First, long-term dieting will reduce the metabolic rate of the body. Low metabolic rate means eating less than others but gaining more weight than others;

Reason 2: Dieting is not a long-term solution. As soon as you return to your diet, you will eat more easily because you are hungry for a long time than if you don't lose weight. Even if you eat normally or even less, you will gain weight as long as you are not on a diet.

reason 3: even if you can eat as little as dieting all your life, you will still be fat, because the metabolic rate of the human body will automatically decrease with age, and you can only maintain your figure by eating less and less, and the old will grow faster due to lack of nutrition.

Therefore, it is best to exercise. It is healthy from the inside out and can maintain your figure. The key is that there are lines that are not bamboo poles.
