On the premise of ensuring children's nutrition, change the food they eat into something helpful to lose weight, such as celery, spinach, tomatoes, peanuts and so on. And let children eat some fruits that are beneficial to weight loss, such as grapefruit and kiwi, which can not only ensure nutrition, but also help to lose weight. Then play sports with the children and run together. It will be of great help to children if they can get into the habit of running in the morning. It is good to reduce the number of drinks children drink and encourage them to drink refined tea and Pu 'er tea. Tea can not only effectively eliminate grease, but also be a traditional culture in China. It is good to encourage more and set more examples.
