A Biometric Study of Human Basal Metabolism. The difference between the equations shown above and those on the Daily Caloric Expenditure Calculator is illustrative of the actual meaning of BMR. In the Daily Caloric Expenditure Calculator, BMR was multiplied by the "Activity Level Factor" to account for daily physical activity levels and the thermic effect of food (thereby providing an estimate of the total amount of calories you burn in a day), but these factors are not a consideration when determining BMR. The equations above are exactly the same as those used for our Daily Caloric Expenditure Calculator, except that the "Activity Level Factor" that is used for the Daily Caloric Expenditure Calculator has been removed here. for man (metric) : BMR 10 weight(kg) + 6.25 height(cm). Male (imperial): BMR = (6.25 x WP) + (12.7 x HI) - (6.76 x age) + 66 With this equation, the Basal Metabolic Rate (BMR) can be calculated with the following formula.Male (metric): BMR = (13.75 x WKG) + (5 x HC) - (6.76 x age) + 66 Basal Metabolic Rate (BMR), Total Daily Energy Expenditure (TDEE), and Body Mass Index (BMI) Calculators and Tools.Some alternative methods to BMI, including the waist-hip ratio, are discussed in our article, 5 alternatives to BMI.This calculator is based on the widely used and accepted Harris-Benedict equations for BMR. For this reason, BMI is not an indicator of obesity on its own. So, someone who has a very muscular physique (a body builder, for example) may have a high BMI without having excess fat. It is important to remember that BMI measurements do not make a distinction between whether you are male or female, whether you have a large or small body frame, whether you have high muscle mass and the areas in which fat isĭistributed around your body. Reference: The practical guide: identification, evaluation, and treatment of overweight and obesity in adults - National Institutes of Health (NIH), National Heart, Lung, and Blood Institute (NHLBI). The first component is got by multiplying 9.563 with weight in kilograms. BMR formula For men: (4.536 × weight in pounds) + (15.88 × height in inches) - (5 × age) + 5 For women: (4. Using a BMI calculator such as the one on this page, you enter your weight and height measurements.īelow are the BMI classifications for men and women established by the World Health Organization (WHO) and endorsed by leading organizations of Using this formula, the BMR of a female is calculated using three components. Your BMR is calculated by entering your height, weight and age figures into the BMR formula. The body mass index calculator measurement is the calculation of your body weight in relation to your height and is commonly used as an indicator of whether you might be in a risk category for health problems caused by your weight. Interactive BMI chart is also available to use. Learn more about how to use these formulae with our in-depth article on the BMI formula. The official formula for BMI was devised in the 1830sīy Belgian mathematician Adolphe Quetelet.
