Resting Metabolic Rate (RMR) Calculator
Calculate your Resting Metabolic Rate — the calories your body burns at complete rest.
Your RMR
0 cal/day
RMR is the calories your body burns just to stay alive — breathing, circulation, cell repair. It accounts for 60–75% of total daily calorie burn. Muscle increases RMR; fat decreases it relative to weight. Crash dieting reduces RMR significantly.
