TDEE is not just a single measure, but is calculated as a sum of the following three forms of energy: BMR, or basal metabolic rate. The CO 2 production, calculated from the subsequent difference in elimination between the two isotopes, is a measure of energy expenditure (Fig. be measured (sometimes in conjunction with oxygen uptake) during Energy is measured in calories, and your total daily energy expenditure (TDEE) is the number of calories you burn each day.
