Abstract Objective: To compare self‐reported and measured energy intake in weight‐restored patients with anorexia nervosa (AN), weight‐stable obese individuals (OB), and normal weight controls (NC).Method: Forty participants (18 AN, 10 OB, and 12 NC) in a laboratory meal study simultaneously completed a prospective food record.Results: AN patients significantly ( p = .018) over‐reported energy intake (16%, 50 kcal) and Bland‐Altman (B‐A) analysis indicated bias toward over‐reporting at increasing levels of intake. OB participants significantly ( p = .016) under‐reported intake (19%, 160 kcal) and B‐A analysis indicated bias toward under‐reporting at increasing levels of intake. In NC participants, NS ( p = .752) difference between reported and measured intake was found and B‐A analysis indicated good agreement between methods at all intake levels.Discussion: Self‐reported intake should be cautiously interpreted in AN and OB. Future studies are warranted to determine if over‐reporting is related to poor outcome and relapse in AN, or under‐reporting interferes with weight loss efforts in OB. © 2012 by Wiley Periodicals, Inc.
