Must Listen Podcast For Primal Endurance Athletes

If you are following the guidelines in the Primal Endurance book than you are hopefully eating a low carb high fat diet.  Whether you are just getting started with your diet or are in the middle of your transition to being a fat burning beast, it is always good to hear success stories from people who have already made the transition and are putting it to use.  Able James, AKA Fat Burning Man, recently published a podcast where he interviews Tawnee Prazak, host of Endurance Planet, and successful endurance athlete.  During the podcast Able and Tawnee talk extensively about becoming fat adapted and how it has helped her become successful in her endurance events.  You can listen to the PodCast on YouTube below, view it on iTunes, or download it.

Carbs, Fats, and Aerobic Training

When you first dive into Primal Endurance, you quickly realize that Mark and Brad REQUIRE that you start your race season with an 8-12 week aerobic base building period.  What does this mean and why do this?  First lets start off with the why?

The traditional thought behind training for an endurance event revolves around three main components.  First is logging the right amount of miles.  The thought being the more miles you log the better prepared you are going to be for your endurance event.  In order to have the energy needed to log these huge numbers of miles each week you need to fuel your body.  This brings us to the second component, how you fuel your body.  Again, traditionally this means eating a large number of carbs.  Everything from sugary drinks, cereals, pastas, breads, gels, energy bars, etc.  Just Google how to fuel your body for an endurance event you will likely find a number of suggestions on how to shove as many carbs in your body as possible.  Finally we need some advice as to what workouts to do, and how many miles to run, so we traditionally turn to a training plan to guide us on our journey to finishing our endurance event.

So what is the problem with this approach?  There are a number detailed in the book, but here are the ones that suck out to me.

Lets start out with the typical endurance athletes diet, because everything builds from what you put in your body.

Fueling your body with carbs causes your body to store excess body fat.  When you eat carbs the body transforms them into glucose, but since your body doesn’t need the glucose after you are done with your workout your body stores the glucose as fat for later.  The problem with this is that your body wants to fuel itself with glucose and not fat so the glucose it stored as fat never gets used.  This is why even though you are training hard you may still be carrying around extra fat on your body.  Mark and Brad provide some pretty amazing facts to back this up.  For example…

First of all, we’re not making this stuff up. Dr. Timothy Noakes, long considered the world’s pre-eminent endurance exercise physiologist and whom you’ll read about frequently in this book, cites a study showing that a full 30 percent of the participants in the Cape Town Marathon were classified as overweight or obese. That’s the same overweight/ obese percentage as the world’s population as whole, as reported in the 2013 Global Burden of Disease Study.

In addition, burning carbs is kind of like burning coal.  Burning coal for energy produces a ton of pollutants.  When your body burns carbs it releases free radicals into the body, kind of like the pollutants released when burning coal.  These free radicals wreak havoc on the body causing oxidative damage and accelerating aging.

The final problem with fueling with carbs is that your body has a very limited supply of glucose available for use at any given time.

We are only able to store four to five hundred grams, or sixteen hundred to two thousand calories (highly trained athletes can teach their bodies to store a bit more than the average person) of glycogen in our liver and muscle tissue, and there’s only around five grams of glucose in our bloodstream at any given time.

Once you run out of glucose to burn, you bonk.  This is why endurance athletes that fuel their body with carbs need to refuel with carbs during a race, they essentially run out of fuel if they don’t.

What are the solutions to these problems?  In the book Mark and Brad propose the solution is to fuel your body with fat.  This involves changing a couple of things.  First you need the fat to burn.  However we don’t want to get that fat from carbs because we don’t want to provide the body with the carbs to burn.  Instead we just want to eat more healthy fats while at the same time limiting the carbs we take in.  Mark and Brad suggest you take in anywhere from 50-150 grams of carbs a day.  If you want to have optimal fat loss you should try to stay below 100 grams of carbs a day.  In addition the carbs you take in should be high quality carbs.  Things like fruits, starchy vegetables like sweet potatoes, and quinoa are all good sources of high quality carbs.

The rest of your diet should be composed of meat, fish, foul, eggs, and non-starchy vegetables.  So in summary you want to decrease your carb intake, while at the same time increasing your healthy fat intake.  Everything else should be vegetables, meat, fish, foul, and eggs.food_pyramid_flat_2011sm-1

Next we need to train the body to burn fat instead of glucose.  To do this we need to change the way we are training so we are training at a level where the body prefers fat as fuel over glucose.  This level is different for everyone and it seems to depend on your age.  Luckily there is a formula you can use to give you your fat burning heart rate zone.  That formula was designed by Dr. Phil Mafetone and is extremely easy.  Simply subtract your age from 180 and that is the point at which your body will switch from burning primarily fat to burning glucose.  For example, I am 31 years old so my max heat rate would be 149.  If you stay at or below this heart rate during your training your body will burn more fat than glucose.  By keeping our training at this level we can reprogram our bodies to burn more fat than carbs.  This type of training is called aerobic training.

To most endurance athletes training at or below this heart rate will feel incredibly slow and hard to do, as in hard to stay below.  Mark and Brad stress that you MUST stay below this aerobic threshold or else your body will continue to prefer glucose over fat.

So how long does it take to train your body to prefer fat over glucose?  Mark and Brad suggest you take 8-12 weeks to train at or below your aerobic threshold.  During these 8-12 weeks you should NOT DO ANY anaerobic training.  This includes training above your aerobic heart rate, and any kind of strenuous strength training.

If you do your 8-12 weeks of aerobic training AND switch your diet to include more fat and less carbs your body will begin to prefer to burn fat over glucose and will no longer require you to consume as many carbs as before.  This will help you loose fat and have a more ideal body composition, reduce the release of free radicals into your body, and allow you to race longer without the need to refuel during the race.

You may think that training at this low heart rate and slow pace will somehow hinder your endurance goals.  It is actually the opposite.  By training at this level you will become more aerobically efficient.  This will allow you to continue to become faster even though your heart rate remains the same.  How will this help you during your endurance event?

When you are performing in an endurance event, which heart rate system do you think you use the most, anaerobic or aerobic?  The answer is aerobic, you would not be able to finish such long endurance events if you were using your anaerobic system.  So if you are becoming more aerobically efficient and you are primarily using your aerobic system durning a race than you are going to become faster overall during the race!

This all sounds good, but how does it apply if you are an obstacle course racer?  We will take a look at that in the next blog post!

WELCOME!

So what is this blog all about?

Good question, I am not even sure I know yet, but I think there is a need for it.  Before I get to the point of this blog, let me introduce myself.

My name is Ryan Baxter, a father, husband, IBMer, and amateur obstacle course racer.  If you are looking for my technical content you are in the wrong place.  Head over to my other blog.  If you are here to learn more about being a primal obstacle course racer, than continue on!  I have a passion for three things in life, my lovely family, my career as a software developer, and lastly living a Paleo lifestyle and running obstacle course races.  It is my passion for Paleo and obstacle course raceing that led me to creating this blog.

ME

For the better part of 30 years of my life I was not Paleo, all that changed once I decided to experiment with my diet.  Since about 2008 I had been pretty active, going to gym fairly regularly and exercising.  I thought that this gave me the right to eat however I wanted, so I did.  I ate OK not terrible (or what I thought was terrible at the time) and I was happy with my weight, fitness, and health.  Then in early 2015 after my daughter was born I made the decision to try to “eat better”.  I was not terribly concerned about loosing weight, but instead about putting higher quality foods in my body with the goal of fueling my workouts and possibly getting some definition in my body.  In addition I wanted to be setting a good example for my daughter as she grew.  I made the typical changes to my diet, ate more veggies and fruits, eliminated soda, ate more protein, limited carbs, and started eating only whole grains.  By sticking to these types of changes I started to see results.  I was able to push myself harder during workouts and saw some weight drop and definition in my body.

Becoming A Spartan

After seeing these changes I decided it was time to challenge myself, I wanted to do a Spartan race, so I signed up for a Spartan Sprint at Fenway Park in Boston.  In order to train for the race I decided to start running.  I have never been much of a runner so I started to slowly build up my distance over the Spring and Summer.  In addition to running, I also started doing specific exercises that would help with completing some of the obstacles.  I practiced rope climbing, monkey bars, wall climbs etc.  As I researched more and more about how to train for obstacle course racing in general I was coming across a lot of information about how to eat as well.  I continued to refine my diet and over the course of training for the Spartan Race I decided to limit my carb intake a little more than I was.  I stopped eating bread and pasta almost completely.  With the additional training and changes in my diet I saw further increases in my performance and was able to run distances longer than I ever imagined doing.  I was also able to exercise longer and more frequently than before with pretty good recovery times.

In the fall of 2015 I was able to successfully complete the Fenway Spartan Sprint and needless to say I was hooked on obstacle course racing.  I immediately made the decision that in 2016 I was going to complete the Spartan Trifecta.

Going Paleo

As I began to prepare myself mentally and physically for the journey that awaited me in 2016, I continued to refine my exercise routine and diet.  As I read into different diets and training programs people were using I kept on hearing about this diet called the Paleo diet.  While I found the theory behind the diet sound, I was not ready to give up all grains, and things like beans, and peanut butter.  I still enjoyed many of these things and thought it would be hard to live without them.  Eventually though as I evolved my eating habbits, I found myself eating less and less grains and found plenty of alternatives to things like pasta and bread.  Eventually I was close enough to eating Paleo already I decided to try out the diet and I have never looked back.  This is not to say I don’t “cheat” every once in a while, but 99% of the time I eat Paleo if I can at all help it.

Primal Endurance

One of my favorite health and fitness podcasts to listen too is the Ben Greenfield Podcast.  While I don’t follow every thing Ben says in his blog articles and podcasts, I do find it interesting and a majority of the content useful.  I particularly found his articles and podcasts on eating a low carb high fat diet very intriguing.

Ben’s book, The Low Carb Athlete, is something I suggest you pick up and read if you are at all interested in a low carb high fat diet.  In the book Ben does not necessarily promote a Paleo diet but instead a general diet that is low in carbs high in fat and targets endurance athletes.

One day while listening to Ben’s podcast he interviewed Mark Sisson about a new book he had written called Primal Endurance.

I had heard of Mark before, as he is pretty much a legend in the Paleo community.  However as I listened to his interview with Ben, I realized this book was something that could help me not only train better for my upcoming Spartan Trifecta but also hone in my Paleo diet so I could fuel myself properly for the training and the event itself.  I quickly purchased the book and started reading.

Get To The Point Already

The goal of Primal Endurance is to teach you how to train smarter for endurance events in the most healthy way possible.  Mark and Brad (Mark’s co-author) explain in the book how traditional approaches to training and eating for endurance events are really not healthy.  Traditionally, endurance atheletes fall into a “cronic cardio” approach to training and fuel their body with carbs and sugars.  Both of these things can wreak havoc on your body as is explained in detail in the book.  Instead Mark and Brad suggest you take a much smarter approach to training and follow a high fat low carb Paleo diet for your training.  Finding myself already eating Paleo and feeling like I was already experiencing cronic cardio training I decided to follow the suggestions in the book to train for my upcoming Spartan Trifecta.

This blog is going to serve as a way of documenting what I do and how I train by following the Primal Endurance suggestions and hopefully help others doing the same along the way.
