It is best to reduce the amount of lunch appropriately and eat eight points full. Personally, I think we should eat healthier food in the morning, such as bread, milk and eggs. Eating in the morning won't make you fat. Don't eat too much polysaccharide, fat and other foods, and don't eat too many snacks, especially puffed food. Don't eat too greasy things, it's easy to accumulate fat. I think it is easier to lose weight quickly by combining diet with exercise. It's better to do aerobic breathing instead of exercising, cycling, walking, jogging, climbing stairs and dancing. Don't use diet pills if you are too young, or you should mix diet and exercise reasonably.
