When some people make up their minds to lose 10 Jin soon, they often choose a way called "collapse therapy". In this way, you can't eat any other food except a little grapefruit or cabbage soup every day. In this way, your daily calorie intake will be less than 1000 calories. Maybe in the first few days, you will feel that you have really lost a lot of weight. But in a few days, you will find that your weight has not changed much. This is because you consume too few calories, so your metabolism can't be effectively driven, and your metabolism slows down and you can't effectively consume your calories. This is a kind of self-balance of human body. Also, once you break this balance again, when your diet increases slightly, your consumption will not increase, but your absorption will increase, so you will gain weight.
