Carbs For Exercise? Let’s Challenge This Idea with Dr. Andrew Koutnik | E211

What we found is that when athletes were either on a ketogenic diet or on a high carb diet, the ketogenic diet did not produce any deterioration in physical performance.

And when we looked at what was fueling these athletes, fat metabolism made up the majority of fuel substrate during this activity at a level of fat oxidation that was higher than any fat levels ever reported in the medical literature.

Some athletes were over 1.8%.

85 grams of fat burn per minute during physical activity.
