(TDEE) (tō'tăl dā'lē en'ĕr-jē ek-spen'di-chŭr)
Total daily caloric expenditure, consisting of basal metabolic rate, diet-induced thermogenesis, and energy expenditure for physical activity; in the clinical setting, TDEE can be estimated by calculation or measured by indirect calorimetry.

2006) A simple method of measuring total daily energy expenditure and physical activity level from the heart rate in adult men.
Such activity thus has little influence on total daily energy expenditures (Westerterp and Plasqui, 2004).
Because the cost of body movement is increased, overweight individuals may match the total daily energy expenditures of their leaner peers once obesity has developed.
However, in view of the fact that BMR makes a variable contribution to total daily energy expenditure, from 45% down to [approximately]27% (Kleiber 1961, Nagy 1987), and that, at least for one mammal, the marmot (Marmota flaviventris), a relatively low BMR does not translate into a reduced FMR (Salsbury and Armitage 1994), the coupling between BMR and metabolism in the field remains unclean As a result, the evolutionary and ecological significance of a diminution in BMR is still an unresolved problem, despite attempts to place variation in basal metabolism into an ecological framework (McNab 1980, 1984, 1986, Bennett 1988).
Evaluation of metabolism under laboratory conditions in combination with estimates of FMR as given [TABULAR DATA FOR TABLE 3 OMITTED] by DLW provide a useful tool for dissecting total daily energy expenditure into components (McNab 1989).
1996) calculated that locomotion accounted for 21% of total daily energy expenditure for the swift fox (Vulpes velox), the highest proportion so far reported for a mammal.
There is substantial evidence to suggest that changes to daily living have resulted in a chronic depletion in total daily energy expenditure, specifically physical activity thermogenesis (Cavadini et al.
Total daily energy expenditure, activity thermogenesis and the prevention of excessive weight gain
Total daily energy expenditure was assessed using doubly-labelled water in 2 to 7 year olds, and activity thermongenesis and physical activity level calculated.
