What does resting metabolic rate (RMR) refer to?

Resting metabolic rate (RMR) refers to the number of calories your body uses while at rest to maintain essential physiological functions, such as breathing, circulation, and cellular production. This measurement is important because it gives insight into the baseline caloric needs of the body when not engaged in any physical activity.

Understanding RMR can help in designing effective dietary and exercise plans since it represents the energy expenditure required to sustain life in a resting state. It is distinct from calories burned during exercise, digestion, or daily activities, which occur above and beyond what the body requires for basic functioning. RMR is a crucial component in calculating an individual's total daily energy expenditure, allowing for better management of weight and overall fitness goals.
