Eat less and exercise more. Exercise more than 1 hour every day, such as hula hoop and skipping rope. Don't walk. The effect of walking is not obvious, no snacks and no drinks. Drinks are too sweet, so you can drink tea and water. Control the food intake of each meal, and be sure to eat breakfast, or you will get stomach trouble. Don't sit still after eating, stand for at least 15 minutes. This is the process of my losing weight. I lost weight 10 kg this summer vacation.
