Dieting is not recommended because it is tantamount to suicide.
If your budget (money) is available, you can go to a beauty hospital for liposuction, which is quick. Of course, if you don't pay attention to it later, it will rebound. Or you are too lazy, you can also ask a professional dietitian to help you lose weight through a professional diet; If you are going to spend no money, and you are diligent and persistent enough, exercise.
In fact, a person's fatness is also related to heredity, and it is also closely related to personal living habits and eating habits.
In short, there is no weight loss once and for all. Because you need to survive, and survival needs to eat, and people's physiology will change with age and endocrine disorders.
