Most measurement approaches in use today involve the measurement of oxygen consumption and/or production of carbon dioxide via indirect calorimetry. measurement of the heat ouput of the body is thus also a measure They should always be checked to make sure that with the bicycle test. What are the differences between a male and a hermaphrodite C. elegans? The two indirect methods for measurement of energy expenditure in individuals commonly used are: This is a closed-circuit breathing apparatus which is filled with oxygen and has a capacity of about 6 litres. For example, weight loss can increase hunger and decrease energy expenditure which may trigger a recurrence of weight gain. Current practices are reviewed for measuring energy expenditure by indirect calorimetry (respiration chambers, ventilated hoods, doubly labeled water) and direct calorimetry (rooms, suits). .

Where high accuracy is required and sufficient resources are available, an open-circuit indirect calorimeter can be used. TEE can be subdivided into basal energy expenditure (BEE, or basal metabolic rate; BMR), diet-induced thermogenesis (DIT, or thermic effect of feeding; TEF), and physical activity-related energy expenditure (AEE).
