Females: 10 × weight (in kilograms) + 6.25 × height (in centimeters) – 5 × age (in years) – 161įor example, a 35-year-old, 200-pound (90.7-kg), 6-foot (183-cm) male would have a BMR/RMR of 1,882.Males: 10 × weight (in kilograms) + 6.25 × height (in centimeters) – 5 × age (in years) + 5.Jeor equation, you’ll need to use one of two equations: To calculate your BMR/RMR using the Mifflin-St. However, BMR and RMR are often used interchangeably, and calculating your RMR should get you a pretty close estimate of your BMR. BMR is more restrictive and measures calories with zero movement in the day. RMR determines the calories you burn at rest with minimal movement. Technically, this equation calculates your resting metabolic rate (RMR), which is slightly different from BMR.

Jeor equation is a popular way to calculate it quickly. However, since most people do not have access to these devices, researchers have developed more convenient methods of calculating BMR.

Indirect calorimetry involves using an in-office device that measures the exchange of oxygen and carbon dioxide in your body.

However, it’s typically used only in research settings and is difficult to access. It involves spending time in a tightly controlled room, known as a calorimeter, with little to no movement.

Direct calorimetry is the most accurate method.If you’re looking for the most accurate number, then you’ll want to visit a clinic that offers direct or indirect calorimetry: Your BMR can be calculated using direct calorimetry, indirect calorimetry, or a quick math equation.
