Try eating out less often, as the foods in restaurants often have high calories, cholesterol, and carbohydrates. When you do go to a restaurant, try to choose a healthy option, like a salad and a low-fat dressing or a sandwich without mayo.
Kids should have about 60 minutes of physical activity a day.
