How to calculate Basal Metabolic Rate (BMR)
Basal Metabolic rate is the rate at which the body uses energy while at rest to maintain vital functions such as breathing and keeping warm. Your BMR is the amount of energy you expend each day when at rest.
It's important to note that men and women have different formulae for Basal Metabolic Rate (BMR) calculations. This is due to the fact that men have a higher percentage of lean body weight than women. For the BMR calculations below, we're referencing the Mifflin - St Jeor formula. Calculate your BMR by using one of these formulae.
BMR for men
BMR (metric) = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5
BMR (imperial) = (4.536 × weight in pounds) + (15.88 × height in inches) - (5 × age) + 5
BMR for women
BMR (metric) = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161
BMR (imperial) = (4.536 × weight in pounds) + (15.88 × height in inches) - (5 × age) - 161
BMR calculator allows you to calculate not only the number of calories you burn when inactive but also a daily calorie figure that takes into account your lifestyle activity level.
