How to Calculate Your RMR

RMR stands for resting metabolic rate, which is also known as your basal metabolic rate (BMR). Your RMR equals the number of calories that you would burn each day if you performed no physical activity. The formula for calculating your RMR varies depending on your gender. You can use your RMR to estimate your caloric intake needs because each person burns calories at a different rate. To calculate your RMR, you need to know your weight, height and age.
