Self-selected food intake of 15 reduced-obese women living in a metabolic ward was studied for 14 consecutive days to determine the effect of exercise and other metabolic and behavioral variables on energy intake. A choice of prepared food items were offered at breakfast, lunch and dinner, and a variety of additional food items were available continuously 24 h/day. Subjects performed either moderate intensity aerobic exercise (A-EX) (n = 8) expending 354 +/- 76 kcal/session or low intensity resistance weight training (R-EX)(n =7) expending 96 +/- kcal/session, 5 days/week. Mean energy intakes (kcal/day, +/- SEM) of the exercise groups were similar: 1867 +/- 275 for A-EX, 1889 +/- 294 for R-EX. Mean energy intakes of individuals ranged from 49 to 157% of the predetermined level required for weight maintenance. Resting metabolic rate per kg 0.75 and the Eating Inventory hunger score contributed significantly to the between subject variance in energy intake, whereas exercise energy expenditure did not. Regardless of exercise, eight women consistently restricted their energy intake (undereaters), and seven other consumed excess energy (overeaters). Overeaters were distinguished by higher Eating Inventory disinhibition (P = 0.023) and hunger (p = 0.004) scores. The overeaters' diet had a higher fat content 34 +/- 1% (p = 0.007). Also, overeaters took a larger percentage of their daily energy, than that of undereaters, 27 +/- 1 energy intake in the evening, 13 +/- 2%, compared to undereaters, 7 +/- 1% (p = 0.005). We conclude that the Eating Inventory is useful for identifying reduced-obese women at risk of overeating, and these individuals may benefit from dietary counseling aimed at reducing fat intake and evening snacking.
对居住在代谢病房的15名体重减轻的肥胖女性的自选食物摄入量进行了连续14天的研究，以确定运动以及其他代谢和行为变量对能量摄入的影响。早餐、午餐和晚餐提供多种预制食品，并且每天24小时持续供应各种其他食品。受试者进行中度强度有氧运动（A-EX）（n = 8），每次消耗354±76千卡，或低强度抗阻重量训练（R-EX）（n = 7），每次消耗96±千卡，每周5天。运动组的平均能量摄入量（千卡/天，±标准误）相似：A-EX组为1867±275，R-EX组为1889±294。个体的平均能量摄入量为维持体重所需预定水平的49%至157%。每千克0.75的静息代谢率和饮食量表饥饿评分对受试者之间能量摄入的差异有显著贡献，而运动能量消耗则没有。无论运动情况如何，8名女性持续限制能量摄入（进食不足者），另外7名女性摄入过多能量（进食过量者）。进食过量者的饮食抑制量表得分（P = 0.023）和饥饿评分（p = 0.004）更高。进食过量者的饮食脂肪含量更高，为34±1%（p = 0.007）。此外，与进食不足者相比，进食过量者在晚上摄入的能量占每日能量的百分比更大，为27±1%，而进食不足者为7±1%（p = 0.005）。我们得出结论，饮食量表有助于识别有暴饮暴食风险的体重减轻的肥胖女性，这些个体可能会从旨在减少脂肪摄入和夜间吃零食的饮食咨询中受益。
