It is important to realise that stringent dieting plays a key role in problems of this nature but eating disorders are not simply cases of dieting that has become out of control.
Eating disorders are not just about trying to live up to media images of attractiveness, though social pressure to be thin may be a key factor.
Eating disorders can easily arise out of a response to distress and worries about areas of life other than body image or dieting.
Food is only part of the story.
