Fortunately, there are a number of ways to boost your total daily energy expenditure (TDEE) and not all of them require a formal workout. The use of the stable isotope technique, doubly labelled water, enables total daily energy expenditure to be measured accurately in free-living subjects. More often, it is estimated using factors such as a persons basal metabolic rate (BMR), activity level, and the thermic effect of food. top 20 per cent and the bottom 20 per cent of a typical sedentary J Am Coll Nutr. normal daily life of the person and that is not too complicated We routinely measure resting energy expenditure (REE), dietary-induced thermogenesis, and activity energy expenditure.
