It is true that skipping meals at night can achieve the effect of losing weight quickly in a short time, but the method of losing weight without eating at night is not scientific. Because dieting in this way can reduce the body's calorie intake, it can achieve a temporary weight loss effect, but in the long run, it will cause harm to the stomach and easily rebound, and once it rebounds, it will make people fatter and more difficult to lose weight. Dinner can be light, eat less greasy and sweets, eat three or four hours before going to bed, eat five or six minutes full, and exercise moderately after half an hour.
