Ketosis and Fat Burning is it Right for You?
Today we have a special episode with two medical doctors who are also avid runners and personally advocate for the fat burning way of eating that creates ketosis and, for many people, fat loss and increased performance as a runner.
We’re talking with Dr. Mark Cucuzzella and Art Zemach, who have both interviewed on this podcast before. This is an informative and interesting topic for many of you, presented from professionals who know the subject intimately. Both doctors have used the Low Carb / High Fat concept in their own running and have offered to speak professionally as well as personally to the pros and cons of ketosis as a nutritional concept for runners.
I consider myself a #realfood
person, prone to #lchf
but too strict. This episode is very interesting and the one thing I most appreciate is when Dr. Cucuzzella explains why one can eat some carbs without problem (not in exccess and not "carboloading") when doing endurance sports, and it is because how diferent our body procceses carbs when running if you are somehow fat adapted.
It takes some minutes (20-30') to glucose start using this NON-dependent insulin biochemical pathway. In such time, we #LCHF
athletes have RELATIVE-low insulin levels and takes some time to our bodies start using this alternative route while burning fat. He describes this moment as the moment when you start "feeling good" and fresh after some inicial struggle at the start of a long run.
Then, our bodies are burning fat at the normal rate and have a direct supply of glucose to the muscles.
THIS IS WHAT I'VE UNDERSTOOD.
The worst thing an athlete can do is right at the starting line have a bunch of simple carbohydrate because if your insulin is up, your body can’t use fat as fuel. So you’ve just vandalized your whole race strategy by throwing some Gatorade in at the start. It takes about 30 minutes for your fat engine to really get going.” – Dr. Mark Cucuzzella
