Energy expenditure was measured over 10 d using the doubly-labelled water (DLW) and activity diary methods in summer and winter in subjects with « light » occupations but leisure activities which ranged from « non-active » to « very active ».
The basal metabolic rate (BMR) and the energy cost of activities were determined by indirect calorimetry.
The Department of Health (1991) predicted BMR for the group (6.89 (SD 0.30) MJ/d ; n 18) was not significantly different from the measured value (7.17 (SD 0.70) MJ/d ; n 18).
The range of DLW-derived expenditure values within the group was BMRx1.41 to 2.41.
The largest seasonal change within individuals was BMRx0.5.
