How Can Excess Weight Hurt Your Health?

It's hard to feel good when your body has too much weight to carry. Being overweight or obese can make it harder to breathe and sleep. It can make a person feel tired and cause aches or pains. A weight problem also can make you embarrassed, sad, or even angry.

___________________________?

One of the best ways to stay at a healthy weight is to be active. You can join a sports team. Or, if you don't like team sports, try swimming, tennis, martial arts, or just being active in your own backyard. Jumping rope, dancing, and running around will get your heart pumping.

Getting some extra exercise can be as easy as taking the stairs instead of the elevator or walking instead of having your parents drive you. Being active also means watching less TV and playing fewer video games.

___________ is another part of staying fit. Aim to eat a variety of foods and get five servings of fruits and vegetables a day. Choose water and low-fat milk over soda and other sugary drinks. When it comes to high-calorie and high-fat foods, eat them only once in a while and, when you do, have smaller portions.

What Should You Do?

Talking to a parent is the best first step if you are concerned about your weight. Your mom or dad can make a doctor's appointment for you. The doctor may suggest ways of changing your eating and exercise habits.

In general, kids don't need to diet. But a kid who is very overweight may need some expert help from a dietitian or a doctor who specializes in weight management. Together, along with your family, you'll be able to come up with a safe and healthy plan that should include eating nutritious foods and exercising regularly.
