What will happen to fat people's skin when they become thin people?
If you lose weight quickly, the skin will become slack without the support of fat, the surface will be unsmooth, and the pigment caused by slack may also be unevenly distributed. So I suggest you lose weight slowly, lose weight too fast, and your endocrine will be out of balance. If you are a woman, it will have a great influence on your later fertility and menstrual period, so it is recommended not to lose weight too fast.
