Does your body burn fat or muscle first when fasting?

You don’t need to burn muscle instead of fat, nor will your body automatically burn muscle while fasting. It’s possible to lose a bit of muscle mass when you fast, as you also lose water weight and visceral fat. However, it’s more likely you’ll maintain muscle mass rather than lose or gain it.
