BMR Calculator

HOW DOES BMR WORK?

BMR (Basal Metabolic Rate) is an estimate of how many calories your body burns at rest. It represents the minimum amount of energy needed to keep your body functioning, including breathing and keeping your heart beating. Your BMR uses up about two-thirds of your daily calories. Your caloric intake to lose, maintain, or gain weight will be based on your BMR, but will not be the same figure.

Age, height, weight, and gender determine a person’s BMR, also known as basal energy expenditure (BEE). There are multiple formulas used to calculate BMR due to different schools of thought in the health and fitness community. Our calculator uses the Harris-Benedict equation, which works as follows:

If you’re a man, your BMR is equal to: 65 + (6.2 x weight in pounds) + (12.7 x height in inches) – (6.8 x age in years)
If you’re a woman, your BMR is equal to: 655 + (4.3 x weight in pounds) + (4.3 x height in inches) – (4.7 x age in years)

Knowing your BMR can help you create a more effective strategy for weight loss, allowing you to better keep your calorie count on track and better understand the effect exercise will have on your waistline.
