First, don't start from hunger (I heard that some people eat roundworms effectively, but few people dare to eat them). If you don't eat for five days, your internal organs may fail, and it's useless to save them. If you don't like it, eat seven points full.
Second, partial weight loss is impossible. Local muscle exercise does not consume fat near the muscles. Fat can only be consumed as a whole, with an average reduction.
Don't confuse losing weight with shaping. It takes a lot of repetitive actions, and short-term exercise can only build long muscles. As a result, you want to lose more muscles instead of reducing them.
Third, don't use plastic wrap or anything like that, it's used by competitors before the game. The effect is super obvious, but it only reduces water, not fat! Drinking water immediately puts on weight. My coach gained 2 kilograms before the game, so he just ran 5 kilometers in a raincoat. It was still summer and I was sweating like a pig. )
Exercise continuously for more than 40 minutes (jogging, badminton, table tennis, aerobics, etc.). Can be changed at any time according to personal preference) twice a day. The amount of exercise can be as small as walking fast, but it can't stop. Slowly shrink your whole body. 1 year to see the effect. If you want to lose weight quickly, you should extend your exercise time. All you need is persistence.
Exercise within 40 minutes is only consuming what you eat today, and the circulatory system that consumes body fat has not yet started.
