All components are calculated from TDEE measured by doubly labeled water except for sleep energy expenditure, which was calculated in a whole-room respiratory chamber. SEE = sleep energy expenditure, TEF = thermic effect of food, arousal = SEE – resting energy expenditure in the chamber, SPA = spontaneous physical activity (measured in whole-room chamber), PA = physical activity (calculated as TDEE minus all other components). Changes are presented with the baseline value adjusted as the covariate in the model. *=p<0.05
