What is the optimal fuel strategy for high performance athletes on a Keto diet?
Keto diets are not sustainable for high performance athletes. When athletes train and race at high intense levels of zone 4 and 5 heart rates (above lactate threshold levels), carbs are the first and best fuel source for these efforts.
Does it matter what sport carb drink is ingested for a Keto diet?
Yes, if the carb consumed does not significantly raise blood glucose or insulin levels, then your body will efficiently use a combination of fat, ketones and carbs for energy sources.
In contrast, if a carb significantly raises blood glucose and insulin levels, then your body will be more carb dependent, and not burn fat and ketones efficiently.
