Quizplus · Accepted Answer

Indirect calorimetry measures energy expenditure by analyzing oxygen consumption and carbon dioxide production. This method can be used under both resting and physically active conditions and is the most commonly used method. Direct calorimetry measures heat production, while doubly labeled water and DXA are not used to measure energy expenditure.
