resting metabolic rate (RMR)

Resting metabolic rate (RMR) is the amount of energy your body uses when you are at rest, just to keep essential functions like breathing, blood circulation, temperature regulation, and cell maintenance working. It accounts for the majority of your daily calorie burn. RMR varies based on factors like age, sex, body composition, and genetics. Understanding RMR helps in estimating daily energy needs and managing weight, as it provides a baseline of how many calories your body requires to function without any activity.
