I have been exercising for four months. Why did I lose weight after stopping for a week? I gain muscle. After exercise, you will eat muscle gain powder and protein powder, and if you don't exercise, you won't eat it. If I stop for a week, I will gain weight. . My weight is 173,120kg, and my weight has not changed in the last two months. I seldom have more fat on my abdomen and thighs. People think I'm thin, but I do have a lot of fat. I eat protein powder and muscle powder. To put it bluntly, protein powder has less carbohydrates and muscle-building powder has more carbohydrates, but I feel that eating nothing has much effect. Exercise for more than an hour every day, and then run for half an hour, all of which are consumed by me.
