Key facts

Method used to measure RMR
Resting metabolic rate (RMR), sometimes called resting energy expenditure (EE), can be measured by direct calorimetry using a metabolic chamber. In the chamber, the difference in the temperature of water entering and leaving the chamber reflects the patient's heat production. Direct calorimetry is conducted in controlled environmental chambers, but the clinical and practical application using this technique is quite limited.[PMCIDPMC3928639]
