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.
The Harris-Benedict equation is often used to estimate BMR based on gender, age, weight and height. Once you have your BMR, multiply it by an activity factor to determine your total daily energy ...
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)
Several equations to predict the number of calories required by humans have been published from the early 20th–21st centuries. In each of the formulas below: [19] P is total heat production at complete rest, m is mass (kg), h is height (cm), a is age (years). The original Harris–Benedict equation
Kleiber's plot comparing body size to metabolic rate for a variety of species. [1]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.

An older but commonly used and fairly accurate method is the Harris-Benedict equation. Yet, there are currently ongoing studies to show if calorie restriction to below normal values have beneficial effects, and even though they are showing positive indications in nonhuman primates [ 14 ] [ 15 ] it is still not certain if calorie restriction has ...
