curious if when the body decides to take muscle as opposed to fat as engery, is muscle that is in the process of regrowth more prone to be used as enery other than established muscle. For example, if i had a great chest workout the night before, and then work up to do fasted cardio to the point that more than fat was being burned, would it be the chest muscles that are trying to grow be the first to be used as energy for the body?
