Carb Refeed is one of the predominant terms used against ketogenic athletes, people say you need carb to do endurance or any kind of exercise, but is this true?

Do you Need to Carb up on a ketogenic diet? The answer is NO! In this study 22 elite athletes on either a high carb diet (50 % of calories) or a ketogenic diet (Carbs only 5-10 % of calories) performed a long duration endurance event meant to deplete muscle carbohydrate stores (glycogen).

After exercise subjects in the keto group received a high fat low carb shake, while the carb group received a high carb, low fat drink.

As you can see muscle glycogen / carb stores were the same in both groups at the beginning. And amazingly the low carb athletes replenished carb stores equally as fast as the high carb group following exercise! This brings into question the need to carb up on the weekends when ketogenic dieting.
