The term "resting metabolic rate" (RMR) refers to the amount of energy expended by the body at rest to maintain basic physiological functions such as breathing, circulation, and thermoregulation. RMR is influenced by various factors, including age, gender, body composition, and genetic predisposition. Understanding RMR is essential for determining an individual’s caloric needs and can aid in effective weight management or loss strategies. A higher RMR indicates a higher caloric burn at rest, contributing to overall energy expenditure.
