Basic Nutrition. All techniques to measure energy expenditure do so indirectly, and therefore the units generated have to be converted back into calories or kilojoules burnt or metabolised.

Rutenfranz and V Selinger, It is considered the reference, or criterion, method for measuring energy expenditure under controlled conditions (ie, in a laboratory). Direct calorimetry is the direct measure of energy expenditure measured by heat production using a human calorimeter. RMR constitutes 60 to 75% of daily energy expenditure and is the energy associated with the maintenance of major body functions. In clinical setting, assessment of energy expenditure allows to estimate nutrient requirements for patients during nutrition support [7]. 15 (FAO, Rome, 1957).
