Why did you gain three or four pounds when you came back from climbing the mountain?

In fact, the correct diet is the most effective way to lose weight, not to eat less, but to eat more and eat more things your body needs; In addition, your strenuous exercise is supposed to consume a lot of fat, but it may be because you sleep irregularly and the things your body supplements can't be absorbed normally, resulting in a surplus of things that are not absorbed in your body. . . So instead of losing weight, you gained weight.
