Body composition and resting energy expenditure in women with anorexia nervosa: Is hyperactivity a protecting factor?

Background: In subjects with anorexia nervosa (AN) physical exercise may cause or even prevent weight loss, body composition alterations and adaptive thermogenesis. To investigate the influence of behavioral patterns on body composition and energy expenditure in women with AN, we conducted a retrospective analysis in 62 patients with AN referring to our outpatients' clinic.
