What Happens to Your Muscles When You Exercise Before Breakfast
Is it safe to exercise before breakfast, or does your body really start burning muscle? In this video, we go inside your muscle cells to see what actually happens when you work out on an empty stomach. You’ll learn how your body switches fuel, what ATP, glycogen, AMPK and mTOR really do, and why the “fasted cardio” debate is more complicated than most people tell you.
We also look at what the research says about fat burning, muscle protein breakdown, cortisol, and workout performance, plus who should be careful and what to do if you want to train in the morning.
