Resting metabolic rate

Resting metabolic rate (RMR) is the amount of energy your body needs to maintain essential functions like breathing, circulation, cell repair, and temperature regulation while at rest. It accounts for the largest portion of daily calorie expenditure and varies based on factors such as age, gender, body composition, and genetics. Essentially, RMR reflects how many calories your body burns when you're not actively moving or exercising, serving as a baseline for understanding your daily energy needs and supporting health and weight management goals.
