The referenced formulas used to calculate the BMR are listed below. However, anaerobic exercises, such as weight-lifting, indirectly lead to a higher BMR because they build muscle mass, increasing resting energy consumption. On an average around 50% to 75% of the daily energy expenditure is attributed to the resting metabolic rate. Muscle Mass Aerobic exercises, such as running or cycling, have no effect on BMR. If you what to calculate the daily calories intake requirements depending on how much exercise you get, check out the Calorie Intake Calculator for a more accurate estimation of your daily caloric intake needs. When trying to improve your body composition and body fat percentage, you must reduce fat mass and gain muscle. Jeor equation, you’ll need to use one of two equations: Males: 10 × weight (in kilograms) + 6.25 × height (in centimeters) 5 × age (in. Multiply that by the conversion, and you get 2,602.45, which is how many calories this person needs to maintain his weight. To calculate your BMR/RMR using the Mifflin-St. If you know your body fat percentage, lean body mass can be calculated by the following formula: (1 - Body Fat Percentage / 100) x Weight. A restful state refers to the energy sufficient only for the functioning of the vital organs: the heart, lungs, nervous system, kidneys, liver, intestine, sex organs, muscles, brain and skin. Using the Cunningham equation, this person would have a BMR of around 1,679 Cal/day.

It is measured in kilo joules per hour per kilogram of body mass.Īs humans, we burn up energy around the clock regardless of what activity we undergo (that includes sleeping), however the BMR calculation does not take into account any type of additional physical activity other than a restful state of the body. The BMR Calculator measures your Basal Metabolic Rate (BMR) that represents an estimate of calories burned while resting - also know as resting metabolic rate (RMR).
