It's almost never a good idea for a kid to try to gain weight, especially by eating lots of junk food. It may seem strange when many people want to be thinner that some kids want to gain weight. But kids who are thin sometimes feel like they aren't the right size. And they might even get teased about their size.
People come in different shapes and sizes. You might have friends the same age who weigh a lot more than you do. That doesn't mean that either of you is the wrong weight.
Being teased is one reason thin kids sometimes want to add pounds. It's never fun to be picked on. If this happens to you, be sure to tell a grown-up who can help. You might also rehearse what you will say back to someone who teases you. Don't insult anyone, but maybe say, "That's just the way I am. Everybody is different." Having friends who back you up can help you feel braver and less alone.
Small kids especially want to know how to help their bodies grow and develop. The best advice for them is the same as the health advice for all kids: Eat a healthy balance of foods, get plenty of activity (play time), and don't skimp on sleep.
Trying to gain weight by stuffing yourself with extra calories is a bad idea. It can make you feel sick and is not healthy — so just listen to your appetite and eat only as much as your body tells you to. If your size concerns you, talk with your mom or dad. They can help figure out whether you should see your doctor.
Once in a while, a health problem can keep a kid from gaining weight. The kid usually goes to a specialist who can check things out, or to a registered dietitian who has lots of tips on how to eat well. But most of the time, thin kids don't need to see a doctor or go on a special diet.
Here's another surprise. Kids who are thin need to exercise. A lot of people use exercise to keep their weight under control or to lose weight. But exercise serves many other purposes, too. Moving around helps you develop important skills and helps your body get stronger. And unless a kid has gone through puberty, weightlifting won't build bigger muscles. It also could hurt bones, joints, and muscles if it's not done correctly.
You want to help your body, not hurt it. Treat it right and you'll grow and develop just the way you should.
