In 14 overweight women, 24-h energy expenditure (EE) was measured in a whole-body indirect calorimeter: before weight reduction (100% diet), after 1 wk on a 4.2-MJ diet, after 8 wk on 4.2-MJ diet, after weight reduction on 100% diet. Data of two subjects were excluded. Mean body weight declined from 93.3 +/- 7.4 (mean +/- SD) to 83.4 +/- 7.7 kg; 24-hEE decreased from 10.52 +/- 0.83 MJ on the 100% diet to 9.58 +/- 0.75 MJ on the 4.2-MJ diet. After 8 wk, 24-hEE had decreased by 15% of the initial 24-hEE to 8.92 +/- 0.65 MJ. After refeeding (1 wk), it increased to 9.45 +/- 0.75 MJ. Calculated energy requirement before weight reduction was 10.62 +/- 0.88 MJ/day; after weight reduction, 9.39 +/- 0.79 MJ/day. The decrease was more than that predicted from the change in body weight and body composition. An adaptation probably occurs, which may be metabolic.
对14名超重女性，使用全身间接热量计测量其24小时能量消耗（EE）：在体重减轻前（100%饮食）、4.2兆焦饮食1周后、4.2兆焦饮食8周后、100%饮食体重减轻后。排除了两名受试者的数据。平均体重从93.3±7.4（平均值±标准差）千克降至83.4±7.7千克；24小时EE从100%饮食时的10.52±0.83兆焦降至4.2兆焦饮食时的9.58±0.75兆焦。8周后，24小时EE下降至8.92±0.65兆焦，较初始24小时EE减少了15%。重新进食（1周）后，其增加至9.45±0.75兆焦。体重减轻前计算的能量需求为10.62±0.88兆焦/天；体重减轻后为9.39±0.79兆焦/天。这种减少超过了根据体重和身体成分变化所预测的数值。可能发生了一种适应性变化，这可能是代谢性的。
