The Harris–Benedict equation (also called the Harris-Benedict principle) is a method used to estimate an individual's basal metabolic rate (BMR).. The estimated BMR value may be multiplied by a number that corresponds to the individual's activity level; the resulting number is the approximate daily kilocalorie intake to maintain current body weight.
How To Calculate Your BMR. There are a few different ways to calculate BMR. Getting an exact and totally accurate BMR requires a DEXA scan, says Lombardi. “This is essentially a picture of your ...

Basal metabolic rate (BMR) is the rate of energy expenditure per unit time by endothermic animals at rest. [1] It is reported in energy units per unit time ranging from watt (joule/second) to ml O 2 /min or joule per hour per kg body mass J/ (h·kg). Proper measurement requires a strict set of criteria to be met.
The Schofield Equation is a method of estimating the basal metabolic rate (BMR) of adult men and women published in 1985. [1] This is the equation used by the WHO in their technical report series. [2] The equation that is recommended to estimate BMR by the US Academy of Nutrition and Dietetics is the Mifflin-St. Jeor equation.
Generally, TDEE calculators estimate BMR based on a person’s height, body weight, age, and sex assigned at birth. Then, they use a physical activity multiplier with the BMR. Then, they use a ...
Kleiber's law, named after Max Kleiber for his biology work in the early 1930s, states, after many observation that, for a vast number of animals, an animal's Basal Metabolic Rate scales to the 3⁄4 power of the animal's mass. [2] More precisely : posing w = mass of the animal in kilograms, then BMR = 70w kilocalories per day, or BMR = 3.4w watts.
Some of the most popular and accurate equations used to calculate BMR are the original Harris-Benedict equations, the revised Harris-Benedict equations, and the Mifflin St. Jeor equation. [19] The original Harris-Benedict Equations are as follows: BMR (Males) in Kcals/day = 66.47 + 13.75 (weight in kg) + 5.0 (height in cm) - 6.76 (age in years)
