Prevention

Parents can help prevent kids from developing an eating disorder by

nurturing their self-esteem, and encouraging healthy attitudes towards life, peer pressure, nutrition and appearance [9]

If parents develop their own healthy attitudes about food and exercise they can set an excellent example for their kids [7]
