To lose weight quickly in a short time, diet control is more effective than exercise. But don't simply eat fruit or drink milk, because it seems to take effect quickly, but in fact, excess water in the body is discharged due to insufficient salt intake. As long as enough salt is added, the weight will rebound. Just reduce the amount on the basis of normal diet, don't be partial to food, or even eat too lightly, because fatty foods are high in calories, but the process of digestion and absorption is slow; And foods with low calories tend to metabolize quickly. Try to eat less and drink more water without discomfort. Taking exercise as an auxiliary means is mainly to ensure good health. If you don't have the habit of exercising before, you must exercise when you are excited or not hungry. If you don't have physical strength, don't force it. The process of losing weight should not last forever. It is not good to rush for success, and it is more harmful to people to be in a state of insufficient calories for a long time. You should spend a few days to arrange a day or two off. I don't know why you are so eager to lose weight, as long as you don't overdo it, stay healthy and let nature take its course. Internal sources say that the national rhythmic gymnastics team is almost 100% malnourished and anaemic, which is the result of long-term weight control. Losing weight must be based on ensuring health.
