Instead, eat a healthy, balanced diet. Exercising and playing are really important, too, because physical activity burns calories. Your body needs calories just to operate — to keep your heart beating and your lungs breathing. As a kid, your body also needs calories and nutrients from a variety of foods to grow and develop.
