Resting metabolic rate (RMR) was determined in 10 obese and 10 nonobese women after an overnight fast and for 3 h after the ingestion of an 800-kcal liquid meal. In the fasting state, absolute energy expenditure in the obese (4.8 +/- 0.2 kJ/min) was 25% greater than in the nonobese (P less than 0.005), but was comparable with the nonobese when expressed in relation to body surface area or lean body mass and was reduced by 20% when expressed per kilogram body weight3/4 (P less than 0.005). Meal ingestion resulted in a 14-16% increase in RMR (postprandial thermogenesis) that was similar in the two groups, so that absolute energy expenditure in the obese remained 22-25% higher than in the nonobese throughout the postprandial period. The estimated overall (fasting and postprandial) increase in resting caloric expenditure in the obese as compared with the nonobese was 350-375 kcal/day.
在10名肥胖女性和10名非肥胖女性中，于禁食过夜后以及摄入一顿800千卡流食餐3小时后测定静息代谢率（RMR）。在禁食状态下，肥胖者的绝对能量消耗（4.8±0.2千焦/分钟）比非肥胖者高25%（P<0.005），但以体表面积或瘦体重表示时与非肥胖者相当，以每千克体重3/4表示时则降低了20%（P<0.005）。进餐导致RMR增加14% - 16%（餐后产热），两组相似，因此在整个餐后期间，肥胖者的绝对能量消耗仍比非肥胖者高22% - 25%。与非肥胖者相比，肥胖者静息热量消耗的总体（禁食和餐后）估计增加量为350 - 375千卡/天。
