Energy intake, body weight and resting metabolic rate (RMR) were measured on seven days consecutively, in 20 men and 14 women on ad libitum food intake under free-living conditions. These measurements were repeated in 8 men and 9 women twice with an interval of two months. Mean energy intake (EI) as measured by 'Weightment' method, was 2820 +/- 577 kcal/d in men and 1611 +/- 147 kcal/d in women. EI showed significant differences between weeks (P less than 0.01, CV = 13.1% in men and 9.5% in women) and between subjects (P less than 0.05, CV = 13.7% in men and 9.8% in women). Intra individual variance contributed up to 60 to 70 per cent of the total variance in EI in both the groups. RMR measured by using Oxylog, varied between the three periods (CV = 6% in men and 5.9% in women) and between subjects (CV = 5.7% in men and 12.3% in women). Mean RMR of both men and women was lower than the predicted value by FAO/WHO/UNU equation. Estimate of mean 24 h energy expenditure, using activity diary and factorial method, in the first round was 2458 +/- 144 kcal in men and 1655 +/- 172 in women, resulting in an energy balance of 308 kcal in men and -44 kcal/d in women. The pattern of activity remained the same in the three rounds for both groups. There were no significant changes in weight (CV-1.6%) or per cent body fat during the study period (P greater than 0.1).
在自由生活条件下，对20名男性和14名女性连续7天随意进食时的能量摄入、体重和静息代谢率（RMR）进行了测量。8名男性和9名女性在两个月的间隔后重复进行了两次这些测量。通过“体重测量”法测得的男性平均能量摄入（EI）为2820±577千卡/天，女性为1611±147千卡/天。EI在各周之间存在显著差异（男性P＜0.01，CV = 13.1%；女性P＜0.01，CV = 9.5%），在个体之间也存在显著差异（男性P＜0.05，CV = 13.7%；女性P＜0.05，CV = 9.8%）。两组中个体内部差异在EI总差异中所占比例高达60%至70%。使用氧耗仪测得的RMR在三个时期之间有所不同（男性CV = 6%，女性CV = 5.9%），在个体之间也有所不同（男性CV = 5.7%，女性CV = 12.3%）。男性和女性的平均RMR均低于粮农组织/世界卫生组织/联合国大学方程的预测值。在第一轮中，使用活动日记和因子法估计的男性平均24小时能量消耗为2458±144千卡，女性为1655±172千卡，男性的能量平衡为308千卡/天，女性为 -44千卡/天。两组在三轮测量中的活动模式保持不变。在研究期间，体重（CV = 1.6%）或体脂百分比没有显著变化（P＞0.1）。
