1 1 year-old children can take the following measures to lose weight: first, adjust their diet, that is, let children eat as little as possible high-calorie sweets and high-fat fried foods, which are very high in calories and fat. Eat as little as possible to let children lose weight quickly. Second, carbohydrates, that is, starchy foods, should also be eaten less, and more fresh fruits and vegetables should be eaten to supplement children's essential vitamins. Third, eat foods containing high-quality protein in moderation, such as milk, eggs, pork, beef and other lean meat, because children are still in the growth and development period. Fourth, little girls can't simply lose weight, let alone give their children diet pills. They must lose weight through diet and more exercise.
