Abnormal nutritional status and dietary patterns are central features
of the eating disorders. Normalization of these features are key compo
nents of treatment and recovery because they are powerful perpetuating
factors. Restrictive diets, fat avoidance, and abnormal cognitive and
perceptual patterns are typically present, in addition to altered nut
ritional parameters because of hormonal and metabolic factors. The pri
mary goal of nutrition intervention in the patient with anorexia nervo
sa is to promote weight gain through increased energy intake, expansio
n of the diet, and knowledgeable and empathetic dietary counseling. A
regular pattern of nutritionally balanced, planned meals and snacks, a
nd the avoidance of restrictive dieting, are essential elements of tre
atment for the patient with bulimia nervosa. As a member of the multid
isciplinary treatment team, the dietitian or nutrition professional wi
th knowledge of nutritional science, counseling skills, and a nonjudgm
ental attitude can provide expertise in this area.
