Prevention is any systematic attempt to change the circumstances that promote, initiate, sustain, or intensify problems like eating disorders. This may involve reducing negative risk factors (such as body dissatisfaction, depression or basing self-esteem on appearance) or increasing protective factors (such as a non-appearance oriented self-definition, and replacing dieting and body snarking with intuitive eating and appreciation for the body’s functionality). Prevention is important to reduce the suffering associated with eating disorders. Treatment is often expensive and difficult to obtain, which makes prevention even more important.
