![]() ![]() Instead, the new findings suggest the body size and mass of the cells significantly matter to calculate BMR. However, in 1984 this equation was revised and proposed that age and gender really don’t matter in BMR evaluation. The Harris-Benedict Equation for calculating the basal metabolic rate of males and females isīMR (male) = 66.4730 + (13.7516 x weight in kilograms) + (5.0033 x height in centimeters) – (6.7550 x age)īMR (female) = 655.0955 + (9.5634 x weight in kilograms) + (1.8496 x height in centimeters) – (4.6756 x age in years) Many people are more physical than others day, thus a better estimate of daily calorie usage is provided in this manner which is better calculated using this formula. In this equation, the caloric needs of the individual are estimated using the basal metabolic rate and then adjusted according to how much the person is physical during the day. However, owing to multiple reasons this formula is not considered valid.Įven though it has its drawbacks, the Harris-Benedict Equation can nevertheless be beneficial. In their book, they proposed the Harris-Benedict equation that takes into account the gender, age, weight and height of the individual. Benedict collectively in 1919 proposed the first formula to calculate the BMR. The scientific equations that are derived, in order to calculate BMR by taking the individual’s physical variables, in a BMR calculator are explained below. Lean body mass is a measure that appears in more complex equations to estimate BMR. To determine BMR, scientists have created several calculators based on one's gender, age, weight, and height. Still, most people lack the means to receive an indirect calorimetry test. While testing BMR in a lab requires strict conditions like the postabsorptive state measurement that entail things like spending the night in a lab and getting tested just after you've had eight hours of sleep. Indirect calorimetry is used to determine your exact BMR in a lab environment. Accordingly, you can adjust your diet and perform physical activities in order to burn surplus amounts. The BMR calculations are also used for weight management and diet control techniques.įor instance, to determine how many calories your body requires in order to sustain life, you can manage your calorie consumption. However the BMR calculations are not only restricted to medical needs, it can also be used for personal health evaluation as well. Doctors often recommend this test in order to evaluate underlying health issues. ![]() The calculation of the basal metabolic rate is required for the identification of various health conditions. The BMR accounts for the rate at which the basic functions like the brain, lungs, heart and other visceral organs working take place. The least amount of energy we need to carry on basic functions of life is known as the Basal metabolic rate. ![]()
