The double-labeled water method was used to measure average daily total energy expenditure (EE) in 11 healthy normal-weight women classified as unrestrained eaters, in 8 patients with anorexia nervosa, and in 8 patients with bulimia nervosa. The body mass index was 20.0 +/- 1.3 kg/m2 in the control group, 15.2 +/- 5.6 kg/m2 in the anorectic groups, and 19.7 +/- 1.9 kg/m2 in the bulimic group. EE was measured over a 2-week period during which weight remained constant in all groups and was 2357 +/- 504 kcal/day for the controls, 2510 +/- 920 kcal/day for the bulimics, and 2899 +/- 656 kcal/day for the anorectics. Differences were not significant among groups. Physical activity was recorded in diaries by all subjects. Anorectic patients showed significantly more activity than all other groups. The data suggest that EE is high in anorectic patients as a consequence of physical activity.
采用双标记水法测量了11名被归类为无节制饮食者的健康正常体重女性、8名神经性厌食症患者和8名神经性贪食症患者的平均每日总能量消耗（EE）。对照组的体重指数为20.0±1.3kg/m²，厌食组为15.2±5.6kg/m²，贪食组为19.7±1.9kg/m²。在为期2周的时间内测量了能量消耗，在此期间所有组的体重均保持恒定，对照组为2357±504千卡/天，贪食症患者为2510±920千卡/天，厌食症患者为2899±656千卡/天。各组之间差异不显著。所有受试者都通过日记记录了身体活动情况。厌食症患者的活动量明显高于所有其他组。数据表明，由于身体活动，厌食症患者的能量消耗较高。
