In both the formulas given above, W is body weight (kg), H is the height (cm), A is age, and F is body fat (%)Īccording to a study, the Mifflin-St. Most of the BMR calculators also rely on the Mifflin-St Jeor Equation. It is one of the most popularly used BMR formulas. Harris-Benedict formulated the first equation to find BMR and revised it in 1984. That is because different researchers have come up with different formulas and methods to calculate BMR. However, with advanced research, people use several formulas to do so.

Although BMR is a standard of physical well-being, it is unique for your body, typically depending on your age, height, weight and gender. Studies by the International Journal of Obesity suggest an accurate estimation of BMR to be critical for the rigorous development of obesity control and prevention strategies. Similarly, increased body fat will have a decreased metabolic rate or a reduced number of calories burnt during rest. Therefore, it is directly proportional to the type and intensity of the physical activity you engage in daily.Ĭhanges in the BMR such as increased physical activity or muscle mass will increase the number of calories burnt during minimal functioning. Your BMR primarily depends on involuntary functions like breathing, digestion, pumping blood and reflex actions. You can think of it as the amount of energy your body needs to burn these calories. Whether you’re sleeping, talking on the phone, working in your office, or watching TV, your body keeps burning calories.

Like several other calculators, including BMI and calorie calculators, the BMR calculator also plays a vital role in improving our efforts to get fitter and maintain healthy body weight. However, most of us do not know the importance of calculating BMR. Many of us on our fitness journey must have heard the term BMR Calculator.
