies with exercise as well. Can you imagine if I said to you, "All right, we're all going to go and meditate, and we're going to go and sit in a room, but we're all going to be on social media." You'd say, "That's insane." The same applies, because exercise or training is not meditation, but you are spending some of your valuable time.

Matt D.

For many people, time is our most precious commodity, you are deciding to spend this time on something that you know is really valuable for you. But you want to get the biggest results, and the best way to get results is to execute as intended. The only way to do that is to be present. It's why I banned cell phones from our indoor cycling classes. I need people to be present. Then when they come back-

Geoff

Do people listen to music?

Matt D.

Music is a tool in training, as another one that's really interesting. Similar to our nutrition discussion, it depends on the training session. I think music is a great motivator. We know that it can lift mood, it can lift performance if we're happy and we're enjoying-

Geoff

But it can be distracting.

Matt D.

It can't be a distraction.

Geoff

I've almost took it off, just so I get distracted. I don't like the song lyrics, then you just get thrown off.

Matt D.

Exactly. For me personally, I'm not a fan of, "Hey I'm a coach, listen to me because it's what I do." But there are certain sessions where if they require focus, where they're really interval driven, then the best thing might be some music to help maximize performance. But you're not listening to a podcast there, for example. Versus, if I go for a trail run and I'm getting some byproducts, physiological benefits by being out there for an hour or whatever it might be, but I'm not really training per se. The purpose of that session is for me to move my body, have fun, and be a release, go listen to a podcast. It's a great way, because that's feeding my soul as well with something that's interesting.

Geoff

Yeah, very balanced, very wise. You've dropped a lot of interesting nuggets out there. How do people find you or learn more about Purple Patch, learn more about you and all the things that you offer?

Matt D.

Our website is purplepatchfitness.com, but I think the easiest way is probably the Purple Patch Podcast actually. We do a weekly podcast, and it's not about triathlon training, it's about the subject of performance globally, and it's only education. One of the things that's right since the inception of Purple Patch is the passion for education. I think that's a great venue to listen, and I love to hear thoughts. We answer questions every week. I love it when people engage and participate. So either head to the website or listen to the podcast. We appreciate if you share with your friends and family if you find it valuable.

Geoff

Yeah, if you enjoyed this conversation, head on over. Matt's got some wisdom to share here. Thanks so much for dropping by the H.V.M.N. Podcast.

Matt D.

Really great fun. Thanks so much, really appreciate being here.

Geoff

Thank you. Cheers.


Gut Checking Your Heart Health

Originally published on HVMN.org (https://hvmn.com/blog/nutrition/gut-checking-your-heart-health) and authored by Nate Martins on Feburary 27 2019

Heart health is a hotly debated topic—and rightfully so. Heart disease is the leading cause of death in the United States.

The medical community remains committed to studying heart health, attempting to provide the public with analysis and solutions to some of their most pressing concerns. How much does family history play a part in heart health? How much exercise should I get? Can I really eat all those “healthy” fats?

There isn’t a single answer. And over time, even the gold standard proposed answer can change.

Remember when eating fat was the enemy? Counterintuitive as it may seem, we now know that eating more fat might lead to weight loss,1 which can reduce risk for a number of heart-related illnesses. This is just a singular example of how we learn, how studies change, and how advice medical professionals may give based on those learnings will also, undoubtedly, change too.

Point is, the medical community has spent centuries studying heart health. Even still, if you’re looking for an answer to the question “What makes a healthy heart?” you’ll get a library’s worth of different answers.

Let’s look at some of the most common concerns about heart health, and use scientific studies to analyze their merit.

A Portrait of Heart Disease

Heart disease is a shapeshifter manifesting itself in various forms. It’s a catch-all phrase for numerous conditions.

Over 600,000 people every year die of heart disease in the US, with coronary heart disease the most common (killing 370,000 yearly).2

In men and women, about 40% of these deaths are related to what’s called “ischemic heart disease.”3 This occurs when the arteries of the heart cannot deliver enough oxygen-rich blood to the heart. Conditions caused by atherosclerosis (hardening and narrowing of the arteries) include coronary heart and artery diseases, leading to heart attacks and potentially sudden death.

About 35% of heart-related deaths in men and women are caused by brain-related cerebrovascular disease.3 These conditions are also caused by atherosclerosis, but instead the blockage of blood vessels flowing to the brain. This can lead to a stroke, in which the brain is deprived of oxygen and parts of the brain can become permanently damaged (or even results in a permanent disability / death).

Collectively, in men and women, inflammatory, rheumatic and hypertensive heart diseases account for less than 10% of heart-related deaths.3

Inflammatory heart disease can be caused by various infections, viruses, bacteria or other toxic material. Essentially, this is an infection of the heart, and sometimes, its origin isn’t found. Rheumatic heart disease relates to damage to heart valves, often a complication of rheumatic fever which is usually a condition suffered most commonly in children under 15. Hypertensive heart diseases are associated with high blood pressure, in which the heart works under increased pressure, leading to problems in the arteries and muscle.

The remaining ~15% of heart disease-related deaths are caused by various conditions like congenital heart disease, cardiac arrhythmias and heart failure.3

Dietary Fat

For years, fat was villainized. Low-fat-this and low-fat-that became popular dietary staples in fear a diet high in fat would be the culprit of an unhealthy heart. But now we better understand only certain types of fat can be dangerous, and a diet of healthy fats can foster a healthy heart. Increased fat consumption is not always associated with cardiovascular disease.4

There are several different kinds of dietary fats.

Saturated fats are solid at room temperature, like in butter and coconut oil. Historically, it was recommended to limit dietary intake of saturated fats because it was thought to be associated with heart disease. But emerging research illustrates increased consumption of saturated fat can have beneficial effects on blood biomarkers, like increasing healthy HDL cholesterol levels.5

Unsaturated fats are liquid at room temp, like in vegetable-based fats such as olive oil. They’re typically thought of as the healthy fats, and increased consumption of mono and polyunsaturated fats have been linked to improved blood biomarkers like lower blood triglycerides.6 When people talk about “good fats,” they’re likely referring to monounsaturated and polyunsaturated fats. These have fewer hydrogen atoms than saturated fats, and can be found in vegetables, nuts, seeds and fish.

What you want to watch out for are trans-fats. These are produced artificially when hydrogen is added to unsaturated fatty acids in order to solidify them and increase shelf life. Associations with poor health outcomes forced the FDA to remove their GRAS (generally regarded as safe) status in 2015.7

How does fat help or hurt your heart? It has to do with lowering LDL (bad) cholesterol, which can line arteries and cause atherosclerosis, a blood vessel disease that can lead to heart attacks and strokes.

One review showed that reducing saturated fats, and replacing them with polyunsaturated fats, reduces coronary heart disease events.8 But another study showed inconclusive results when analyzing the effects of saturated fat consumption on vascular function, diabetes and stroke.9

While it seems fat isn’t the devil it was once cast, it’s still important to monitor dietary fat and focus on consuming unsaturated fats.

Exercise

Just like biceps or quads, the heart is a muscle. With regular exercise, it can become stronger, better able to pump blood throughout the body.

Before getting into all the positives about exercise for the heart, there are a few considerations.

Heart problems rarely occur due to physical activity; however, cardiac arrests and heart attacks are possible, but these usually occur in those who already have some type of heart condition, especially those with congenital heart problems (meaning, they’ve had these problems since birth).

Rarely, heart problems occur as a result of physical activity. Examples of these problems include arrhythmias, sudden cardiac arrest, and heart attack. These events generally happen to people who already have heart conditions. Fitness level can also play a role.

However, the benefits of exercise for the heart seems to far outweigh the risks.

Overall physical activity, including running, weight training, and walking are associated with reduced risk of coronary heart disease (CHD).10 The opposite of a healthy, active lifestyle is a sedentary one (one many people live!). A sedentary lifestyle increases risks for death from CHD, according to a meta-analysis.11 But there’s a “Goldilocks effect” when it comes to exercise—too little exercise is bad, and too much exercise can also be bad.

While it’s inconclusive the best type of exercise to promote heart health, there isn’t anything inconclusive about the efficacy of exercise. Anywhere from 60 minutes per week to 150 minutes per week (for those who are able) is prescribed by the National Heart, Lung, and Blood Institute.12

Family History

Many people think they may be at risk of heart disease based on their family history. It’s even one of the boxes you may check when filling out a form in a new doctor’s office.

Family history is a complex risk factor for heart disease. There are many, many genes that control how your heart works, and small changes can have important effects on the function of the heart. Start by looking at your immediate family’s health, and go outward from there. Genes are, unfortunately, inescapable. But they don’t explicitly predict your bill of future health.

Part of the reason doctor’s ask about family history is to help them understand what you may be susceptible to. That way, you can focus on specific strategies to fight against your genetic hand.

Even though there isn’t one genetic fingerprint tightly linked to heart disease, some studies do show a strong correlation between family history and coronary heart disease.13 Some point to an especially strong relationship between heart disease and first-degree family members.14 Others illustrate the problems with linking family history to heart disease, especially in relation to the number of family members with heart disease and an understanding of what, specifically, that heart disease was (leading to misunderstandings about how family history impacts CHD).13 The conclusion? This study denotes how difficult it is to showcase the connection, suggesting that family history and CHD remain largely unexplained.15

At its core, this one is difficult to unpack.

Other Risk Factors

Numerous other risk factors exist that may lead to heart disease. Many of these are related to the conditions above, but they warrant a bit of further exploration.

Diabetes

Diabetes occurs when blood glucose (or blood sugar) levels are too high. Insulin in the hormone that helps shuttle glucose into cells for energy. Type 1 diabetics don’t make insulin (assumed to be caused by genes, or environmental factors like viruses). Type 2 diabetics don’t respond to insulin (assumed to be caused mostly by lifestyle factors and genes).

Overtime, high blood glucose can damage blood vessels and nerves that control the heart.

The National Institute of Diabetes and Digestive and Kidney Diseases claims diabetics have a higher chance of developing heart disease, and have a greater chance of having a heart attack or stroke.16 It seems diabetes increases the risk of all clinical manifestations of CHD.17

There doesn’t seem to be much debate here. The longer you have diabetes, the higher your chances of developing heart disease,18 and those with diabetes are almost twice as likely to die from heart disease or stroke.19 But it’s not clear what to do about this risk, as intense blood sugar control doesn’t appear to reduce the risk of heart disease in diabetics.20

Blood Pressure

When most people think of blood pressure, they think of high blood pressure. This means the force of the pumping blood in arteries is higher than it should be. But how’s this relate to heart disease?

Excess strain from high blood pressure narrows and weakens coronary arteries. Often this is because of plaque in the arteries, basically a buildup of fat and cholesterol (among other things), increasing the risk for a blood clot. When an artery is blocked, blood flow is compromised, and the heart becomes starved of oxygen, resulting in a heart attack.

High blood pressure increases risks of cardiovascular disease.21 It may also cause a stroke (on conjunction with other factors).22 More exercise and changes to diet are often prescribed to help alleviate high blood pressure.

Cholesterol

We’d need a whole article to analyze how cholesterol affects heart disease.

Cholesterol is essential to healthy cells, making hormones, making vitamin D and supporting digestion—but having too much of the “wrong” type in your blood can increase risk of heart disease. Simply speaking, cholesterol, found in dietary fats like meats and dairy, has two types.

HDL is the “good cholesterol,” helping the body rid itself of excess cholesterol and ensure it doesn’t end up in the arteries. LDL is the “bad cholesterol,” collecting in the walls of arteries and leading to plaque. When too much cholesterol builds up in artery walls (a process called atherosclerosis), it can cause a heart attack.

Studies have shown total cholesterol / HDL ratio is better at predicting risk for CHD when compared to total cholesterol or LDL cholesterol levels.23 Furthermore, one study bucked the LDL trend but showing that high LDL cholesterol was inversely associated with mortality in most people over 60.24 But other studies have shown lower HDL cholesterol levels were found in persons with CHD when compared to those without the disease.25 And some studies have pointed to low LDL has being a strong indicator of CHD.26

Studies seem to show inconclusive results for LDL and HDL levels in heart disease. You can learn more here, on our recent episode of the H.V.M.N. Podcast with Dave Feldman (also known as Dave Keto).

Assessing Your Heart Health

There are many, many factors influencing heart health; lifestyle, diet, family history, all these things play a role in what’s a complex medical issue.

Start with consulting your doctor to understand risk factors. Since February is American Heart Health Month, there’s no time like the present.

Optimize Running Cadence to Improve Performance

Article originally published on HVMN.org (https://hvmn.com/blog/training/optimize-running-cadence-to-improve-performance) and authored by Brady Holmer on March 12, 2019

Nutrition, training, recovery. These three pillars of training are non-negotiable, and most athletes work hard to optimize them. However, there may be smaller tweaks you can make in running technique to reach higher levels of performance if you’ve hit a plateau.

Running cadence may be the next tool you can use to achieve a new PR.

The Importance of Cadence

Music has tempo. Songs have a unique beat you feel, a strong vibe to which you can’t help but nod your head.

Runners, like music, have tempo–called cadence.

Cadence, also known as stride frequency, is the number of steps taken per minute while running. While stride length refers to how long each particular step is, cadence measures the number of times your feet hit the ground.

Cadence is a highly-researched topic in sports science. Given its influence on many aspects of running (like injury risk, foot strike patterns, and oxygen consumption), cadence is something you should learn to train and optimize in order to reach new running levels.

How to Determine Running Cadence

Finding natural running cadence is simple, and can determine whether you might benefit from an increased or decreased step frequency. All you need is a stopwatch. Many running watches now come with a function that measures cadence for you, removing the need to count steps on your own.

While running with a natural cadence, count the number of steps taken in one minute. At the end of 60 seconds, the number of steps taken is your cadence. Another option is to count how many times your right foot contacts the ground in one minute, and multiply by two.

Don’t try to artificially manipulate your run cadence during this test; find your natural cadence. You can even repeat this measurement as you run at different speeds. This allows you to observe stride rate changes as you run faster or slower. Measure cadence on different runs, like a long tempo or a quick interval workout, and see the difference from a recovery run.

180 Steps per Minute: The Gold Standard?

Anyone familiar with running has probably heard of the long-held belief that 180 steps per minute is the ideal stride frequency, developed by legendary running coach Jack Daniels. Daniels observed that, on average, the elite runners typically run at a cadence of ~180 steps per minute. Since runners love to mimic what the elites do, it comes as no surprise this number was accepted as cadence dogma.

This number may represent an optimal cadence for some, but doesn’t serve as a rule of thumb for running cadence. Running cadence is influenced by a multitude of individual factors, and runners at all levels will have varying cadences, even at the same speed. Don’t stress if your running cadence isn’t near the magic number of 180 steps per minute.

Cadence can even depend on footwear. One study compared running cadence in a barefoot condition and a standard shoe condition, finding that cadence was around seven steps per minute greater (184 vs 176 steps per minute) when barefoot than in standard running shoes.1

World records and Olympic medals have been achieved in various distances with cadences as low as 170 and as high as 212. Individual variation in cadence exists. However, there probably is an individual optimal frequency for each runner. Finding and training this cadence can occur with practice and a bit of fine-tuning.

Running Cadence and Performance

Given the large variation even within a single runner, a simple measure of steps per minute might seem to have no performance relevance. Isn’t increasing stride rate just a matter of running faster? Turns out, running cadence has more of an impact on physiology and running form than you may think.

Sub-optimal running cadence can negatively impact performance.

A run cadence that is too low results in long strides and a greater risk of injury. A cadence that is too fast leads to choppy strides and sacrificed efficiency.


Metabolic Cost

Efficient use of oxygen during endurance sports is critical for performance. Even though freely-chosen cadence is found to be efficient for most, any shift closer to optimal leads to a reduced V02 (oxygen cost) at the same running speed. Efficiency increases along with running cadence.

Studies found most recreational runners self-select a running cadence resulting in an increased energetic cost of running. Basically, runners aren’t self-optimizing cadence. When forced to run the “optimal” cadence, running cost for novice and elite runners was reduced around 1% - 5%.2 This boost in performance is considerable when talking in terms of seconds and minutes saved during a race. Those small percentages may make the difference between a decent race and a great one. Cyclists using H.V.M.N. Ketone performed 2% - 3% better in a 30-minute time trial, going 400m further.3

An optimal cadence also minimizes heart rate at the same speed, suggesting a lower energetic cost and effort of running. A study suggests that runners who increased their running cadence above their self-chosen cadence can immediately reduce HR. In this study, 164 steps per minute was found to be the most efficient.4

Synchronizing Cadence with Heart Rate to Improve Efficiency

The idea that running efficiency (and hence performance) can be improved by coupling stride rate to the heart rate during exercise is known as “cardiolocomotor synchronization.” Essentially, it means timing your foot strike to occur in line with the contraction and relaxation of your heart.

Timing the foot strike to occur during diastole (when the heart relaxes) is hypothesized to improve blood flow, reduce stress on the heart, and lower the energetic cost of running. Elite male distance runners who adopted cardiolocomotor synchronization reduced their heart rate when their foot strike occurred during the relaxation phase of the heart, compared to a foot strike during contraction.5

Direct timing of these two processes may require invasive measurement, however, studies have shown most trained distance runners approach a 1:1 ratio of cadence and heart rate.6 You can use this rule of thumb to experiment with cardiolocomotor synchronization. Use a HR monitor during your runs, and manipulate your step rate to match your watch. This might be more applicable at intensities above 160 bpm since it will correspond more naturally to your run cadence.

There is direct evidence that synchronization works for performance enhancement. A pilot study of runners who synchronized cadence to heart rate led to an average improvement of 35 seconds in a five-kilometer race.6 They used an adapted headphone set linked to a heart rate monitor so they received real time feedback of how they should change stride length to match heart rate and weren’t too distracted. Seems like a cool way to hack a PR.

Fatigue Impacts Cadence

You’ve experienced the feeling of muscle fatigue in the late stages of a race. While hurtful to performance, muscular fatigue can also impact running cadence.

Studies in which participants have undergone “fatiguing” treadmill runs observe a decrease in stride frequency as runners become more fatigued.7,8 A lower cadence is accompanied by an increase in stride length (overstriding). In the same study, lowering cadence resulted in decreased loading forces even with the presence of overstriding. This might represent a fatigue-induced loss of capacity to produce optimal force and thus maximize performance capabilities. This comes at a sacrifice to running economy.

These findings highlight the importance of cadence awareness. In the race’s final miles, it may be important to mentally note stride rate at various points to see when you might unconsciously decrease cadence.

Manipulating cadence reactively when tired can prevent performance declines brought on by fatigue. When the number of steps you take starts to decline, take notice and change your running form.

Running Cadence and Injury Prevention

Runners sustain injuries, many of which stem from biomechanical factors related to cadence. These include stride length (overstriding) and problems that arise because of large loads placed on joints, tendons, and muscles that lead to overuse injuries.

Preventing Overstriding

Overstriding refers to the foot landing too far in front of a runner’s center of gravity. Some definitions propose that running form categorized by overstriding occurs when the landing foot spends too much time ahead of the center of gravity. Overstriding reduces running efficiency and places greater loads on joints and tendons, increasing risk of injury.

As cadence increases, stride length decreases; a quicker cadence is a way to prevent overly-long strides.

This is one of the ideas behind barefoot running, which naturally reverts runners to a quicker stride rate. Studies have indicated quicker cadence (even in normal running shoes) may mimic some of the beneficial effects of barefoot running, including shorter stride length and a foot strike closer to the center of gravity.

Light on Your Feet

Reductions in total load placed on the foot (plantar loading) were observed in runners who modified cadence to be 5% faster than preferred stride frequency.9 Specifically, a faster cadence led to reduced ground contact time, contact pressure, and force variables placed on the heel and metatarsal foot regions. A two-hour half marathon involves over 20,000 foot strikes–the stress adds up. Any small reduction in force per foot strike means your feet will thank you later.

Coordinating Gait

With each stride, parameters such as stride length and knee flexion undergo significant variability. Small changes in running technique can occur even within a single long run. For optimal efficiency, runners need to coordinate the movements of each individual leg component during all gait phases.

Inconsistency in gait coordination (higher variability) is seen in neuromuscular disorders and is also associated with higher incidence of running injury. Increasing running cadence has been shown to decrease measures of coordination variability (a good thing),10 theoretically decreasing risk of injury.

The Bee’s Knees

Manipulating running cadence to be 5% - 10% faster results in less mechanical energy absorbed at the knee by 20% - 34%, with lower loads correlating to increased cadence.11 Hip joint loading was also reduced when cadence increased by 10%. This is because a higher cadence reduces running kinematic variables such as center of mass, breaking impulse, and knee flexion angles. Even subtle increases in step rate (in this study, between 8 - 17 more foot strikes per minute) can significantly reduce loading on joints.11

How to Train Your Running Cadence

Should you change your running cadence? It depends. Many studies show whatever cadence runners freely adopt very likely is their optimal cadence (or even least something close to it).

Our bodies might automatically adapt to changes in various running conditions, muscular factors, and fatigue to find the sweet spot of stride frequency that works for us.12

Running cadence is reflexive. Miles of training hardwired a specific running cadence into your brain and biomechanics. Any attempt to change cadence must be systematic and approached with caution.

Rules of the Road

Research indicates most runners benefit from increasing cadence by 5% - 10% above their current self selected running cadence.11 This change is also shown to reduce running injuries.

To determine what your increased cadence looks like, take your current running cadence (for example, 170 strides per minute) and take 5% (or 10%) of this number.

170 x .05 = 8.5

Add this number to your current cadence to determine your new, higher running cadence.

170 + 8.5 = ~178 strides per minute for a 5% increase in cadence.

Developing a quicker cadence requires more than just willing your feet to move faster. The following drills and techniques for training cadence can be implemented into your running routine a few times per week. Perform these drills after a sufficient warmup or after a workout to improve running cadence and ingrain new patterns into your brain.

Music

Find songs with tempo corresponding to what your optimal running cadence should be. A simple search for “180 bpm songs” gives a slew of examples you can add to your playlist. Research shows runners spontaneously entrain stride rate to the tempo of music they are listening to, even when the changes in the beat aren’t noticeable.13

Metronome Training

Setting a metronome to your desired running cadence may also be a useful drill to train a faster or more natural stride frequency. While running on a treadmill or outside, synchronize your cadence with the metronome and foot strikes with the ticks. At first, it may be ideal to use a metronome intermittently during runs. Run with the metronome cadence for one minute and alternate this with your “natural” cadence for several minutes.

Hill Sprints

Running on an incline requires shortening stride length and naturally increasing cadence. Training faster cadence using hills minimizes impact forces (compared to downhill or even-ground running), which can reduce injury risk associated with higher intensity and higher impact running.

High Knees and Quick Steps

A higher running cadence means your feet will need to contact the ground quicker. Two key concepts here are faster turnover and lower ground contact time, and drills can be done five or six times weekly, either before or after a workout.

High knees involves bringing your knees to about chest level (or 90 degrees), moving your feet up and down as quickly as possibly. Focus on arm movement too, as quicker arm movement will also help entrain quicker steps and faster turnover. High knees can be done in place or while moving forward (slowly) for 20 yards at a time.

In quick steps, find a ~20 yard stretch of asphalt or turf (a football field works perfectly). While lifting feet only slightly off the ground, progressively move forward, trying to increase the speed of your foot contact to achieve a faster turnover every five yards.

The Optimal Frequency is the One Which Suits You

We’ve dismissed the notion of 180 steps per minute as the magic running cadence number. So...what actually is the optimal stride frequency? Ultimately, there is no single number. Most studies find a general range of between 160-190 steps per minute as the naturally adopted frequency for recreational runners and elite athletes.

Most runners have room for improvement. The optimal stride frequency for many runners is probably 3% faster than their preferred cadence. Running economy isn’t usually affected by the 3% reduction in stride length that comes with increasing cadence, but any change over 6% might be detrimental.14

There may be an energetic benefit from increasing stride rate and consciously changing your stride frequency depending on the type of runs.

It may take around 6 - 8 weeks for the muscle memory of a new cadence to take effect. Try to run around 50% of your weekly training mileage at the cadence for which you’re aiming. And start slow; rather than immediately bumping up cadence to 10% above normal, start with 2% - 3% per week until your reach 10%.

Find Your Rhythm

As you experiment with different running cadences, a new natural cadence will likely develop after the proper patterns and changes have become habitual. While efficiency might take a hit when first transitioning to quicker strides, eventually you will be able to sustain a higher stride rate with more efficiency and less effort.

In the spirit of self-experimentation, running cadence is an investment strategy with proven benefits. Find your rhythm.

Overtraining Syndrome Can Sabotage Performance

Originally published on HVMN.org (https://hvmn.com/blog/training/overtraining-syndrome-can-sabotage-performance) and authored by Brady Holmer on March 12, 2019

It’s two weeks away from marathon race day. Legs should feel fresh, mind should be focused, and fitness should be at an all-time high. This is what you’ve trained for the past several months, never missing a workout. It’s time for all of the hard work, dedication to diet, and mental preparation to pay off.

But things feel off. Nailing goal workouts is difficult. Running similar times requires more effort. Fatigue is chronic despite adequate rest. Muscle soreness lingers.

Taking a week off from training doesn’t help and on race day, a personal record feels impossible. You start the race with little enthusiasm, each of the 26.2 miles spent thinking about the finish line. Rather than running a fast time, the goal becomes simply to finish. The excitement of the race is gone.

These symptoms represent a classic case of “overtraining syndrome” or OTS. OTS is something that many athletes may suffer from but may know little about.

What is Overtraining Syndrome?

Training dedication is important. But if you overtrain, you may not even make it to the start line.

Overtraining and Overtraining Syndrome Defined

Operationally, overtraining is defined as a training imbalance where stress > recovery.1 When high levels of physical activity or high-intensity training are paired with inadequate rest and recovery time, performance suffers.

A separate but related condition to overtraining is known as relative energy deficiency syndrome in sport (RED-S). This syndrome results from an imbalance between dietary energy intake and expenditure. RED-S is characterized by loss of general health, proper growth, and reduced sport performance.2 Many physiological functions such as metabolism, menstrual function, bone health, immunity protein synthesis, and cardiovascular health are negatively impacted by RED-S. This syndrome may be an early precursor to full-fledged overtraining syndrome.

Short-term overtraining is reversible with a proper rest period. In overtrained athletes, a rest period of one or two weeks can reverse many symptoms and lead to a performance rebound. This distinguishes overtraining from the more severe overtraining syndrome (OTS).

Overtraining syndrome results when overtraining continues for an extended period of time; some might call it burn out.

Since OTS is more severe than overtraining, recovery time is longer. It may take a rest period of weeks or even months to reverse OTS, maybe because it’s usually coupled with other types of stress: high altitude living, training monotony, suboptimal diet, and academic, occupational, or relationship strain.

Overtraining, or Under Recovery?

For athletes, the concept of overtraining might seem odd. You understand a high training load is needed to adapt and get better (known as “supercompensation”). However, too high of a training load with too little recovery is a poor way to achieve proper gains. Recovery is when the actual training adaptations occur, not during the training session. In fact, sometimes overtraining may not even be evidence of training too much, but recovering too little.

Your Brain and Body on Overtraining

It’s well documented that mental strain can have physical impact. When the mind wears down from overtraining (or stress outside training), it can impact performance negatively.


Negative Mood States are Higher in OTS

The mental side of training and recovery are equally important as the physical. Overtraining can have wide-ranging effects on mental health and motivation, which can negatively impact day-to-day training and performance in competition.

One of the early signs of overtraining might be large emotional swings accompanied by more negative thoughts than normal. Mood changes likely occur due to alterations in endocrine hormones and changes in the nervous system.

Ultramarathoner and H.V.M.N. Athlete, Jeff Browning, has been there. He says there are a lot of puzzle pieces to running 100 miles and the mind is a big piece.

“I don’t let negative talk take root. I’ve learned to slay mental dragons by constantly switching to positive speak. That’ll give you an improvement in performance.”Jeff Browning

Overtrained athletes exhibit higher levels of negative moods like tension, depression, anger, fatigue, and confusion. They also have lower levels of positive mood states such as vigor and motivation during training.3 One study observed that in a group of athletes suffering from chronic fatigue, 80% had levels of clinically significant depression.

Overtraining may also cause feelings of edginess with symptoms of insomnia, lack of appetite, restlessness, and sleep disturbances. This may seem counterintuitive, since overtraining is usually associated with chronic fatigue, but it likely results from a “hyper-aroused” state. A constant, high release of stress hormones characterizes sympathetic overactivity; this is one reason an elevated resting heart rate is observed in overtrained athletes.

Neuroendocrine Dysfunction

The Hypothalamic-Pituitary-Adrenal Axis (HPA) regulates a majority of our body’s hormonal system. As part of the sympathetic nervous system (SNS), it helps respond and adapt to challenges by releasing stress hormones such as cortisol and adrenaline: think “fight or flight.”

Proper coordinated function of the hormonal and nervous system is critical for athletic performance, helping prepare the body for high-intensity exercise and competition by increasing heart rate and blood pressure and releasing catecholamines (hormones produced by the adrenal glands).

Overtraining syndrome causes central nervous system dysfunction; while release of stress hormones might remain high, their ability to cause the proper response in target organs is diminished. Hormones responding to exercise or low blood sugar are rendered ineffective.4,5

This is the “autonomic imbalance” hypothesis of overtraining. Sympathetic/parasympathetic nervous system dysfunction and insensitivity to stress hormones results in impaired performance during racing and training.6 Overtrained athletes have a harder time performing. This suggests chronic fatigue can have effects in the brain as well as the body.

High-intensity, high-volume training may also result in reduced cognitive processing speed.7 For sports and race situations requiring decision making and composure, this is dangerous.

Heart Rate Variability as a Biomarker for Overtraining

A popular biomarker for athletes to indicate recovery status, heart rate variability (HRV) might be useful to detect potential overtraining. The applications of HRV are discussed at length in a recent H.V.M.N. podcast episode: "What You Can Learn From Heart Rate Variability" ft. Jason Moore.

HRV is a measure of the variability in the time between heartbeats (the beat to beat interval) and reflects autonomic nervous system balance–the balance of parasympathetic and sympathetic nervous system activity. Increased HRV generally indicates a good balance, whereas a reduced HRV may indicate a shift towards greater sympathetic activity due to chronic stress and overtraining.

Along with an elevated resting heart rate, lower HRV is found in athletes who are overtrained.8 This could indicate nervous system imbalances as a result of overtraining/under recovery. Regardless, the underlying problem is too much stress.

Effects on Mental Health

A daily self assessment of mood and well-being might be able to point out a possibility of overtraining or a path toward OTS. Athletes know their bodies well, and a simple mood check-in might be a quick way to assess recovery status.

Feeling a bit off during a workout? Less motivated to train? Recognizing changes in mental state during training can indicate when to dial back the intensity or take extra recovery time.

How Overtraining Influences Performance

A heads-down training approach is something to be admired, and it’s a way many athletes train in hopes of better performance on race day. But it’s a thin line. Overtraining, and not allowing enough recovery time, can actually impair performance.

Training, Racing, and OTS

While no true biomarkers for overtraining exist, one sure sign of overtraining is “an inability to sustain intense exercise and/or a decrease in sport-specific performance.”9

In other words...you’ll suck on race day.

In the short and long term, a state of overtraining in endurance athletes has been shown to decrease time to fatigue by 27%, reduce power output by 5.4%, and increase trial time by 9.8%10,11–it kills performance measures

Along with reducing performance and work output, overtraining increases the effort required to sustain the same level of intensity: running at the same speed feels harder, lifting a lighter weight seems more difficult.

Athletes report a higher rating of perceived exertion (RPE) for the same workload when they are overtrained versus well-rested.12

While endurance athletes are often the subject of overtraining talk, it is important to realize that no athlete is immune. Overtraining syndrome has been observed in endurance athletes, strength athletes, and elite judo athletes.13,14,15

The Immune System Suffers in Overtrained Athletes

Of all the things athletes want to prevent, arriving at the starting line sick or losing training time due to illness are high on the list.

Overtraining severely impairs immune system function, leading to increased risk of illness and infection.16 Being around group of teammates or training partners in gyms, sporting facilities, and public venues only increases this risk by exposing athletes to more pathogens and infectious bacteria.

Depressed immune function and higher rate of infection are consistent findings in studies of overtrained athletes. In particular, athletes training at high volumes seem especially prone to upper respiratory tract infection (URTI),17 a viral infection of the nose, throat, and airways.

The immune system is less able to fight pathogens during overtraining16 due to a lower number of immune cells fighting bacteria. Even the most elite athletes are at risk. Olympic athletes classified as chronically fatigued are shown to have higher levels of infections leading up to the games,18 a period where they are undergoing strenuous training.

Recovery and nutrition strategies targeted at improving immune function may prevent illness during overtraining. Increasing dietary carbohydrate and intake of certain polyphenols (plant micronutrients) are effective in supporting sport19 performance and anti-viral capacity of athletes.

Preventing and Treating Overtraining Syndrome

Taking adequate recovery time to bounce back from overtraining presents a major setback, so preventing overtraining should be one of every athlete’s goals.

However, if you’re feeling overtrained or suffering symptoms of OTS, the first step is to immediately reduce training volume. This might involve low-intensity training or active recovery. In some cases, an extreme amount of rest may be necessary to prevent full-fledged overtraining syndrome from developing.

Below are some strategies to optimize recovery, prevent the onset of overtraining syndrome, and treat symptoms if you find yourself in an overtraining rut.


A Well-Planned Training Program is the Key to Success

The best way to prevent overtraining is to stick to a well designed training program. Athletes in all sports tend to overperform on the easy days and underperform on the hard days.20 Don’t make this mistake

Having a coach or a training partner to provide accountability and support throughout training can be helpful here. A support system can also keep you accountable if you need a few days off. Training partners can encourage the need to rest and remind you bigger things are down the road.

The Importance of Getting Enough Zs

The scientific literature is consistent: the body needs sleep. Inadequate sleep negatively affects areas of performance such as memory and attention, injury risk, speed, and endurance.21 Sleep is often sacrificed by athletes in favor of training or other lifestyle demands, such as travel, competition schedules and work.

Overtraining is associated with sleep disturbances.22 Athletes should pay extra attention to sleep time and sleep quality, following some key strategies to enhance sleep hygiene and promote optimal recovery.

Increase sleep duration by getting seven to nine hours of quality sleep each night (recommended for all adults).

Athletes may need even more sleep due to higher training volumes, as it’s necessary to restore mental and physical functions.

Research indicates that sleep extension improves several measure of performance in athletes.23

Sleep can treat overtraining symptoms too, and is perhaps the best recovery tool available to athletes. Take a few rest days and focus on sleep if you find yourself experiencing training fatigue.

It can help to optimize sleep environment with a cool, dark room, free of electronics and artificial light–all are shown to increase sleep quality. Adding a nutritional supplement such as Yawn from H.V.M.N. into to a sleep routine can further promote high-quality sleep. Ingredients like magnesium glycinate, L-glycine, and L-theanine promote sleep and enhance the recovery process in athletes who may need help getting some proper shut-eye.24

Fuel for Success

Optimal performance and recovery require proper fueling at every stage of training. Inadequate carbohydrate and protein intake, in addition to long term negative energy balance, impair recovery and lead to symptoms of overtraining. Even with proper planning, studies show that many athletes fail to meet a sufficient calorie intake to maintain energy balance25 and might suffer from vitamin and nutrient deficiencies.

Protein is vital for tissue restoration, muscle building, immune function, and recovery from hard training sessions. Athletes in training need more protein to support training and recovery needs. Increased protein intake can also prevent unintended loss of weight in the form of lean muscle mass.

Up to 1.7g/kg of bodyweight in protein should be consumed for athletes in a variety of disciplines such as endurance and strength training to prevent muscle breakdown and support immune system function.

Adequate intake of carbohydrates to support training intensity and promote recovery is another important factor in preventing overtraining. While low-carbohydrate diets may have a place in some programs, sufficient intake of carbohydrate to support high-volume and high-intensity training in athletes is recommended.

Studies provide evidence that less adaptation to training occurs in glycogen-depleted endurance athletes, and that symptoms of overtraining can be prevented by a high carbohydrate intake during times of high training load. Athletes consuming a high carbohydrate diet containing 8.5 g/kg of carbohydrate during a period of high training maintained better performance and mood compared to a group consuming a lower carbohydrate diet containing 5.4 g/kg throughout the same training program.26

What if you are feeling overtrained, sluggish, or in a slump? Try to eat yourself out of overtraining by increasing your calorie intake, consuming high-quality protein sources, and eating foods rich in a variety of nutrients. Energy insufficiency is often a cause of overtraining, and giving your body what it needs can get you back to training.

Track Biomarkers

Staying in touch with yourself on a day-to-day basis will let you become aware when things seem off. Take a daily mood assessment before and after training. Is your attitude or willingness to train more negative than usual?

As discussed above, heart rate variability (HRV) tracking can also let you know if you’re overtraining. Getting your blood work done to test for possible endocrine or metabolic imbalances may be a more in-depth but worthwhile assessment of training status.

Could Ketone Esters Help Prevent Overtraining?

Recently, an increasing number of athletes are experimenting with the ketogenic diet and exogenous ketones (such as H.V.M.N. Ketone) as tools to enhance endurance sport performance and recovery. Strategic use might help athletes avoid overtraining, but there is still a lot of work to be done to understand their full potential.

Early studies suggest that ketone esters might accelerate muscle replenishment.

For example, athletes who added beta-hydroxybutyrate or BHB (the ketone ester present in H.V.M.N. Ketone) to a post-workout meal, set themselves up for enhanced muscle protein synthesis, indicated by increased signaling of the growth regulator mammalian target of rapamycin complex 1 (mTORC1).27

Another possible application for ketone esters is to help the body store carbohydrate in the muscles as glycogen. Replenishment of muscle glycogen was accelerated following ketone ester supplementation when coupled with in IV infusion of glucose.28 The jury is still out here, as another research group didn’t see the same effect on glycogen when the ketone ester was taken with a post-workout shake.27 Because of the powerful effect of ketones on the body, it’s certainly likely that adding ketone drinks to regular nutrition could boost muscle recovery.

Overtraining is a Delicate Balance

Like rain clouds in the distance, overtraining threatens any athlete in a hard training block. Dedication and overuse is a thin, looming line that many athletes don’t realize they cross until it’s too late. For many athletes, it’s probably easier to push harder than pull back.

But perspective is necessary. If you’re worried about overtraining, speak to a coach or friend and hold yourself accountable to get necessary recovery time. Learn to listen to your body for whispers of overtraining. It’s a complex scenario involving mental health, nervous system function, and physical symptoms that decrease performance in the short and long term.

Importantly–don’t beat yourself up about it. A black hole of overtraining can be a dark and lonely place, so getting help is one of the best ways to treat OTS. Be patient, recover properly, know it’s a process and take the necessary steps to try and prevent overtraining before it’s too late.

Lactate Threshold is Misunderstood

Originally published on HVMN.org (https://hvmn.com/blog/training/lactate-threshold-is-misunderstood) and authored by Nate Martins on April 11, 2019

If you want to start a debate in a group of runners, mention lactic acid and lactate threshold. The topics are two of the most confused and misunderstood in the running world. For the last few decades, lactate was presumed to be all bad–causing only muscle soreness and dashing dreams of personal records.

But that’s only half the story.

Lactate threshold is the exercise level at which lactic acid builds up in the blood. This accumulation of lactic acid is associated with fatigue, and most people assume the burning sensation of hard exercise is caused by lactic acid.

Endurance athletes specifically focus on lactate threshold as a measure of efficiency and fitness. For many, the goal of training is to maintain increased power and speed without crossing over this threshold. Most athletes want to stave off blood lactate accumulation, training so they clear it faster and produce less.

That’s why lactate is generally considered a four-letter-word, thought to be a waste product linked to muscle fatigue.

Research on the issue makes muddy waters more clear: producing and burning lactate provide essential fuel for cells throughout the body when oxygen is depleted.1

Lactate & Lactate Threshold Basics

There’s a nuance to lactate responsible for its bad rap.

Lactate: More Protons, More Problems

Lactate can be produced throughout the body naturally.2 It’s a result of rapidly burning carbohydrate when the demand for energy is high, and oxygen availability is low, such as during sprinting or other high-intensity workouts.

Glucose is the body’s most readily available fuel, easily transported around the body and broken down to support short bursts of intense exercise. Glucose gets metabolized by a process called glycolysis, resulting in pyruvate. There are two possible uses for pyruvate: anaerobic or aerobic energy production.

When there is plenty of oxygen, pyruvate is turned into energy in the form of ATP through the aerobic pathway. Without enough oxygen present, pyruvate has another fate: anaerobic conversion to lactate. So all that huffing and puffing during intense exercise is used (among other things) to fuel the metabolic reactions that make our muscles work.

The majority of lactate released into the blood is mopped up in the liver where it can be converted back into glucose via a process called gluconeogenesis, and then released back into circulation.1 For example, the brain can directly use it as fuel (along with other parts of the body).

Lactate itself isn’t at all that bad for the body. The bad part is the acid associated with it.

Lactate caries a proton (an acid) when it’s released, and the build up of protons decreases the pH of the blood. When the body gets more acidic, function becomes compromised because the protons interfere with energy production and muscle contraction.

All this time, athletes have been blaming lactate like it’s a referee. But they should be blaming those protons.

Still, generally, lactate is pretty much always associated with protons, so there is a strong relationship between high lactate and fatigue.

Lactate Threshold: Recycling is the Name of the Game

Blood lactate levels rise gradually as one exercises. The harder the exercise, the higher it climbs; this is an indicator of a shift in our energy production from aerobic (lots of oxygen) to anaerobic (less oxygen).

Before reaching the lactate threshold, blood lactate concentrations increase gradually. But upon arriving at the lactate threshold, the blood concentration of lactate begins to exponentially increase. Usually that intensity hovers around 80% of an athlete’s maximum heart rate, or 75% of their maximum oxygen intake–but you can also link it to speed or power.

Recycling lactate is true north of endurance training, which aims to maintain an intensity below the lactate threshold. When the recycling process can’t keep up, lactate produced by the exercising muscles begins build up in the bloodstream.

Well-designed training programs target both sides of the lactate threshold; there should be some training sessions working at or above LT. These sessions are harder on the body, but this forces adaptations that ultimately increase speed on race day.

Why Does Lactate Build Up Happen During High Intensity Exercise?

Lactate buildup is a result of the rapid anaerobic breakdown of carbohydrate.

Cells break down carbs and fats from our food to produce a molecule called ATP (the body’s energy currency), which is then used as energy by exercising muscles. ATP is produced from carbs through a three-step process: Glycolysis, Krebs Cycle and Electron Transport Chain (ETC). Products from Glycolysis feed Krebs which feeds ETC.

ETC is what generates most of our ATP. Energy generated from ETC is effective enough to sustain moderately-intense exercise...but the process doesn’t happen fast enough to keep up with the energy demand of high-intensity exercise. This means rapid-release energy from glycolysis is required to keep going. Glycolysis increases to supplement the difference but, as we know, this leads to lactate production.


Oxygen delivery rate also becomes limited during high intensity exercise. The ETC absolutely relies on oxygen for its function. We can’t breathe enough, or pump blood fast enough to our muscles when they are in overdrive to keep the ETC going. This necessitates oxygen-free energy production via glycolysis and lactate production.

That extra lactate (along with its acidic proton) ends up in the blood and decreases our pH. Our brains aim to keep a steady state of pH, and sensing this imbalance in pH, cause us feel nauseous. This leads to a feeling of fatigue, then a decrease intensity, then decreasing ATP demand, then glycolysis slows, leading to a better match between oxygen demand and oxygen delivery. Ultimately, this match allows lactate clearance from the blood.

Exercise above the lactate threshold can only be sustained for a limited amount of time: the body runs out of glycogen (stored carbs) to convert into lactate, and the increasing acidity of the blood causes fatigue.

Better athletic performance comes from training with LT in mind, geared to a higher production of speed or power at the lactate threshold.

How to Figure Out Lactate Threshold


Testing protocols to determine lactate threshold are sport-specific. Many consider the running speed at lactate threshold (RSLT) to be the best indicator of running fitness and the most reliable barometer of endurance performance.

In cycling, step-tests (where power is increased at regular intervals until you are exhausted) are the gold standard for measuring physiological performance markers, such as lactate threshold.

Upon completing the test and finding a personal lactate threshold, one can begin incorporating lactate threshold training to target specific adaptations for the body to make.

There are a few different ways to test for a personal lactate threshold, and factors to consider when doing so. It’s important to remember everyone is different, and lactate threshold changes in response to training (or sadly, de-training).

Lab Testing: Accurate But Expensive

The most concrete way to determine lactate threshold is to take a series of blood samples as exercise is conducted at increasing intensities. This type of lactate testing occurs at an exercise physiology laboratory, and tends to be expensive (but worth it).

In a lactate threshold test, athletes exercise on a treadmill or stationary bike while increasing intensity every few minutes until exhaustion. A blood sample is taken during the each stage of the test–similar to testing for ketones, through the fingertip or earlobe–illustrating blood lactate readings at various running speeds or cycling power outputs. Results are then plotted on a curve to show the speed or power at which the lactate threshold occurs.

However, lactate threshold changes as more training is done to build your aerobic base. So in order to maintain an updated understanding of your lactate threshold, you’d have to visit the lab again after a block of training.

During her time on the Great Britian Rowing Team, H.V.M.N. Research lead, Dr Brianna Stubbs, did lactate threshold testing every 2-3 months. She recounts the collective effort to find lactate threshold.

"The gym even got gory on step-test days, with athletes dripping blood from the testing holes in their earlobes."Dr. Brianna Stubbs

"Seeing results change over time was interesting," she said. "I recorded my highest power at lactate threshold toward the end of the winter training block, which made sense because that’s when we did most of our endurance work."

Do-it-Yourself Field Test: You Have a Few Options

Many endurance athletes choose to estimate their lactate threshold by measuring heart rate and/or VO2 max at different training zones (there’s even a portable lactate blood analyzer some use to further cement results).

VDOT (or VO2 max) Chart

  • A VDOT chart is an adjusted VO2 max chart (created by esteemed running coach Jack Daniels) that uses some of your most recent run times (at max effort) to identify training pace that will maintain your lactate threshold. There are two corresponding chats that work together to illustrate max effort and training paces for different distances (we've simplified it above)

  • For example, running at a 7:49 mile pace at max effort corresponds to a VDOT number of 36. That VDOT number illustrates the pace at which training should be done to maintain lactate recycling: 8:55. For a more in-depth analysis of interval training and different distances, refer to these charts here

Conconi Method

  • Using a heart rate monitor set to a five second recording interval

  • Begin running and increase speed every 200 meters until exhaustion. The goal isn’t to maintain a steady state of exercise, instead increasing incrementally to test yourself

  • Plot heart rate against speed; the deflection point in the graph (where your heart rate goes up much more than your speed) roughly corresponds to speed at lactate threshold

Time-Trial Method / 30-Minute Test

  • Research has shown that doing a 30 minute flat out time trial is one of the most accurate ways to find your lactate threshold without using fancy equipment3

  • Start by warming up

  • Then, on a track or treadmill, run for 30 minutes at the fastest sustainable pace. 10 minutes into the run, obtain and note your heart rate. Then, after the final 20 minutes of the test, obtain and note your heart rate again

  • Add your heart rate at the 10-minute mark to heart rate at the 30-minute mark–that's your lactate threshold heart rate. And your average pace for the entire 30-minute test (assuming it was steady) is your lactate threshold pace

Both elite athletes and weekend warriors can benefit from understanding personal lactate threshold to maximize results. However, lactate threshold is impacted by training and changes over time. So keeping regular on these types of tests will indicate an improving lactate threshold through focused training.

Optimizing Lactate Metabolism

Lactic acid gets blamed for muscle soreness, but the production of lactate is an important metabolic process. The idea that lactate is pure waste and leads to fatigue is somewhat outdated. Nevertheless, a higher speed or power at lactate threshold is still one of the key goals of aerobic training.1

Different strategies can help minimize lactate buildup during exercise.

Warming Up: As Important as Cooling Down

Warming up is important to reducing risk for injury and minimizing potential lactate buildup. During a warm-up, heart rate increases, and blood vessels dilate, meaning there is more blood flow and more oxygen reaching your muscles.

When exercise intensity picks up the pace, there’s less mismatch between oxygen needs of the muscles and blood. Therefore, you don’t need to do as much anaerobic respiration, and you don’t build lactate early in the run.

Equally, cooling down and stretching immediately after a workout is especially important. Gentle exercise (slow jogging or spinning on a bike) or using a foam roller can help clear lactic acid buildup from the muscle by stimulating blood flow and encouraging lymphatic drainage.

Nutrition and Supplements: Replenishment is Key

The key to dealing with high lactate production is dealing with the acid associated with it (that pesky little proton). Two “buffer supplements,” sodium bicarbonate and beta-alanine, work by mopping up that proton. This means lactate levels can go higher than before without triggering fatigue because the proton is taken care of.

Beta-alanine works inside the muscles to clean up protons before they affect muscle contraction. Compounding effects of beta-alanine powder (~5g per day) happen after several weeks, but studies show around a 2-3% performance boost.4

Sodium bicarbonate is better for short-term boosts in proton buffering. Bicarbonate is the main buffer usually binding protons to stop blood from becoming too acidic. About an hour before exercise, taking bicarb powder dissolved in water, at 0.3kg per body weight, has shown to improve performance.5 Be weary of stomach aches when first introducing bicarb. But there are bicarbonate gels that provide the same buffing effect without the side-effects.6

Lactate can only be produced by breaking down carbs. Sustaining an exercise intensity that is producing lactate means the depletion carbohydrate stores (glycogen). When the glycogen gas tank reads empty, we hit a wall.

Exogenous ketones can lower lactate production. By drinking pre-workout exogenous ketones, like H.V.M.N. Ketone, your body can use the ketones for energy instead of carbohydrates–glycolysis decreases and therefore, so does lactate production.

Having ketones as a whole new source of fuel means the body doesn’t need to dip into its existing carb and protein stores: athletes using H.V.M.N. Ketone show a decrease in the breakdown of intramuscular glycogen and protein during exercise, compared to carbohydrates alone.7

Exercise: Training Toward Adaptation

Regular training forces the body to adapt; what once felt like an unsustainable pace becomes easy. And adopting a training plan helps accelerate how that adaption will progress.

Looking at the whole body, the heart muscle gets stronger, building more small blood vessels. These small blood vessels mean more oxygen-rich blood can be transported to the muscles, requiring less demand for anaerobic respiration and lactate production.

On a muscular level, cells can produce more mitochondria, which are the site of aerobic respiration. This helps increase reliance on that energy system. Muscle cells also express more of the transport proteins for lactate, so lactate doesn’t build up inside the cells and compromise their function.8

Lactate threshold training switches up workout intensity, optimizing the body’s lactate response.

Peter Broomhall, who has been running ultramarathons for seven years, started incorporating lactate training into his regimen with his coach.

"I’ve trained with lactate threshold in mind this year more than any other year. It takes time to build up that threshold, but things like recovery become quicker. It compliments every aspect of training."Peter Broomhall

For runners, one way to work on lactate threshold is to breakdown a run into mile sections: the first mile or two should be run at a pace just below lactate threshold, while the proceeding mile section should be slower, thus allowing the body to process the lactate. Active recovery is more effective at clearing lactate than passive recovery.9 This allows a high volume of miles without going overboard.

Lactate, A Misunderstood Villain

Next time your running club gangs up on lactic acid, maybe you can remind everyone of its important role in helping our bodies produce energy quickly when oxygen is short.

We do know the combination of high lactate (and the associated increase in protons in the muscles and blood) can impact our ability to maintain peak athletic performance. But we now have a deeper understanding of blood lactate (and how to optimize it), thanks to monitoring tools outside the lab, structural training regimens and recovery techniques.

We’re altering how the body responds to lactate with nutrition supplements like H.V.M.N. Ketone and bicarb gels. And in the process, we’re rewriting the old story about lactic acid.

Triathlon Training Strategies to Conquer Your Race

Originally posted on HVMN and authored by Brady Holmer on May 16, 2019

A triathlon can be daunting. The three distance races of swim, bike, and run utilize different energy systems and muscle activation patterns. Each requires unique physical and mental skills to reach the finish line.

Triathlon training is also about tradeoffs.1

Jumping in

It would be nice if bike fitness easily translated into the water, or running ability made you a great bike rider. In some ways, fitness does translate. But each discipline requires dedication. A proper training schedule should be specific to triathlon demands.

A triathlon training plan focusing on specificity of the swim, bike, run, and all transition areas will optimize race day performance. And don’t forget about nutrition and sleep; these are considered the fourth triathlon disciplines. Both in and out of season, make sure you hit all of the basics.

Training for a Tri isn’t Negotiable

Finding new challenges and setting goals helps push performance limits. If you’re an athlete who has traditionally stuck to one sport, training for your first triathlon may be just what you need to spice up your training schedule. It may also light a new competitive flame.

Triathlon training can stimulate your body in new ways and work new energy systems. It’s like rigorous cross training. Triathlon-specific fitness can improve overall health, may translate to reduced injury in other sports and perhaps weight loss, if that’s a goal.

Triathlon 101: the Various Triathlon Distances

Before developing a training schedule, the first step is to decide which triathlon distance you’ll conquer for your next or first triathlon. This will influence your workouts and overall training time.

Sprint Distance Triathlon

Swim - 750 meters (¾ mile)

Bike - 20k (12.4 miles)

Run - 5k (3.1 miles)

Standard or Olympic Distance Triathlon

Swim - 1.5k (.93 miles)

Bike - 40k (24.8 miles)

Run - 10k (6.2 miles)

Half-Ironman

Swim - 1.9k (1.2 miles)

Bike - 90k (55.9 miles)

Run - 21.9k (13.6 miles)

Ironman Triathlon

Swim - 3.9k (2.4 miles)

Bike - 180k (112 miles)

Run - 42k (26.2 miles)

Which Distance is Right for You?

There are a few things to consider when choosing your race distance.

The first: time. How much of your schedule can you dedicate to training? Most programs include two workouts per day, several days per week. You’ll likely need to dedicate 10 - 12 hours or more to training each week. Naturally, a longer race (half-Ironman or full Ironman) will require more time in the pool, on your road bike, or laced into your running shoes pounding pavement. Most people don’t have the luxury of being a pro-athlete with unlimited training time. The average Joe isn’t training for the Ironman World Championships in Hawaii.

Training environment is another consideration. Will you be able to practice open water swims in a nearby lake, or is a pool your only option? Trails and roadways conducive to long runs and rides may dictate training quality and safety.

The most obvious consideration is experience.

Many new triathletes want to attack the biggest race their first time out, but this could spell disaster.

A long history of athletics or endurance sport may allow you to seamlessly finish your first race without much trouble, but it may not. It’s important to learn to enjoy the journey of the sport as much as the destination.

Dividing the Training Pie

You have three sports to train for, and only so many hours. How much should you dedicate to training for each discipline? Tradeoffs dictate that, by choosing to spend more time in one activity, you must lower the amount of time spent in another. Swimming, biking, and running can be thought of as three slices of the giant training pie.

The relationship between triathlon training and performance is specific.2Time spent training in a specific discipline directly predicts performance in that race leg. More swim training means a stronger swim portion. This makes sense physiologically because the same muscles, motions, and pace we train are the same muscles, motions, and pace with which we compete.

Generally, you should do the same number of swims, bike rides, and runs each week. In total, aim for two workouts per week for each discipline. An easy formula for this plan follows a single swim-bike-run-swim-bike-run each day. This also includes one day per week to be used for recovery.

While on the topic of rest, plan your training program so you never have back-to-back hard workouts (e.g. interval training on Monday and a hill workout on Tuesday).

If you’ve assessed your strengths and determined you may need a little more swim, run, or bike work, an additional third session of a specific discipline can be added per week. This might come in the form of a “brick workout” (discussed later) or a day where you complete two workouts (a double).

Volume and Intensity

Early research on elite endurance athletes found they gained the most fitness when completing approximately 80% or more of their training at low intensity (below lactate threshold) and the remaining 20% at moderate or high intensity.3 This pattern was remarkably consistent. A high-volume, low-intensity training program, sprinkled with high-intensity intervals sessions, can produce success in longer endurance events. Do what the elites do and you might snag an age group or podium finish.

Applying this rule to your training is simple. Create a schedule where 80% of your training volume (in time) is at a low intensity. What is a low intensity, exactly? Generally, low intensity is regarded as anywhere between 45% - 80% of your predicted heart rate max.

Plan your remaining training sessions at moderate or high intensity. These will be your interval workouts, tempo sessions, and hill work. One high-intensity swim, bike ride, and run per week is the general framework. High-intensity training occurs at a heart rate from 80% - 100% of your predicted heart rate max.

Cornerstone Workouts

Spending time logging miles in each discipline is crucial to develop proper endurance needed for the triathlon. Practice swimming, biking, and running at paces and tempos you’ll experience on race day.

It may be useful to research the race course to determine layout and elevation changes. Find out whether you’ll be racing an open water or ocean swim. This can help to guide specific training sessions.

Swim–Technique Sets

The swim portion is the most physically-technical part of the triathlon.

Good swimming should look almost effortless and relaxed. Swimming better isn’t just a matter of moving your arms harder or faster–efficiency is important.

You can build efficiency in two ways. The first involves swimming a set distance (say 25m) with a lower number of strokes in the same amount of time. Swim five sets of 25 meters each, and lower your stroke count by 1 - 2 for each repetition. This will improve the distance you can travel with each stroke.

To improve tempo, swim a set distance in the same amount of strokes, but decrease time on each repetition. This means you’ll be taking strokes more frequently.

Focus on long, clean strokes rather than choppy harsh ones.

Other Swim Training Tips

  • If your race is open water, be sure that you practice a few open water swims before race day. Your local pool won’t mimic an ocean swim

  • Practice sighting: swimming off course or getting lost during an open water swim can spell disaster for your race. Sighting is the ability to pick your head up enough while swimming to ensure you’re heading in a straight line to the buoy or other landmark. You can practice this in the pool

  • Find a triathlon coach or join a team. Since swimming is so technical, learning from someone more experienced may have benefits

  • Go the distance: it’s recommended to practice swimming the complete distance you’ll be racing

  • Purchase and practice getting out of your bathing suit and swim cap. You don’t want to lose valuable race time struggling with this

Bike–Hill Sessions

The bike discipline of the triathlon is where you’ll spend the most amount of race time, and is also where you can potentially make up the most ground lost. Cycle training is crucial because many triathletes underperform on the run due to residual fatigue during the bike.

Power is the cyclist’s most crucial asset. More power on your road bike means you can ride faster over any race distance. Workouts to build power should be included in your cycling plan, and hill sessions are a great way to increase power. Hill workouts become extremely important if your race course contains significant elevation changes, long climbs, and steep inclines.

To hill train, start by finding a hill with about 1,000 feet of climbing. Each week, try to increase the distance climbed on this route while maintaining the same cadence and effort. If you have a power meter, trying to maintain power on climbs while increasing distance is a way to gauge fitness improvements.

Another variation of hill sessions are high-intensity uphill sprints. Sprint uphill for 60 - 90 seconds, followed by a ride back down for recovery. Repeat this 8 -12 times per workout.

Bike–Lactate Threshold Work

Your lactate threshold is the highest intensity you can sustain for around 60 minutes. At or above this intensity, the body starts to accumulate lactate, signaling a reliance on anaerobic energy production systems.

Exercise above this threshold can’t be sustained for long, so working to increase your threshold is crucial.

Lactate threshold is the best predictor of race performance for many cycling events.4

LT workouts are typically done as longer intervals. Find a long flat road where you won’t have to slow down or stop often. Try doing 3 - 4 ten-minute intervals at your lactate threshold pace. Increase time as you progressively get fitter or add more intervals.

Other Bike Training Tips

Unlike swimming and running, biking involves more technical equipment. Consider a few of training tips help optimize your time in the saddle.

  • Learn to change a flat: nothing ruins a great bike ride like a flat tire. Even worse, this could happen during your big race. Invest in a patch kit and a spare tube just in case disaster strikes while out on the road

  • Get fitted: a proper bike fit is critical to maximize comfort and efficiency in the saddle, and even boosts performance by increasing power and optimizing aerodynamics

  • Consider indoor training: any bike can be hooked up to an indoor trainer. This will prevent days lost due to training if you can’t make it outdoors

Run–the Long Run

Endurance runs form the base of triathlon run training; they're key to developing a powerful heart, increasing muscle capillaries for oxygen delivery, building robust mitochondria, and strengthening running-specific muscles.5

Long runs build fatigue resistance and confidence, both crucial to perform well on race day. A general recommendation for triathletes: long runs should equate to about 35% of your total weekly running volume. If you train 4 - 6 hours per week, this would mean a long run of 1.5 - 2 hours or more.

Run–Speed Work

Speed (interval) training allows you become better at running faster, with goals of increasing lactate threshold and improving V02 max.

High-intensity speed work should occur at 80% - 100% of your maximal HR or V02 max.

Generally, a 2:1 or 1:1 work to rest ratio for intervals is recommended. This might take the form of two minutes at high intensity followed by one minute jog recovery, repeated eight times. Feel free to experiment with different types of intervals and mold them to your race distance.

The Brick: Your Best Friend and Worst Enemy

The triathlon is not three separate sports, but a single sport combining three interconnected events. The back-to-back-to-back nature of triathlons means you’ll need to practice the transitions and simulate the fatigue you’ll experience on race day. Brick workouts are race day dress rehearsals.

The brick is a specialized workout typically combining either a swim/bike or a bike/run into a single session.

In each, the first activity is followed immediately by the next with little to no recovery time.

Brick workouts allow the body to adapt to specifics of swim/bike and bike/run transitions. There are biomechanical and physiological differences among all events that will make transitioning uncomfortable if not practiced. Brick sessions allow you to practice making seamless transitions and minimize your performance drop from one event to the next.

Sample Brick Workouts

A simple brick workout might include a 500 meter swim in a pool, followed immediately by an easy bike ride of around 45 - 60 minutes. As you adapt to the transition, you can increase length and intensity of the swim and the bike ride.

For a bike/run brick workout, the same format can be applied. A 45 - 60-minute bike ride followed by a 30-minute run can get you into the rhythm of using different muscles and movements during this transition.

Outside of brick workouts, practice your swim-to-bike and bike-to-run transitions. Rehearse getting out of your wetsuit and swim cap, getting onto the bike and then, unclipping your cycling shoes and lacing up your running shoes. This will make sure things go as smooth as possible on race day.

When to Brick, and How Long to Go

Most triathletes should aim to complete one brick workout every 3 - 4 weeks. Keep the intensity of the swim, bike, and run the same as that of other workouts. If you had a moderate intensity swim or bike planned for a particular day, do a brick workout with both events at moderate intensity.

For duration, if you’re training for a sprint triathlon or Olympic distance triathlon, this workout should be 50% - 100% of race distance. For half-Ironman and full Ironman triathlons, 25% - 50% of race distance is recommended for a brick workout.

Fuel for the Work Required: Triathlon Nutrition

High-volume training means you’ll be tearing through energy stores. This requires you fuel properly and strategically.

Pre-Workout Nutrition

What you eat before a workout plays two roles. The first is ensuring that you’re able to maximize energy production needed for high-quality workouts and attain the greatest training adaptations. The second is the opportunity to practice race day nutrition strategies.

Training Low

The practice of training with reduced fuel availability, termed “training low,” is a recent strategy used by endurance athletes. It involves doing 30% - 50% of your training sessions with reduced carbohydrate availability.6 This could be accomplished by doing your ride, run, and swim in the morning after an overnight fast.

Manipulate carbohydrate availability on a session-by-session basis with intensity and duration in mind. Train low sessions should be planned around your lower-intensity workouts.

This is because low-intensity exercise relies more on fat oxidation versus carbohydrate oxidation for energy.

Training in a “fasted” state increases free fatty acid availability and lipid oxidation which can subsequently be used during the session.

There is evidence that training low stimulates post-exercise gene expression, oxidative enzymes, glycogen storage capacity, and other molecules related to positive metabolic adaptations compared to exercising with high carbohydrate availability.6 Multiple studies report exercise performance changes following exercise training with carbohydrate restriction, such as improved time trial and submaximal exercise performance.7,8,9

Train Dual-Fueled

When the body is low on carbohydrates, it burns more fat and even produces ketones for fuel. Ketones are the body’s natural back up, used in an energy crisis to replace carbohydrate–typically you either have enough carbs to get by but no ketones or no carbs and then elevated ketones. It's a trade off between fuels.

Not so with H.V.M.N. Ketone. After consuming H.V.M.N. Ketone, the body can use both carbohydrates and ketones for energy, essentially giving the body two fuel tanks to employ. The result? In a 30-minute time trial, elite cyclists rode 400m further (performing 2% - 3% better) after drinking H.V.M.N. Ketone.10

Have Sufficient Fuel for High Intensity Sessions

High-intensity sessions rely more heavily on carbohydrate oxidation than low-intensity work. For these workouts, having high availability of carbohydrate is recommended in order to maximize training output and adaptation. Pre-exercise carbohydrate intake (3 - 4 hours before a workout) enhances carbohydrate availability during exercise and has been shown to improve endurance capacity.11

Jumping in

A triathlon training plan doesn’t have to be complex. After you’ve found the right race, following some well known strategies in regards to your training and nutrition will set you up for success at any race distance.

Peak Carnivore: The Ironman Champ Who Only Eats Meat ft. Pete Jacobs

Originally posted on HVMN and authored by Zhill Olonan and Geoffrey Woo on June 27th, 2019

In the world of sports nutrition, a constantly evolving field, more and more athletes are adopting low-carbohydrate diets. Especially in the case of long distance endurance racing, an aerobic-heavy activity, wouldn't it make sense that athletes could benefit from being fueled by fat vs. carbohydrates?

This is a popular debate with conflicting evidence and anecdotes presented from both sides. In this podcast, we capture the personal story from a former Ironman Champion: Pete Jacobs. He's not a carbohydrate athlete, nor a traditionally ketogenic one...Pete is purely fueled by meat.

Pete has faced a life-long battle with his personal health. Ever since he found it nearly impossible to get his heart rate up during high school sports, along with rough bouts of fatigue and gut issues, he knew he was facing an uphill battle. Although he marched on to successfully pursue a sporting career, Pete has struggled in the health department as he pushed his bodily limits in the performance department.

With intuition that the core root cause was linked to his metabolic health, Pete gave the ketogenic diet a spin. He saw notable progress, but eventually found his nutritional calling to be one (or two) steps further...

The carnivore diet.

In this episode, you'll discover:

  • Why the carnivore diet worked for Pete and what health issues were corrected

  • What Pete eats: Organ meats, seasons with salt but no pepper, what animals he's tried, and more

  • Tips for endurance performance: Using ketone esters & caffeine, the power of positive mental reinforcement, and applying endurance ideals to normal life

Geoff

Pete, thank you so much for coming on to the H.V.M.N. Podcast. It's really an honor to have you on the program.

Pete J.

I'm excited to be on. Great to meet you.

Geoff

For folks that don't know your full background, 2012 World Champion in the Ironman. Obviously, the top of the top and in that universe, but also a pretty interesting story around diet and nutrition, obviously, at the performance level, you're dialing in for performance, but it sounds like you got into some of the nutritional and physiology side of things from solving a personal problem with health. So, perhaps to start off the conversation, curious to hear about your interest in diet, nutrition, health, and then probably as a segue or maybe a parallel question, how did you get into endurance events or triathlons?

Pete J.

I guess my interest in what's going on in the body was when I was a teenager and I started getting a bit of fatigue, I just would not be able to get my heart rate up. And I was always a good swimmer, did surf lifesaving competition, so I was always swim training. And some days, I just could not push my heart right on my body at all. So that was the beginning of getting tests done. And fast forward through till I was about 30 years old and I'd had a lot of ups and downs and fatigue issues during my racing career so I became a professional triathlete when I was around 21 years old or so. And if I felt good on the day, I would smash it and I could win races and show a lot of promise. But if just body was not responding on the day, I would just dig myself into a hole and then that hole would last for a day or a week. And then I managed that basically progression through till when I was 31, I won the Hawaii Ironman. And in my training, I would have had days where I didn't feel great, but I'd learned to manage it and I'd learned that my weakness was I couldn't do as much as other people. But that also became my focus of my strength.

Geoff

So you were streaky. So there's some really on days and some really off days, it wasn't just like low energy overall, because I can imagine that if you were just always low energy, you wouldn't realize you had a talent for endurance events, right? So you were very streaky it sounds like?

Pete J.

Absolutely. And then some days, I could go from feeling terrible the day before and not being able to get my heart rate up to just jumping on the bike or running or swimming and feeling amazing the next day. And so, yeah, it was pretty tough, but I'd learned a lot of things about controlling ego and not worrying about missing a session when I felt a bit tired. And that's partly what got me to such great shape in 2012. I would have had days where I trained quite poorly but I was happy, I was like, no, this is the best that I can do, I don't need to do as much as everyone else, and just focused on as much as I could do without any ego or guilt and turned that weakness into a strength. I was able to get there and winning in 2012. And then after 2012, obviously I was a bit older, I'd done by then about 30 something Ironman races, and a lot of them not when I was that well. Like I said, just fatigue, there was not a lot of other symptoms other than, excuse me, I developed some psoriasis in my 20s, which is, now I know it's directly linked to leaky gut issues.

Geoff

And usually associate with alcoholism, right? I presume you weren't binge drinking for your psoriasis.

Pete J.

No, no. Now I don't drink at all. I might have one drink once a year sort of thing. But after winning, that fatigue went from a day or a week to a month or two months. And the muscle weaknesses then got a bit worse. So I would have more imbalances that sort of appeared to be sort of just someone would say it's injury or it's weakness or this or that, but it would always come around the time when I was also feeling fatigued. So I'd push through as best I could, got in good shape again for a race every now and then and I kept trying to go back to Hawaii for a few years in a row trying to, after winning, I kept going back to try and do it again, but just couldn't get my body in shape because I couldn't string together more than about six weeks of training. And in six weeks, I could get quite fit and be like, yup, I can still do this, I've still got it. And then I would just fall in a hole for a month or two.

It became a pattern of chasing the answers to my health and also then a period of fatigue. When I was fatigued, like it was brain fog, it's aches and pains, it's depression, just there's no joy in it anything. And it became, I would be okay, let's work this out and I'll figure it out and I'll change something and I'll get better and I'll do testing and I'll change diet. When I'm fatigued, there's nothing that I feel like doing. There were times when Jamie was the one that was really my wife, Jamie, she would, okay, let's get to another doctor, let's try and find someone else. And I just, you know, when I'm fatigued, it's like, I don't care, I just want to lay in bed and I'd have no motivation to try and figure it out.

Geoff

That's a good question. I mean, I'm sure you're as you're talking to all these doctors, different experts, did they ever diagnose you? You sound like you were puzzling through a lot of these doctors and they weren't necessarily able to perhaps help you.

Pete J.

Yeah, no, I've never been diagnosed with anything until recently, the leaky gut is a prime problem definitely. But I've been to a lot of people, done a lot of stool tests since I was 16, 17, all the sorts of hair, urine analysis, everything, you know, lots and lots of dollars worth over about 20 years because I'm now 37. No results ever. I've tried a lot of therapies and some worked somewhat and definitely kept me going. Oh, okay, I'm improving, I can get back into the career again. But then it would be a bit of a false lead where I would feel better for a little while but then I would just reform back into the same old patterns. And so yeah, things eventually came around to diet a few years ago, and I started working with Phil Maffetone. And he's brilliant around health and performance, very holistic approach. And I started cutting out grains and sugars and really getting my diet much better. And again, I saw improvements each time I change something but nothing that really, really stuck.

So, it was in 2000, end of 2017 where I raced again and I just had terrible, terrible feelings in the rice. And I said, okay, I cannot race again until I'm 100% sure that I've gotten like an answer that is going to improve my health. So, I took all of 2018 completely off. And for the first part, I was still feeling very, very achy and fatigued even without training, and finally sort of started seeing a couple of doctors that started giving me a bit more information. And then finally I got into really low carb, and Low Carb Down Under has been a fantastic resource with all the conferences that they've had and all the videos that they post. I've learned so much from that. And I was able to get in contact with Dr. Paul Mason, who's got some amazing videos on their websites for Low Carb Down Under. And being an Aussie and interested in sports as well, he's been able to lead me towards the carnivore lifestyle, and I was already getting it a little bit in about August last year when I had the year off.

I listened to some podcasts and one of them mentioned low fiber can be good for people with irritable bowel syndrome issues. And another one that said that high protein, you won't get out of ketosis or it's not going to raise your blood sugars because I got into ketosis years ago, probably three years ago or so. All the things back then was don't eat protein and fasting and these other things that aren't good for me metabolically. I shied away from protein, ate a lot, a lot of fat. I was feeling better but again it stalled. And then I sort of started to revert back a little bit. And I definitely didn't lose weight and trim up like people say you should on keto. So when I was able to talk to Paul Mason earlier this year, he said, just go 100% keto. So I'd been feeling better with more protein less fiber. And then he said, now just 100%-

Geoff

Carnivore.

Pete J.

Yeah, but then I was only on about coconut cream, cacao powder, coffee. I'd already minimized all my plant inputs but as you would have heard many anecdotes of, that some people just need to be 100% off certain foods to feel better. For me, it's 100% because even now, you know, I'm 99.9% carnivore, but if I have a supplement that has a little bit of something in it or a mouthful of something that isn't 100% plants, then I get a little bit of my psoriasis back, little bit of redness on my face back and dry skin. And it's a direct link to leaky gut. So I just have this really great autoimmune reaction, even though I've never been diagnosed with autoimmune issue or a certain disease. I still have this great reaction, and my mom has a couple of autoimmune conditions. So, there's something genetic there as well.

Geoff

So how long have you been 99.99% carnivore? So this has been four or five months now?

Pete J.

Yeah, yeah, four or five months, but I was still trickling in a little coffee here and there like just decaf because I don't believe that the caffeine is good for me with some other symptoms that I've had with over brain stimulation and that kind of thing. I'd always shied away from caffeine the last six months but I was still giving in I guess, it is that just giving into something, I'd go, maybe it's still okay for me. So I would taste it and then I would get some symptoms back. So, I really do have to be 100%, and that's been yeah three or four months of just fish, meat and eggs. And you know, I'm quite happy with that and I'm experimenting with different ways of cooking meat and aging meats and adding different meats to meet.

Geoff

Or eating organ gut meat, I mean, I know there's like a nose to tail version of carnivore where you try to have not just ribeyes and muscle meat, but you try to have the liver, the kidney, the heart, the gelatin. All of it are or how deep have you gone into this territory?

Pete J.

I eat liver every week or two. And then just in terms of trying to still be creative and taste different foods when it's quite limited, I've tried lambs brains. I eat heart fairly regularly actually, lambs heart, ox heart. Partly because it's the cheaper cuts but they're still quite tasty to me. I can't afford ribeyes and my career had a a year off and I'm still on the comeback trail. So, ribeyes would be lovely for every meal but I definitely can't afford the prices they have here. So I eat those, I eat a bit of game meat, kangaroo meats. What else do I do? I have a little bit of bacon. I hadn't had bacon or pork for quite a while, but as I said, chucking in just a little bit into my slow cooker as I'm using the slow cooker a lot, those extra depth of flavor really, really matter. So it's just salt.

Geoff

And then for seasoning, just salt?

Pete J.

Just salt and bacon is my seasoning. And eggs.

Geoff

Definitely I've heard a lot of people that are going that way. I think there's concerns around black pepper, for example, very popular seasoning, but there are people are concerned with the oxalate content to have an anti-nutrient within pepper. I think this is an entire fascinating space because I think for myself, I've experimented with the carnivore diet but I don't have the reactions of having pepper or vegetables or grains. Unfortunately, and I think most people don't have those harsh reactions to a more classical diet. But absolutely, it sounds like for folks like yourself and we had Mikhaila Peterson on who's a fairly prominent vocal carnivore who talks about having a little bit of pepper will throw her off and there's clearly something going on with autoimmune, leaky gut sort of access that people have been talking about.

Pete J.

And when you're adding the stress of training on top of that and any other stresses in life that affects vagal tone, which is another thing I've worked on to try and get the gut to be more relaxed and accept more things, it's hard when you, yeah, maybe I could tolerate more in the future if I really was like a monk and totally relaxed all the time. Maybe it would improve over time. But as long as I'm still training, I think I'm going to have that heightened sensitivity.

Geoff

Clearly, there's likely some genetic component to having a predilection for autoimmune issues. But I also imagine that if you're doing heavy endurance training and you're fueling in an Ironman, you're probably slamming a ton of carb goo shots, all this stuff, and that's not necessarily good for leaky gut. I'm curious, this is speculation, but curious where you think that it was kind of genetic predisposition that you were a little bit unlucky to have a likelihood for autoimmune or leaky gut issues versus how much did your career as a professional athlete push you further down that line because you were using your body so hard.

Pete J.

I think it's a combination of both, you know, environment and the genetic factors as well. So I got some pretty bad gut issues in my early 20s, like in terms of a virus that hung around for a month or two. And then years later, I was getting tested and had Blastocystis hominis. So antibiotics throughout this time every now and then, as well as taking all the sugary supplements, as well as training very hard and doing hard races. And that blastocyst, then at some point, I got anybody under anesthesia to be placed directly on the side of the blasto. So I had this really powerful antibiotic placed in me. And that didn't even get rid of it but I did feel terrible for a couple of months.

And so, I have a lot of antibiotics, a lot of sugars, and a lot of gut bugs that shouldn't be there over the course of about 10 years or so. And I would always have bad gut symptoms, and I'd try and do what I could to mask them while training so I wasn't stopping on the toilet every every few minutes while going for a run. That hung around for quite a long time. And again, a lot of stool tests, a lot of different people trying to fix it to no avail. But eventually, now, my guts are absolutely great. I feel they're the best they've ever been with the no fiber, high meat diet.

Geoff

Yeah. Which is wild because likely when you were coming up in your career, the dogma or the practical advice was completely the opposite, right? A lot of fiber and carb load like crazy, right? When the average person hears about marathons or Ironmans are like carb load, eat a bunch of pasta beforehand. So, I imagine that's what you were doing. You were focused heavily on carbs and then fueling with all this sugar bombs as you're competing. It sounds pretty amazing that you were able to do well even with your guts, like, you know, I guess blowing out every now and then. I mean, do you have stories where you're competing in a race and you just need to, you know, you have diarrhea? I'm likely sure that you do have some of those stories, I'm just curious, I mean, how bad did it actually get?

Pete J.

It was probably about 2009 or so when during the marathon in Hawaii, I'd run into the top 10, I was having a really good run and I could see the next guys just in front of me, I was gaining on them. But then I suddenly had to stop in a porta loo, take a quick little break, and then get back running. And I could never bridge back up to those guys in front of me again. And another Australian world champion, Chris McCormick said to me after the race, "Mate, that was the most expensive shit I've ever seen anyone take." He felt like having to stop at a loo probably lost me a few places. And I think I finished about ninth that year. So that's one.

But then the following year it was quite tough. I was always having to stop a few times before I could get out the door. But I ended up finishing second that year. But after finishing second, it was like, right, what do I need to do to win and I just stepped up my game big time, mindset and what I was doing, all the boxes I needed to tick. And so, I just was able to take a few supplements, you know, sort of slippery elm and other intestinal helpful supplements. And that year leading into Hawaii, I actually didn't have any gut symptoms for the last couple of months. So, doing a bit extra helped. And obviously, it helped me trying to get better and get the win that year.

Geoff

Incredible. So basically, you had enough of a stable gut to push enough months where you had a clean race and you were world champion that year. And now it's been a struggle to get your body back into that shape where you're not having to go to the bathroom every few hours.

Pete J.

The bathroom thing probably subsided a little bit again because I wasn't even training that hard for that long. It was about five years of trying to get back there without any really good training going on. I just kept trying different things but I'd always eaten pretty healthy. And I think that kept me or helped me win, that I was eating pretty much the same meals regularly. My regular meal was brown rice, some beans and tuna, lots of oil, and maybe a few nuts. But it's not necessarily a great meal for anyone that's got some issues. But, for some reason, it worked because I was eating the same very similar ingredients day in and day out. So that may have had some help that my body just got used to those particular foods and I was able to get through okay.

Geoff

And then when you were shifting more into this low carb lifestyle, were you measuring your blood glucose or hemoglobin? I know a lot of our listeners who are either in keto or eating low carb or exploring it, a lot of folks like to measure and compare stats and all of this. How metrics driven were you with potentially wearing a continuous glucose monitor, were you measuring ketones or was this more intuitive and you were just trying to feel how you're performing?

Pete J.

Yeah, when I first got into it, I didn't really get a lot of blood tests done. Phil Maffetone was just trying to guide me through some of these changes and saying, look, some people are going to feel much better in ketosis on a keto diet. And he did have a strong suspicion that I was, I did have some metabolic syndrome issues. And so, then I did buy a glucometer and started testing, and it was really, really unstable. And that was frustrating, that my blood glucose in the morning would be high and sometimes it would be low. And it was just all over the place. So yeah, very erratic blood glucose for probably a good year and a half or more maybe before I started to see some consistent numbers and it starting to settle down.

And ketones were always low ever since I first did ketosis. It's like .2 is as good as I'll get day to day. Which, chatting with Dr. Paul Mason about the mechanisms there, like, we're both really interested to know exactly what would be going on that, you know, are you using because you're more metabolically efficient or you're not producing enough as as much because you're metabolically efficient? So is it like you're not producing more than you need or you're using it very quickly? A few unanswered questions. But eventually, blood glucose improved as I was more and more on a low carb diet over another year or so. And then ketones, if I would drink MCT oil, basically, I could get ketones up. So there was a period where I was trying to chase ketones. And again, back a couple of years ago when everyone was like do this, do this, don't do that. And since then, I'm aware that MCT oil can be bad for leaky gut and cause issues. Stay clear of that now.

Geoff

Yeah, I've had personal experience where you have a little bit too much and your gut wants to go. I mean, I think that's the fine line with MCT. Obviously useful for its use cases, but a little bit too much, you get diarrhea pants.

Pete J.

Yeah. By that point, I could handle a lot of, quite a bit of fat. But there'd still be times where it's like you have too much fat. And then, I guess as I've increased protein, I've seen it really stabilize. I've seen no drop in ketones. They're still always the same, about .2, except after exercising, a longer low intensity training session.

Geoff

And they'll pick up.

Pete J.

Yeah. So, I've done some good testing lately and I did wear a continuous glucose monitor a couple of months ago for two weeks. And yeah, that was quite interesting just to see what was going on throughout the days. But by that point, it was quite stable. My blood glucose is really stable nowadays. But I did notice a few things such as high intensity training, my blood glucose would go up. So, I was getting a release of glucose from somewhere because I would do these without taking on any carbs or sugars whenever I could. And the next day, it would be higher, a little bit higher all day. And again, I asked Paul about this and he said, it generally it's okay if it's a little bit higher. It's just that the fluctuations of insulin that you want to avoid. If it's stable and the numbers are a bit different, that's fine. It is more the insulin fluctuations you don't want.

Geoff

I mean, glucose is a downstream effect of insulin. It is interesting in terms of reflecting in our experience in my personal experience, yeah, when you're doing heavy and intense exercise, it makes sense that your blood glucose elevates because your glycogen is being released, you're actually using that as fuel.

Pete J.

And stress response from cortisol.

Geoff

Exactly. So it stands to reason. One thing that I was curious to hear about and I think you'd be a good person to ask here is that a lot of people when they talk about shifting into a keto diet or a low carb diet, there's a keto adaptation period where you're going from heavy carbohydrate metabolism into more of a fat dominant metabolism. They feel like that takes a while to shift and maintain performance. So a lot of people feel like a keto flu or any of that. And obviously, you are performing at a very, very high level. Did you feel like you've lost performance in that transition period or did you very quickly transition into being predominantly fat fueled?

Pete J.

It's probably hard to say exactly what I felt because I was having-

Geoff

You were just kind of sick the whole time?

Pete J.

I was still having some health issues at the time. But looking back and if I was saying what other issues are going on, there's so many factors that change when someone crosses over. So yes, there's definitely changes in the mitochondria that they can become better at up-taking ketones and burning fat for fuel. But at the same time, I think it takes a while for people to figure out the nutrition that they need. So like, for me, for example, I'm feeling much better eating higher protein. And I think a lot of people that go into the keto diet perhaps in that first couple of weeks, they are just not eating enough. So they probably have gone low protein because this whole perception, and perception is an amazing thing. You think, oh, that steak that I used to eat, that 200 grams steak, now it needs, you need to eat twice as much of that now, even more than twice.

And so, there's definitely going to be some changes in people's perception that need to occur before they can really dial in their diet. So eating more meat, and obviously the salts and getting used to that change as well, a lot of people have issues with. And then I don't feel like it's so much do with the training, I have seen other people who sort of coach in the low carb area go, oh, well, we need to do high intensity efforts to try and keep you have a high end, to try and keep your legs fast. And it's like, well, that doesn't really make sense because there's nothing really changing in your energy production. It's still just energy. It's just a matter of where is coming from.

So as you said, if you do high intensity efforts, you're going to have a good level of blood sugar anyway. So I don't feel that whether you do high intensity efforts or not or whether you, I think it's more of where you're at in your health and other health issues, like whether it is the calories or whether it is that you're training the wrong type of training in the first place, whether you're just training too hard. But definitely, you would probably want to have a period where you just have a bit more aerobic training perhaps in that transition phase because perhaps you can, in too much high intensity, you will deplete glycogen from your liver or your muscles a bit too much maybe. And that could put strain on your body where your blood sugar's low. After a hard session, your blood sugar could probably drop. And you are just going to feel tired.

But that's where, we might as well mention the Ketone Ester. Ketone Ester, because I've been experimenting with that a bit, and being fully keto adapted. But as I've said, my ketones are generally kind of pretty low and my blood sugar's really stable, but generally a little on the low side as well and I don't even notice that it's in the low fours, I won't even notice. But when I go out for a long aerobic ride nowadays, for example, and keeping my heart rate quite moderate, there can be a little bit lull between the dropping blood sugar that goes quite low and the increase in my ketones that I then find at the end of the session. And I think that's just similar to when people are changing out the diet. You're just getting used to having that lower blood sugar and then when the ketones pick up a little bit. And I think that's all it is, it's just a brain fuel.

So for a lot of people, it's just the perception of effort. So, the ketone drink could be used in that period of adjustment between not using blood sugar as predominantly and also increasing your ketones just like in, you know, so you might need it over a couple of weeks or you can just use it in a particular session as well to get over that little hump. And as I said, I don't do coffee. So, that's something else that can replace that need for caffeine, that need for that stimulation, that perception of how hard is this effort. And I had a friend say that he was feeling a little bit flat on a bike ride the other day. He stopped, he had a hamburger, chilled out, I think he probably had a coffee as well. And then he felt much better after that stop. And it was sort of like, well, was that the blood sugars or was that this or whatever? And I was like, it's probably just because you felt happy. You had a break, your body got a little bit of a rest so it probably just built up a bit of extra energy in storage. Like maybe it was the chemicals that are helping produce your ATP and everything just got a little break. And you're happy, you had a hamburger, you relaxed, you felt like hey, I'm on the way home now. I haven't got as long to ride. So there's all these different factors of mindset that play into how your body is feeling and working.

Geoff

I think that's interesting. I think you're touching on some of the new aspects of our ketone ester that I think are particularly interesting. One, obviously, the fuel partitioning, we think that one of the main benefits is that you're just having an additional fuel that helps you transition between these states. I think one of the points that you're referencing is, if you aren't fully adapted and you go heavy into anaerobic areas of heart rate and fuel usage, obviously, if you have a limited amount of glycogen stored up because you're eating low carb or keto, that might be a difficult transition state where you lose a little bit of top in power.

So I was curious to ask if you felt like you lost some top in power as you're transitioning, but it sounds like you've been able to manage that transition pretty smoothly. And I imagine that your aerobic threshold is probably very, very high. I mean, most of the super elite endurance athletes I see just have, basically, up until VO2 max are still aerobic until like a little bit over and they just completely dropped. So imagine your VO2 anaerobic aerobic threshold's like very, very high. I'm curios if you actually have done that study to see exactly where that turnover point is. But I think the Ketone Ester use is like still very, very, very new. I mean, it's been out for a year, year and a half. But I would say that people are still figuring out exactly how to best utilize it. I mean, it's still like a cutting area of research.

I think one part that you mentioned, the central nervous system, the neurological impact is an exciting area. I think there's some data pending publication around improving content performance and I think part of it is that can you just deliver a little bit of extra fuel into the brain where you feel a bit better, feel a bit sharper. And that might play one of the most interesting roles for boosting performance as opposed to necessarily being a "superior fuel." I mean, I think this is some combination, again, of different factors here because physiology is so complicated. But I thought you hit a couple of different interesting points that I wanted to quickly address. But I guess going back to a specific question, I'm curious, have you looked at your aerobic anaerobic threshold, your VO2, VCO2 turnover point. Because I imagine again, in my experience, your turnover point is probably super, super high. I mean, you can go aerobic almost indefinitely.

Pete J.

Yeah, it's on the cards for July, August sort of thing. Really just want to get a couple of really solid months of aerobic work in to feel that my fitness is really gaining some bigger steps. Getting back to where I was when I was 30, kind of trying to get back there a little bit before we then go, okay, let's see what's happening. Make sure we've got some really consistent results in training so that those days of fatigue here and there, you know, those little supplements that are screwing up my leaky gut a little bit, we've really just cleared out everything and had some really long periods of aerobic training. But yeah, not having coffee is interesting. And obviously, the world of endurance sports and sports in general and everyone in general lives on caffeine and they love it.

Geoff

I have some interesting perspective and thoughts on this topic too. And I think, I mean, is one of the most fascinating stats, two billion cups of coffee consumed a day. And it's been a personal vice that I kind of grapple with because I know I should be cycling off of coffee or caffeine more. But it's addictive, it makes you feel good, it's hard to pull away. I'm used to that ritual. But it sounds like you've been able to wean off of it. And I can tell you my story why I felt this is an important area of self improvement. But curious to hear your story, when did you get to caffeine as a point that you wanted optimize?

Pete J.

I never really drank caffeine much until I was about 30. The smell of it was like, I don't really like this. And eventually I got more and more into it. Living with someone who likes coffee, you start to then have a little sip. And then it goes from a sip to my own cup. But I still have never had a lot. I never, you know, it was always, I could have it every couple of days or something like that. So I was never fully addicted. But seeing a holistic doctor earlier this year who's a brilliant guy. And he is very much about the neurological side of what could be inflaming some of my issues. And he just said the caffeine is just no good for you. He doesn't believe it's good for anyone and then there's no really good time to be overstimulating your brain to that point.

And it becomes that pattern of suddenly, a cup or two is okay in the morning and then it's like, oh, well, I'll just have one in the afternoon as well. And then that's wrecking your sleep. It's a slippery, slippery slope. And I was able to, I cut back to decaf for a while because I wasn't doing it for the caffeine, I was doing it for the placebo. The taste of it, the hot drink, and the placebo of it tastes like caffeine. That was my perception of it. I very rarely got a buzz out of coffee. It was much more the taste that gave my brain the, oh, you've had coffee so you must feel good. I could have decaf and be like, you know, I feel great now, I've had a decaf just from the taste of it.

Geoff

Well, there's still a little bit of caffeine in decaf, there's like 12, 24 milligrams, which is nominal, but just for the folks listening, there's still a little bit.

Pete J.

It was the habit.

Geoff

Yeah.

Pete J.

Absolutely. Which is why I then went okay, I've got to have no decaf, not even, that's too much of a stimulation to try and get everything, vagal tone and body as healthy as I can. And then it became, okay, I've got a not habit because of the inflammatory autoimmune leaky gut issues. But it just, it's just a habit. It helps if you can replace it with something. So if you're not on a no plant diet, then you can easily replace it with some decaf tea very, very easily. Awesome herbal tea that's decaffeinated, caffeine free.

Geoff

But this is very, I would say that almost 99% of athletes that we work with or we talk to, I mean, they pound 200, 400, 600 milligrams of caffeine before the race. I mean, I'm sure you have competitors, colleagues, folks you train with that are just right before the big day, boom, like a huge hit of caffeine. And people swear by that and there's good data on suggesting why that is actually useful. Curious to get your thoughts, I mean, this is, the data for caffeine is very, very good. I would generally say that it's one of the performance enhancing things that generally people accept that work. As you're a competitor, you're an athlete, do you feel like the net gain of not having to rely on caffeine is going to give you more long term performance or do you feel like okay, maybe I just don't train on caffeine and then I just save it for the once every quarter type thing where is use it as a huge hit before race? Curious, as as you start being really thoughtful around caffeine, how do you imagine using this as an ideal protocol?

Pete J.

It's pretty tricky because everybody's different of course and I've chosen the food and the drink and what I do because of I'm trying to get my health best and I've got certain health issues that need to be addressed in a certain way.

Geoff

So you're saying that from the leaky gut perspective, caffeine's just a non starter. So just even getting you gut to normal is going to be a bigger performance gain than any potential risk from the caffeine addition.

Pete J.

Yeah, and just having my brain at a more relaxed state more often and not relying on caffeine. It's also, you know, I think it's an issue when people are saying, I can't get going until I've had my coffee in the morning. And it's like, well, if you can't live like a normal human being without a stimulant every single day, you know, you may as well be addicted to any drug really, it's an addiction, and you need it.

So out of the way, these are my choices for my personal health issues because I don't want to tell everyone that they're doing the wrong thing because it's something that they love and they're very passionate about. But it's sort of like, if there's, as with going carnivore or as with going keto or cutting caffeine out, it's one of those things that you can do if you've got some health issues. So if there's something in your body that is not as good as you need it to be or want it to be, then these are things that you can improve on.

So I went taking it out because I believe that I've still got plenty of room for improvement in my health. But I will use it say towards the end of an Ironman race in the marathon, and I'll just use like caffeine tablets. But I only went I need it and still only in moderation. I wouldn't be taking like hundreds of milligrams. I think the year that I got second, there's a bit of a video of me, and I look like I'm showing my fingernails as I'm running, but I'm actually just biting half a tablet off the other half and then wrapping the other half back up and putting it back in my pocket. So I only had half at a time.

Geoff

Which is what, like 50 milligrams or something?

Pete J.

Yeah, it would have been about 50, 60 I think at a time. So things like that. And then there's the side effects as well of actual having the coffee. And a lot of people, a lot of athletes are getting stress fractures and other issues of so, let's say, first of all, they're not really eating a lot of protein and the bones are made of proteins.

Geoff

Or minerals, calcium, right?

Pete J.

Yeah. Predominantly, it's the proteins that build them up. So a lot of athletes aren't eating enough protein. The coffee can also leech a bit of those minerals out. And then you've got the small amount of protein that they are eating if they're eating red meat with iron in it, chances are they're probably having coffee around some of the food that they're eating, and the coffee can limit the amount of iron that's absorbed as well. So then you might have people with low iron issues as well, those that are drinking a lot of coffee. So a lot of coffee, low red meat intake, a lot of low iron issues as well.

Geoff

On top of I imagine, I mean, just repetitive motion. If you're running marathons, that's a lot of impact. Still, yeah, I mean, I think on the margin, I would agree that after just doing and heavy, heavy training, that's a lot of impact, like a lot of fractured damage, your bones are accruing. And then if you do the nutritional deficiency on top, that's where risk happens. I can see where if you tied those two together, you want to be thoughtful around the caffeine and nutrition intake.

Pete J.

Again, even anyone with osteoporosis type issues or just general people with low iron even if they're not athletes, it's a slightly detrimental, it's a stimulant and it's also not great for your brain. The whole living in the moment.

Geoff

So how often are you taking caffeine then at this point? Like zero times a year?

Pete J.

So I don't have it.

Geoff

None at all?

Pete J.

I'll only have it in racing, like half a dozen times a year in a race. And that's where I'll use the Ketone Ester instead of caffeine. And people could say, oh, it's so expensive for what you get, but I've found I can bump up my ketones by about .5 by having about five mil. It's almost the price of a coffee to get a healthier benefit that's going to do more for my body and my training and better for my brain for basically the same price if I just had five mil at a time. That's my take on it anyway. That's what I'd rather have than the caffeine.

And when people are really addicted to it, it comes back to another big point that I really try and practice and what I was doing when I won in 2012, which was being in the moment and not letting ego rule what you're thinking or feeling like, oh, how far have I got to go or geez, I haven't had my coffee today so I still feel tired. Or you're in the moment and that is all that you know, you don't know anything else outside of this very moment. And it's hard to be, and if you add a little bit of gratitude into this moment, then you can't be feeling like you haven't had your coffee, and therefore, you're still cranky. Oh, my gosh, I've still got this far left of run, therefore, it's going to be such a tough thing to do, I don't think I can do that. So, that's something that I try and practice quite a bit as well, to be in the moment, not rely on the thoughts of the past or the future to rule how I'm feeling.

Geoff

Yeah, I'd love to unpack that more. Over conversations like these and me dabbling into the endurance events and doing marathons or doing ultra marathons and cycling and doing miles on the bike, you just realized that, at least for me, I've found to do these types of events more of training my mind versus training my body. Obviously, I like the aerobic benefits and the body composition benefits and longevity health benefits of exercise. But I think what matters for me because I'm not ever going to be, I'm not going to be a world champion athlete, but I care about my mental performance and mental acuity as a business person and all of that.

I think the most interesting part of talking to folks like yourself is that you're in the pain cave where you're in your own thoughts for five, six, seven, eight, nine, 10 hours at a time. And it sounds like just hearing you talking about gratitude and being the moment I think is something that I've come to appreciate at a deeper level. I'm curious to hear you talk through some of the like maybe the obvious question when even people ask me and I don't think I'm like a big insurance person, but they're saying, you're running for three hours, what do you think about? I mean, even at that level, maybe we unpack it from that level. You're out on a triathlon, you're on Ironman, that's, you know, depending how good you are, six, seven, eight, nine, 10 hour ordeal. What do you think about?

Pete J.

Just trying to be as efficient as possible in every single second of the race basically. So, there's 1000 decisions that need to be made throughout the race as well, as in when to drink, when to pass somebody, when to be patient and stay behind, how hard you should be going, is this hill, you know, should I push over this hill or should I just kind of cruise up? So many decisions that can affect the outcome of the race. And if you're not calm and in control and in the moment, then you're going to make the wrong decision somewhere along the line that can affect the outcome of the race.

Geoff

You're actively in the mind. I mean, do you ever just zone out and just kind of autopilot? Because like sometimes there's, you're out there for like eight hours. So for eight hours straight, you're very much conscious, like I got to keep my form good. Should I try to pass here, should I accelerate here, should I feel here? You're looking at your watch, you're checking your power. So you're very active throughout the entire ordeal?

Pete J.

Pretty much, yeah. And it's a bit like driving a race car. You're kind of going pretty quick so there's always movement, you've got to stay pretty aware of everything. Even on the run where you're not moving as quick. For me, it's really about keeping my form. So, I'm trying to really focus on form and stay completely in the moment. It was a big thing that I practiced in 2012 in training, was getting rid of all doubts and fears so that my mind was not distracted by any of those and that I was able to concentrate on form and technique and getting as efficient as I could. And I'd seen a kinesiologist before the race and he said, through muscle testing, he's like, you need to use the word love more. And I was like, oh, all right.

So sure enough, I'm out there training and I'm, this is the year where I was really doing everything I could because I wanted to win. So I was visualizing the rice a lot and I'd been there quite a few times. So, every time I hit certain hill in training, I was picturing a certain hill in the race. So I was living the race in training all the time. And I would visualize, like, say, a sprint finish between one of my major competitors. And even just visualizing that in training was enough to give myself a little bit of doubt while I'm doing my run effort. And just by saying the word love, that was enough to bring me back into the moment of feeling grateful and feeling that sense of gratitude brought me back into the moment and cleared all the doubts, and I was running strong in my effort again.

So, it's not so much, so the word love was what I used at that point because that's what I'd got. But it's, looking back now that I've learned a lot more about how it was all working, it was just a thing that I'd practiced, a word that got me back into the moment and cleared all my doubts and fears. And there's 1000 different ways that someone can do that but it is something you need to practice to be able to switch it on quite quickly.

Geoff

It's like kind of a totem, like a verbal crutch, or a totem, a reminder that set you back into what I imagine is a flow state where you're sort of calm. And that's interesting because it sounds like when people are in competition and not everyone's competitive, but I imagine people have done some competition or some performance where they feel nervous or nervous energy, and it sounds like that might be beneficial in some cases. But what you're saying especially on these long multi-hour races, you really want to find that flow state of being calm in the moment and almost have this sense of gratitude that you're happy to be moving and alive.

Pete J.

As as you asked though, do I zone out. And being in the moment in a way is kind of zoning out because you have no thoughts in your head whatsoever. I mean, that's when you've really practiced it well. You can clear your mind at the snap of your fingers and there's no thought. So it's not exactly you're zoned out. You're totally aware of everything that you're doing, everything that is around you, but only what exists in that very moment. And in that sense, there is no thoughts because generally your thoughts are the future or present, or our future or our past. So yes, clearing your mind helps you stay calm, helps you make the right decisions, helps your body be relaxed, helps keep their central governor compressed. I loved your-

Geoff

Tim Noakes.

Pete J.

... chat with Tim Noakes the other day. I've listened to a lot of his chats before. I really love the central governor theory. So, that's just one way of minimizing the energy loss I guess and a way of making sure that your body is feeling safe. And that's kind of a word that I use a lot as well is that if you can give your mind the sense and the body the sense that it is safe, that it's not under stress, that it's not starving, that it's not in a worrisome fearful place, then you can just control the central governor reaction and therefore get more out of your body. And so, I was able to be totally calm and in control in 2012. I even, like I'd practice, and I knew that my back would tighten up off the bike when I started running. So, about six or seven K in, I was eight minutes down from the leader in second place and I needed to stop and do some hip stretches because I knew that that would loosen up my back. So I quickly did some dynamic stretching. And looking back, that's such a key point of what helped me win was that I was eight minutes down but still calm enough and in control enough to go, I know what I need to do to get from A to B as quickly as possible with the least amount of stress.

Geoff

And you can make up eight minutes in a marathon even while stretching out, which is incredible.

Pete J.

He'd blowing himself up on the block pretty hard, that's how he had such a big lead, and he got about halfway in the marathon and pulled out right there and ended his race there on the side of the highway.

Geoff

Brutal. I was going to say, making up eight minutes on a marathon.

Pete J.

Well, that's not a lot.

Geoff

But I think it is like, you know, you're shaving off 20 seconds a mile for 26 miles. It's hard to make up that much time for that long.

Pete J.

But when you're at the end of an Ironman and if it goes pear shaped, it goes really pear shaped. Guys will end up walking, you know, I've done plenty of Ironmans where I've ended up walking and that's, seven minutes will go very, in about one or two kilometers, seven minutes will be lost

Geoff

It's a long day out. I think what you talked about with the mindset reminds me a lot of what meditators or folks who practice a lot of the sort of inner mind training with meditation or Zen practices, they talked about very much in the same language you just described, which is, you're 100% clear and have acuity on the world, but you're in flow, you're not really thinking about anything but you are fully present. I think that's one thing that I talked to a lot of my colleagues in the office around endurance athletes, getting that state of flow is very much like being in an enlightened or very meditative state. And I think there's definitely some parallel there. And I wonder, if you have a brain scan of you in that state versus a Zen monk who's in a meditative, enlightened state, if that's a similar brain pattern. That would be an interesting experiment to run. I'm curious, have you thought about meditation or sort of the visualization side of things? I mean, sounds like you've obviously been thoughtful around your mental state. I'm curious, have you done meditation practice and all of that.

Pete J.

Not that I don't believe in it, but it doesn't work for me. The sitting there or laying there doing nothing while quieting my mind, I don't get much benefit from that. But I've worked with a guy who does some amazing tremor therapy, and it's all about quieting your mind while doing gym exercises. So, while you're under load, so while you're putting your body under stress, you've got an incredibly present mind and you're not even acknowledging that the weight is there that you're moving. And that for me is, and I can do the same thing while running or riding or swimming, you're trying to not acknowledge that you're doing an effort while you're doing an effort. So you're getting this much, much more powerful connection and much more powerful adaptation through your mind, your cells, because it's not just about the mind that needs to be trained to relax, you know, everything's connected. So if you can train your muscles to do a heavy load or any effort at all, even just moving without acknowledging that you are doing that effort or that movement, the connection just is like tenfold in terms of the impact that you get, the adaptation for training your body to be relaxed while you are pushing it. And therefore, then your mind is more relaxed because your body's more relaxed and vice versa.

Which one comes first? I don't think you can sort of, you can't separate them. They're very much joined. If you walk around with your shoulders tense, your mind will be tense. And if you have a tense mind and everything is going wrong, then your body will tense. But you can change one by changing the other but you've just got to be aware of at least one of them. But yes, this gym work, his name's Ken Ware and does some amazing rehab with people who have had issues of all sorts, whether it's a friend of mine, John Mclean who's in the Hall of Fame in Ironman. He was the first wheelchair athlete to complete the Hawaiian Ironman. And he was a partial paraplegic. He went and worked with this guy, Ken Ware, and he was able through being completely present in the moment and having the belief that he could move his feet and not letting any other doubts or fears block that pathway, he was able to reactivate more nerves after 25 years in a wheelchair, you know, and he no longer needs a wheelchair. So, it's incredibly powerful if you can trigger the presence of being in the moment, a calm mind with a belief of I can do this, at the same time, not acknowledging that you're doing something that should be difficult or hard. It's an incredibly deep response that you can get. Yet, I just find that type of training much, much more impactful than sitting there or lying there trying to meditate without any movement.

Geoff

Yeah, that seems to be my experience as well and my sort of correlation of this concept is that I think the end mental state is similar if not the same, this sort of flow, calm, 100% sharp acuity state. But there's different ways to get there. One might do that through a sitting meditation versus meditation through sport or practicing your craft. And my sense is that, depending on the personal journey of that person, there's different ways to get to that same sort of enlightened state.

Pete J.

People might just get it from a hobby. Sitting there calmly doing a hobby that just clears their mind of all other thoughts and anxieties, that's why hobbies are so important.

Geoff

I think there's something to that. And hopefully, I'm not sure how one would formally study this. But that is my suspicion that some people really, you know, I imagine that some people can really get to enlightened state with meditation. I think one of the points that really struck me was that how many tens of hundreds of thousands of people are Zen monks spending 12 hours a day sitting there. Are they all super enlightened? I don't think all of them are super enlightened. So I think that, so I think to me, that suggests that's one specific way that might get you there but it's not the only perhaps way to get you there. But I wanted to get to the point around feeling relaxed in that state, because, and maybe this is me being in a state and not feeling relaxed. I mean, I can hold that state of I'm running a marathon, okay, like the first 20 minutes, first 30 minutes, okay, like, I can self talk and motivate myself and, okay, I'm going to keep flow and keep focused.

And obviously, you've been world class at this, to be able to hold this at a very, very high level, world class level. Are there any practical tips for listeners? For me, like how do you, is there self talk or some sort of mantra that you can bring yourself back to that state or is just practice and visualization and just doing it over and over again to break down that magic? That sounds obvious, right? Like, okay, just feel relaxed when you're running a marathon. Okay, I get that. Okay, try to do that when you're 20 miles in and you got six miles to go and you're tired.

Pete J.

Definitely takes practice. But yeah, you need a few cues, as I mentioned before, like, for me, it was the word love back in 2012. Nowadays, it's probably more just an awareness of where my breath is going is a good start. So, if I'm breathing up into my upper chest, I'm more likely to be tense and not letting my body relax. So I focus on breathing into my belly which relaxes everything. And I try and practice that day to day when I'm doing anything, you know, sitting in a car driving or reading a book, I'm trying to do five seconds in, five seconds out. And that's really good for vagal tone as well.But obviously, you're not breathing that slowly when you're running. But just by recognizing where the breath is going, you can relax the rest of your body a bit. Definitely, a lot of it's around the neck and shoulders and the trapezius.

That's a key, like even just a tiny bit of tension there when you're running will give you tension in your mind. So that's super important just around the shoulders and neck. And then in terms of mentally what you can change, I use a sort of trick where I try and pretend I'm already at home on the couch having done the session. And so, you take your mind to laying on the couch totally like relax, let your body go completely floppy as a ragdoll. Now, feel that while you're running. And if you can practice that, so it's particularly towards the end of the run when people in training or in the race, when that's when you'll be most tense and be like, I'm nearly there, I'm nearly there because your ego's starting to get ahead of you. So in training, when I'm getting close to home, and I'm nearly done, I'm nearly done, I pretend I'm already done.

Geoff

You relax even harder into it as opposed to like-

Pete J.

And just be like, just let it go and be, a, be in the moment so that you're no longer thinking how long do I have to go, you are just totally in the present moment. And b, that feeling of how it will feel once you're done. Let that tension go while you're still running because everything's visualization and perception. Perception is everything. So, just perceive that you've already done the run, you're already chilling with your mates or lying on the couch relaxed. Whatever it is that you get that sense of calmness and that release of tension doing, whether it's, the opposite is, if it's a really, really hot day, though, don't visualize jumping in a cold pool at the end of it because suddenly, it will feel much hotter. If that makes sense.

There's a catch 22. If you're in a really hot race and this is what I visualized training for Hawaii Ironman is, imagine telling yourself it's really cool and that you can feel a breeze on your skin. So in training, if I was running in the middle of the day and it was a hot day, I would take my mind out of the heat and put it somewhere where there's a breeze on my skin, the sun is not actually that hot. And I would tell myself it's not that hot. So that's a mental trick if you're struggling with something that is present right now. Just reverse it and just say it's not that hot or this is not that hard.

And that's what, I mean, to me, that's what heat acclimatization is, is the mental side of it more so because the physical aspect of it is you sweat more, which isn't really beneficial come race day. And training in the heat can help increase a little bit of blood volume I think just because it's harder, though. You get the same from altitude training. It's just harder. So potentially, that's good for some people that can handle training harder. But for some people like me, training harder is not necessarily going to be the best way to get my body to respond well. So back to you ignoring that it's hot is a really good way. And it's a bit like listening to the seals who train in the cold. And they're very good at it, you know, they've been pushed in the ocean and stuck out there freezing and they very much have to tell themselves, this is not that cold. So it's the same thing. Mind over matter is absolutely how you can have a better performance.

Geoff

No, these are very good tips and I think some of the concepts that you're mentioning are things that I've been trying to adopt and implement. And I think for the folks listening, it might sound easy. Think about a cool breeze while you're seven hours into an Ironman. It's not that easy when you're actually out there sweating and tired and hurting with blisters on your feet. But I think that's how to get there. I think that's where I talk about endurance sport as really a mental training for other aspects of my life.

Again, I presume that most of our listeners are never going to win an Ironman, right? I mean, just, there's very few people that can even genetically, athletically get there and put all the training on to get there. But most of us have jobs or livelihoods that deal with stress. And I think that if you have confidence to be able to deal with stress in a very physical context, where you can overcome it and train your mind as you're running 10 miles or five miles or whatever miles that you need to do that's challenging for you, some of these same principles I imagine, at least I found for myself personally, translate really nicely into the, I was going to say civilian world but all of us are civilians, the business world or the non sport world.

And I'm curious to get your thoughts there. I mean, clearly, you must have some confidence that you've gained from being the best in your field and perhaps have you been able to translate that confidence or that endurance into other aspects of your life. Do you feel like you're just a more enlightened, calm, efficient person because you've just gotten so deep in, and it sounds like you were clearly self reflective on the process to even get there. Curious to see if you've been able to channel that thoughtfulness to other aspects of life.

Pete J.

Yes and no. There are periods where I'm quite good at, okay, this is what I need to do and I'll practice it, such as just taking five minutes to do some slow breathing and totally be present. And if I can do that a few times a day, I know that I would have a calmer mind for the other 23 and a half hours of the day. But I haven't been doing it lately and I noticed that so if I don't keep up the practice of actively taking a few minutes here and there to calm my mind, then I am noticing that I'm slightly more anxious, slightly more distracted and less in control of my own choices I guess.

So ego starts creeping back in. And your ego, if you're not practicing, staying on top of it for myself, it is creeping back in and it's distracting me, it's giving me anxieties, it's giving me doubts and fears, and I'm not able to concentrate on what needs to be done immediately as well. So, I do need to do that a little bit more often. And even if it's 30 seconds of just breathing and staring at a dot on the wall, and just thinking of completely nothing and being in the moment, when I do that, I feel better. So I just need to bring that practice back in a little bit more. But otherwise, I've got all this information and like I say, I'm really, I know, I understand how it all works, but yet, being in control of it, of myself more often, it's something that I have to practice or else there's no good. I've got the information but without practice, it doesn't come to the forefront at all. So I think that's all I can say is that it takes practice all the time to be aware of it. Some people, it's better and easier.

And I think, as I said, I mentioned before, some issues that I've had with brain activity in the past or issues of feeling depression or just leaky gut issues that are affecting my dopamine and other hormones. So maybe it's not 100% of my own devices, of my own control that sometimes are affecting my hormones that mean I can't do things as well and feel these other fears more often. And certainly, even, let's say, my doctor, he said, your estrogen is quite high because I've had low testosterone for a while as part of fatiguing my body that I've done. And he said, so you might feel a bit anxious or emotional, he said, just try and ignore and let it go because it's just the hormones.

So there are times and for certain people that yes, you do need to practice quite hard and some people will practice, need to practice more than others. And others just have the hormones that are just going to keep them absolutely centered and in control and motivated. And that just comes more naturally for some people because of their hormonal balance. And they don't have to go to the lengths that I have to go to try and work on getting my hormones and getting my cells and energy systems and everything working well.

But when you really look at those people that on the outside, they seem good, sometimes there's just those little things that, they're not, if you don't look at the health in the whole big picture, there'll be some things happening there not attributing to their lifestyle or their nutrition, and they just got, that was bad luck. And it's like, you know, you and I, those that have actually like understood how is all connected, are probably more likely to be able to go, well, I can give you like half a dozen reasons why that's happened to you because of the things that you've done or the things that you've eaten. So yeah, it comes easier for some but others got to work harder at it.

Geoff

No, I think it's well said, and some of my understanding of the experience as well. I mean, no one's a robot who's just perfect. And I think there's times where you need to just, there's effort every single time. I think people that have practiced at a high level. And again, you've very much achieved that to a very high level. It was just a lot of practice and dedication and all the factors that you mentioned. But I think to our listeners here, it's not because Pete is like a robot. It's like, there's effort on your part as you're doing this effort when I'm trying to put myself into very strong, grateful, clear mindset, it's this effort involved.

Perhaps the takeaway message here is that don't be disheartened if it is hard. It is hard. Just get back on the horse and keep trying and it eventually gets easier and easier and easier where it's more of a second nature. But even an expert like yourself, you sometimes have that lows, and it's fine, that just like we're not static, perfect beings. There's some on days and off days where we just got to be, trying to lean more towards the on days, right?

Pete J.

Absolutely. I mean, looking back to what I was doing in 2012, I mean, I trained almost all on my own for two or three months. And that means riding about 17 hours, 15 hours awake, mostly out on the road just with some music playing in my headphones. And that was incredible training for being in the moment and just being present and not concerning myself with any other thoughts. I had nothing else going on in my life back then. Jamie was looking after the food for me. All I had to do is train, eat, sleep, and had no worries or anything. So, there are times in your life when it's going to be easier and times in your life when it's harder. But using exercise as a time to be really calm and relaxed, as I said, that's a really good time to practice that being in the moment and making it easier for those other times to trigger into that state of gratefulness or being in the present moment.

Geoff

I have nothing to add there. 100% endorse that. Curious to hear your plans for the future! So obviously, you're on the comeback trail here. Sounds like you're really healing your body up. What are your plans for rest of 2019? How do people keep track and get your updates?

Pete J.

Yeah, well, they can keep track and get my updates on Instagram and Twitter. Twitter, I'll use mostly for the health side of things. I don't really mention on Instagram the stuff about me, only eating meat and not eating plants because it's not really the platform and people tend to push back quite a bit, particularly in my community, the triathlon community. I mean, they can be quite anti low carb, let alone anti plant as well. So that's quite interesting. But yeah, I love Twitter and getting involved in some of the health conversations that you post and all the other doctors that I follow are into. But I'm racing a couple of races in Asia in June. So Jamie and I actually excited we're getting to race Japan 70.3 Ironman, and then spend a couple of weeks living in Kyoto, we're going to stay there for two weeks. And then race challenge half in Korea. So, that's a couple of good races in June, and then come back and just do a big block of training.

And then the summer here down under, we'll start sort of September, October, November, and start racing quite a bit. And then if I'm continuing to improve, I'll race an Ironman full distance early next year and try and qualify for Hawaii 2020. And I'm only going to go back to Hawaii if I think I can, if I'm in better shape than I ever have been, if I believe that I can run faster than anyone has run there before. Because I know that's what it will take for me to get on the podium again. So, I only want to go back if I'm going to do really well there. So, it's a long way off, it's a long journey to there. I've still got a hell of a lot to learn because it's quite, you always mentioned that there's so many nuances just with the carnival diet or just with looking at ketones or this or that. Then you throw in the trying to train for an Ironman.

Geoff

Yeah, the training. Training itself is another beast.

Pete J.

As basically a zero carb athlete. And I'm trying to google and read articles and not just articles, but trying to read some of the papers around what's going on with gluconeogenesis and all the other factors that is going on, and where's my energy coming from, where's the glucose coming from, where's it going? What's happening to the ketones, where are they going? All of that kind of stuff. And figure out the optimum level for fueling because it's quite hard. Because on race day, the adrenaline, the heart rate, the cortisol, like everything is higher. So, you're going to get a different response in blood glucose in a race than I am in any training that I would do. So even if I can test my blood sugar 24 hours a day in training and my ketones, it's going to be a different story on race day. So just, it's going to be a bit of a journey figuring out how can I get to Kona 2020 with just a complete understanding of what's going to be happening in my body on race day? And how can I fuel it best for that task? And yeah, it's really interesting. There's not a lot of papers on zero carb athletes training to be an Ironman athlete.

Geoff

No, absolutely, you're at the cutting edge.

Pete J.

And I just want to stress, it's not something that I'm like, hey, I just want to do this to test what's going on. It's like, I'm doing this because I've found out that my autoimmune reactions that have plagued me since I was a teenager have ended me up here, not being able to eat plants without getting a leaky gut symptom. I still cop it from athletes that just say, you're just being extreme or you can't do it without carbs or why don't you just do this. And it's like, they just completely overlooked the fact that this is an issue I've been dealing with for 20 years and it's affected my career greatly. I'm just doing everything that I can to try and get back there.

It just so happens that it's on the other end of the spectrum that no one has really even looked at before, let alone tested and figured out, as you talked about, like respiratory quotient tests and how fat adapted can we get and then what do we fuel with to optimize that level of adaptation. But it's a good time. Basically, it's an exciting, I've come along and family sold out at the right time. If I'd found this out 10 years ago, and let's say the esters were still 10 years away, I would be scratching my head about how do I optimize this in a race because it's, it's just exciting to know that I can, I can basically, it's just doubling down and be like, hey, I can take in a minimal amount of carbs in training, which is great for my guts and not have to put in anything much at all. And some days I put in nothing almost. And then to know that on race day, I can not risk blocking up my guts and having cramps or having any IBS type issues and cover that energy with an ester and be like, hey, I know that I'm going to be okay.

I think there's always an aid station. If you get to that point where it's like, oh my God, I've run out of sugar, it's like, oh, there's a coke just here. Okay, great, I'll have that. It's really interesting time anyway. And with all the doctors and all the conferences that are out and published online and podcasts like yourself, and I can listen to all these amazing doctors, and people that have also experienced it and researchers and journalists, it's a really exciting time. So, I don't regret that it's taken me 20 years to figure it out. It's just been a really long learning process. And the timing is right. So, I'd love to get back to the top of the world and show that there's there is a different way to approach it than the high sugar approach that is affecting your health potentially.

Geoff

Incredible journey, incredible story. I think when people realize the extent to which you've understood your body, I think hopefully they understand that this is not just some extreme stunt that you're doing in terms of going completely off plants. I mean, you've almost done every other possible "traditional intervention" here, and this is the only thing that's working and sticking. So, I'm very excited to see the journey, follow the journey and hopefully we'll see you on the podium in 2020 Kona. I mean, that would be an incredible ride.

Pete J.

Like I said, we're a long way off that and I can barely even think about it. I'm just trying to take it basically still day by day. It's still like, I'm still trying to nail down exactly what's going on in training for my blood glucose levels, for my fuel where it's coming from. It's a long process, but yeah, it's a really interesting one and I'm really enjoying learning all that I'm learning.

Geoff

Awesome. All right, thanks so much, Pete. This was a fun conversation.

Pete J.

Thanks so much for having me.

Hi, Fat: Challenging Carbohydrates, Brain-body Connection, & Reversing Diabetes ft. Prof Tim Noakes

Originally posted on HVMN and authored by Zhill Olonan and Geoffrey Woo on May 20th, 2019

Even as the fear of fat declines within the public eye, you've still probably experienced disbelief & bewilderment from co-workers, friends, or family when talking about your ketogenic lifestyle. Imagine being a high-fat, low-carbohydrate proponent as an esteemed scientist nearly two decades ago.

With more than 750 published scientific articles & 70 marathons under his belt, Professor Tim Noakes is well-known for his many contributions to nutrition & exercise science. At the beginning of his research career, he was an advocate for a high-carb diet, which is no surprise given the medical dogma at the time, yet Noakes completely changed his mind when he learned about the value of the high-fat diet.

Not only was he an early leader in the ketogenic movement, a stance that temporarily costed him his medical license, but Noakes actually reversed his own Type 2 diabetes through a low-carb, high-fat diet. Perhaps one of the reasons he has upheld a high reputation is his continued desire to question current scientific theory, even conclusions he first helped define. Rather than turning a blind eye and staying with his preconceived notions, Noakes follows the evidence...a model we should all aspire to have.

In this episode, you'll discover:

  • Central governor theory - How does the brain directly influence physical performance output?

  • Ketogenic diet - Fat-fueled athleticism, improving insulin sensitivity, & becoming metabolically flexible

  • Noakes' commentary on the history, present, & future of nutrition science

Transcription

Geoff

Professor Tim Noakes, really a pleasure to have you on the H.V.M.N. Program.

Tim N.

It's a privilege to be on it with you. Thank you so much.

Geoff

Our honor. So our listeners are probably very familiar with your recent saga, or relatively recent saga, with some South African regulatory folks related to nutrition by your stance and your thoughts around low-carb ketogenic diet for metabolic health and health and wellness. But, on the other hand, you also have really had a storied career as an exercise physiologist. A lot of the common "folk wisdom" around carb-loading or hydration or this notion of fatigue and a central governor theory came from you. Given this storied career and the interesting notion from going from a carb-loading advocate to now talking about low carb, how would you describe yourself at this point in your career?

Tim N.

Well, I'm now every much retired. But I'm not retired, because I'm still very active in promoting low carbs. But if we go back over my career, I trained as a medical doctor. During my training, I realized a couple of things, firstly that I was much more interested in science and discovering new ideas than in simply regurgitating what was already known. I'd rather write the book than have to read it and learn it. I also had saw that the costs of medicine were rising dramatically already in the '70s, and most of it was the treatment of chronic disease. I thought, "Well, that's not a help," because I saw how ineffective the treatments were. And I said, "It would be much better to spend a little bit of the money on prevention." And I said, "Well, there are many good doctors looking after chronic disease. I think there need to be some doctors who try to promote prevention."

So I chose to go that route. I helped develop sports science and sports medicine in South Africa. During that time, as you indicated, I got interested in foods and exercise and how the brain regulates performance, and for a long time thought that carbohydrates were the king; they really were essential for exercise performance. Then, in about 2010, I suddenly realized I got it all wrong and decided that I better stop harming people because the books that I'd written said that high-carbohydrate diets are ideal. I realized I was wrong. If you had insulin resistance and you followed that advice, you were very likely to develop Type 2 diabetes. So I said, "It's time to change." I acknowledged my error, and I said, "I apologize, but we really have to understand that these high-carbohydrate diets are not for everyone." The consequence to that was that I irritated my profession so much that they decided I had to be tried for unprofessional conduct for doing a few things on Twitter which they didn't like. That was actually a front. It had nothing to do with that because everything I said on Twitter was completely correct medically, as we eventually proved.

So I went through 28 days of trial, and what my legal team advised me to do is, "Let's put the high-carbohydrate diet on trial and see which wins." At the end of the day, the low-carb diet won. So we were very happy about that. I managed to save my career because I'd been targeted publicly to be humiliated in South Africa and the world. I decided I wasn't going to let that happen because my whole career would've collapsed, and I felt I had to keep going and make sure that legacy was intact.

Geoff

100%. That just reminds me of Galileo, of these historical scientists. We can let history judge the comparison there, but obviously, within your field... I just want to underline and unpack some of the things we're talking about. Just as a reminder, in the '70s and '80s, sports science wasn't a field. So when you're saying that you helped develop sports science, I don't think it's a far stretch to say that you're one of the first seminal people to really make this a profession, giving the timing and perhaps the... So that's interesting. And then second, which I think is very interesting, is that it's very rare for anyone, but I think especially in academia, to say, "Whoops. I was wrong for 20 years of my career, and I'm going to correct that." I guess we should probably go into the sports field first and then probably unpack just in terms of chronological order here the typical notion of carb loading, hydration, central governor theory. Perhaps we can go through one at a time. Maybe we can talk about carb loading first. That's a meme that's very popular in endurance sports. What is still valid there? Because, obviously, there is some role, potentially, for carbohydrates, especially for performance. What was overstated, and what should we be more nuanced about?

Tim N.

Yeah, absolutely right. Carbohydrate loading came in in the 1960s, and just to remind you that before 1968, there was no real interest in sports science. But that was the year that the Olympic Games were held at altitude in Mexico City, and athletes went to Mexico City not knowing how to compete at altitude. A few countries sent their athletes there to train before the Olympic Games, and people said, "We absolutely don't know what's going to happen to these athletes." That was really the stimulus for the beginning of sports medicine. It was also because the East Germans competed for the first time, and they were successful. They had applied science. Of course, they'd applied drugs as well, but they'd applied science.

Geoff

They're pharmacologically enhanced.

Tim N.

The US realized that here's a real competitor, and we need to get involved in sports medicine. I know that the doctor who went with the US team to the Olympic Games in 1968, he was literally found a couple of nights before the Olympic team went to the games and said, "Would you like to come to the Olympic Games?" I mean, that's how unprofessional, how amateur it all was. I was so fortunate because I started my career in medicine in 1969, a year later. Therefore, the first 20 years of my life, I could actually know most about what was happening in sports medicine because it was still so small you could be knowledgeable about everything. Today, of course, it's such a vast field. Anyway, 1970, I start doing physiology and realize that this is my real passion.

The first studies of carbohydrate loading are starting to come forth, and the people from Sweden are doing muscle biopsies. They're measuring muscle glycogen. And they're coming to the conclusion that this is everything. Carbohydrates in the muscle determines your performance. Of course, we should've been warned. Listen, it's not one thing. You can't reduce all of performance to one thing. But we were so enticed by it that we fell into the trap. When I started becoming a serious exercise physiologist in the 1980s, you had to be able to do two things to be a physiologist. You had to measure an athlete's maximum red oxygen consumption. If you couldn't do that, you were hopeless because that was the one factor that determined performance.

Geoff

Right. VO2 max is a common part in this. People love citing their VO2 max scores.

Tim N.

Absolutely. Our problem was we started looking at VO2 max and we said, "Well, actually, there's such a wide range." You could have the same athlete performance, but their VO2 maxes could be quite different. The other thing was that we were told, and this... If you wanted to publish a paper in those days, you had to say this. You had to say that there was a plateau in oxygen consumption before the athlete terminated exercise. In other words, you were made to see the oxygen consumption goes up, up, up, up like this. Then the athlete tires, and no more oxygen consumption. There's this plateau phenomenon.

That was a gold standard. If you didn't say that, you couldn't publish your papers. And we didn't find that on every athlete. We were using fairly simple systems, and we couldn't find it. So we would say, "We can only find this plateau phenomenon in 10% of the population or of the athletes." So you either had to lie or... We told the truth. Fortunately, then that made me realize that if you don't get a plateau, then it's not the muscle running out of oxygen. And, in time, we realized it's the brain regulating performance, and the system is regulated. It's homeostatically regulated. You can't ever let the system fail because then you're dead. So exercise physiology was based on a false premise that the system failed, and then you got tired. We, over the last 10 years or so, have shown that fatigue is purely an emotion. It's just your brain is using this fake emotion to make sure you don't kill yourself. So that's been a major advance, as you know. But to get back to the muscle... Sorry. So, what I was saying, to be in exercise physiology, first you have to measure VO2 max. Then you have to do a muscle biopsy and measure glycogen in the muscle.

Then you're all systems go. Then you're word class. Now you can do everything. I was the first guy to do muscle biopsies in South Africa. We did muscle biopsies on everyone. We loaded them with carbohydrates. We couldn't find much evidence that carbohydrates were really helpful, but that didn't matter because we knew it was true. We were also the first in the world to develop those goos or squeezes that you run with and you squeeze into your mouth. We know all about those. So we developed them. They're called a Lepin FRN. Fordyce was the great ultra-marathon runner in South Africa. Bernard Rose was the marathon champion, and I was the exercise physiologist. So it was FRN, and if you go and Google Lepin FRN, you'll see that we were the first to develop it. So I'm acutely embarrassed now that we took athletes down the wrong road for so many years that carbs are going to make you go faster. But the end result was, when I wrote my book, Lore of Running, which was very widely read, it said carbohydrates are crucial for performance. The first three or four chapters are all about how nutrition is the key driver of performance, and particularly carbohydrates. I realize now that, actually, the brain is the key driver. So, as I rewrite the book, I'm focusing more on how these chemicals in the periphery, in response to what you're eating and drinking, influence the brain to allow you to go faster. The key is that it has to act through the brain in some way to allow you to go faster.

Geoff

I think we touched upon a couple interesting aspects of the central governor theory. We talked about VO2 max and we talked a little bit about carbohydrate and glycogen. I think I want to say, in the modern era, it seems almost intuitive that the brain is a central governor or critical to performance. I think we all have the intuitive experience that we feel really, really good today; we do better. We feel very depressed; we do worse. Some would say that some of the most interesting findings or results seem intuitive or obvious after the fact. I think it was interesting to hear the history that, in the past, VO2 max and muscle glycogen or carbohydrate availability were the two primal causes. But we're moving towards this notion that, actually, the brain is the central proximal cause, and there's many inputs going into the brain.

So, unpacking specifically on carbohydrates, would you say that... Obviously, if you eat a low-carb diet, you can go through the process of gluconeogenesis, produce carbohydrate from protein, or some of your exogenous nutrition coming in. Given your recent evolution on this topic, is there a role for carbohydrate for heavy weight lifting, anaerobic exercises, or are we very much in the camp now of you don't even need to worry about it; if you eat a well-formulated ketogenic diet or low-carb diet, you can still have maximal performance in anaerobic-style performance?

Tim N.

Yeah. I don't think we have the evidence here to say absolutely one way or the other. I know that there are athletes who can do it, but the reality is that they are probably using carbohydrate whilst they are doing those intense exercise. So it's not as if you don't have any muscle glycogen because you're on a high-fat diet. You do have muscle glycogen. So it would be impossible for us to say that this person is not using carbohydrates when they're doing those explosive events, and almost certainly are. So it's very difficult, but where I think the change has come is, as you become fat adaptive, and what guys like Jeff [Foley 00:13:40] kept showing and our own studies have shown and Louise Burke from the Australian Institute of Sport has shown, is that world-class athletes have an incredible capacity to burn fat and that we've completely underestimated the ability of the muscle to burn fat. I think Louise Burke's study is the one which I really find most interesting because she's not very pro-high-fat-diet.

But, if you look at her data, she shows that within three weeks, she took world-class walkers, race walkers, and she showed that within three weeks of this high-fat diet, during racing intensity at 25k racing intensity, these people were burning 1.5, 1.7 grams of fat per minute and about half a gram of carbohydrate per minute. They will almost completely close down all their carbohydrate metabolism. And they were racing at competitive speeds. My view would be that this is not because they've tooled up the muscles dramatically. It's because all that capacity is there. What they've done is, going on the high-fat diet, they've reduced their insulin and they've allowed, now, the fat to become the major fuel. We have a paper that we've submitted, and I don't want to go too far to say what it's all about, but what we did show was that in high-intensity exercise at any percent of VO2 max, it doesn't matter whether the person's eating a high-fat diet or high-carbohydrate diet. Their performance is the same.

Geoff

Interesting.

Tim N.

So that would be performance of 5Ks, or let's say 3 to 5Ks. So I think we're focusing in now. And if you're running 3 to 5Ks, you've got enough glycogen in the muscle, and you can burn lots of fat. You don't need a high-carbohydrate diet. That's really interesting because I think, once you get beyond that 5, 16, 15, 20Ks, for the average athlete, they can uptool and just burn fats. And they certainly don't need high-carbohydrate diets. That leaves us with people exercising from 100 meters up to, say, 3 to 5Ks. That's where the question remains. Will they benefit by high-carbohydrate diets? That we can't yet answer.

Geoff

Absolutely. I appreciate the nuance there because I think, in the world of Twitter and polarizations, it's easy to be, "Carbs are king," or, "Carbs are useless," and I think, as you're unpacking here for us, a lot of nuance. I would say that one paradigm that I've been thinking a lot about and curious to hear your thoughts is that there is some orthogonality between maximal longevity or metabolic health versus performance. Is there an argument that if you're looking to win an Olympic gold medal at your event, maybe within the sub-5K range as you're describing, is it worth it to spend two years, four years, eight years jamming as much carbohydrate as possible and potentially harming your long-term health? But you maybe get that advantage of having very up-regulated carbohydrate function. Maybe you can do some training around being metabolically flexible; fast a little bit in between.

But the main point is have a lot of carbohydrate during that period for that short-term potential benefit at the cost of potentially decreasing your health span long term. Is there a potential argument to be made there, to basically differentiate or just tease out longevity, health span, versus "I want to just burn the candle real quick, eat a bunch of carbs, maybe give myself diabetes or pre-diabetes in 10 years. But, hey, I have a shot to win the gold medal"?

Tim N.

I think you make the point very clearly. You see, I'm a great example. I was never an elite Olympic athlete, but on checking my own data from when I was 28, I was profoundly insulin resistant. I had a fasting insulin of 30 units, and we like to be below six units. Once you're above six, we know that you've got long-term problems. If you're running with a fasting insulin of six or seven, you will get problems in the long term. And, of course, higher, it'll just come quicker. So I was a walking time bomb, and no one had told me, although I saw the data. We didn't know what insulin resistance was in those days. So I developed my Type 2 diabetes at the age of 60, and I probably had it about 55. But I didn't check for it enough, and my fasting glucose looked okay. It wasn't great, but it wasn't diagnostic of diabetes. But I think if I'd done better testing, I would've known that I actually had had diabetes for 10 or 15 years, or 10 years before I made the diagnosis.

So I'm a really good example of what happens if you take a person who's insulin resistant on a genetic basis and eats a high-carbohydrate diet. You will run into trouble in the long term. So I don't see any advantage of eating one gram more carbohydrate than you need. That's the key. I would like to encourage people to experiment and not to say as I do in the book Lore of Running, that you must just overload on carbohydrates as much as you possibly can. I mean, we were telling people to eat a kilogram of carbohydrate every day. I don't know how they survived on that. Their insulin spiking must have been horrendous.

Geoff

For Americans, that's 2.2 pounds of carbohydrate, which is a lot of food. That's just a lot of food.

Tim N.

Exactly. And I would rather say skid by on the minimum amount of carbohydrates that you need because that's going to be for your long-term life expectancy. That's going to be the ideal. Now, I think athletes are realizing that, that there's no real advantage of over-ingesting carbohydrate. You see, when we were working through this paper about how intense exercise could you do on a high-fat diet, I discovered this study saying that you actually burn quite a lot of fat in high-intensity exercise, even maximal exercise. It's difficult for us to measure it, but it's there. People are burning fat. And the one study by [Larsen 00:20:11], my friend Paul Larsen in New Zealand, showed that the difference between the best sprinters that he studied wasn't because the fastest guys were burning more carbs. They were burning more fat. He used an unusual technique to show it because it's so difficult to measure it. But that was his conclusion. So, again, I just mentioned that sprinters may actually burn quite a lot of fat, and it doesn't fit with the paradigm.

Geoff

How would you explain that? Because, as you said, the paradigm is, okay, if you are sprinting, you're probably reaching VO2 max very, very quickly, and you'll go into fermentation or anaerobic metabolism.

Tim N.

The problem is that a 1920 study is quoted. This is the basis of the fact that you can't exercise on a high-fat diet. There was an intervention where they had athletes or humans exercising on high-carbohydrate or high-fat diets. The guys on the high-fat diet did very badly, and so they said you can't oxidize fat rapidly for high performance. And that's 1920. It's one of those foundation myths on which we build everything. So everyone quotes that study, and then they say that Olympic athletes have to burn carbohydrates to win gold medals. But, when you look for the evidence, it's actually... It's not there. That's point one. Point two is that, as you know, the physiology, as you start to exercise more vigorously and you become more acidotic, you release carbon dioxide from your body's stores. This comes out, and so that falsely raises your respiratory quotient. We use the respiratory quotient to predict how much fat and carbohydrates you're burning. The higher the respiratory quotient, the more carbohydrates you're burning. During exercise, we are biased. We are underestimating how much fat you're burning. That's why we can't really measure it. It took Paul Larsen to show that, actually, we do burn some fat during high-intensity exercise, and it may be much more than we think.

Geoff

Essentially, the argument is that there is... Obviously, you're still breathing. You'll still be able to use fat oxidation, and fat will be a substantial portion of overall fuel expenditure. I think that's a nuance that I think is left out of the Twitter sphere where most... Everyone's always burning a mix of substrate. It's never just sugar, just fat. It's always a mixture.

Tim N.

Let me just add another point which I had some argument with another guy, and then he actually stopped on Twitter. He just went off. I said, "If you're a Tour de France cyclist..." And he's saying, "Oh, but, you see, you've got to have lots of glycogen so you can sprint up the mountains." Well, okay. That's fine. But you could get that glycogen by burning fat. So, if you can exercise at 85% of your VO2 max burning mainly fat, the time you have to go to 90% as you're finishing up these huge hills that they go up, then you've got the glycogen. It's stored in the muscle. It's still there because you stored it the night before, and you haven't used it in the first four hours of this last stage. You're just burning fat. So now you can use more carbohydrates at the final slope.

But that doesn't come into their equation because they're so convinced that you can't burn fat at high-intensity exercise. The question I ask is, so where do you make the cut-off? What is high-intensity exercise? We've studied an athlete, too, at 92% of VO2 max while still burning way more than 50% of his energy was coming from fat. That's how much, if you really adapt... But you have to adapt. You have to do high-intensity training on a high-fat diet. Then you can increase your fat oxidation rates remarkably, even at high intensities. So the future, for me, is that athletes will use less and less carbohydrates in training and do more training on the higher-fat diets to make their muscles burn at 90%. They'll be burning predominantly fat. That's the capacity is there. If it's not there in everyone, the athletes who can do it will be the ones who will be the winners in the long term. In other words, if it's a genetic thing, they'll be selected and they'll start to win as a result.

Geoff

Absolutely. I think that's a good segue into some of the more popular topics in discussion with the folks that we work with in physiology in sport, which is this notion of metabolic flexibility, which you're describing. How much can you switch back and forth between different substrate, and how high can you be burning fat at higher and higher intensity?

Tim N.

The idea has risen that a high-fat diet makes you metabolically inflexible.

Geoff

Really?

Tim N.

It's a high-carbohydrate diet that makes you metabolically inflexible. It's not my idea. My PhD student, Chris Webster, pointed that out to me. We took this athlete who could burn at 90%. He could burn so much fat. And then we did a VO2 max test on him, and he did a great VO2 max in which he burned lots of carbohydrate. So here he was with a capacity to burn 1.7 grams of fat per minute, but he could also burn a huge amount of carbohydrate when he was at VO2 max.

Geoff

Interesting. What I was getting to was that... One, let's talk about adaptation period because I think that's something that a lot of people don't... Or, at least as an open discussion of debate, do you need six weeks to adapt? Do you need two years to adapt? And then part two, which I think was interesting, was that what you're suggesting, what your PhD student described, is that it's kind of a one-way door where, if you're very optimized for fat metabolism, you don't lose your ability to metabolize carbohydrate. But if you're fully optimized towards carbohydrate metabolism, you potentially build up insulin resistance, and that reduces your ability to metabolize fat.

I think that's an interesting point to discuss. But the first part of the question, which is, I think, potentially an open area of discussion and work, is what does adaptation mean? I think some people say they feel really crappy on switching to a keto diet for two weeks. Is that too short? What, in your experience, is the right level to fully adapt, and are there strategies to accelerate that adaptation? Should one consider intermittent fasting, high-intensity interval training on top of reducing carbohydrate intake to potentially accelerate up-regulating fat oxidation?

Tim N.

My general view would be that you don't want to add too many stresses at the same time so that if you are adapting to the diet, just adapt to the diet. Don't now increase your intense training, because it's going to happen. If it happens in six weeks or three months doesn't really matter. In a study we did where we repeatedly tested people over six weeks on short-duration, high-intensity exercise, within two weeks their performance had normalized. So, in this group, just two weeks was good enough. But, on the other hand, I've helped world-class athletes, and some of them say it took them 10 months to really get fully adapted in training. And they notice now the advantages in competition. So I think it can be a long time, and maybe it takes 10 months. But you keep going until you see what the outcomes are.

Geoff

That's a good point because I think if you were to argue or steel-man the opposite argument, it is that "I've been doing this for three months. My performance is still not there. I've been doing this for six months." I guess you could say the argument, could you be in a impossible, looping situation where you just need to adapt longer? Adapt longer. This is argument to regression. How would you counter that argument that "Okay, there's no bar"? There's no true Scotsman. You just haven't done it hard enough. How would you address that concern?

Tim N.

I'd give you six months, and if you haven't adapted after six months, I'd say that's it. You're not going to adapt. And go back to your standard carbohydrate diet.

Geoff

That might be a genetic component that-

Tim N.

There are going to be outliers who don't adapt. That will always happen. I remember one guy phoning me and saying... He was a really good athlete, and he said, "At 20 grams of carbs a day, I can't even get out of bed." I said, "Okay. Maybe we should put you back to 100." On 100 grams of carbs a day, he was perfect. He could do everything that he could do. So we say that carbs are not essential, but it's clear to me that some people do need a little bit of carbohydrate, external carbohydrates, to perform. Why that should be, who knows? But they probably have some sort of slight metabolic difference, and they need carbohydrates to fuel the Krebs cycle and so on.

Geoff

100% agree with that. Now, moving to central governor theory, what are some of the key insights that brought you that notion? Again, going back, it seems intuitive, almost obvious, today that the brain is so important for performance. But, again, rewind 20, 30 years ago. This was a new field of inquiry. Everyone was looking at VO2 max and muscle glycogen as the two drivers of performance. It sounds like you started seeing some data that there was very little correlation between those two markers for performance. What centered you around the brain, and what does that inform us about training? The one thing that's funny to me is that knowing that it's the brain doesn't mean that you can just trick your brain. The best way to almost trick your brain is to exercise a lot and eat well. So it's almost like you might know the mechanism. How do you use that mechanism to inform your training and form your lifestyle to optimize performance?

Tim N.

The key bit of evidence for me was when we started measuring electrical activity in the muscles. For the other model to be true, it predicts that you get tired when you're activating all the muscles in your lower level. That's the point. As you get tired, the muscle fibers start working properly. You have to recruit more muscle and more muscle and more muscle until you've recruited everything, and then you're fatigued and you have to slow down because all the fibers have been activated and they're all getting tired. Now, when we tried to test that hypothesis, we found it was completely wrong, that that's not what happened, that you only recruit up to about 40% of your muscle mass. Then it would decrease as you got tired. In some circumstances, it might increase, but it would never get to 100%. So the model was wrong, and that's where we realized, well then, obviously the brain's in charge.

I think people forget this: that to run faster, you have to recruit more muscle. You can't run faster without recruiting more muscle. That kind of a message still hasn't got through to people. It's "You must eat more something, and then that'll make you run faster." No. You recruit more muscle, and then you run faster. So that was what we began to realize, that that was the case. In time, we realized, where does the brain come in? It's producing this fatigue. And our most recent papers show that the key is that you have an emotional response to how you feel when you're running. So you get all this feedback, and it either makes you feel good or bad or whatever. Then you get an emotional response. In our clinical trials where we race athletes against each other in the laboratory, the moment that one athlete goes ahead, the other guy starts to feel bad. His emotional state gets worse.

That's the first thing that happens. And in the second thing that happens, he starts questioning, why is he doing it? Is it really worth continuing? That's called the stopping wish or the quitting wish. Those are the three components, which we now understand in the central governor model, is that, firstly, there is feedback from the periphery, from your internal, and from your assessment of the environment. Then there's this emotion. How do I feel about what I'm doing? Is it making me happy, or am I not happy? And I'm feeling distressed. Finally, you start asking the question, "What's it worth? Do I really want to continue hurting myself for another hour to win the gold medal? Maybe I can slow down and win the silver medal, and that's acceptable." So that's what's going on in your head. And then you asked about training. Well, I think that training is to convince yourself that you can cope. But much more important than that is, what's the goal? Why are you doing it? That's the key. The coach has to get that across to you that this is really important and that you are the only athlete in the whole world who can do it.

Geoff

Yeah. One of the elegant things that you've written or you've said in the past about this notion is that, well, we've all been to the point that you think you're going to die in performance. But then you just... You go a little bit further, or you take a 30-second break and you can keep going. Obviously, you're not even close to dying. So there is something going on that's preventing you from hurting yourself, which I think is a very intuitive way to explain this physiological model that you're describing. Given that the brain is so central to performance, obviously, traditional exercise is very focused on physical exercise to gain performance. If the brain is so important, could we hypothesize that things like meditation or mental training or working on your mental fortitude to absorb pain and really define what your goals are... Is there a role to just look at the brain as a substantial portion of training where I think that is starting to come into vogue, I would say, in recent years? People start working on the mindfulness of the athlete. Does the model that you have suggest or propose specific protocols to work on the brain? Have you looked at that? Is that something of interest? Are there any potential strategies or hypotheses you have there to optimize training of the mind?

Tim N.

I haven't really thought about that. I've been involved more in the physiology, and I haven't really spent my time, "How do we train people to perform better?" Yeah, because to me, this is a black box still. I have to leave that to other people. I think my contribution was to say you've got to look at the brain. You've got to work on how people can train their brains. I think that there's so much to do with it's either genetic or the way you were brought up as a child that is so critical to performance. I'm reading a book at the moment, and it looks at some of the greatest teams of all time, teams that perform beyond belief. So this is not individual sports. It's the team. An interesting thing that they discover is that when you get a team together, each of them underperform slightly. By themselves, they're able to perform slightly better. But as soon as you get in the team, they all sort of become dependent and let everyone else do the work. That's really interesting. It turns out that the best teams, that all comes down to the leader. It all comes down to the captain, that he's able to lift the team to a different level because of his own leadership skills. So there it is. He just manages to get these guys, or she manages to get the girls or the boys, to perform at a higher level and not to let their performance go down because they're a team.

Geoff

That's interesting. Yeah.

Tim N.

It's fascinating that the natural inclination is to underperform. That's the natural inclination. But there are certain individuals. That's part of point two, is if you look at some of the great athletes of all time, they came from abusive families. They had a family member who abused them. I'm talking about physical, not sexual but physical abuse. It was coping with the physical abuse of the father particularly that allowed them... When they got discomfort in exercise, it wasn't an issue because they'd lived with this abuse for so long. That may be the one, but the other one, of course, is just a father that disappears from the family. These are like psychiatric illnesses that help people do better. So it's very complex, and it's not always the way you think it might be.

Geoff

Yeah. No, it's an interesting proposition where... to have an outlier, extraordinary performance, you have to have some sort of extraordinary starting point or initial condition. Potentially, that's the line between madness and genius. If you are that far outlier, you literally are the best human out of seven billion humans at something. There is some strange initial condition likely, and that might be really, really bad, negative six standard deviation or positive six standard deviation. I think, going back to your story about leaders really buffering up the whole team's performance, I think that really resonates with me in our conversations with groups in the military, groups in sports teams, this notion of leadership. If you have a bad team leader.... People in Navy SEAL training are buds. Talk about that. You swap a team leader. The boat-racing team that would always win with that team leader. You swap the captains with the worst-performing boat. That next boat race, that worst-performing team is now winning those races. Do you have some sense of what are characteristics of that leader? What can we learn from this? What can we model ourselves after? Do you have some sense of pattern there?

Tim N.

I worked with a team that won the Rugby World Cup in 2007. You could walk into the room and know this team was unbeatable. It was this sense of purpose and discipline and character and do the right thing when you have to. It was pervasive. It was astonishing. I think there were four or five great leaders on the team, and they lifted everyone. I must mention that Joe Montana is one of the people in the book, and I know that you have an interest with Joe Montana in San Francisco. One of the reasons I have to get back to San Francisco to meet you again in your offices is to meet Joe Montana.

Geoff

Yes. I remember we talked about that. We will make that happen.

Tim N.

I have a series of football or rugby jerseys, and I have to get him to sign-

Geoff

Okay. Let's coordinate that. We can absolutely make that happen.

Tim N.

I would love to do that. That would be super because I have this one lecture on performance, and I have the catch. I go through the catch in great detail, which is really interesting for South Africans who follow rugby, which is of course not American football. I have to explain exactly what the circumstances were and what it meant and why it was such an amazing moment and how perfection comes down to inches. That just epitomizes that moment.

Geoff

Absolutely. Well, I think it just speaks to the sport broadly. I think one part of me is that, who cares about other humans playing some artificial game? But I think it's really a personification of ethic discipline, some of the cultural values that we choose to honor. So I think that's a good analogy. It's a good personification of some of these soft qualities, which is also... I mean, going back to the point around the pneumatic feel of, okay, you sound like the energy in the room, I guess, matched the leaders who had this confidence, this swagger, this inevitability. And that permeated across the entire organization.

Tim N.

In that episode, Winning the World Cup, there was a moment where South Africa could've got knocked out in one of the earlier games. The score was suddenly 20-20. It had been 20-null, and it was suddenly 20-20. The captain realized that the team had lost it, and he called them together. He said, "We didn't come here to lose to this team." He spoke to them because he picked up immediately, and the team just went away and quickly scored the points needed to win the game. They were totally dominant at the finish. Again, the just understanding his colleagues and understanding what was wrong and making the correct diagnosis and initiating the right intervention.

Geoff

Yeah. If there is one takeaway that I can draw from this anecdote, it's that there's some intuition here. Spot the flagging confidence, and when there's that fear, have courage and lift everyone up. Let's push this a little bit more, which I think we all should think about when we have that flagging of courage. Can we have the discipline or willpower to, "Yes, that is happening, but no. We're going to power through this"?

Tim N.

Be brave. And, in fact, that's what the coach told them. Before the final, he said, "Be brave. Just be brave."

Geoff

That is inspiring. I think we discussed quite a bit about how you essentially almost created, or were at least a seminal player in creating, sports science. Going to a second big area that you've contributed towards and are now very vocal about and, I would say, a thought leader in the space of is this notion of low-carb diet for metabolic health, metabolic syndrome. As we all clearly know, and I know our audience is very aware of this, that diabetes rates skyrocketing. Obesity rates skyrocketing. These are unsustainable chronic diseases that essentially, if we do not leave checked, will make society unlivable. If all of us are obese with diabetes with neurological conditions like Alzheimer's, etc., etc., etc., it's just not going to be sustainable. How did you transition or expand your interest from the physiology world into broader health conditions? Was there some trigger point there? Was it just a realization over your career as a doctor, physiologist, realizing... and perhaps your personal journey seeing that a lot of the things that we're working on in exercise physiology can apply to everyone's just daily living, daily health.

Tim N.

I think there are two factors. Firstly, my father died of Type 2 diabetes. I watched him die over 10 years, being treated conventionally. He got all the complications of diabetes, and there I was as a trained medical doctor, not helping him. I couldn't help him. That was very frustrating because I'd been taught that Type 2 diabetes is a reversible condition. It took him 10 years to die from diagnosis to death, and it was just too terrible. I won't even go into his condition when he died. It was appalling. So I watched this process, and ultimately, then, I developed Type 2 diabetes myself and realized I had 10 years to sort the problem out because that was what had taken my father 10 years to die. I realized there were 10 years to sort this thing out, and fortunately, I had a low-carb diet and sorted my problem out relatively quickly and put my Type 2 diabetes in remission.

I've probably had the condition for 12, 13 years now. And, cross fingers, I don't have any complications as yet. I'm hoping I'm going to avoid them. So when I learned that insulin resistance is the most prevalent condition in the world but we don't even teach it in medical school, then I asked the question, why not? What I realized is that 85% of chronic disease is linked to insulin resistance, and the treatment is nutrition. What we do and what we're taught as doctors is we put each of the components of insulin resistance into a separate silo: heart disease, dementia, obesity, hypertension, cancer. We treat them in these different silos, whereas if I was head of a hospital or a medical school, I'd say, "No, no, no. They're all in the same silo. They're all the same disease."

Geoff

Right. The same primal cause.

Tim N.

Exactly. And it's not pharmaceutical interventions. They don't work. They don't help. We've got to sort out the cause. When I was in medical school, we were taught to look for the cause. That doesn't happen anymore. It's now, what's the diagnosis? And here's the road to treatment. And if it doesn't say, "This is how you treat it," you don't treat it that way because then you're in trouble. That's what's motivated me because, as you indicated, we face a tsunami, a disaster heading our way. The obesity/diabetes epidemic is going to destroy medicine, and people don't see it. And we just delay, delay, delay. We have to do something. The answers are relatively simple. It's not rocket science what we have to do.

Geoff

I think everyone, I would say, has good intentions, assuming good faith. I think we would both agree that doctors or researchers that are more of the standard-of-care methodology are not trying to harm people. Academics aren't trying to mislead people when they're publishing about carbohydrates in the exercise physiology world. I think that's something that I think more and more people are starting to realize, is that what are the institutional blocks here where there are actually quite aggressive in blocking novel thought? I mean, this happened in your academic career when you're publishing papers. You were mentioning that if you didn't have this kind of characteristic in publishing for VO2 maximal performance, they would reject the paper or ask you to reanalyze your data.

We're looking at insulin resistance as a root cause, and obviously, I would say in recent years that has more wider acceptance. But standard of care is very, very far from that. Perhaps, just starting at the very, very philosophical or high level there, why is this happening? I think the goals are the same, right? I would think that the doctor on the other side who is arguing for standard of care is saying, "I want to help people, too. This is a tsunami. We should do something about it."

Geoff

What do they have wrong, or what do we have wrong? Someone is wrong. I think good faith... Everyone wants to work on this problem. What's going on here?

Tim N.

I don't want to promote conspiracy theories, but I've looked at it for a long time, and what happened to me was clearly coordinated because I was asking questions that people didn't want to answer. I just happen to think that the pharmaceutical industry and the food industry is so powerful that they control what's being taught at the medical schools. They control what the public are reading. They control the television networks. They control everything. That's the reality. So there's only one message that people are going to get, and that's the one that promotes the industrial diet and the use of pharmaceutical agents. To get past that, it's impossible. You can't do it. The only way we can do it is to train each individual human to question and to experiment with different diets and find out what works for them. Then we slowly work through the doctors because if we can convert doctors, eventually they will realize that this is the way to go.

I think social media has been very important in this because now, today, people will see what works and what doesn't work. I tell my medical students that in 10 years' time, if you're prescribing things that don't work, you won't have any patients because they will have gone onto the internet, and they'll see that doing X, Y, and Z is what works. And there are millions of people reporting that it worked for them. They will try it, and if it works, they won't go back to medicine. So I think with the social media is the only force we have to reverse what's been happening.

Geoff

Would you say you're optimistic? I think the social media, just given what we've seen in our community and the growth and interest in the internet world around ketogenic diets, low-carb diets... Would you say you're optimistic? You have built quite a following on Twitter. We've seen an uptake in interest and discussion. Should we be optimistic? I think conversations like these, where we're nuanced, we're thoughtful, we're unpacking some of the mechanisms of action here, is going to help accelerate this change. I think we see it already where our listenership has been growing quite quickly over the last couple of years. Do you sense a tidal shift?

Tim N.

Absolutely. Just go back five years. No one knew about the banting diet. No one knew about the low-carbohydrate diet. For a period it was the topic of discussion among South Africans. I can't go anywhere without being embraced and thanked every day for saving people's lives. They start crying, and, well, I didn't do anything. I just wrote a book on something. They did it for themselves. And those people... The examples are remarkable. There's a Facebook page, The Banting Seven-Day Meal Plan Facebook Page in Cape Town. 1.5 million people. Three years ago, had no followers. It's got 1.5 million. And it's from every possibly groups of South Africans. Any race, any ethnicity, any age, any gender, they're all there. This start was thought to be for the elite, and it's gone right across the country.

Geoff

Yeah. It's very encouraging.

Tim N.

We're currently working with a domestic servant. So she's quite low on the social scale. She's written her own book on the low-carb diet, a banting book. Isn't that astonishing?

Geoff

It's a movement. Yeah.

Tim N.

She cured her diabetes on the diet. She now helps people like herself.

Geoff

I want to play devil's advocate here for a little bit. So banting, the banting diet, this was a very old diet. Banting, I believe, was the '20s. I don't remember the exact decade, but this is-

Tim N.

1860.

Geoff

'60. Okay. Yeah. Okay. 1860?

Tim N.

Yeah.

Geoff

Okay. Yeah. So this has been around for 150+ years. We had the resurgence of the Atkins diets, I would say... What, '80s? 1980s, 1990s? That was popular for a while. So there's been a couple, I would say, false starts. What's different today versus the initial banting introduction in 1860s, the introduction of Atkins in 1980s? Was it a difference in the specific nuances of how to apply this low-carbohydrate diet, or is there just a much better understanding of how to measure the physiological health markers? What's different today versus the previous false starts?

Tim N.

I think one false start was that the Atkins diet was taking off in the early 2000s, and then he died, sadly. Then that killed it for... People said, "Oh, he died because of X, Y, Z," which wasn't true. His diet didn't kill him. I think what's changed now is that the internet and social media has helped, but I think the science is coming through. And you can tell the science is coming through because the backlash is huge. Industry's backlash and getting published rubbish data, which is absolutely appalling because there's been this onslaught of nonsensical science, which has been published by beta journals in Britain and the United States.

It just shows how scared they are because they're allowing this rubbish to be published. So I think that's what's happening, and let's not forget the company that lives very close to you, Virta Health, which has now shown that we can reverse Type 2 diabetes. That is a massive, massive event. If it hadn't been for Virta Health, we would still be 10 years away from showing that you can reverse Type 2 diabetes. They accelerated the acceptance of it. And the impact of Virta Health... You have to understand the American Diabetes Association has finally, this year, accepted the low-carbohydrate diet can be used in the treatment of diabetes because they couldn't ignore the Virta Health data. So that is a major change because for the last 50 years, they've been promoting high-carbohydrate diets as healthy for diabetics. And how they've got to say, "Actually, a low-carbohydrate diet is acceptable treatment."

Geoff

Right. For folks that might not have seen that paper, this was a two-year study, a one-year study?

Tim N.

Two years. Yeah.

Geoff

Yeah. It's a two-year study of a low-carbohydrate diet, and I think Virta Health has a app to help people go through and coach them through some of these applications. But it's essentially a ketogenic diet. And people essentially got off insulin. People's fasted glucose, fasted insulin would drop. Those are impressive results. Perhaps dive into some of the steel-manning of the other side of the argument. Some might describe that this is... You didn't cure the root cause of carbohydrate intolerance. You just have managed the condition. Did you actually manage Type 2 diabetes, or did you actually cure Type 2 diabetes? For some of the more nuanced discussions, I think it's unquestionable that you are managing this, right? People don't need insulin as much. They can reduce insulin load. But when people reintroduce carbohydrate back into their life, my understanding is that you don't reverse carbohydrate intolerance, necessarily. What are your thoughts there?

Tim N.

Oh, absolutely. It's semantics, but you see, the carbohydrates is the problem. It's like if you're using poison. For us with diabetes, carbohydrates are poison. We can never start eating the poison again. It's going to activate the illness again. So that's the reality. You can't reverse insulin resistance because insulin resistance probably is beneficial in people eating high-fat diets. But it's not beneficial if you're eating a high-carbohydrate diet. Why would insulin resistance be so prevalent as a genetic component of so many populations in the world? Like the Australian aborigines, profoundly insulin resistant. Also the people living in the Pacific Islands, very, very insulin resistant. Why would that be? It has to have some biological reason, some survival value. So I wouldn't want to get rid of my insulin resistance. I just don't want to activate it with a high-carbohydrate diet.

Geoff

Interesting. So maybe this is a protective mechanism. It's sort of the analogy that this is the ambulance on the scene and not necessarily a causal factor, which is interesting. Obviously, I think you're right. Over the last three, five years, this banting diet, this low-carb diet notion has really taken off. And I would say within the last year, carnivore, this notion of only eating meat, has taken off. We've spoken to a number of folks who are advocating that. I've seen you post and discuss that a little bit. Curious to hear your thoughts on carnivore. I've actually experimented with carnivore myself, doing a couple four-week blocks of carnivore. Curious to hear your thoughts on this new, somewhat fringe, perhaps fringe, perhaps interesting diet.

Tim N.

Well, when I first started writing about the high-fat diet, I got letters from people who said they've reversed their Type 2 diabetes. And I said, "It's impossible. I don't believe you." Now, we now accept that, that this diet can reverse Type 2 diabetes. The messages we're getting now is people reversing their autoimmune disease on the carnivore, plant-free diet, plant-based diet that there's no plants in it. I have to say I think that's the next generation of effects, that if I was a scientist today and I was treating people with autoimmune disease, I would like to see what happens if you put them on a diet that was completely free of plants foods and only carnivorous. We're going to have some spectacular results. I don't suggest that it's for everyone, but there will be some spectacular results. Then you can start understanding what's causing autoimmune disease, and there there's a Nobel Prize waiting out there. If I was at the University of California, San Francisco, that's what I'd be doing. If I was a gastroenterologist or leading with other autoimmune diseases, I'd be studying that.

Geoff

I know we have PhD students out there listening, so a Nobel Prize tip here.

Tim N.

Quickest way to the Nobel Prize.

Geoff

What would you say was the hypothesize mechanism of action here? People talked about plants being... Some of the polyphenols are actually triggering immune reaction. What would you hypothesize is in plant material that is not in animal material that is triggering this? What would you specify? What would you hypothesize?

Tim N.

I think that it's the leaky gut syndrome, that there's something in plants, like lectins or other agents that cause the leaky gut to develop. They cause the interest sites to move apart and then allows the bacterial protein to get in. And you cross-react with a protein that comes in which looks like one of your tissues. So you produce an antibody as a response, a cell-based response to that. So you get autoimmune disease. It is so simple, and it's so obviously probably wrong, but it's such an obvious hypothesis to test that that's what I would be doing. I would be looking for leaky gut, reversing the leaky gut and autoimmune disease healing itself.

Geoff

Interesting. Yeah. I think the case studies or the N=1 anecdotes suggest there is some signal here. I think that, to me, is the foundation of science. You see some observation, like here's quite a number of folks who are claiming some autoimmune disease attenuation or some sort of fix with a carnivore diet. There's clearly some signal there. I think that it's premature for folks or professional doctors or researchers to say that is completely wrong. I think the curious mind would say, "Why is that happening? There seems to be some signal here. Can we investigate?" If people do the research and it is wrong, then we will know. But now I think if we just completely ignore it, I think that's unscientific. A fascinating conversation. I'm sure we could go on for a few hours here, but I always want to wrap up with one final question here. And that is, if you had infinite resources, infinite subjects, you could do whatever you want with them, what would be the one trial, the one study that you would want to run? And how would you set that up? You can put people in the metabolic wards. You can put people in the... Whatever you want. What is the Tim Noakes experiment?

Tim N.

One of them would be carnivore diet and its role in autoimmune disease. I think, to me, that would be one of the most spectacular interventions. I think the reversal of dementias with interventions like ketone bodies, that would be really interesting. But I think that the damage has been done to some extent, and I'm not sure how we could go forward there. The other one is cancer. I would love to study cancer on this low-carb diet plus a whole bunch of other supplements. I get feedback from people who use supplementary treatment for cancer, and five years ago, I said they were quacks. It's nonsense. It can't work. But I would like to consider that. In other words, it's not just the ketogenic diet. It's the addition of ketones, and it's the addition of other supplements. I think that that would be really, really interesting. So I would focus on autoimmune disease, and I would focus on cancer because if we can show that we can reverse those two or put those two conditions into remission, that would completely revolutionize medicine.

Geoff

Via a low-carb-diet intervention.

Tim N.

Yeah, off the top of my head. I think that we solved the diabetes issue. Although we continue to research it, I think we've got it. And, finally, because obviously I know your interest, I think the use of ketones in medical conditions needs to be addressed. And, just to finish up, when I was last with you and I was given some of your product, my ketone bodies shot up and my glucose shot down. It was astonishing. I couldn't believe it. So there's a treatment for high glucose. The effect was greater than the drugs I take for controlling my blood glucose.

Geoff

Yeah. Work to be done there. That's a very interesting signal. Absolutely. We're looking into it.

Tim N.

The role of ketones in health is a huge area. But there we go.

Geoff

Professor Tim Noakes, thank you so much for your time. Really a pleasure to have this conversation, and hope to speak to you soon.

Tim N.

Thank you for all the wonderful questions and the chat. I really, really appreciate it. Good luck to you and great success for your company.

Geoff

All right. Cheers. Thank you so much.

Road to Boston: How I Ran a Sub-3-Hour Marathon ft. Michael Brandt

Originally posted on HVMN and authored by Dr. Brianna Stubbs and Zhill Olonan on April 30, 2019

Michael Brandt, who co-founded H.V.M.N. along with Geoffrey Woo, just came back from running the 2019 Boston Marathon. With Boston being Michael’s second ever marathon, everyone on the H.V.M.N. team was especially impressed & happy to hear of his 2:48 finish time.

A sub 3-hour marathon is not an easy feat. On average, Michael was completing each mile in 6 minutes and 24 minutes...for 26 miles straight.

Dr. Brianna Stubbs sits down with Michael to delve into his training structure and the running tips he’s picked up, his experience running the mother of marathons, and what motivates him to run nearly every day.

Transcription

Brianna

Hey Mike, it's great to see you back from Boston. How are you feeling?

Michael B.

Hi, Brianna, it's good to be back. Feeling well.

Brianna

Not too sore.

Michael B.

Not too sore. Although I haven't been able to go for another run just yet. I've been taking it easy.

Brianna

I saw on Strava this morning, or was it yesterday, that you distravad a sauna session that had.

Michael B.

Yes. zero miles at 0.0 miles per hour. I mean, all of the elites, everyone who runs marathons, should take days off afterwards. And they elites, it's their job, their professional, they would do everything that they could to run faster if they could. If it was good for your training to run immediately off of a marathon, they'd be doing it. But everyone takes a break. You owe it to yourself.

Brianna

Oh, I mean, mentally, as well as physically, but, as a scientist, I know all of the destruction that happens inside your body when you put it through this massive strain of running a marathon. So I think, I'm certainly not telling you off for taking a few days to regroup and look after your body, and fuel up, and stretch, and get in the sauna, or all that good stuff that you don't have time to do when you're training. You have to make sure you enjoy this before you crack on with the next thing.

Michael B.

But I do miss it. I think that at a certain ... I trained for a marathon 'cause I like running. It's not like a good riddance feeling. I miss it. It's like, "What do you do when you wake up?" And you can't go run 10 miles.

Brianna

It's funny, 'cause you sent out a message to our group chat this morning asking what you're gonna do with the morning, and I was like, "Well, you'd have a lie in, you could have a nice pot of coffee, you could go and have breakfast with your partner, you could read a book, or catch up on the news, that ..." It's actually, I feel like, especially also having trained really hard for a long period of time, you can think of all these things that you could do, but then the alarm goes off and you need that fix, that little hit of being outside, and moving, and getting everything flowing. So, I empathize, but you do have to make sure that you take some downtime, so that you're super revitalized, ready to go again.

Michael B.

That's right.

Brianna

And try and think of some things that you wouldn't have had time to do when you were training, and you had to get up, and we had to rush down your coffee, or rush down your breakfast, or rush from training to work, 'cause these are precious times when you can just live a bit slower. I mean, we rewound back a couple years when I started working here, and you and I started doing a bit o' training together, I don't think you'd ever run a marathon at that point. You weren't seriously running, but you had done a bit of running back when you were in college. Where were you two years ago, and how did you end up where you are now?

I always had played soccer, and ultimate frisbee, and these sports that were very cardio based. And I was just curious what my benchmark would be for like, "Hey, I'm pretty in shape. Rewinding back to 21, 22 year old me. I'm pretty in shape. How fast can I run a mile?" SO I spent ... It seemed like a long time, but it's only like 10 weeks. I spent 10 weeks. I just ran every day. I'd my friend who is on the Stanford track team, who was a four oh something miler, very fast guy. And he wrote a training plan for me, and got me running every day. And I did it. I broke both five minute mile I ran 4.57 mile, and it was the hardest thing I ever done. But if there was something, I learned what it felt like to be a runner. I think what was cool about it is, over the course of that time, I ramped up to running pretty much every day, maybe six days a week.

And even realizing that that was possible, and then realizing that it takes a certain amount of fitness to even be able to train, you need to train in order to be at a spot where you can train. And, you have to be resilient to be able to run every day, and you need to be able to run every day in order to get in enough training. So, there's a couple o' levels to it I learned at that point. But once I hit my five minute mile, I just went back to playing some Ultimate Frisbee, and going for a run two, three times a week. My big run was around campus, which I look back on it, it was three and a half miles or something. That was my big ... That was what I would do is a big run in college.

Brianna

But I think that's pretty typical of most people out there. The idea of going and running for an hour, or even longer than an hour, that's a significant amount of effort. And I think most people would go out and run for half an hour or 40 minutes, and feel like they'd had a good workout in. I think you're an interesting case in point, because you applied some diligent processes to running the mile as fast as you can. And then, having watched you train for the marathon, you've applied the similar kind of diligent processes. Now, The things that you need to do to run a mile fast is very different to the things that you would need to do to run a marathon for us. And really, anyone who's listening, the general principles of what you're saying, or the kind of approach that's relevant to whatever distance you're trying to run, and as you say, running a marathon isn't right for everyone, and it may be more practical, and more motivating for some people to run shorter distances like five K's. There's so many of those races, you can recover for a bit longer, and actually like myself, I would love to be able to run five K fast. I am not fast.

I can go for a long time, but I'm not fast. So actually, being fast would be a nice challenge for me. I mean, really, I think something that listeners can take away from this is, you have to pick a challenge where you're at, but really, then once you start that, you can just apply thoughtful training processes, and be methodical, and you can still have a good achievement with running. And running is something that everyone can do. You buy shoes and lace up, and then off you go. Most people can do running. So, I think that, and ... I mean, I would like to hand over to you here, 'cause you talk beautifully about how it feels to run, and how the kind of freedom that you get when you're out running first thing in the morning. I think you described in a way that's very motivating. I mean, talk us through how you're feeling when you're running across Crissy fields towards the Golden Gate Bridge, and you're just really getting into your stride.

Michael B.

I think, overly glazing over things to say that every run is beautiful, it's not. I think that I realized is that your memory makes things look very beautiful, but then in that moment they're very, sometimes, very tough. Doing it on the toughest days, there's a way to find some beauty to it. I think that even as you're going through the pain, there's something cool that you can witness about yourself, that you're putting yourself through this. And you have the option to stop, and just go home. No one's watching, no one cares, but then, the fact that you, on your own accord, are deciding to lean into the pain, it's just self generated source of pride and confidence. You can just generate a better sense of feeling good about yourself, and it's free. And all you had to do is buy a pair of shoes, and you can have this profound sense of progress, and self development and then that can easily ... It lends its way into other areas of your life. It's like, you get this confidence in this one area, and then it contributes to your overall confidence. I come to the office and I feel good. I already did something great with the day. The momentum's already there. And the rest of the day keeps going like dominoes from that.

Brianna

How did you fit in all of the training that you needed to do around pretty demanding full time job?

Michael B.

I've structured it though. It's very satisfying to me. Work is very satisfying, gratifying to do. Running is very satisfying, gratifying to do. I don't really care about all the things that I'm not doing. I think some of the best advice I ever had, I think it's from Warren Buffett, he said, "Make a list of the top 25 things you wanna do in your life, and then cross out number six through 25, 'cause those are the biggest distractions." For me, I've been able to find successes with running, with work, and in my close relationships, because, I just don't really cry ... It doesn't really bother me that I can't do all these other things.

There's a million things going on in the world, in every city, and every whatever. There's all these things going on, and you can't really worry about it. And so, I think it took for me a certain level of maturity, to be able to do one thing, or a couple things and put the blinders on, and just just find satisfaction in those instead of wondering what else I could be doing with my time, or what am I missing out on? That FOMO.I don't have any FOMO. I like running, I like working, and that's great for me where I am right now.

Brianna

It sounds like you got to a point where you realized that running was something that you really wanted to invest in. I mean, did that mean that, day to day, you were very, very motivated? Did you struggle with motivation at all, 'cause you sound pretty chipper about it right now? When was it difficult to get up and out of bed?

Michael B.

Yeah, that's a good question, 'cause I always wondered that, "What motivates me?" And, I think the answer is complicated. It changes. Different things motivate me on different days. And even, different things will motivate me on training versus on race day. It's not just one thing. Some days what motivates me is, it's beautiful, and the birds are chirping, and it's a perfect day, and it feels great to run. Your lungs are full of air, you're stretching it out full stride, you're feeling strong and amazing. But that's definitely not every day. But, sometimes that runner's high, or the pursuit of the runner's high is very motivating. Other times it's like, it's not wanting to quit, it's like, it might be horrible to run, you might not wanna run, but it's gonna feel even worse to not run.

There's gonna be a disappointment. There's a sense of indebtedness to your past self. If you've been running every day for the past two months every day, except for planned rest days, you owe it to that past self to get out there and run today. Otherwise, you're letting that past self down. That can be motivated, that sense of, "I don't want that to all be for nothing." It's like compounding, and say, "I don't wanna break the combo streak. If I break the combo streak, then that's all like, it was all for nothing."

Brianna

I definitely think that's super powerful. When I'm racing myself, you think about all of the work that you put in, in training, and you just wanna do yourself justice. But it's the same in training as well. You start to put so much money in the bank with the training bank that you wanna keep putting in those deposits, and not letting it wither away.

Michael B.

One little mind trick ... And running is all about mind tricks. Running is not really about running. Running is about mind tricks. When the last couple o' miles are really hard of a run, you tell yourself that everything else was just a warm up. You're going a 20 mile run, it's like, well, miles one through 18 were just to get you tired, 19 and 20 are really where the real workout is at. And then you can extend that out to life. It's like, you wake up today and you're tired, because you've been running 70, 80 miles for the past week, and you have 70, 80 miles for the week in front of you. Well, you better run today, because the past week you spent making your legs tired, so that on the run today, you'd be getting some really good benefit by running on tired legs. So, if you miss your chance today, and your legs get fresh, you're not gonna be able to get that same training benefit. So you gotta go today.

I just try to have more reasons why I need to run, than why I shouldn't run. And, I just go through them with like, "Is it a beautiful day? No. Maybe it is, maybe it's not. Well, then I need to do it for a sense of what I owe to myself. And if not then, I need to do it just because it's better for training." I just have a list of mental checklist I go through of all the reasons why I should run today.

Brianna

Is it always that complicated or sometimes you just get out and run?

Michael B.

Sometimes you get out and run. I think that one of the things that's really helpful too, I just like to stop the thinking.

Brianna

I find that too. Just-

Michael B.

Just go. I think that having this job is, I have to be in the office at a certain time, which means I have to be out the door at a certain time, which means I have to have eaten breakfast and showered by a certain time, which means I've to be back from my run at a certain time, which means I need to leave the house by a certain time. It's actually funny, 'cause on a weekend, a lot of times I do my long runs on Saturdays, and that run can flow throughout the day. it's something I'm working on, because that can end up consuming the day. Well, I wake, I sleep in, I go to the café, I hang out, I take a phone call. It's 2:00, 3:00, 4:00, 5:00 PM, and I gotta go for this run. But I've been thinking about it all day, and I haven't gone anywhere either, because I haven't done the main thing I need to do today. And so the run can consume the day whereas on weekdays, I just know I need to be out the door at a certain point. There's no negotiating with the alarm clock. It's like, it goes off, I just gotta go. And that simplicity is actually really helpful. I gotta go by a certain point. This isn't some major decision. You know you're running today, just get out there.

Brianna

As part of the build up, can you just describe roughly what a training week would look like? What type of sessions do you do? And roughly, how did that change over the block that you were training? I think it was a 12 week training program, right?

Michael B.

I should start by saying that, even for elite marathon runners, 80% of the miles that they run in training are slower than marathon race pace. You're putting in a lot of miles at first, just getting up, getting comfortable. For me, I was getting up to 80, 90 miles I think, was the peak week for me. And then, towards the middle of the training block, you're working in more speed work. So, you're starting to do some stuff that's faster. You do a couple of 10 K runs, or you'll do intervals where in the middle of a run, you're going at race pace, or you're going faster than race pace, and then all the way through to towards the end, then you're really starting to focus on some speed work. You start doing mile repeats at max effort. And then, a couple weeks before, you start really winding it down, and tapering it, and just saving up all your beans for race day. Maybe another thing that's been obvious is, most runs aren't that hard. Only two or three runs in a week are super hard. You're running every day,...

Brianna

Which is hard.

Michael B.

...which is hard in itself, and it's important to say that, but sometimes, they're very easy, just recovery. You literally go as slow as you want, as long as you go. And then, some days are kinda medium, and then, two or three days will be hard. Some will be hard 'cause they're long, some will be hard 'cause they're faster. But, not every day is the same. Each week has its own variety to it. And if you go too hard on your easy days, then you're not gonna be able to go hard enough on your hard day. So, it's important to respect the rest. Put your effort in when the days are hard, and don't waste it on the days that aren't meant to be hard.

Brianna

How did you monitor your effort? Did you use heart rate monitor, or anything like that?

Michael B.

Yeah, I'm big fan of heart rate monitoring, and the training plan I had went off of heart rate monitoring. So they say, "Do this run at X percent of your maximum heart rate." It's nice to have a smartwatch heart rate monitor, and just know, "I really shouldn't be going above 155.", or whatever it is for that run." On recovery run, it's like, I should really be staying under 120. And being able to keep yourself honest with that is helpful. And sometimes, you gotta pick it up a little bit too, 'cause it might feel like you're going hard, but well, you're actually not going hard.

Brianna

I mean, you're using the guidance from that, and learning how your body feels. And, in this training block, did you have to manage any illness or injury at all, and how does one cope with that?

Michael B.

Yeah, that's a good question. I was talking about it, 'cause I think that it's easy to be overly confident especially when you're newish to running, to where you haven't had any super bad injuries. Thankfully, I haven't, but I'm always aware that it's around the corner, it could happen. When you get to a certain level of any sport, you're just using, reusing the body parts so much you're like, you can injure it. I've had some minor things here or there. I did something, I think I was running on my pair of shoes kind of ran out of steam, and I hadn't replaced yet, and I got a twinge on my ankle, and figured it out, but I had to ramp it down for a week and chill out. And so-

Brianna

Is that frustrating?

Michael B.

It's very frustrating. Yeah, because you wanna be tough, and you wanna ... I mean, you know you need to run, and you wanna throw some toughness at it, but that's not necessarily the answer, and you gotta sometimes lose the battle to win the war. You gotta take a week off, or maybe this marathon training block, maybe it's compromised 'cause you got injured. Thankfully for me, it wasn't that bad, but it was a good sobering wake up call that, don't overdo it, 'cause you wanna be able to run. If you wanna really get good at this, it's a long play. You gotta be doing it for years. And so, it's not worth hurting yourself in a permanent way just 'cause you pushed it too hard.

Brianna

And I think it's challenging because you're ramping up the miles, so that's taking more and more time, and more and more energy, but actually also, as you do that, you need to start doing things like stretching, or making making time to actually look after your body, because it's taking this battering, and that gets more and more important as you have less and less time. So I think that, that's challenging, and I think that you hit the nail on the head, we need to know where to back off in order to salvage long term progress, but also prevention in terms of, as I said, stretching, but for me, one o' the biggest things that affected when my marathon training was chafing and rubbing, and it's like, well, you can do things to prevent that, so that you're not really, really uncomfortable the next time that you go and run, because if you end up with blisters ... I mean, one time, I had a huge ass blister on my big toe, and I had to buy a proper cover for it, because I could hardly walk, let alone run. I think a really important point to take away would be to look after your body.

Michael B.

And I would say, the art of running is the art of injury prevention. 'Cause in a sense, it's like, the running part is easy, but how do you run without getting injured? You have to have, I think, a very high degree of body awareness, which I think you have a much longer history than I do, and I think most people ... I mean, there are very few people who have hit a gold standard in a world stage like you have. And I think that you can't be greedy in the short term outcomes of just trying to run faster today, 'cause you're frustrated at your splits. It's like, back off. You gotta back off a second, and maybe you need to be doing more yoga. Maybe you need to spend some time in the sauna, and maybe the way to run faster is to run slower for a little while, and then the speed will come if you're a little bit more patient with it.

Brianna

You used the sauna, was there anything else that you did during training that helped?

Michael B.

Yeah. I'm a little bit of a fanatic about shoes. I have a lot o' pairs of shoes in rotation when it's ... Some o' the best advice I've gotten is, it's good to have multiple pairs of shoes, so that you're not over-training to just one pair. You don't wanna just have leg muscles that are really well built for this one pair of shoes, and the specific geometry and foam type, and the heel toe drop, and the rise, just for this one pair of shoes. You wanna have strong legs, period, and so you gotta rotate through. And then, there's also just personal preferences. Some people have different issues, or ... It almost gets philosophical.

Brianna

Was things like arch high, and whether you pronate or supernate, so you can get different pairs of shoes that will work with your particular body shape.

Michael B.

There are different pairs of shoes that'll work with you, and then there's different pairs of shoes that you might think it's a good idea to use a really minimal pair of shoes, and you're gonna have to maybe adjust your former, when you use those shoes on that day, you're gonna have to go a little bit slower. And that might be a personal choice that you make, 'cause you read somewhere. You read Born to Run and how the Tarahumara run barefoot, and you know that, that if you subtract all the shoe technology that, your body's gonna do this really natural neutral form. And, that might not be the way you wanna race your marathon, or that might not be the way that you run every single day, but incorporating that into your training might be something that you wanna do.

Brianna

One thing you just touched on a little, that I'd love to hear your take on a little more is form and technique. I know you spent some time watching YouTube videos, and all of that, and personally, my running technique is really bad. I mean, what would be your top three tips, or top three things that you think about that you think it would help people run better?

Michael B.

Yeah. The number one thing I think to run better is cadence. I think that ... And cadence is the number of times your feet hit the ground in a minute. And cadence is really easy to practice, because you can just count it. It's easier than your heart rate even, 'cause you just run for 15 seconds, and you count how many times your feet hit the ground, and you multiply by four. And, general good cadence is around 180, 190 times per minute. And the reason cadence is good, the whole reason that cadence is important is because, if you think about trying to go a certain speed, that speed is gonna be equal to the number of times your foot hits the ground, multiplied by your average stride length. If you hit the ground more times, then you can go the same speed with a shorter stride length. If you hit the ground too little, but you're trying to go fast, if your cadence is slow and you're trying to go fast, I mean, it's gonna really stretch out your stride length. You're gonna be taking too long strides. That's a huge source of injury.

What you never wanna be doing as runner is stretching far out in front o' you, to grab the ground in front of you. That's not the way that the propulsion works. Your foot needs to be hitting the ground right underneath your center of gravity, and then pushing backwards. And, it can feel like you're taking shorter strides than maybe what we're used to, but the way to get comfortable with that is to keep your cadence up, just to keep yourself honest. Make sure that you're you're taking those shorter strides, and not overly reaching. 'Cause again, it's like, when people get shin splints, people get all sorts of issues from over striding, from reaching in front of you. The second you start reaching in front of you with your foot, your foot's hitting the ground before you get there, and then you end up ... It has its breaking effect. Your foot hits the ground, and you're not there yet, and you're at a breaking, and then you end up having like, speed up again once your center of gravity passes over that point o' contact that your foot has made with the ground. And then, what the really good elite people do, is they just have high cadence and high stride length, but they're still all behind you. All of your energy as a runner needs to be going towards forward propulsion. You need to be throwing the ground behind you at all points. Everything else is a waste.

Brianna

Talked a bit about training, and injuries, and form. Let's go back to Boston specifically. How long ago did you qualify for Boston, and how did you qualify? How does that work?

Michael B.

Boston was my second marathon. My first marathon was San Francisco marathon last year, last summer. To qualify for Boston for my age, I'm 30, so to qualify for Boston you need to hit three hours, and that's the highest standard. There's no different ... Men versus women, or different ages, there's different levels o' handicap to make it an equal playing field, but no handicap for being a 30 year old male. And-

Brianna

So that's the fastest qualifying time.

Michael B.

Yeah. That's right. I need to hit three hours. That was my goal. And then, in San Francisco, I had a great day out. I always say, with marathon running, there's really two parts of it. There's, you're mechanic, and you're a pilot, and you spend all the time in training as a mechanic, really building the ship. And every day when you're running, you're building your body. And then, you show up on the start line, and now it's time to pilot this ship. And you have some given level of fitness on that day, and the only so well you can do given that level of fitness, but you can definitely pilot it wrong. You'd have really good fitness, and not be a good pilot on that day.

And, I think that, for San Francisco, I didn't have crazy good fitness. That was my first marathon, and I trained a little off ward, but, I think that it worked well for me, because I probably did it ... Well, I didn't keep overly excited. There were a couple moments where I wanted to go faster, but I held some restraint, and just kept really even in like road ... I think I ran it really well, given what my level of fitness was. If I were to like save and reload that point, I don't think I could have done it that much better.

Brianna

And so, that gave you the qualifying time for Boston, and so you finished that San Francisco looking ahead to Boston. Did you wanna tweak your strategy, or how did you tweak your goals? What was the thought processes there, in to how you're gonna get faster, other than training? You're gonna do the training, but where did you wanna get to?

Michael B.

One part of me is like, "Maybe it's good enough just to keep breaking three hours. It's respectable. Maybe I just wanna break three hours in a bunch o' different marathons. Just keep that standard, and hold that standard for a while and do it in a bunch of fun places." And then part of me was like, "You know what? No." It's like, "I wanna run faster. I wanna know what it feels like." There's something really fun in just letting her rip. Again, if you're a mechanic, it's fun to build the Ferrari, build the best possible vehicle, but then it's also fun on the race day to just let her rip. It's a indescribable feeling that I think a lot o' athletes share, but especially in running, and maybe similar sports where ... It just fun to let her rip. There's just this one thing that you've designed your body for, and you're just taking it out, and you're doing it, and ...

I mean, I know why you don't do that in training ever, 'cause now you're just absolutely demolished. They say not to run fast or long for a month after running a marathon. It's not the most economical training. In training you're doing slower miles, you're doing less miles, but you're doing it every day. But there's something so sublime about just letting her rip. You don't have to worry about, "Am I gonna be sore for this Thursday's intervals, and blah, blah?" It's like, "Nope, just let her rip." Don't get injured. If you get injured, you gotta really tap the brakes, but, your quads hurt, boohoo, let her rip. It's fun to be doing that in your own bias, like riding a motorcycle, but somehow you are the motorcycle. The motorcycle's you.

Brianna

How much faster did you wanna go? What was the new target time?

Michael B.

From San Francisco, I had a 2:55, and then I thought I could do 2:45 in Boston. It's a big step up, and it's big objective time. I ended up doing 2:48 in Boston. I'm not horribly disappointed. I mean, I hit my own personal silver goal, and I hit a standard that's gonna make it a lot easier to qualify I knew in a lot of other marathons. And, I don't know. It's an objectively fast time for a second go around. And I think with my own psychology, now my gold standard just got a little bit faster too.

Brianna

I hear you. You should be really pleased at the time.

Michael B.

If I was to redo it, I would do a full 18 week block. There's just no substitute for time spent in serious training. I think also, I could have probably, if I spent a little longer, I mean, we could have chilled out a little bit, and not been pushing it as hard on each individual run. I might have been over-training a little bit at points, but I think if I stretched it out a little bit, I could've run a little bit slower, a little bit ...

Brianna

You probably would have had time to have micro cycles with the training, like mini peaks as whereas I think maybe with 12 weeks, you've got to keep building until them big taper. I mean, I think, it must be good knowing that there's things that you can try, and do differently, 'cause I think if you felt like you'd really done everything, and left it all out there, and then it might be a bit of a loss as to what you do next. But it sounds like you have some good constructive points for your next one. But, I still wanna talk more about Boston.

Michael B.

Sure.

Brianna

What was the atmosphere like when you got into town?

Michael B.

Boston's really special. This was the 123rd year of Boston. I believe it's America's oldest marathon, and it's always had a competitive standard where you have to hit a certain time to get in, and therefore, it attracts a certain level of crowd. Everyone who's there is a semi serious runner on up, and then a lot of the elites come there too. So, you're running on the same course just right after them, chasing after the Super League guys and girls. Boston's not a huge city, even compared to San Francisco, which is also not a huge city. Boston is not that big, and so when you have all these 30,000 runners, and their families, and they're walking around with their Boston Marathon hoodies, and track jackets, and baseball caps, it really takes over the city. The city goes ... It goes nuts. Marathon Monday, there's no parking anywhere, the whole route is just shut down.

Everyone's excited. I've had some family members who have lived in Boston at different points, and they watch the race, they've cheered on. The whole city just goes crazy. The whole city has the day off, and there's just a lot of fanfare when you're there. The buzz, and you get this sense is like, everyone else there is also run a marathon of marathons, and training, or more. And you're all there for this one day. We could have all stayed home and run 26.2 miles in our whatever, in our own hometown, but we all got on a plane, flew out there, and we're there to all do this thing together. It hangs in the air. There's something special.

Brianna

I think you're right. I think nowadays, in a world where we do so much business remotely, getting people together, like minded people who've all got the same goal for that day, and as you said, you've been on a journey in the run up to, and everyone will have had a different journey, that kind of pregnancy in the atmosphere must be heavy and present, and give you a whole other gear to unlock and really pilot the ship, as fast as you can let it rip, as you kind of been saying. It's pretty inspiring. I mean, how did the race go? I mean, did you get hung up, bit carried away, and go off to hard, or did you pace it? Well, how did the race unfold after all of that training?

Michael B.

Yeah, the race went well, and, I should say, one of the aspects that makes marathoning so tough, and I've said this, is that, you never run the full race distance with the full intensity in training. You're always doing ... You're triangulating out. You're doing more miles over the course of the week. You're doing a couple 10 K races all out, which 10 K is a lot shorter distance. And you'd using that to extrapolate out how well you will pace for the whole marathon, but you never really know, so you show up a day or two before, and especially for someone like me, it's only my second marathon. I've only piloted it a couple o' times, and I'm just wondering, "How fast can I go? Is my goal realistic? If I go out at that speed, am I gonna burn up?" 'Cause there's a certain point where if you try to go a little bit faster, you end up burning exponentially more fuel. You get exponentially tired.

If you try to shave 10 seconds, 20 seconds off a mile, it starts being very expensive to do that. You're gonna crash hard. You don't wanna be going off too fast, but then I thought about it, and said, "You know what? I don't wanna completely miss the opportunity either." If you start out too slow, then you're just giving up at the start line. You're never gonna hit your goal pace. I thought it was reasonable. I could hit my goal. I thought I could do it. And I also just know what it should feel like. I gave myself permission, dialed in, and I said, "You know what? The real goal is to run at ..." I know what it feels like to be running hard, but in a way that I can sustain for a few hours. So I was like, "All right, I'm gonna go off a feel. I'm gonna give myself permission to back off if need to, but I'm gonna hit those splits. I'm not hanging on to it. And if I'm still feeling good around 10, 13 miles then I'm gonna go for broke."

Brianna

That patience aspect of it, it's definitely challenging, when you're excited, and you put so much work into it. That patience to wait until you really push on, but also, as you said nicely that, I permission to go with what you have on the day, and not be too self judgmental, if it's not quite panning out. It's a very interesting mental game. Were there any points where you had to be really on your mental game, where it was maybe a little bit on the edge of going to plan or not? How did that will pan out?

Michael B.

Yeah, there were different challenges at different points. It was generally going well. In the first half, there's a lot o' people around, so you wanna zigzag around them, and you're gonna cover more distance by doing these little micro zigzags to get past people, or do you just slow down a little bit, you end up trying to do something like optimal path that's not too much, but letting you keep your splits. Boston is a really challenging course. It's rolling hills. You'll gain some seconds on this part of the course, you'll lose some seconds on this part of the course. It's really nice to have a smartwatch, and be really comfortable with it, and just know, "Well. I'm five seconds ahead, I'm 10 seconds ahead, I'm five seconds behind." The one number I keep track of is just the cumulative amount I am ahead or behind of my goal. I say, "I'm three seconds ahead on this mile, and then the next mile you're five seconds behind, plus two." And then, you just keep track o' this one number, and you just go, and then ... 'Cause generally, you don't wanna dig too deep of a hole for yourself. Some miles are harder than others, because they're hillier, or whatever, but my philosophy is generally, try to earn it back as quickly as possible. You don't wanna borrow too much from future miles. You don't wanna dig yourself a little hole, and then be like, "Oh, I'll make up for that later." 'Cause, you know what? You're not gonna get any less tired later. I try to keep the bank account at right at even, if not, try to be a little bit ahead. But, you don't wanna be too much ahead. That's always the calculus, like, "Is it here, should I go a little bit faster now, or should I keep my speed, and save some beans for later?"

Brianna

Did you stop falling behind time, and have to deal with that?

Michael B.

Yeah, yeah. I started falling behind time. There's part o' the Boston's metropolitan area, there's a little city called Newton, and there's these four hills and anyone who's run the course knows this well. I think a lot of us have unfinished business in Newton. It's a series of four hills, and they all come back, to back, to back, and they say at mile 18, 19, 20-

Brianna

Is one of these, Heartbreak Hill?

Michael B.

Yeah, it's four hills, the fourth which is called Heartbreak Hill, and ... I mean, it's deceiving, 'cause Boston on the whole is net downhill course. It's about 1000 feet. Sorry, it's about 500 feet net downhill, but within that is ... It's actually 1000 feet downhill, with 500 feet of climb. Nets out to ... It's this nice, minus 500, but you've also got this really chunky plus 500 that's right in the middle. I mean, the downhills not easy either, 'cause downhill just like rips your legs up in a different way. All things being equal, I'd rather run downhill, but it's a little bit different form.

Brianna

It's not easy.

Michael B.

Yeah. If you haven't trained for it, you'd be surprised how much it can tear you up, even though it seems like, "Oh, it's downhill. It's an advantage." It can really tear up your quads if you're not ready for it.

Brianna

What happened to you in Newton?

Michael B.

It just got hard to run. It was just hard to move the legs fast enough, I think. And then you start trying to throw more coal on the fire, then you realize it's not productive, because you're not supposed to be out of breath in mile 18 on a marathon. You're not supposed to be ... There's certain level of exertion you need to control yourself. You can't go there. Just because you're not hitting the splits, you can try to throw a little bit more at it, but it's gonna self destruct if you throw too much at it. If all of a sudden you're outta energy in running this, and keeping your split, feels like an all out effort, then guess what? The next mile, the next, next mile is gonna feel like ... It's not gonna feel very good. You're gonna end up completely falling apart. Again, you gotta give yourself permission. you gotta go off a field like, "We're slipping a little bit here. These hills are not nice, when we're gonna give ourselves permission to slip a little bit, and we're gonna do everything we can to bounce back." I think it's really easy to go on tilts. I think it's really easy, when you start losing a little to start losing a lot. You go 10 seconds off your split, and then it's like, "What's another 10 seconds? What's another 20 seconds? Who cares anymore? I'm not gonna hit my goal."

It's very easy to get discouraged, frustrated, especially if your start was throwing yourself out and getting even more tired and frustrated. But I think you gotta just keep it ... For me, it's just keep it cool, like, "A little bit slower than I woulda liked on this one, but I'm gonna bounce right back on the next one, and try to recover." And I think I knew a little bit from training. I think that's one of the fun things about marathoning is like, you're going at a speed where, in theory, you can recover, even while keeping a pretty decent clip.

Brianna

Someone told me before I ran my first marathon that you were gonna have peaks and troughs, and it was about how you rode the peaks and troughs, and if it felt really rubbish you could realistically get yourself back out the other side as long as you were smart about it. I mean, one thing I think that we haven't talked about yet, that probably plays a huge part in how you get to that point in the race is, fueling and hydration. And I mean, this is me. If this you, I can't believe we haven't talked about this yet. How did you approach the race day nutrition strategy?

Michael B.

I think it even started before race days, is very mindful of my nutrition throughout all of the training. It's been very careful to make sure I'm eating enough, make sure I'm eating high quality stuff, as well as doing certain runs intentionally in a fasted state. Waking up and not having any calories, and going for a run has its own training benefit. And really dependent on what the run was for that day. And without going into too much details, some runs I would go fasted to have that metabolic flexibility. You're running on low glycogen stores, maybe it's a 50 mile midweek run-

Brianna

Woof, 15 miles fasted. That's ...

Michael B.

Well, for me, I'm able to do it, and I know that I'm getting some benefit from doing that, but then, on another run where it's like, "Hey, you really wanna be hitting your numbers. You really want to be spending a certain amount of time at a certain quality, a certain speed.", then by all means, you gotta prepare like it's a race day, like eat well starting 24, even more hours, ahead o' time. Going out with that. When you're really trying to peak your nutrition for running performance, well, it starts a week ahead o' time. I stopped drinking caffeine a week ahead o' time to regain just caffeine sensitivity. I wanted it to work for me on race day. That's no big deal. And then 48 hours ahead o' time, stopped eating vegetables. There's no fiber. The last thing you wanna be doing is having to use the restroom during the race. It's totally solvable. You totally can eliminate the need to have to use bathroom. You just gotta know what to avoid.

No vegetables for 48 hours. Then the day before, just loading up on water and electrolytes. I'm a big fan of these salt tabs you just eat. They help you hold on to the water. It's cool, 'cause you're eating these tabs, they taste kinda nice, and you're drinking water, but you're not really going pee, which is cool. You're holding onto it. And then race day morning, I always have a plain bagel and some coffee. And then, on my way, 45, 30 minutes before the race, I'll have some carb drink. There's a lot o' good ones out there. I think for Boston I had Morton's. I really like it. And then I have a full bottle of ketones at that same time, and just get double loaded up on ketones and carbs. Getting this really good position around half an hour for. And then with me, for Boston, I had six GU packs with me, 100 calories of carbs, a mix of types of sugars, so they can be digested in parallel. And then, I had a little pouch for a bottle o' ketone at the halfway mark.

Brianna

Oh, so you took another one halfway through.

Michael B.

Yeah, which is great. I'm really glad I did that.

Brianna

It's quite hard to do that on the run.

Michael B.

It's hard to do that on the run, but ... I mean, it was fine. I kept in this pouch. I got a nice little pouch that-

Brianna

It's actually for the ketones.

Michael B.

It's like a belt. It's literally special for ketones. It's like a belt that has little pouch on it, and ... I forgot about it. It doesn't feel like anything.

Brianna

It's better to carry your food than be grabbing it from aid stations, 'cause often you don't know what's gonna be on the aid station whether it's gonna agree with you, or whether you miss it or something, and, I think-

Michael B.

Or whether they run out of it. I just wouldn't ... You're paying all this time and money and stuff to be there, I wouldn't-

Brianna

Carry your own stuff.

Michael B.

Yeah, I would definitely carry your own stuff. Use other stuff as last resort. And then I would say, just have a plan. For me, it was, every four miles I was gonna hit it a GU regardless of whether you want to or not. And I always ... I mean, I know well enough to know you gotta do it early and often. So I actually I had a GU, just a loose one that I had right at the start line. And then, every four miles, regardless if you want it ... Four miles, you better not feel tired if you're a marathoner, but you also better have the GU, and you better be grabbing water at every water station.

I think by the time you feel yourself starting to bonk, or you feel thirsty, you're in big trouble. You gotta ... Even four miles in, you're already burning it faster than you're taking it in. You gotta start fighting back against it. Get some carbohydrates in your system. You're already losing water fast than you're taking it in. I don't know. I shouldn't say stop. I'd say grab water at every water station. That'd be my one advice. Don't wait till you're tired or thirsty or anything.

Brianna

It's hard to be taking water on, because each time that you're trying to drink from, they give it to you in cups mostly, and it is difficult to get as much in as you want. I mean, when I run a marathon, my first marathon, I carried a plastic bottle with me for the first hour, so that I knew that I'd have drunk at least that much, but someone gave me a great tip, which was to crush the cup that, they give you, so that you've got just a smaller spout, because always you're trying to drink, and it's going everywhere, and it's very difficult. And that's something that, again, you already get a chance to practice in training, and it's a bit of a faff to be like, "Oh, well, I'm gonna go and I'm gonna get some cups, and I'm gonna run and pick up the cup." I mean, maybe it's worth doing for people, depending on how much effort you wanna put in, but it is...

Michael B.

I've heard of that.

Brianna

...probably not worth trying it for the first time in a full marathon. Maybe at least have done it on a half marathon, or something like that. It sounds like so much thought went into so many of the details of this race, and had been one of the things getting you out of bed every morning since San Francisco. You qualified, and it's on your back of your mind, you're gonna go to Boston. All of that said and done, how did it feel to cross the finish Line?

Michael B.

It felt really gratifying. It was a sweet release, 'cause I was in a lot of pain the last few miles, where it is extremely painful. I couldn't believe it. It's like, in the beginning of the marathon, I was like, "Oh wow, they're just giving these mile markers away." It's like, you look up, and it's, "Oh, wow, mile seven, mile eight, mile nine." Its just happening very quickly. And then towards the end, it's like, "Oh my God, there's three miles between mile 21 and 22." And you know that four miles is nothing, but that last four miles, it stretches on for so long, it's hard to explain. And, there's so many people watching the fanfare along the course, and all Boston marathons is just next level, and especially once you get into the city, you're just a ... It's just a complete sensory overload. Both sides of the street, there's just a line packed with a wall o' people just screaming, and, you pick up the speed a little bit, and the audience is clapping with applause. Everyone's rooting for you.

You clap a little bit above your head, and everyone will just go crazy. Everyone's enjoying sharing the moment with you. They know that you tried really hard to be there, and they ... I think it's inspiring at some level o' the people, and it was just this wave of enthusiasm. It felt very special, I felt very lucky to be there. I knew that, not everyone gets to do that, and I knew that I was there because of, a lot of hard work on my part, but a lot of things that have happened had to happen right along the way for me to even be able to train like this, to even be able to have that time in the morning, and that stability in the home life, and the work life, and all the aspects of my life taken care of so that I'm able to do this activity. It's a lot o' gratitude I felt as I was coming down the homestretch. I really wouldn't be there without lot o' people who have helped in a lot of ways.

Brianna

Sometimes when you get special moments like that, you have to really make a real effort to hold on to them.

Michael B.

Yeah. And I think that's part of why I do it, is the creating o' memories, the deliberate act of doing something so that it will create a good memory, that will create a tent pole moment that you can reflect back on, and be like, "That's who I was when I was 30." I'm not gonna remember every day of the year, but I'll remember that day for a very long time. And that's deliberate. It's like, you're packing all these hours into this one event to make that one day just very, very standout, very special. And, I don't know. We talk a lot about self actualization or hard work being this beautiful thing that you can do, is like, "What is the purpose of life?" Think about, "What even motivates us, us, as a company to make the products that we make, and educate people about them, and get the word out." It's like, we want everyone to be the best version of themselves, and I think in a lot o' ways, in our back o' our own minds, we always think ...

I think a lot of people with a healthy sense of common sense, you think you're special in some way, and you think that you can do great things. So, it's good to actually go out there and do 'em, and get 'em on the permanent record, so that you have something tangible you can look at, and feel good about. And I think that that carries over. 'Cause I feel pretty good at marathoning right now. I mean, there's a lot o' room to grow too. I don't wanna be overconfident, but I feel pretty good at it, and that contributes to this general sense of confidence, which acts as this starter fuel to anything new. I don't know. I'm like, if I took up golf, or took up ... I don't know.

Brianna

Rowing.

Michael B.

Rowing or Japanese calligraphy or anything, there's a certain sense of confidence of, "This is gonna be hard, but I can like stick through it." I have seen myself stick through it. I can look at my own self as a role model. My own self in this other area can be a role model for myself as I approach this new area. I didn't use o know anything about marathoning and I figured it out, so how hard can this whatever new thing be? The answer is, it can be quite hard, but you're gonna be able to figure it out. And it's nice to have those things save, lie, you know you're good, because you did the thing.

Brianna

I mean, I would say that, watching your journey not last two years has been one of the most rewarding things for me as just part of the company, just the diligence, and the way that you've actually achieved the things that you've set out to do. It's been really cool to work with someone who's had that sort of ethos, and just super articulate, and a thoughtful way of keeping everything in context as well. We really appreciate you, everyone here really appreciate you, and I guess, a great question to end on will be, what's next? If we were sitting down in 12 months time, what would you wanna be reflecting on next time?

Michael B.

I've been kinda pendulum swinging between running in triathlon, and I think triathlons a great ... It's funny I called it a break, but it's ...

Brianna

It's okay. I'll do a trade. I'll do the marathon training, you can trade for my Iron Man.

Michael B.

Especially when you Iron Man training in the marathon just a sub part.

Brianna

Run a marathon, then I'll try 112 miles on the bike.

Michael B.

I just wanna work a little bit on my speed. I think it'd be fun to do half marathons for a while.

Brianna

Well, I mean, you run a 1:22 half in the first part of that marathon, so that's like ...

Michael B.

Like a PR for the half marathon.

Brianna

Not slow.

Michael B.

On the front end of that, I think it'd be fun. Also just a little bit less just hours spent training to do a half. You do you faster miles, and you do less of 'em. I think that could be good to maybe get some key half marathons on the map. And then, I mean, I wanna keep running. There's something about it. I wanna run in London, in Berlin, in Tokyo, in Chicago, in New York. There's all the major marathons. One o' the great things about marathon ... This hasn't fit in yet, but tending to answer the questions, but, it's so cool they just shut down all the streets. When else did they do that? In the New York Marathon, you get to run, was it from Queens to Staten Island over the bridge there that's normally only for cars? You can never even walk that path. And in Chicago, there's a half marathon you run on Lakeshore Drive. I think that's one o' the coolest things about these, is like how cool is it sounds just like the streets of Tokyo are shut down, and you're running through it. There's nothing that compares to it. That's I think, a big part of why it's fun to pay and go to the place, and do the things. When else are you gonna run uninterrupted, no car traffic, through that world class city. I think it just sounds like a great way to see a place. I've never been to Berlin. I would love my first trip to Berlin to be just running the marathon there. It sounds really fun.

Brianna

Wow. You made me wanna go out and run. Maybe not quite as far as a marathon right now, but ... I mean, I think, it's just so clear talking to you how much passion for, and energy you have for it. And so, I hope any of the listeners, they can find you on Twitter, and you often post about running. What's your Twitter handle?

Michael B.

It's bdm_tastemakers. And you can find me ... It's easy to find me. I'm easy to reach on H.V.M.N. website, easy to find me.

Brianna

And also on Strava. I mean, if anyone's got any questions, I know I've been involved writing an awful lot of articles about running training, and running nutrition, so all of that's also on our blog. People can check that out as well. And, hopefully, if you've galvanized anyone or inspired anyone, which I'm sure you will have done, they can go out and run their first half marathon, or marathon. And, if anyone does that, we'd love to hear from you.

Michael B.

Absolutely. Love to hear from people.

Brianna

Well, thanks so much, Michael. Happy running.

Michael B.

Thanks, Brianna.

Carb Cycling Guide for Athletes

0,080–that’s how many minutes are in a week. Maintaining a diet through all those minutes, for weeks or months, requires supreme, almost unwavering willpower.

Even The Rock doesn’t do it; his Sunday night cheat meals are stuff of legend, consisting of thousands of calories of his favorite food.

The social side of dieting is tough. It takes dedication to remain unmoved on a diet; happy hour invites, dinners out, work-sponsored lunches–saying “no” to all these are small wins on the battlefield of dieting. For a diet like the ketogenic diet, avoiding carbohydrates can feel like tip-toeing through a minefield of Western, carb-centric eating.

Burn Fat & Build Lean Muscle: Breaking Down Macros & Exercise ft. Menno Henselmans

Originally posted on HVMN and authored by Zhill Olonan and Geoffrey Woo on July 18 2019

A classic, popular fitness goal is achieving 10% body fat.

What if you’re already sitting at an impressive 8% body fat...with the goal of getting to 4% for a contest or photo shoot? What else could one possibly do to get leaner?

This is the level of fitness our guest this week, Menno Henselmans, has expertise in. With a Huffington Post #1 ranked fitness and nutrition website, Menno is a popular bodybuilder, coach, model, and researcher. Similar to our host Geoffrey Woo, Menno is data-driven and applies his background in advanced data analytics to human performance.

In this episode, you'll discover:

  • Important nutritional factors for fat burning and muscle building

  • How an athlete can benefit from intermittent fasting and fat-fueled training training

  • The advantages of exercises that promote freedom of movement

Geoff

Menno, thanks for coming on the H.V.M.N. Podcast.

Menno H.

My pleasure.

Geoff

So a little bit of a time zone shift here. We're hosting from San Francisco and you're in Portugal. I guess to not come off super stereotypical but how's the weather over there? In San Francisco, pretty sunny, pretty smooth, we're just going in the spring here.

Menno H.

Yeah, it's good. The climate in general is really good in Portugal, especially during the spring and autumn. I'm looking over the beach here actually, and it's Labor Day so it's super crowded, everyone's at the beach here.

Geoff

Well thank you for staying inside and doing the podcast on a beach day. So you cover an interesting gamut of human performance, physical training, both training other people and as well as training yourself. Maybe the way to start the conversation here is I would say that the sophistication in terms of diet, nutrition, and exercise protocol has really gotten defined and specific in the last couple years. Let's zoom back in history, how did you first get into the space of training, the science, the physiology? What was your story here?

Menno H.

I've always been into sports. I've done every sport that was available in my region, which isn't that impressive as in the US but in the Netherlands I've done probably 10 sports or so, and at some point I started strength training, which I already started doing in my basement and with my father. I built sort of a homemade squat rack and bought some dumbbells and stuff when I was like 13. Soon after over a couple years I started training in an actual gym, mainly because at volleyball we were also doing strength training, and that sort of stuck but the team fell apart. So I kept doing strength training and I really like that, and everything I do I research. That's basically when I began researching exercise science and nutrition. I naturally have a very data-driven outlook on things, so I try to look for the facts and not just opinions because if you ask 100 different people you get possibly 100 different opinions, and you're no further to an answer than you were before.

I gradually basically as I also matured in development and at school I began researching more of the actual science, and now basically I only read scientific literature, and I don't read anything away from the primary source pretty much. That developed quite gradually. I think everyone goes through phases where the first time you Google something you're not looking for a scientific article because you want a big picture view. You first need some idea of what you're even getting into, what the priorities are, where you're started, and then you can start honing in on specific topics and looking at scientific research. I think I went through the same kind of journey there.

I didn't start off working in fitness but quite quickly realized as a business consultant, which I started working as that it wasn't for me. It was fine but more the career path that my parents wanted of me than what my true passion was. So I start working for myself, started writing about fitness, at first just getting the word out, and basically spreading the truth where I felt there were things that were in fitness, especially because evidence-based fitness wasn't very hot at the time. I felt that I could contribute there, especially with my background now in data analytics and scientific research.

I first just started off writing, and the people started asking me for coaching, and so I started doing online coaching, and then people started asking me for mentoring and how do you get these kind of client results, and I started mentoring people and set up a group where I taught other people how to become PTs and that's now my online personal trainer course, which is an official certification program. It's now expanded into several other languages, and that's still what I do as the two main things basically, the coaching and teaching other people how to be a good online PT or in-person PT as well.

Geoff

Pretty interesting journey, a very organic journey just from a self interest in the people responding to the thoughts you were putting out there. In terms of experimenting and applying to yourself, obviously that's N equals one. Before you teach others you should probably see if you can actually do what you're teaching. Walk me through some of your personal accolades or achievements. Obviously from some of your photos and Instagram, obviously a very lean physique, very cut physique. I don't imagine that that's what you look like when you're a 16 year old a 17, as you're growing up. Talk us through that journey.

Menno H.

Yeah, I've been training since I was basically, like I said, when I was 13 or so or even earlier depending on what you constitute as training, and still am, train basically every day. I've been known for my high frequency training approach for those that really want to maximize muscle hypertrophy. So I'd say I walk the talk. I've done some fitness modeling, I've competed, I'm probably not going to do it in the immediate future because it puts a very heavy strain on what you can do business wise, and how much you can write and research because by the time you're at 4% body fat basically all of your interests narrow down to food, food, and more food. So it's probably not what I'm going to do any time soon but maybe in the future again. I do maintain a six pack year round so I think I'm at a happy, sustainable body fat level. I'm 6'1", a good 90 kilos with abs, so that's a good year round maintainable baseline.

Geoff

That's around 198 pounds, just doing some quick mental calculation.

Menno H.

Yeah, about 200 pounds, so a good ... Yeah, yeah, I said 90 kilos? Yeah, 200 pounds.

Geoff

Yeah.

Menno H.

Yeah.

Geoff

Cool. And then, what were the trigger points? I mean, obviously you don't ... Obviously, was this a slow progression as you just slowly trained more, and more, and more, and then you wanted to go down to 4% body fat? Obviously at 4% body fat, I mean, that is extremely lean. You probably cannot sustain that kind of body fat for too long because one would probably die, but I'm curious to see your journey. You're interested in fitness to 4% body fat in competing. What were some of the key points that led you down that path?

Menno H.

It's a stepwise progression. So basically until age 22 or something, maybe basically college and the like I just lifted and I had some cut and bulk phases and at some point I started doing that, but I just was interested in more muscle growth, and fat loss, but nothing too crazy. I don't think I ever became leaner than 8% or so. I went on surfing holidays so I wanted to be pretty lean for that but that's maybe 8%, so very lean but not contest shape. I started taking things more seriously when I started working as a coach, and at some point I first did modeling because I personally prefer that, creating art if you will, and something you can take home, and of course also something you can use business wise. If you have good shots done then that really helps. So then I started doing some modeling, then also some people liked that so I got some invitations to low level modeling gigs.

As I graduated in my career as a PT and online coach, at some point I also decided that I should really actually compete because even though a photo shoot and a fitness competition are sort of the same physiologically speaking it's not 100% the same experience. So I felt that because I was coaching a lot of people that were competing I felt that I should actually compete as well. So then I competed in US actually, and yeah, that's basically still the level where I'm at. I think I'm honestly pretty much at my natural muscular potential and was before the competition. So, if I now got down to that same body fat level I'd probably look pretty much exactly the same.


There's always some things you can improve and have a little better muscle tension but probably I'd be at a similar level. All in all it's a combination of many, many years of lifting, and probably if you can do it all again and you can look back on everything, all the programs that I followed that didn't work, that's why I say stepwise progression because of all the years I've lifted probably four years of actual progression I'd say is in there, so four years of solid progress all in all and the rest is just finding out what works and where to get there.

Geoff

So that begs the question then. I know that probably a lot of our listeners are very, very specific but perhaps a vast majority of them, maybe I'm over-counting the laziness of my listeners here but just speaking for myself, how about that? When I was going through college people generally know that when you work out that you just probably do some standard lifts, they should do some bench, dead lifts, squats, and maybe do a little bit of cardio, but that's very, very basics of just not becoming totally sedentary. What, in your experience, is the biggest misconceptions of just a very basic style workout versus what has really, really been impactful for you as you were really optimizing your physique?

Menno H.

I think especially in the US if you have those basics down, you train hard, you do the big compound lifts, you're already way ahead of average, especially in the Netherlands for example. I've lifted in over 50 countries by now, so I have some idea of how fitness looks like in various countries. The US is pretty up there. Probably Norway is number one I'd say in terms of general average level of both fitness and fitness knowledge, at least natural, and US is pretty high up there, especially San Francisco, California area.

I think if you have protein, calories, the big compound lifts, that you're actually training hard then you definitely have the basics down. That's pretty much every client I have knows those things, and that gets you through the newbie gates and into some intermediate level of fitness, and that's, for most people, the point where you have to start being more meticulous and taking things into nutrient timings, specifics of exercise selection, complimentary exercises, more niche topics, more advance topics, periodization to really take it to the advanced level and potentially compete, or do something like a photo shoot, or just look awesome in daily life.

Geoff

Yeah, so how about that then? What did your protocol look like to get down to 4% to compete or do a photo shoot? I guess that might be a nice topic as people, especially transition into optimizing for their summer beach body. Okay, they're generally fit, eat generally pretty clean, but I want to optimize in four to eight weeks to really cut down and lean up. There's obviously some strategies on weight loss would be potentially considering a ketogenic diet, fasting, intermittent fasting. What were some of the things that you've seen work with your clients or for yourself, and maybe especially in a competition setting? Obviously I don't think most people are trying to cut down to 4% but curious as here, what it's like to cut down to 8% and then what it's like from eight to four.

Menno H.

Yeah, things definitely change at that point, and it really differs what your long-term goal is because I'm a big proponent if you just want to look good in general of only implementing sustainable methods, and the specific types of strategies you employ are highly individual, for example, intermittent fasting, ketogenic diets. I think those are very valuable tools but definitely not for everyone. So for example, intermittent fasting, there's good research indicating that they work well for certain individuals who are more prone to depressive eating, and also people that have a more active social life at night, especially people that go out a lot because it allows you to have a higher caloric intake of your day at that point of the day, and people that naturally don't have that much of an appetite in the morning, and interval nutrient timing. It also generally works better if you train somewhere in the afternoon or evening because fasted training in the morning and then only eating late at night is generally super optimal for muscle growth.

So those are important considerations for whether you do intermittent fasting. Another thing is activity level, and some research finds that, especially in free living conditions people with higher activity level, if they do intermittent fasting that can result in a lower energy expenditure. So if you have a very active job and by that I mean you are literally on your feet all day, you're just literally moving around, then that might also be a consideration to have an earlier meal, whereas if you're more sedentary you probably have no downsides of intermittent fasting.

Geoff

Yeah, I want to add some color to that because I think those are probably some nuance points there where talking about intermittent fasting and if you have an active lifestyle you want to make sure you're not calorically restricted, right? So intermittent fasting is time restriction versus caloric calorie restriction, so absolutely agree with you that if you are very active, and you intermittent fast, and you are accidentally calorie restricting that is obviously not optimal for maintaining lean muscle mass.

I think in terms of the eating window at a protein sweet spot window after a workout, I think that ... We actually had Brad Schoenfeld, a researcher, looking at some of the studies here, and he was saying that ideally you have protein during and after that workout, but the window is actually pretty broad, but I would also agree with you that if it's morning and then you don't eat until 12 hours later that's probably missing the sweet spot in terms of muscle uptake but one might not necessarily say you need to eat right after working out but the closer is probably more optimal but don't be too stressed out if you have to do something for an hour before you can eat.

Menno H.

Definitely.

Geoff

Would that sound reasonable given your experience?

Menno H.

Yeah, I'm very much in agreement with Brad Schoenfeld, who is a good friend of mine, and someone I highly respect in the exercise science and nutritional fitness. Basically, we both recommend ... not to put words in his mouth but I think we're pretty much in agreement that you probably want to sandwich your workout between about five to six-hour inter meal interval which means that you have workout, you have a meal before, and you have a meal after, and you don't want to let more than six hours or five if you're in more advanced training pass between that meal and that meal which sandwich your workout in the middle. So that's generally a good guideline, and then there's some more finesse in terms of how much protein you want in both of those meals and that depends a bit on if you have many meals before, generally at least .4 gram per kilogram body weight of protein, which is at least 20 grams of high quality protein for most people before and probably double that if not more afterwards, especially if you don't have many more meals afterwards.

Geoff

Yep, cool. So it sounds like ... I didn't want to get too offtrack there but we're talking about cutting to 8%, what are some of the techniques there, and what it's like to get to 8% and then ... I've been approximately that cut but I've never been down to 4% cut. I imagine that it's exponentially harder to go from 20 to 10, and then 10 to eight, and then 8 to 4. Talk us through getting to eight and then getting to four.

Menno H.

Yeah, there are two big things that are different with contest prep than any other cut, and a big psychological factor is that it's not sustainable. So by definition you don't have to ... It's liberating in a sense that you know you don't have to sustain this and therefore you can also employ more aggressive dieting strategies, higher cardio and the like because you know that this is a short-time thing. In terms of actual physiologically what happens, what you need to do to lose fat, it's not different, which generally requires you have to create an energy deficit, and you have to gradually decrease energy intake often throughout contest preparation as your metabolism will decrease unless you put on a very substantial amount of muscle mass during the contest prep but that's generally not likely. So generally you're looking at tapering down your energy intake and you want to be very conservative. So basically the leaner you are the more conservative you have to be with the energy deficit.

There are two things that are extremely important if you want to optimize muscle growth and fat loss, that is your training volume and your energy balance, and the exact sweet spot there can make a very big difference in your results. If you diet too aggressively then if you don't diet aggressively enough you're just wasting time, it's not too bad, but if you diet too aggressively, especially in contest prep, you will just end up losing muscle mass, for example, one study by [inaudible] even found that once people transitioned in high-level athletes, I think they called them elite athletes even, once they went from about a 20% to a 30% deficit, or they compared two groups with those deficits, they actually lost less fat and just more muscle mass.

So in the 20% deficit group they built some muscle and they lost a very sizable amount of fat, so progress was really well. They basically had body recomposition, whereas in the 30% deficit group they lost muscle mass and because of that, probably, and a lower energy expenditure, and worse substrate partitioning, so the P ratio was worse, meaning they lost muscle instead of fat. They were burning off the muscle mass instead of the fat. They actually lost a bit less fat, too. So that actually illustrates how detrimental it can be to be at an excessive energy deficit, but that's at a certain body fat range, for individuals at a certain activity level. So some people can be more aggressive, some people have to be even more restrictive, and generally in contest prep 20% is hefty for most people. So you're looking generally-

Geoff

This is 20% below your basal metabolic rate?

Menno H.

Below maintenance energy intake.

Geoff

Okay.

Menno H.

So maintenance energy intake at that point is very strongly correlated with basal metabolic rate but generally maintenance is a bit higher because you also have exercise induced energy expenditure, and a thermic effect of food on top of that, and just your overall daily activity energy expenditure. So generally in contest preparation you're looking at more, sometimes even a 2.5% energy deficit, somewhere in between that, .5 to 20%, and setting that to the individual is very important, and then things like ketogenic diets-

Geoff

Which is not easy to calculate, right? I mean, even basal metabolic rate is kind of an estimation given your size and body. I mean, unless you're in a metabolic ward testing everything and everything's controlled it's going to be guesstimated. Curious to hear in your experience, are you in a metabolic ward with your clients or are you helping them estimate? It sounds like there has to be some estimation on their daily steps, their daily exercise, calculating all that together, I guess calculating some of their diet, as you mentioned a thermic effect. Certain foods burn off a little bit more ... take more calories to burn than other foods. How are you calculating this? Is it more the back of an envelope estimating or how specific are you getting here?

Menno H.

Very specific. I think the key difference or a key difference I think in my method compared to what many other coaches I'd say do is that I estimate every component of metabolic rate individually. So I estimate someone's thermic effect of food, their activity level, the energy deficit that I want them to be at, I estimate their basal metabolic separately, and the energy expenditure from their workout, from their given workout, and then all of that together to get the total.

So many formulas simplify it, for example, they just say 15 calories per kilogram of body weight, something like that, but then you lose out on a lot of accuracy for a large part of the population. That works well, that kind of formula, and you can see it in research that sometimes you can go with much simpler formula on average but at the individual level that will no longer suffice. So I think it's best to estimate every component individually and then aggregate the total.

That's also, I mean, theoretically what happens if you know what the actual causal drivers of someone's metabolic rate are, which I just enumerate it, thermic effect of food, energy expenditure from exercise and from daily life, basal metabolic rate, which is primarily driven by total [inaudible] mass, then if you have all the components you have a pretty good idea of the total as well. And then afterwards you adjust that based on someone's body composition measures, depending on what someone has available. I'm generally a pretty big component of skinfold calipers if used in and the right way, and weight, and sometimes you have things like dexa scans but usually you have to do with weight and skinfold calipers. Based on that you change things.

It's very important to look at someone's actual rate of progression because sometimes your estimation will still be off and adjust it based on that, based on someone's energy intake, because you have to track that, report that, make sure you're also doing that well, you're using the correct food levels, not like random MyFitness database or MyFitnessPal entries. Based on that you have someone's energy intake, you have a good idea of their energy expenditure, you know what their body composition change is, based on that you have a pretty good idea of what state off energy balance they're in, and then you adjust it to the desired level. I do it on a weekly basis with my clients generally.

Geoff

Yeah, very cool. Definitely that makes sense in terms of getting as specific as you can without sticking these people into a metabolic ward, which is a whole beast in and of itself. Very cool, so in terms of getting from eight to four, it sounds like you're being very rigorous around calculating each component of metabolism, breaking it down, and targeting a window between a 2.5% to 20% deficit, which is pretty hefty if you're going to 20%. That's a pretty big deficit. And so I guess going from ambient training to competition state or photo shoot state, so you're holding a 2.5 to 20% deficit for how long, how long are you making this cut? What else are you doing on top of that?

Menno H.

A long time. My last contest prep, which was basically from good abs to contest shape, was seven months I think, yeah, about seven months, but that was slow because I was originally set to compete with the Brazilian IFBB but the Dutch IFBB wouldn't let me for some reason because they were just lazy with the administrative work actually, and that's why I competed in the US. So for most people six months is a reasonable guideline if you're at a healthy athletic level to begin with, because these days it is very different from before, say 10, 20 years ago when 12 weeks was generally considered contest prep.

They were pretty off season bulky and bodybuilders would be like, "Okay, now I'm going into contest prep," and they do it in 12 weeks. Now, of course pharmaceutical assistance helps a lot, and secondly, standards were just very low. If you look at photos of Arnold Schwarzenegger was generally a massive icon of bodybuilding and you just put any top five classic bodybuilder at a regional event in the US or like European level, Arnold was poor conditioning comparatively speaking. So, that's a major difference. Arnold was like, "Oh, you have some separation in the quads," and now they're like, "Oh, no glute striations, no Pro Cards for you."

Geoff

Yeah, you can say that's definitely happened across almost every single sport in the last recent years versus 20 years ago. The sport has advanced I think a lot due to education and the science and the evidence that's come out on sport science. Absolutely agree with you. So your cut was over seven months. So it sounds like that more of a logistical issue rather than something that you planned ahead of time, but would you say that doing that cut over seven months helped you because you had such a long time to adapt or did it become so long that it just sort of backfired? Curious to hear that experience.

Menno H.

I think I get the same result now in four and a half months.

Geoff

Okay, so you still recommend a longer cut process then?

Menno H.

Yeah, but that's for actual contest prep, right? I have glute striations, so that's a whole different ball game compared to even a photo shoot. A photo shoot now, I could be ready for a photo shoot in eight weeks probably, so like a general fitness photo shoot where you just need six pack and not like glute striations and quads. So it's good to put that into perspective.

Geoff

Okay, and then in terms of ... Okay, so you have these fairly extended cuts. It sounds like one of the broad techniques is looking at getting a metabolic deficit. Are you changing your exercise? I want to talk about a little bit of your exercise protocols and then I want to talk about macronutrients and nutrition protocols. So does your training change? Does the volume change? Does the type of exercises change? For me recently I've been doing a lot more calisthenics and kettlebells versus sort of standard compound lifts. Curious to hear about the trade offs and your thoughts on different forms of exercise.

Menno H.

Not too much changes with my training programs for clients or myself in energy deficit compared to maintenance with one big exception and that's training volume. Generally recovery capacity will be impaired by energy deficit. We have one good study finding that people made better strength development when they cut the volume by I think it was 33%, so that's a suboptimal cut but it still provides a good indication that you want probably a bit of a lower volume. And then if you combine it with contest prep, and especially for me because I have very weak knees and elbows, and there's also big extra factors in terms of prehabilitation, so I need to ... And that's also I think for many bodybuilders why they recommend higher rep ranges before a contest. Some people rationalize that as greater energy expenditure but that will be pretty trivial. The difference in energy expenditure compared to doing sets of eight or 15 is not that large.

So I think the main reason it works for many people is because it's easier on the joints. Generally the lower the intensity the easier it is on the joints. So being injury free, of course, is absolutely paramount. If you get a massive shoulder injury you cannot train your upper body and that happens six weeks out and then you cannot train your upper body for three weeks then you are screwed. That's pretty much your placing down the drain. So it's very important, especially because your recovery capacity is very much impaired, especially as a natural trainee because your anabolic hormone levels will be very low, especially estradiol. Estrogen is often regarded as a hormone that's all bad, like evil. Testosterone is the good hormone and estrogen is bad but actually estrogen has many anti-catabolic functions. It's very good for connective tissue health, and you see that in many research, also in pharmaceuticals. If you cut someone's estrogen levels injury rates skyrocket. So that's something you really have to take into account when you go below the sustainable body fat range.

Geoff

Yeah, that's interesting. That reminds me of research out of Keith Baar's lab who's a physiologist out in UC Davis. He saw some data showing that women in different cycles of their period would have different ACL knee injury rates, and I think it is basically going back to the point that you brought up that estrogen levels impact tissue connectivity strength, and higher and lower, and there's different variation on that strength which is interesting that there's also an application from a bodybuilding perspective on men, but I think in the common world it's too easy to just say testosterone, men, estrogen, women. These are all just physiological hormones that do different impacts on the body. The hormone itself is not classified itself as female or male, right? These are just impact our body in different ways.

Menno H.

Exactly.

Geoff

So sounds like you've increased rep number to reduce load on joints, which makes a lot of sense. Are you still doing compound lifts? What kind of general exercise are you doing? Are you doing calisthenics? Are you doing squats, bench, dead lifts, free weights, machines? Kind of walk us through a little bit of details there.

Menno H.

Everything or at least I get the tools that I want in a certain program. I don't use that many machines generally because ... There are certain machines that are really good like a conversion chest press machine for example offers a big advantage over the barbell bench press in that barbell can never have a convergence movement path. So convergent means your abs go together. Isolateral is also sometimes also what it is called which makes no sense at all bio mechanically, but Hammer Strength, for example, uses that Iso-Lateral Hammer Strength Press. It adds range of motion and majorly improves the resistance curve so that you can get high tension on the pectoralis minor or the pecs throughout a larger range of motion. It's also easier on the elbows, for many people also on the shoulders because the barbell bench press is particularly hard on the bottom position, which is also the most injurious position. So adding things like bands and chains are good ways to improve that or use a convergent chest press machine.

Big compound lifts appear in many of my programs, especially the squat and chin ups, I'm a big fan of ring chin ups in particular, overhead press, also a big fan for those whose shoulders are built for it. Many squat variations, also single-leg squat variations, and ab machine work. I like leg extensions, leg curls, many leg curl variations, body weight variations, many cable exercises. I'm a big fan of cable exercise, many of which I name myself because I want very specific movement angles and resistance curves to overload muscles throughout a large range of motion, and also stimulate the muscles in different parts that are often neglected.

For example, with a biceps curl I use what I call a Bayesian curl which is a cable curl but unlike most people that do cable curls you face away from the machine so the cable station is behind you. The advantage of that is that you have a good stretch in the bottom position, so there's high tension on the biceps then but also high tension on the biceps in full contraction. You can also lean back in the stretch position to emphasize the stretch and lean forward to emphasize full contraction.

Compared to a dumbbell curl that achieves much better mechanical tension, which is the primary driver of muscle growth, over the entire range of motion, whereas a dumbbell is limited by gravity, by gravitational resistance only pulls straight down. So in the middle position of a dumbbell curl, when your arm's at a 90 degree angle compared to the floor there is maximum tension but in full contraction like this. So if you're here and the forearm is vertical there's actually no tension on the biceps, and in the bottom position, when the arm is hanging straight down, there's also no tension on the biceps because the bicep is only exerting force like that, in rotary fashion. So, with clever use of cables and some machines where applicable I like to sort of design my own exercises or get the exact variation I want in a certain program.

Geoff

Yeah, that makes sense. I like how you are nuanced there because I think in a lot of common discussion a lot of people will critique machines as being, "Oh, you're just isolating muscles. You're not building up the supporting smaller muscle groups." But I think you bring up a very good point around the resistance of different zones of muscle, and I think a range of motion is fairly limited if you're just doing some very, very limited exercises and you're weak at the extremities of that motion. I think that's where injury pops up because you're in a very stretched out position. You have no power there because you never train that kind of a set of motion, and that's actually where injuries happen in sport because you're at the limit of your range. You have no power at that range. So incorporating things like cables to strengthen those weak spots essentially is a smart strategy, not even just for bodybuilding but also for injury prevention.

Menno H.

Yeah, definitely. I think for sports and athletes it generally makes a lot of sense to focus on cable and barbell, free weight exercises at least. So machines can actually fulfill that purpose. It's not about whether it's a machine or a cable. It's about the freedom of movement. So there are machines for example with rotary handles that can travel in every direction. That actually provides greater freedom of movement and a better, easier time for the elbows and the wrists for many people compared to say a chin up, which has the wrists fixed because the bar is in a fixed position and now the body is forced into a certain movement pattern that's dictated by that fixed bar position.

Geoff

Yep, yeah. And then the last point I want to bring up is that a lot of people might think that you need to do one rep max to get the max hypertrophy, and it sounds like there's some emerging evidence suggesting that if you do the same amount of effort over more and more repetitions you can get the same amount of hypertrophy. What are your thoughts there? It sounds like there's a consideration also on training versus injury rates. Curious to hear your thoughts on the balance between just going for one rep maxes versus doing a lot of volume. And I guess, what does high volume mean for you? Some people might say eight reps is high volume. When we say high volume, are you meaning 20 reps, 50 reps? How much is high volume?

Menno H.

Yeah, so the question is basically the considerations for the optimal exercise intensity. Exercise intensity is generally defined as percentage of one RM in exercise science. So not to be confused with intensiveness, which is proximity to failure or effort. I would prefer the term relative load but people use intensity so I'll use it as well. Research has found generally, going back to 2002, demonstrating that high rep work actually results in equal hypertrophy as low rep work on sets per set basis if you are equating proximity to failure. So if both groups are training, doing as many reps as they can, then you get the same muscle outgrowth with high and low reps. Many research studies since then have verified that this holds true between the range of four to 30 reps generally.

So it's many other considerations that matter because in the end you sort of get the same mechanical tension on the muscle fibers, and with low reps you get them from the start but with high reps you first build up fatigue and that increases muscle unit recruitment based on the size principle, so the type II fibers or the high threshold multi units with more type II fibers they basically, they kick in later, but in the end you recruit them anyway as long as you're going close to failure.

So for muscle growth you seem to get the same result. There is some controversy of whether the growth is more myofibrillar and contractile with heavy weights whereas it's possibly more sarcoplasmic with light weights, but most research suggests that it's not a big difference. There is some research suggesting it differs for fiber type though, especially when you go all the way up to 30 RM compared to say 90% of one RM. With 90% of one RM you seem to get mostly type II fiber growth, so more fast-twitch muscle fibers, more for explosive sports, have poor endurance but can produce a lot of force and force quickly. The type I fibers are more endurance like, better for sustained combat, and you seem to target those a bit more if you go up to like 30% of one RM or 30 RM, which is roughly the same range depending on the individual.

Geoff

And even within the fiber types there's even like type I-2, type Ia, type Ib, so there's a lot of nuance between the types of muscle fibers that's sort of emerging research as well.

Menno H.

Yeah.

Geoff

Yeah.

Menno H.

So that's a rationale to include both in a training program.

Geoff

Yeah, yeah, I think that's the right level of nuance. I mean, I think, again, it's going back to ... Human physiology's so complicated, and I think it's hard to have one playbook that fits all, right? I think that's why you need experts like yourself walking through, what are your goals, what is your baseline, how do we get you there? Cool. Let's move on to nutrition. I know we talked a little bit ... I think we had a good discussion on exercise protocols and considerations there. Nutrition, macros, bodybuilding has always been at the forefront of nutrition ideas. I think there's been schools of thought where this is like six meals a day, maybe even injecting extra insulin to build up bulk, right, for some of the more pharmaceutically assisted bodybuilders to now in more recent years discussion or thoughts around ketogenic diet, fasting, and all of that. Obviously, roles for different types of goals. What are your thoughts broadly on nutrition and diet? Maybe as an anchor point starting with the cut phase as an initial discussion point.

Menno H.

So compared to bodybuilding coach at least, I'm generally renowned to sort of a low protein, high fat, low carb proponent, but I'd say that's compared to the conventional dogma of very excessively high protein intakes, very high carbohydrate intakes, and almost negligible fat intakes. So actually I'd say my recommendations are quite in line with those of many official health authorities, and from that reference it's the bodybuilders that are fat phobic basically.

I have done a lot of research on protein intake. I think still the most popular article ... No, it's not the most popular article anymore on my site but probably still ranks number one on Google for optimal protein intake and it also participated in the latest meta analysis on protein intake and on a randomized control trial to assess the effects of different protein intakes on muscular recovery. It all points in the same direction, the same direction that's been pointing at since research by Lemon and Tarnopolsky in the '90s, which is 1.6 gram per kilogram per day total protein intake of total body weight suffices, which is .82 gram per pound of body weight, total body weight per day in protein. So for most people it's going to be-

Geoff

Is that for full exercise, or does that change?

Menno H.

That's daily average.

Geoff

Okay.

Menno H.

So it's not taking into account nutrient timing. You probably want to space most of that in your anabolic window so the more post workout periods, but that's like the daily average that should suffice. That's actually the .82 is 1.8 gram per kilogram which is what I generally recommend so I have a bit of a safety margin. Research finds no benefits above 1.6 but I go up to 1.8 based on the same research by Lemon that I mentioned. He added the double sigma it's called, basically an error margin to make sure that even if you are an individual that falls more than two standard deviations away from the normal, what we measure in any research, you're still covered because protein is so important.

Bodybuilders basically take that as more is better and they go up to ludicrously high intakes, and even if you point them to 10 studies, and now I think we literally have over 50 studies supporting this, and they're like, "Yeah, but there's a potential benefit and no harm so go higher." It's true in a sense that there is no harm but there is always a sacrifice in terms of you are giving up another macro nutrient. So if you consider more protein that means you have to consume fewer fats or carbs, and that can itself be detrimental for performance, health, satiety, et cetera, not to mention it's a massive pain in the ass to consume 300 grams of protein every single day.

So I think for a lot of people if you just stick to about 1.8 gram per kilogram or .82 gram per pound as a daily minimum you're covered, and if you go over it it's generally fine as long as you don't dip too low in carbs or fats, but that's pretty much what you need to get, which isn't that hard, right, if you're used to ... Someone who just commented on my Facebook page like, "For standard Indonesian diet that is actually really hard to get that protein intake," but for an American diet where it's easy to add a lot of animal protein sources to the diet it's not that hard.

Geoff

Yeah, sounds very sensible in the sense that the orientation that you have sounds like is the right amount of protein, the right amount of carbohydrate, and then fill the rest with fat, and don't be fat phobic. Does that sound about reasonable?

Menno H.

Yeah, so basically the ratio of carbs to fat, I tailor it to someone's carbohydrate tolerance, which sounds like broscience but there is actually good research showing people with different levels of insulin sensitivity or general carbohydrate tolerance. Insulin sensitivity is by far not the whole story but certain people, for whatever reasons, poor insulin sensitivity, high fasting insulin levels, general poor dysregulated glucose homeostasis-

Geoff

Maybe have pre diabetes and don't even know it, right?

Menno H.

Exactly, yeah. So they respond better to low carbohydrate diets, and it's probably mostly just due to adherence. They have better satiety, they feel better, better moods. They also may be more lethargic if they have a very high carbohydrate intake, and therefore have a lower energy expenditure because they have lower NEAT as it's called, non-exercise activity thermogenesis. They're more lethargic. They don't move as much, even subconsciously. So that determines why some individuals do better on low carb diets, and it seems that based on at least one study there are also people that actually do better on high carb diets or at least highly glycemic diets, but those are, I'd say, very rare and it's within the realm of just being a fluke.

So based on that, if someone's obese it's very likely they are carbohydrate intolerant so then I go higher in fats, and if you want a ketogenic diet then you need to go high in fats and you need to restrict carbohydrates, then my approach is generally a targeted ketogenic diet. Depending on the type of exercise I think that can be perfectly fine for people interested in maximum muscle growth and especially fat loss because carbohydrate requirements really aren't that high, and for pure strength training as many bodybuilders or even exercise scientists will have you believe ... We have a review in process actually at the moment where we look at this and systematically review all the literature on the effects of carbohydrate intake on pure strength training performance, and there is a massive difference with strength training and say tennis because strength training is 20 seconds of exercise, long rest periods, a lot of muscle contractions but half of what you're doing is eccentric muscle action which doesn't have a high energy expenditure. The total volume of work that you do is also far lower.

So if you compare that with something that's mostly concentric, almost constant type activity, and almost all falls in the most glycolytic exercise range intensity, so that's most team sports basically, then you're looking at a completely different level of carbohydrate requirements. So for team sport tennis I would not recommend a ketogenic diet. You know, it can work but it's probably not going to optimize your performance.

Geoff

Because you're doing a lot of anaerobic bursty type movements. You want to be really bursty and anaerobic.

Menno H.

Yeah, and you're going to do that for at least an hour generally. So that's a very high volume of work, which is all reliant on carbohydrates or glycogen and glucose in the body. Pure strength training does not nearly have the same requirements, and especially also the rest between muscle groups is generally much longer. Even if you train full body every time, every single day, which is what I actually do with many clients, which was declared absolute heresy up until a few years ago, you're still looking at 24 hours of recovery. There's a cool study where they looked at how the body can resynthesize glycogen in the complete absence of nutrients, not even just absence of carbohydrates but nutrients in general. They found that within about six hours 75% of glycogen was re-synthesized even while fasted. It's probably mostly because of the Cori cycle.

Geoff

the Cori cycle, I was going to say, yeah. Let's unpack that.

Menno H.

Yeah, it's basically, it's sort of a recycling system whereby the lactate that is produced, not lactic acid but lactate, technical difference, that's produced during exercise is basically recycled back into glucose. That's what the Cori cycle does, and the energy for that can be derived from fatty acids, so mitochondrial respirations. So basically indirectly your body can use the energy you consume from fats to fuel the recycling of glucose to lactate back to glucose and then to lactate again to fuel high intensity anaerobic exercise performance.

If you combine that with the fact that there are still some carbohydrates in the diet, even a ketogenic diet you will still have 50 grams of carbs often. I'm not a proponent of literally trying to go zero carb but it can work for certain people, for certain health effects. So you still have some carbohydrate intake, and there's also the component of the glycerol backbone of triglycerides that you eat in your diet. So the triglycerides that you eat have a glycerol backbone and three fatty acids. The fatty acids can be used by mitochondrial respirations, so basically if there's oxygen the body can burn the fatty acids-

Geoff

Fat oxidation, yep, fax oxidation, yep.

Menno H.

So with the glycerol backbone can actually be converted to glucose. It's normally thought that the contribution of that to total glucose production is very modest but we do not have research on people that have very high fatty acid or very high triglyceride intake and also a very high need to synthesize glucose. So if you combine those two things probably the contribution of that, which remains unexplored, I think can be very substantial, and enough with the Cori cycle and some carbohydrates in the diet that with quite a low carbohydrate intake, especially with a targeted ketogenic diet, with more carbs pre and post workout, five to 10 grams extra generally suffices, can be sufficient to sustain strength training performance at 100% of the level of high carb intake.

Geoff

Absolutely. I think that's a good breakdown on all the processes that the body has in place where carbohydrate is not necessarily a requirement. It's not necessarily an essential nutrient and your body can generate through the Cori cycle, through gluconeogenesis through the glycerol backbone. You could also do some gluconeogenesis through amino acids, right? So you can convert your own carbohydrate. You would not be exogenously taking in enough, but I think there is a question around is that optimal for performance. I think that's where perhaps some keto advocates go a little bit too far. It's clearly possible to revive and be relatively healthy and happy with no carbohydrate but is it optimal for winning an Olympic medal in weight lifting? I think the jury's out for that or tennis as you mentioned as like a team burst anaerobic type sport. Is it optimal for a football player? Potentially not because why limit that extra substrate. I think it's easily overly easy a demonized carbohydrate as completely evil but it is still a very efficient fuel and you might want that for certain sporting applications.

Menno H.

Absolutely.

Geoff

So I think that again is that balance of okay, let's not go too far on either side in terms of understanding what the actual substrate does.

Menno H.

Yeah, and just because it's possible doesn't mean you have to do it. I think there are also a lot of keto haters. You know, there are some keto zealots, but there are, I think, especially in evidence-based science there are probably more keto haters that almost feel attacked when you say, "Keto can work," and they're like, "No, I don't want to do keto, this must be Satan's diet, this is evil, I don't want anything to do with this, this must be terrible." So, you know, it's a tool just like intermittent fasting. That's the way I see it. You can still do high carb. It doesn't change anything that we know about how that diet works. A ketogenic diet, intermittent fasting, they are tools you have in your toolbox just like if someone comes up with a new exercise, you're not like, "Oh, I hate that exercise because I don't want to do it." Well, you don't have to do it, it's extra.

Geoff

Yeah, it's extra. It might be optimal for you but if you don't want to do it you don't need to do it. One thing that I saw you cover recently was exogenous ketones. That's a relatively new potential new macro nutrient that could be added to the mix. Obviously there is a lot of hype from certain people making claims. Maybe let's unpack that a little bit. Obviously at H.V.M.N. we are very deep in the space with our ketone ester drinks, so curious to get your thoughts on has exogenous ketones generally, or ketone esters, entered the bodybuilding world or the community that you work with.

Menno H.

They've certainly entered it but I can't say I'm a big fan of them. Depending on the application, most research has found that they're at least not better than just a high carb or a straight ketogenic diet.

Geoff

For?

Menno H.

Yeah, for appetite management. Appetite management is most promising. Mental performance, physical performance are definitely very underwhelming in terms of research. Health is mostly unexplored, health effects, and that's probably the main reasons why strength athletes take them at least. So in general for all those things research is at best, it's neutral, and some indications even say that it has detrimental effects on, for example, mental well being and performance.

So the desired idea is that you do a non-ketogenic diet, you don't have to bother with restricting your carbohydrate intake, and then you take the ketone drinks, and then you get all the benefits of being in ketosis without actually having to do the work for it. That's the marketing, but in reality it doesn't quite work that way because, well, probably the human body doesn't seem to be that metabolically flexible in that if you have the ketones and the glucose the body's not adapted to handle the ketones as well as you would be in a ketogenic diet. So that's a potential mechanism whereby it could hurt physical performance, and instead of getting the best of both worlds it's just like adding beer to your wine-

Geoff

Right, you're hurting the glycolysis. Yeah, so I would unpack that a little bit in terms of unpacking apart the world of exogenous ketones. So there is a lot of work on ketone salts and then also ketone esters, and I know what you're referring to in terms of neutral on performance or negative on performance bothy physically and cognitively. Those have been focused on actually ketone salts which actually don't get your ketone levels very, very high, but the data that we have on ketone esters is actually pretty positive. So I think I agree with you in the sense that exogenous ketones, I think will have more and more nuance as people start understanding more of the different types of exogenous ketones, right? It's like a starch versus glucose versus maltodextrin versus fructose. They're all a carbohydrate but they have very different functions and roles with the body. I think the nuance between MCT oils, ketone salts, ketone esters will probably have some of that more nuance. So happy to send you some of the papers on the ketone esters specifically that have pretty interesting results for both physical and cognitive performance.

Menno H.

Sure, yeah.

Geoff

Love to get your thoughts on that, but I would agree with the broad point there which is that there is a lot of marketing out there with exogenous ketones melting fat off your body, which is not the case, right? Exogenous ketones are additional calorie sources. So if you're doing everything the same and then dumping extra ketone calories on top it's not some magical substance that breaks the second law of thermodynamics, it's like deletes energy from your system. But I think what you did mention was some of the ghrelin suppression effects from a ketone ester which was done by a research lead. It's interesting to see that there's definitely some interesting data around what drives the appetite suppression effects of a ketogenic diet. Is it the high fat itself or maybe the ketones themselves? So I think a very interesting area of research.

Menno H.

Yeah, I'm looking into potentially citing that. I have much on my plate, but 2020 maybe, study the appetite suppressive effects of exogenous ketones and basically see if it's worth the calories. So I think that is the most promising area of research, and like I say, we don't know the exact mechanisms yet but we do know that exogenous ketones and ketosis itself are very appetite suppressing for most people.

Geoff

Yep, yeah, so if you guys are looking to do a ketone ester intervention we'd be happy to help contribute or be a part of that because I know there's different forms of that. So I think that's a very interesting area of research. Cool, so I think we covered a broad gamut of your history, your PT practice, and then a little bit of the best practices for physical training and nutrition. Where do our listeners follow along and keep track? Obviously you're a wealth of knowledge here.

Menno H.

Mennohenselmans.com, so my name .com has pretty much everything I publish. Most study reviews and the like I do on social media, so especially on Facebook and also Instagram. I'm somewhat active on Twitter but mainly just post article links. So if you're looking to following the latest exercise science and stuff then my social media are best and otherwise if you just want broad applications in the articles then I also have a free email course. It's probably best to get ... The get started basically is an idea of everything I've published.

Geoff

Alright, thanks so much Menno.

Menno H.

Thank you, Geoff.

Heart Rate Zone Training for Performance

Originally posted on HVMN and authored by Brady Holmer on July 24, 2019

Right now, you're probably reading this article, pretty relaxed, functioning at a low resting heart rate—unless you are one of those crazy multi-taskers who can workout and learn simultaneously.

As you start to exercise, your heart beats faster to deliver enough oxygen and fuel to your working muscles. The harder you work, the faster it beats; at the same time your metabolism changes to support the rate of work. Heart rate is a great and highly individual biomarker; there's a strong relationship between heart rate and intensity, and it's easily measured (unlike metabolism). The number of times your heart beats per minute provides a wealth of information—time to take advantage of it.

Get in the Zone

The Big Five HR Zones

Zone 1: Warmup

Zone 2: Easy, Fat Burning Zone

Zone 3: Intermediate Zone, Where the Base is Built

Zone 5: VO2 Max Training

Calculating Heart Rate Zones

Applying the Karvonen formula to calculate HR zones based on desired intensity.

Zone Distribution: How Much Should You Train in Each?

HR Zone Training is Nuanced

As an easy way to quantify energy systems, exercise physiologists and coaches have developed what are now known as heart rate training zones: roughly defined ranges of heart rates (as a percent of max) where certain adaptations can be expected to occur. The goals of any workout can be expressed in terms of a training zone. You use these like a dashboard meters that show what's going on under the hood. With only a little effort, you can start to fine tune your training, targeting specifics to boost your adaptations and get the most bang for your buck...or your heart beat.

Exercise Intensity: The Key to Peak Performance and Health Benefits

Athletes can manipulate three key training variables: frequency, time (or duration), and intensity. Of these, exercise intensity is the most important for performance, weight loss, cardiovascular fitness, and health adaptations to exercise. Intensity is also important for a multitude of other reasons: measuring recovery, planning easy days, formulating a training plan, and meeting fitness goals.

Intensity governs outcome. One classic 1995 study showed the amount of time spent at a vigorous training intensity was associated with lower all-cause mortality.1 Time spent at a low training intensity showed no such correlation. The same may apply to athletes. How hard (or how easy) you spend your training time might be more important than what you spend that time doing.

But how do you know how hard to work?

Using Heart Rate to Measure Training Intensity

Intensity, in relation to exercise, can refer to speed, power, energy expenditure, perceived exertion, percent of lactate threshold, or heart rate. Each of these measures, in their own way, is a proxy for the amount of ATP (energy) our body converts to mechanical energy so we can run, bike, swim, or fight. Intensity measures how much energy we use to perform a certain task.

Heart rate is easy to measure, possibly the best understood and often, the most applied for athletes. HR corresponds perfectly with physiology; when measured during exercise, it can indicate coronary blood flow and myocardial oxygen consumption (how much energy your heart uses).2Additionally, measuring HR is more accessible than power or speed, a more exact measurement than perceived exertion (RPE), and is highly reflective of your status on any one particular day. HR can change with illness, stress, and heck–even thinking about lunch.

Measuring HR during exercise to assess training intensity is the most well accepted and practical method for most athletes. Usually, all it requires is a heart rate monitor.

In addition to exercise intensity, HR can help measure recovery and monitor training load to avoid overtraining. Quantifying your training is just as important as nutrition, recovery, and mental prep. Without quantifying intensity, how do you expect to get better?

Perhaps most importantly, measuring HR during exercise is the best way to individualize training. Exercise based on HR intensity is all relative–your 80% is different than your running buddy’s 80%. Your target heart rate is specific to you, and your training program should be as well.

Get in the Zone

Glancing at a number of “beats per minute” on your heart rate monitor during a workout might not seem to hold any useful information. As a number alone, it doesn’t. What’s important is what your particular HR tells you about objective effort. Where are you in relation to your max capacity? Heart rate can tell you what energy systems you’re using during exercise, and accordingly, what adaptations you’ll get out of the workout.

When we say energy systems, we mean the three main pathways to generate energy during exercise. These are: the phosphagenic (ATP-PCr) system, the glycolytic system, and the oxidative system.

For max-intensity exercise (think, sprints or super heavy lifts that last under 15 seconds), we use the phosphagenic system to generate ATP. For high-intensity efforts lasting under two minutes, the glycolytic (anaerobic) system predominates. For all other aerobic-based efforts over two minutes, the oxidative system makes our energy through mitochondrial respiration. While we always use a combination of these systems, different exercise intensities will rely primarily on one system over the others to use metabolic substrates such as carbohydrates or fats for energy.

Zones were created to give athletes a vague idea of if they’re “in” or “out” of a certain adaptation or recovery window.

The theory goes: craft your training plan around the different zones to create an intelligent training program destined for success.

It is important to know that heart rate training zones are not identical for each athlete. They may vary widely among athletes due to individual variation in physiology, cardiovascular fitness, and even diet. Nor are training zones rigidly defined. Athletes aren’t zone switching robots, neatly switching between different zones. It’s more of a continuum.

Why use zones to train? Athletes don’t (and shouldn’t) train at the same intensity from day to day, workout to workout. Manipulating the most important variable (intensity) is crucial to boost your fitness level over time, avoid a plateau, and stay healthy.

The Big Five HR Zones

Each HR zone serves a specific purpose. Depending on the coach or textbook you consult, zones may differ slightly. Again, these zones are suggestions that correlate fairly well with physiology.

Zone 1: Warmup

Intensity: 50% - 70% HR max

Colloquially described as “very light,” you could probably continuously exercise for 1 - 6 hours in zone one. Light warm-ups, cooldowns, and recovery between sets should take place in this zone, in which fat burning is the primary energy source.

Some athletes might avoid this zone for fear of losing speed, teaching the body slow movements, or otherwise wasting time. But training time spent here is important. Warming up at 60% - 70% of max has been shown to improve range of motion and enhance performance on anaerobic capacity tests compared to a warm-up at 80%.3

This intensity is vital for recovery too. Active recovery between intervals decreases blood lactate concentrations at high anaerobic power outputs compared to passive (i.e. standing) recovery.4 Use zone one for active recovery during workout sessions like high-intensity interval training (HIIT).

Does the thought of an heart-rate revving HIIT session fill you with existential angst? Have no fear. Exercise in a low-intensity zone one also has cardioprotective benefits, promoting clearance of disease-related lipids in the blood vessels and enhancing your ability to burn fat, among other health-enhancing properties.

Zone 2: Easy, Fat Burning Zone

Intensity: 71% - 80% HR max

The bulk of your training should occur in zone two. Here, you should be able to talk with your running buddy; it’s commonly called “conversation pace.” Zone two training should still be fairly relaxed, but not as easy as the zone one. Zone two utilizes the oxidative system to produce energy, churning through a mix of fats and carbohydrates to produce the ATP you need.

Zone two running is sufficient to increase blood circulation and trigger growth hormone responses, but not hard enough to cause considerable muscle damage or deplete your energy or fluid stores rapidly. A longer workout or race (say, two hours or more) in this area however, and you’ll begin to run low on some stored glycogen.

Zone two is great for the majority of your LSD (long, slow distance) runs and your recovery runs on easy days. Running in zone two for recovery might actually enhance adaptations more than your post-run protein shake and nap on the couch. After a highly-damaging and stressful rugby match, players experienced lower levels of psychological stress and higher post-match relaxation when they completed 15 minutes of active recovery at zone two intensity.5

Like zone one, you should be able to pretty much churn away in zone two all day long, and perhaps even longer if using nutrition strategies like exogenous ketones like H.V.M.N. Ketone. H.V.M.N. Ketone boosts blood-ketone levels of beta-hydroxy-butyrate (BHB) and enables the body to use both carbohydrates and ketones for energy–offering superior endurance performance than either used alone. When taken with pre-exercise carbohydrates, beta-hydroxybutyrate (BHB) allowed cyclists to ride 2% - 3% further in a 30-minute time trial than with carbohydrate alone. This is likely due to the combo of high-efficiency ketones that improved muscle efficiency and the presence of ketones sparing muscle carbohydrate stores for the next exercise bout.6

Zone 3: Intermediate Zone, Where the Base is Built

Intensity: 81% - 87% HR max

Zone three is where you enter subjectively moderate exercise intensities but still stay in the aerobic zone. Here, the body is probably using a 50/50 mix of carbohydrates and fats to fuel muscle contraction. The relative percentage depends on your individual metabolism and diet—you can skew your energy use towards fat by following a low carbohydrate, high fat diet.

Some runners and athletes refer to zone three as a “grey zone” between a slow, easy distance and harder interval or race pace workouts. Moderate intensity training (around 85% HR max) has been shown to have a large benefit on V02 max. Zone three is fantastic for building that strong, aerobic endurance base.7
Zone 4: Lactate Threshold Training, Where it Starts to Burn

Intensity: 88% - 93% HR Max

In zone four, we’ve now transitioned to hard running. This heart rate zone corresponds to around lactate threshold; the point where the body begins to anaerobically generate ATP and produce more lactate than it can clear out or use. While still aerobic, in zone four you’ll experience some burning in the legs and shortness of breath.

A majority of longer intervals are performed in zone four, used to improve lower end speed, muscular endurance, and anaerobic threshold.

Tempo runs are an example of workouts completed in zone four; they’re hard, but manageable for a decent duration. Tempo runs are also excellent for teaching your body to tolerate lactic acid.

Training at an intensity around zone four has been shown to be effective for increasing the speed at lactate threshold and improving running performance compared to moderate training in cross country skiers.8Adding one 20-minute session of zone four training to an endurance running program increased enzymes responsible for lactate clearance and improved running economy.9

Zone 5: VO2 Max Training

Intensity: 95% - 100+% HR max

High-intensity interval training (HIIT) is popular for good reason. HIIT is a training regimen with proven benefits above and beyond most other exercise modes and intensities. Be careful; zone five training requires lots of recovery and can’t be done too often without risking overtrainingor injury. In addition, maxing out on effort doesn’t always mean you’ll reach theoretical “maximum” heart rate. Short bursts at max effort may take your breath away, but may not get you into zone 5; still, they still qualify as max training.

In zone five, the body primarily relies on carbohydrate oxidation for exercise and the glycolysis pathway predominates. The intensity of zone five exceeds lactate threshold, requires longer recovery periods during the workout, and sure does hurt.

Athletes training in this zone look to improve muscle strength, high-end speed, and lactate threshold, along with maybe a bit of endurance.

Zone five training typically involves brief, intermittent, all-out efforts (emphasis on brief). An example of the training benefits? Just 30 seconds of “max effort cycling (in zone five) with 60 seconds of recovery over just 14 days improved muscle oxidative capacity, muscle buffering capacity, glycogen content, and exercise performance.10

HIIT consistently is shown to improve V02 max, blood pressure, fasting glucose, body composition parameters, and blood pressure measures in overweight and even healthy populations. Sprint interval training, HIIT’s faster cousin, has been shown to result in increases in peak power output, glycolytic enzyme activity, cycling time trial performance, and carbohydrate oxidation.11,12

If we could train in zone five all of the time with no downside, it would be the way to go. High-intensity exercise is just plain efficient compared to the lower zones. However, polarized training is a necessity for all athletes; so only a small total percent of training should occur in zone five.

Calculating Heart Rate Zones

The first step to finding your heart rate zones is figuring out your maximum heart rate—the fastest speed at which your heart is capable of beating to deliver blood throughout the body.

You can find maximum heart rate several ways. The most accurate is to have a graded exercise test to exhaustion (commonly referred to as a V02 max test) in a lab. But this can be costly.

The second most accurate way is to perform a field test. This involves some type of maximal workout to exhaustion while measuring HR every so often. When maxed out, whatever number your heart rate monitor displays is probably somewhere close to your max.

This one is easy to try. Start by running a mile or two warm-up, then one mile at tempo pace. During the last third of that mile, you should constantly increase speed, then run the final 400m all out. Record your HR afterwards. Athletes of all types can do this one, shortening the distance if necessary.

A less taxing way? Several online calculators exist. Most calculators use a validated prediction equation to calculate estimated max heart rate. One frequently used is:

HR max = 207 - .7 x (age)

After calculating maximum HR, determining HR training zones is easy.

Applying the Karvonen formula to calculate HR zones based on desired intensity.

The Karvonen formula uses a number known as heart rate reserve (HRR) to calculate your exercise heart rate at given intensity (%). HRR is the difference between max and resting heart rate.

HRR = HRmax - HRrest

The Karvonen formula:

Exercise HR = % of target intensity (HRmax - HRrest) + HRrest

To use the Karvonen formula to calculate a HR zone, simply use the upper and lower bounds of a zone to calculate two numbers; this range will be the zone to stay in during the workout.

To calculate desired HR in zone three (81% - 87% HR max) for an athlete with a max HR of 200 and a resting HR of 54:

Exercise HR =

.81(200 - 54) + 54 = 172

.87(200 - 54) + 54 = 181

Zone three for this athlete would occur at a HR of 172 to 181 beats per minute.

Zone Distribution: How Much Should You Train in Each?

Maximizing adaptations to training is the primary goal of any athlete. How much time should you spend training in each target heart rate zone to reach your peak and prevent overtraining?

The answer can be found by taking some advice from the elites.

Successful endurance athletes often follow a polarized training pattern, sometimes referred to as the “80/20 rule” for intensity: about 80% of the total training volume is spent at an intensity below the lactate threshold, and the remaining 20% is distributed between lactate threshold and high-intensity interval training.

Studies on elite cross country skiers revealed 75% of their training sessions were performed below their first ventilatory threshold. Only about 15% - 20% of the sessions were performed as “interval training” bouts.13 High-level marathoners perform very few training sessions at marathon or half-marathon pace (close to lactate threshold), instead devoting a majority of their training volume to logging miles well below lactate threshold.14

Applying this to zone training, this would mean spending about 80% in zones one, two and three. This is observed in athletes who compete in events lasting 3 - 15 minutes–they put emphasis on long slow endurance work as the base for their training. Reserve the remaining ~20% of training for tempo runs, speed work, and HIIT.

Why this distribution? It comes back to adaptations. Low-intensity endurance training likely is best for maximizing muscular adaptations, improving efficiency, and building a strong overall base. Sprinkling in the high-intensity intervals, sprint work, and lactate threshold training meets the need for higher-level signal pathways to prime you for racing and competition.

This pattern also balances the stress-adaptation equation. Too much training at higher heart rate zones could eventually lead to burnout or overtraining.

HR Zone Training is Nuanced

While athletes and coaches may like to view training as workouts to be placed in neat little boxes, this isn't always the easiest thing to do. Using specific zones, interval times, and recovery bouts are simple ways to prescribe training on paper, but doesn’t always translate perfectly.

The same applies to zone training. Heart rate zones are simply “suggestions,” a common formula concocted through years of observation and experimentation by athletes. They correspond well to physiology, but everyone is different.

You might thrive on 80/20, while your nearest competitor might optimize performance on a training program focused on intervals and speed.

As a pervasive example, take the case of two New Zealand world champion rowers who trained together in the same boat, following the same training schedule. Over a four year Olympic cycle, one rower followed the 80/20 rule almost perfectly, performing about ~80% of his training below HR zones 1 - 3, 18% around HR zone 4, and only 1.8% above HR zone 5.

His partner? He spent 67% training in zones 1 - 3, 30% in zone 4, and 2.4% of his training at or above zone 5–utilizing a greater amount of high-intensity training. Different roads to Rio, but the same eventual outcome: a gold medal.15

One final word –your heart rate zone might change on a day-to-day basis, at least from an effort standpoint. Anything that influences heart rate, like stress, lack of recovery, even dehydration, could elevate your heart rate above what might be normal for a given workout. This isn’t a time to freak out or force a pace, but to realize HR zones are here to provide a framework, not a law. Adapt and move on.

Water Fasting: All You Need to Know

Often, we’re told happiness and self-improvement can come only through addition—it’s the consumer culture we live in.

There is nothing inherently wrong about this. Eating healthy food, supplementing, and taking some time to better yourself through exercise or meditation are all additive actions that (hopefully) add something to our lives and help us achieve our best.

But, there may also be another side to human enhancement, one that involves restriction, rather than addition.

Muscle Recovery: Essential to Your Next Workout

The moment every athlete wants to avoid.

POP!

A muscle gives at the gym or on the track, leading to weeks of rehab. Sometimes it’s not even a single moment, but rather, countless hours of overuse that leads a muscle to strain or tear.

To avoid rehab, athletes need to be thinking about pre-hab. Get ahead of an injury before it happens.

Muscle recovery should be part of every training plan (specifically post-workout). But there are multiple strategies athletes can employ that lead to muscle health–even things like diet can impact how your muscles recover. Knowing what to do, and when to do it, can help avoid the injuries that’ll set you back weeks.

Rhodiola Rosea Benefits: A Powerful Adaptogen

Just as some humans are resilient to harsh climates and situations, so too are some types of plants. Interestingly, the qualities of plants that make them robust to mother nature might also make them beneficial for building up strength and resilience in humans who consume them. Those bitter-tasting vegetables are a double-edged sword. Compounds in plants designed to ward off predators are sometimes profoundly beneficial for health when eaten in smaller doses. Lucky for us, people long ago discovered many types of plants that do exactly this.


Couch to Half Marathon Training Guide

Doing something halfway is usually associated with slacker mentality. A wise jedi once said: “Do or do not, there is no try.” That’s why a marathon is the end goal for many runners–it’s the big one. Why would anyone run half the distance? Who cares about the little brother of the sport’s golden child?

Race Day Advice

Far from only half a race, the half marathon is the most popular running event in America, with nearly four times as many finishers as marathons: 1.9 million people finished a half marathon in 2016. Hop off the couch; this is one bandwagon you want to join.

Why You Should Run a Half

The half marathon is a great medium-sized event. Maybe you are looking for challenging race but don’t have the time to dedicate to full-on marathon training. The half is for you. Training for a half marathon may also be a good stepping stone to a full marathon–it provides the base and strength needs to increase distance.

Throughout the half marathon, thousands of spectators line the course. Motivational signs and charity teams and words of encouragement create a tangible buzz. Family and friends and fans create an atmosphere unrepeatable on solo runs. This is what you signed up for, an enjoyable and motivating experience.

If you aren’t motivated by all that, the health benefits of training are a perfect reason to sign up for a half marathon. Endurance exercise training has positive effects on health–improved metabolism, reduced risk for cardiovascular disease, and reduced risk of death from other diseases.1 Your chance of dying from all causes is reduced in proportion to your cardiorespiratory fitness.2 It might even enhance your sexual function.3

Getting Ready to Train

Before starting half marathon training, you should be able to run at least three miles non-stop. Most running coaches and plans suggest this indicates you’re physically capable of running a half marathon. Bonus points if you have previous 5k or 10k experience. Training to finish a half marathon won’t be much different, other than a slight increase in training volume.

Half Marathon Basics

A worthwhile goal for your first half marathon? Finish. Don’t frame your race success on time goals but rather, train with the intent of finishing strong and feeling sturdy throughout the race.

If you completely run yourself into the ground on your first try, this may deter you from wanting to run another long race distance.

Treat yourself to some good running shoes. We don’t recommend going barefoot, but research has shown running in minimalist footwear (4mm heel drop or less) reduces loading rates compared to standard shoes.4 If you go minimalist, gradually ease these into your training routine. Use minimal shoes for shorter and easier runs until you build enough foot strength to transition full-time.

Investing in training and racing gear is a must. Moisture wicking shorts, shirts, and socks can prevent dreaded chafing and help with training in the heat. These fabrics pull sweat away from your body to enable superior cooling. Buying hydration belt or handheld water bottles may be a good investment for your longer training runs.

What it Takes: Half Marathon Physiology

The half marathon distance requires high exercise capacity and takes a toll on the body. Conditioning to build high aerobic capacity is the most important factor for your first half marathon performance. In one study, recreational runners completing a half marathon utilized ~79% of their max aerobic capacity during the race. This is just around “threshold level” for many runners.5

Running at half marathon pace leads to minor lactate accumulation, with one study showing blood lactate concentrations of 5.65mM at the end of the race.5 This is above “steady state” concentration, suggesting runners broke down glycogen anaerobically. A half marathoner maintaining a faster pace at lactate threshold performs best at the distance.

These runners also burned tons of calories–an estimated 1,500 during the entire race. That’s three Big Macs.

A half marathon burns about half of the daily calorie intake of active individuals. Proper fueling before, during, and after the half is important for performance and recovery.

There isn’t a training crystal ball to predict race day performance, but some research indicated running speed during training (and to a lesser extent, body fat and BMI) is related to better performance in men and women.6,7 Makes sense–runners who train harder and have better body composition race faster. But how does this apply to you?

Base Building

Building your base is the most important thing you can do going from couch to half. Essentially, training hopes to create a bigger aerobic engine and increase the strength of running muscles. The base-building phase is mostly made up of easy, long distance runs.

Evidence supports the more you run, the more you refine running gait and ultimately, improve your running economy (RE). Ten weeks of training changes gait variables in runners enough to favorably improve running economy.8 Having a high running economy is important for the half marathon.8 Even small increases in efficiency add up over the race to result in better finish times.

Base building is necessary for injury prevention.

Before transitioning to higher intensity and faster running, it’s necessary to have proper strength and stamina. Fatigued muscles injure more easily. LSD (long, slow distance) training hardens your body to become an endurance monster.

During this phase, it may be valuable for beginner runners to have a professional gait analysis done, or have a family member or running partner video you while running. This can allow you to observe mechanics and notice what might need improvement. Having a strong running form is good for injury prevention and efficient running.

Two or three times per week, integrate form drills into your pre-or-post-run routine. Drilling for just 15 - 20 minutes can build strength, improve form, and increase stride cadence and speed. Butt kicks, high knees, grapevines (also called carioca), slow skipping, hamstring extensions, backwards running, and lateral bounding are all examples of drills used by runners as form work.

New half marathoners can also benefit from time spent on their feet to build general strength and muscular endurance. Integrating low-intensity walking (or run-walking) outside of training is an easy way to log extra miles. Walk home from work, hop off the bus one stop earlier, or take the stairs throughout the day. These may seem trivial, but the time adds up. Think of these activities as cross training.

Speed Work and Tempo Runs

Faster running can be added to a training plan after the 4 - 6 week base-building phase. This allows enough time to develop a bit more speed before the half marathon.

Speed work (intervals) and tempo runs teach your body to maintain efficiency and speed. For this short training block, one speed or tempo session per week suffices.

Begin speed sessions with a one or two-mile warmup, some form drills, plyometrics, and a few strides.

What are strides? They’re fast runs of about 20 seconds at mile pace. Strides improve speed and economy while teaching you to stay comfortable while running fast. They loosen up your legs before a fast running session without tiring you out.

Do the Tempo Run

Run 20 minutes at a pace that’s 20 - 40 seconds slower than 5k race pace. If you don’t have a previous race for reference, running at a comfortably hard pace works. Just make sure you finish feeling like you could keep running, and maintain your effort throughout the entire workout.

After the tempo, do an easy one or two miles as a cool down to prevent blood pooling and muscle soreness.

Performing this tempo or other speed sessions with friends can enhance the enjoyment of the workout. Just make sure you aren’t racing. In a large group of runners with different speeds and experience, things can get competitive, sometimes unnecessarily so.


Easy Does It

In such a short training block, it’s important not to jump into speed work too quickly or too intensely.

Remember, your half marathon will probably be around 80% of your max capacity, so training all-out likely has little benefit. The worst thing you can do is arrive at the starting line feeling fatigued due to training. The goal is to finish training feeling fresh and fit. Only a small amount of speed work will be necessary to achieve this. Make sure to sandwich speed sessions in between two easy runs for freshness and proper recovery.

Race Tune Ups

It is common for many runners to do one or two shorter races in preparation for an upcoming half marathon.

These can be great substitutes for a weekly speed workout or to dial in pace for race day. Doing a race as a workout also makes running fast easier, since you’ll be surrounded by other runners. Sign up for a local 5k or 10k (nothing longer!) about 2 - 3 weeks out from your half marathon. Run this race at your projected half marathon pace to build confidence and help you home in on your race-day pace.

The Long Run

Long runs are the cornerstone of a half marathon training plan. These efforts are essential to build strength and endurance. Rather than a daunting task, see it as a challenge, a worthy dress rehearsal.

For couch to half runners, it’s recommended to build your long run progressively up to at least 10 - 12 miles before race day. This may begin with a weekly 5 - 6 mile run, adding one mile every other week.

Long runs are about confidence and stamina. If you can run 10 - 12 miles, finishing 13.1 is no biggie.

Tackling the Long Run

Don’t worry about pace. The long run is about spending time on your feet and building mental and physical endurance. Schedule a long run in once per week (or every nine days, if you prefer a bit more time in between).

The long run is a great time to practice hydration. If you plan on ingesting fluid or fuels during the race, bring the same formula / brand out on your long run or place them along your route. Become familiar with what it’s like to eat and drink on the run. You don’t want a mishap to ruin your perfect race.

Long runs may be the ideal situation to experiment with your race day nutrition, whether that’s trying out new energy gels, bars or exogenous ketones. Beta-hydroxy-butyrate, the ketone body in H.V.M.N. Ketone, has been shown to enhance endurance exercise performance.

Since long-runs are typically done at a sub-max intensity, athletes will primarily rely on burning a mix of fat and carbohydrates to fuel exercise. Boosting blood levels of D-BHB lowers the need to breakdown carbohydrates during prolonged endurance exercise–it spares glycogen. Athletes who ingested H.V.M.N. Ketone with carbohydrates prior to exercise reduced reliance on muscle glycogen and protein during exercise compared to consuming just carbohydrates.9

Breaking down less glycogen in your long effort means you’ll performer longer and harder, and recover quicker.

H.V.M.N. Ketone can take your long run to the next level.

Ingest one serving of H.V.M.N. Ketone along with your pre-run snack about 30 minutes before heading out the door. Recover with another serving after your run along with your recovery meal to speed up glycogen and protein synthesis.

Cross Training

While running should make up the majority of your couch to half marathon training program, developing strength (strength training) and increasing range of motion (yoga) to ward off injuries is crucial.

This is where cross training comes into your training plan. Cross training involves performing non-specific activities (such as swimming, cycling, elliptical training) to improve your main sport (in this case, running).

Don’t think of cross training as taking away from your running time. New and experienced runners fear that cross training might cause them to lose fitness. Rather, cross training with different activities such as elliptical training and swimming has been shown to maintain and even enhance fitness and performance in runners.10,11

Most cross training activities are much lower impact than running, subjecting the body to less potentially injury-causing impact forces. It’s estimated the prevalence of injuries among runners is anywhere from 37% - 79%, most of these being overuse injuries.12 Cross training provides a break from high-impact running while still boosting fitness.

Include two cross training days per week into your couch to half plan initially. Later on, one of these may be substituted for a shorter run as you boost running strength. It may be a good idea to schedule a cross training workout before and after one of your harder sessions of the week (speed session or long run) to maximize recovery and freshness.

The Body Shop: Staying Healthy

Jumping right into a half marathon training program is ambitious but not unreasonable.

As part of a thoughtful training schedule, ensure recovery is part of your routine. Your body will be adapting to new stress in a short amount of time. With lots of miles on the odometer, constant maintenance is required.

Rest Days

Make one day of the week a complete rest day. This is especially important in the initial 1 - 6 weeks of your base-building phase. This “day of rest” will allow your muscles to regenerate and soak up the replenishing nutrients it may lack as a result of hard training. If you get restless, active recovery in the form of a light walk or hike can stimulate blood flow and get you outside without a demanding workout.

Rest days are about mental and physical recovery.

Stressing about not training or getting out of shape defeats the purpose of this day. One day off won’t sabotage your training. If anything, you’ll get better. Relax, you’ve earned it.

Don’t Forget to Ice (and Sleep)

Sore muscles may be a common theme in your first few weeks of half marathon training.

You’ll be running more than your body is accustomed to, leading to small microtears and damage in the muscles. This causes delayed onset muscle soreness (DOMS),13,14 which is associated with reduced muscle strength and range of motion, reducing performance. Cold water immersion might be effective in reducing the discomfort and performance reduction due to DOMS. Draw yourself a nice relaxing ice bath, sip some hot tea, and recover right.

Regular sleep habits are great for overall mental and physical health. For runners, proper daily shuteye is even more important to promote recovery from training. If you want to make your training stick, sleep is the best way to do it. To promote recovery and restore physiological processes, 7 - 9 hours per night is recommended. 15 Couch to half training may make you want to go right back to the couch post-workout.

Trouble getting to sleep after a hard run? Some athletes experience an anxious feeling if they exercise too close to bed or can’t sleep because they’re too sore. If this occurs, calling on the help of a sleep aid such as H.V.M.N.'s Yawn might allow you to fall asleep quicker and get the high quality rest you need to adapt.

Race Day Advice

As a new runner, if you haven’t heard this phrase yet, you will. “The hay is in the barn.”

This implies that no more work needs to be done. If you’ve trained hard enough and are confident in your abilities, now is the time to rest on your fitness laurels. Nothing left to do now except let your training do the talking.

On race day, don’t go out too hard. While you may have a pace in mind, you’re a first-timer; a finish means a win. From the gun, stick with the pace at which you’ve trained. If you get nearer to the finish line and notice you have some in reserve, open up the last few miles.

Many half marathons have pace accurate groups. If you happen to locate a pace group running right around your goal pace, stick with them and ride it out to the finish.

The most crucial advice? Enjoy the race.

You’ve gone through hard training and accomplished your goal of reaching the start line. Now is time to show off your fitness, and relish in the achievement along with hundreds or thousands of running comrades.

You could be on the couch, but instead, you’re tackling 13.1 well-earned miles. Enjoy each one of them and be proud of the well-oiled machine you’ve become.
