Anorexia nervosa (AN) condition presents a serious and potentially life-threatening eating disorder characterized by episodes of self-starvation and excessive weight loss that may be accompanied by excessive exercise. The notion that the condition offers a dysfunctional system of individuals’ self-evaluation of self-worth, where self-worth as determined from perceived body shape and weight and the degree to which they consider themselves to be in control of their own shape and weight. The control need and necessity for specific body shape and weight appears to drive the pathologic dietary restraint and the consequent operationalization of these tendencies into various behavioural expressions and dietary rules that may either lead to success, e.g. outcome weight loss, or fail in implementation, e.g. resulting in subjective or objective binge eating episodes for example, often induced by the failure of restriction to dietary rules.
