Watch your diet. You can't eat too much and you can't help eating. You should be thin and healthy. It is not advisable to lose weight simply by dieting. Hungry and thin people are all water, and girls can lead to endocrine disorders. As long as you follow the principle of 7% fullness and eat less staple foods such as rice, steamed bread and noodles, you can use potatoes, sweet potatoes, pumpkins and corn instead of complementary foods. Eat less pork and moderate intake of chicken, fish and beef and mutton, especially fried chicken legs, chicken wings and barbecue. Secondly, exercise should be carried out with diet. For example, it is best to stand for a while after eating, and don't sit down immediately to let fat accumulate in your abdomen. The best exercise is swimming. If you can't afford it, you can run or practice yoga at home.
