It is no fun for you to worry all the time about how much you weigh, how much you eat, or whether you are thin. Eat when you are hungry. Stop eating when you are full.
All foods can be part of healthy eating.
If you are sad or mad or have nothing to do and you are not really hungry find something to do other than eating. Often, talking with a friend or parent or teacher is helpful. Kids and adults who exercise and stay active are healthier and better able to do what they want to do, no matter what they weigh or how they look. Good health, feeling good about yourself, and having fun go hand in hand. Try out different hobbies, like drawing, reading, playing music, or making things.
