A contributory cause is that young women try to be beautiful and slim by means of a course of slimming diets and these often cause eating disorders to begin. Their ideal of slimness doesn't correspond with the body's natural needs, and therefore young women try to suppress their nutritional needs in order to achieve slimness. Once they have begun to suppress their nutritional needs, an eating disorder arises which later becomes permanent, whether or not they have achieved their ideal.
