, it doesn’t matter whether you use fat or glycogen to do your workouts. If you did a high intensity workout, and burned all glycogen, the moment you stop your workout, your body gets busy replacing that glycogen and uses predominantly fat to do that.This is incorrect. It is impossible to synthesize carbohydrate out of fat. Your muscle glycogen stores will therefore remain low until you consume sufficient carbohydrate to replete them.
Actually, you’re wrong.
Fats become ketoacids, which go through gluconeogenesis to become glucose, which become glycogen. Your body has the stores to recover you if you rest.
I suggest that you retake your biochemisty course(s). There can be no significant net carbohydrate synthesis from triglycerides (note: glycerol is a carbohydrate). Following depletion of muscle glycogen stores during moderate intensity exercise*, muscle glycogen will remain low until you eat sufficient carbohydrate.
*Obviously if you haven't oxidized the pyruvate that is formed but instead have converted it to lactate, some muscle glycogen resynthesis may occur (especially if you are a rat and not a human).
