The scientific way to lose weight is to control calorie intake and increase activity, and achieving a balanced diet to lose weight is a systematic project, which takes a long time. Often ordinary diet can also cause malnutrition to varying degrees. Under normal circumstances, food intake will increase after exercise. If you can't persevere, once the amount of exercise drops sharply, your appetite will not drop, but will become fat. If you repeatedly increase or decrease the amount of exercise for a period of time, your weight will fluctuate, and it may become heavier and heavier, or it may increase-decrease-increase, which is even worse for your health.
