Resting Metabolic Rate (RMR) refers to the number of calories an individual’s body burns at rest to maintain basic physiological functions, such as breathing, circulation, and maintaining body temperature. Even when we are at rest, our body requires a certain amount of energy to sustain itself. RMR testing is a scientific method used to determine this basal metabolic rate accurately.
RMR testing typically involves analyzing factors such as oxygen consumption, carbon dioxide production, and minute ventilation, often through indirect calorimetry. During the test, a person breathes into a device that measures these gases, allowing for the calculation of their RMR.
