The issue of eating disorders is far to complicated for what must be a short post. But, there is much more to ED's than just anorexia and Bulimia. Frankly I think even the absolute obsession with a certain dietary plan can be a form of ED. No obsession is healthy. Like anorexia and bulimia compulsive fasting can be a form of extreme control. No human body will happily or safely fast for over 100 days, the compulsive mind takes over control and the natural protection instincts of the body are lost. That is why I say use fasting as a tool, not a means to an end. More later perhaps....
