Personally, if you exercise for too long and can't supplement good nutrition, especially in protein, natural muscles will reduce more than fat;

1. When exercising, the energy supply order of our human body is sugar, fat and protein; If you exercise for a long time, the human body will consume protein as an energy substance;

2. After exercise, many muscle fibers in the human body are damaged, and these damaged muscle fibers will repair themselves, so protein is naturally needed. This is because if we don't supply it with protein, the muscles won't grow well.

3. In the usual diet, eat more high-protein foods, such as hydrolyzed whey protein, and eat less fat.
