By examining the term 'Eating Disorders', it is generally used to describe eating patterns that out of the normal range. It usually implicates stern restriction of food intake, this is called anorexia nervosa (Grogan 1999). According to Myers (1998), "an eating disorder in which a normal-weight person (usually an adolescent female) diets and becomes significantly (15 percent or more) underweight, yet, still feeling fat, continues to starve."
