Don't deliberately go on a diet because you can't stick to it. How can you eat only one apple for dinner all your life? In addition, excessive dieting can lead to malnutrition. Eat normally, have a little moderation, get rid of bad eating habits, such as eating less sugar and fatty foods, and having a full dinner at 7: 00, not too much. Do aerobic exercise, brisk walking, jogging and so on, and stick to it. Exercise brings happiness and health.
