The relationship between energy consumption and body composition was evaluated in 63 women by use of energy-intake values that were precisely measured in a metabolic unit and corrected for deviations from energy balance. Energy requirement for the maintenance of body weight was not significantly correlated with adiposity expressed as percent body fat. However, energy requirement was positively associated with lean mass (p less than 0.0001) whereas fat mass added no predictive value to the same multivariate regression equation. Self-reported energy intake (before the experiments) was not correlated with lean mass and was underestimated by lean subjects at least as much as by obese subjects. Discrepant findings in the literature concerning relationships between obesity and energy intake may be explained by reporting error and by the relative lean mass of obese vs nonobese women but not by systematic underreporting unique to obese subjects.
通过使用在代谢单元中精确测量并针对能量平衡偏差进行校正的能量摄入值，对63名女性的能量消耗与身体组成之间的关系进行了评估。维持体重所需的能量与以体脂百分比表示的肥胖程度无显著相关性。然而，能量需求与去脂体重呈正相关（p<0.0001），而脂肪量对同一多元回归方程没有预测价值。自我报告的（实验前）能量摄入量与去脂体重无关，瘦受试者至少与肥胖受试者一样低估了能量摄入量。文献中关于肥胖与能量摄入之间关系的不一致发现，可能是由于报告误差以及肥胖女性与非肥胖女性的相对去脂体重所致，而非肥胖受试者特有的系统性低报。
