Anorexia nervosa at normal body weight!--The abnormal normal weight control syndrome.

Disgust with "fatness" and a consequent preoccupation with body weight, coupled with an inability to reduce it to or sustain it at the desired low level, characterizes the abnormal normal weight control syndrome. Individuals remain sexually active in a biological sense and often also socially. Indeed their sexual behaviour may be as impulse ridden as is their eating behaviour, which often comprises phases of massive bingeing coupled with vomiting and/or purgation. The syndrome is unlike frank anorexia nervosa in that the latter involves a regression to a position of phobic avoidance of normal body weight and consequent low body weight control with inhibition of both biological and social sexual activity. In abnormal normal weight control there is a strong and sometimes desperate hedonistic and extrovert element that will often not be denied so long as body weight does not get too low. Individuals nevertheless feel desperately "out of control" and insecure beneath their bravura. The syndrome is much more common in females than in males. There is a clinical overlap with anorexia nervosa and obesity in many cases as the disorder evolves. Depression, stealing, drug dependence (including alcohol) and acute self-poisoning and self-mutilation are common complications. Clinic cases probably only represent the tip of the iceberg of the much more widespread morbidity within the general population. Like anorexia nervosa and for the same reasons the disorder is probably more common than it used to be.
