Caloric requirements for weight gain in subgroups of anorectic patients (anorectic restrictors, anorectic binge-purgers) and weight maintenance in subgroups of anorectic and bulimic patients (bulimics with and without a prior history of anorexia nervosa) were studied in a total of 36 patients. No significant differences were found between subgroups of anorectic patients either in calories to gain weight or to maintain a normal weight. Bulimic patients, as a group, were found to require significantly fewer [corrected] calories than the group of anorectic patients to maintain a normal weight. Bulimic patients with a prior history of anorexia nervosa were found to require more calories for weight maintenance than bulimics with no such prior history. In the entire eating disorder population, there was a significant negative correlation between highest premorbid body mass index (BMI) and calories required to maintain weight. These findings suggest that differences in energy metabolism may be present in the eating disorder subgroups.
对总共36例患者进行了研究，以确定厌食症患者亚组（限制型厌食症患者、暴食-清除型厌食症患者）体重增加的热量需求以及厌食症和贪食症患者亚组（有和没有神经性厌食症病史的贪食症患者）维持体重的热量需求。在厌食症患者亚组中，无论是增加体重还是维持正常体重所需的热量方面，均未发现显著差异。作为一个整体，贪食症患者维持正常体重所需的热量明显少于厌食症患者组。有神经性厌食症病史的贪食症患者维持体重所需的热量比没有这种病史的贪食症患者更多。在整个饮食失调人群中，病前最高体重指数（BMI）与维持体重所需的热量之间存在显著的负相关。这些发现表明，饮食失调亚组中可能存在能量代谢差异。
