For family members of children and teens

There are many ways adults can help children and teens form a healthy view of themselves and learn to approach food and exercise with a positive attitude. Doing this may prevent some children and teens from developing this disorder. See tips for developing:

• A healthy view of self and others. Teach children to take good care of their bodies. Avoid making comments that link being thin to being popular or healthy.
• A healthy approach to food and exercise. Avoid punishing or rewarding your children with food. Be a good role model for healthy eating and exercising.
