Which technique is considered to be the “gold standard” for estimating total energy expenditure (TEE)?

Question

Quizplus · Accepted Answer

The use of doubly labeled water is considered the "gold standard" for estimating TEE as it is a highly accurate and precise method that measures total energy expenditure over an extended period of time. This method involves the ingestion of a known amount of water that is labeled with stable isotopes of hydrogen and oxygen, and subsequent measurement of the rate of disappearance of these isotopes from the body through urine and breath samples. The rate of disappearance is proportional to the metabolic rate and thus provides an estimate of TEE.
