So in different phrases, the physique loses muscle. However this isn’t precisely 100% correct: The physique shops glucose within the type of glycogen (saved type of sugar) within the liver and muscle groups. Over the course of the evening, the physique’s ranges of insulin (which helps cells take in sugar and inhibit fats loss) and liver glycogen lower. However the physique nonetheless has muscle glycogen shops. So whenever you begin your morning run, your physique initially will get its vitality from the glycogen saved in your muscle groups.

Within the case of a high-intensity working session, like interval coaching, the proportion of vitality produced by burning fats is considerably decrease.
