Ketogenic diets do improve athletic performance

I did not start a ketogenic diet to improve athletic performance.  I started it to protect my brain from dementia.

I agonized for months over how it would affect my training on the bike.  I worked through it and have been sharing for months now how my performance has improved.  I suspected it had a lot to do with my diet, but thanks to a recent study, I have proof that it is definitely in large part due to my ketogenic diet!

The study discussed a clinical trial  conducted in part by 2 familiar names in the low carb world, Jeff S. Volek and Stephen D. Phinney.  20 elite ultra-marathoners and ironman distance triathletes participated in the clinical trial, and were studied to determine the extent of metabolic adaptations.  The results were surprising to some:  Long-term keto-adaptation results in “extraordinarily high rates of fat oxidation.”  The study also found that there was no higher rate of muscle glycogen depletion in the low carb athletes – rather the muscle glycogen utilization and repletion patterns before, during and after a 3 hour run by the participants were similar.

Dave Asprey wrote on Bulletproofexec Blog about this study and it is an excellent read.  He explains what the prior concerns about a low carb diet were as it pertains to performance – past studies concluded an athlete would “top out” at 10% of energy provided from fat and the rest would have to come from glucose stored in your liver and muscles.  The belief was that if you followed a low carb diet and could only access 10% of your fat for energy, then you would end up breaking down muscles for energy (where glucose is stored).  Others believed you could harm your liver by depleting it of glycogen while following a low carb, high fat diet while engaging in intense physical workouts.

Both Jonathan and I have worried about glycogen depletion and have used products like UCAN’s SuperStarch to try and avoid that.  I’ll need to digest this study a little more, but at first read the results seem be telling us we don’t need to worry about glycogen depletion.  Definitely good news for us and other endurance athletes!

Why I’ll be eating dirt and showering less

I’ve been on a mission for the last few months to figure out why, despite eating pretty much the same foods as I did for the last 10 months, my stomach has been in constant turmoil.  I noticed the changes beginning in January, but chalked it up to not being as diligent with my food through the holidays.  I have struggled with Irritable Bowel Syndrome since my teen years, but it had been relatively quiet when I started the ketogenic diet last February.

My stomach issues have persisted since January – bloating, gas, stomach pain…and I was eating the same food I had been eating the previous year.  It came to a head recently when the stomach pain was accompanied by an intense headache so severe I couldn’t sit at my computer and work.

I have also developed pretty severe pain in the first knuckle on my right hand that, despite accupuncture, icing, and rest, continues to worsen, leading me to fear it is arthritis.  It realized it was time to get more focused on what was going on inside my body that was creating these symptoms.

I started looking more seriously into what could be causing my stomach issues.  I did not think my hand pain was related, and it may not be – I was planning to see a regular doctor about it instead and still will if the symptoms don’t lessen.  I had already started eliminating certain types of food, like sugar alcohols, but my symptoms weren’t going away.  I won’t bore you with all the details, but my research led me to a book by Dr. Josh Axe, “Eat Dirt: Why Leaky Gut May Be the Root Cause of Your Problems and 5 Surprising Steps to Cure It.”

I was shocked at the symptoms listed that have been shown to be the result of a leaky gut:  Tired and sluggish, frequent indigestion, heartburn, bloating and gas, brain fog, cloudy memory, headaches, changes in skin like dark circles, eczema, psoriasis and acne, and joint pain.  These can turn into far more serious issues like chronic fatigue, adrenal exhaustion, arthritis, inflammatory bowel disease and more, and I have experienced most of those symptoms the last few months.  I have complained to my husband numerous times about persistent acne.  I never had a problem with it when I was younger, and cannot understand why I’d have breakouts now.

It turns out the problem may be in my gut and the fact that the “good” bacteria is being overridden by bad bacteria.  Apparently,  we aren’t what we eat, but rather what our food eats.  And, according to Dr. Axe, we just might be too clean – antibacterial “everything” we now use is killing the good bacteria in our gut.  Ingesting a little bit of dirt from organically grown fruits and vegetables certainly won’t kill us, and in fact, will make us healthier.  He also suggests that it is not necessary for us to shower every day (unless having worked out) and that we would be healthier if we didn’t.  There’s much more to the book than this, including some fascinating research on the effect of outside toxins on our bodies, and of course how to treat and heal your gut.

Thankfully, many of the food recommendations are very close to the ketogenic diet we already follow.  But it appears I have to give up my love affair with cheese (or at least most types of cheese).  And I have to learn to get used to drinking apple cider vinegar on a regular basis.  Both are a struggle.  But on the positive side, I was motivated to finally make bone broth soup.  I never thought I would be paying good money for organic, grass-fed beef bones, but I have done it.  It has been simmering for about 30 hours, and has another 12 or so to go.  I’ve known this is a wonder food for a while, but until now I just didn’t have the proper motivation to make it or eat it consistently.

I encourage you to read the book or the plethora of information available online about leaky gut and see if you might benefit from some of the supplements and food recommendations in the book.  I figure I have nothing to lose but a whole lot to gain if I make a few small changes and they work.  But I do promise to continue showering…
