How can teenaged anorexia be reduced in the future?

Less teasing can give teens a better self-image and have them feel better about themselevs and their bodies. Some believe the media is at fault, and chanegs in advertsising / modeling can causes less people (particurly girls) to become anorexic. If teens stopped trying to be ecatly like a role model, that can also reduce future cases of anorexia.
