A classmate in our class, she used to be very fat and had a big face. In the process of losing weight, we obviously felt that her skin was flabby, because there was a lot of meat on her face, but now all that meat is gone, so flabby is inevitable. The face tends to turn black after relaxation, and the whole person looks very poor, so I think losing weight will really lead to poor skin. 2. The skin deterioration caused by weight loss can actually be adjusted.
The human body has the function of self-repair, and the skin has super elasticity. Although my classmate's face was slack at first, she took active exercise and paid attention to her diet, and her skin slowly came back. Although you can still see a little slack, you can't see it without looking carefully, and it basically doesn't affect your appearance. So we can all recuperate. In theory, you can lose weight only through exercise without dieting, but in practice it is very difficult.
Exercise consumes human calories, and dieting controls the calories absorbed by the human body. When we consume more calories than the human body absorbs, our body will slowly lose weight, thus achieving the goal of losing weight. If we don't go on a diet, we will absorb a lot of calories. We need a lot of exercise to burn these calories. We need to run for half an hour to consume these calories, so the amount of exercise required is huge, and few people can really do it.
In short, losing weight does lead to skin deterioration, but it can also be recovered through conditioning. Both exercise and diet can lose weight. In theory, you can lose weight just by exercising, but in practice it is very difficult. To lose weight, you should exercise and control your diet.
