ELI5: Muscle repair process: what happens specifically when post workout calories are consumed, and during sleep?
gpt
Nothing happens when post workout calories are consumed.  That is bro-science.  You will be fine if you don't drink your protein shake exactly 10-30 minutes after working out unless you were already suffering an extreme calorie deficiency over the preceding days and your body fat percentage is already very low.  Your body will only catabolize muscle tissue in extreme situations, and even the most extreme workouts don't consume as many calories as you think.

As far as sleeping: muscle growth is regulated by free testosterone, which is released in a pulsative fashion.  The biggest pulse occurs at night when you are asleep.  It signals your damaged muscle tissue to heal, and then the cells/fibers to lengthen and thicken so that you will have an increased mechanical advantage the next time you attempt a similar physical feat.
