  • Data are expressed as mean (95% CI).

  • BMR, basal metabolic rate; EIBDHQ, energy intake estimated by brief-type self-administered diet history questionnaire; EIDLW, energy intake calculated by the doubly labelled water and weight change during the doubly labelled water period; PAL, physical activity level; TEE, total energy expenditure.
