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.
There are two commonly used equations to calculate BMR: Harris-Benedict equation . Mifflin-St. Jeor equation . The Mifflin-St. Jeor equation is considered more accurate and is more widely used, ...
Basal metabolic rate (BMR) is the rate of energy expenditure per unit time by endothermic animals at rest. [1] ... The revised Harris–Benedict equation. In 1984, ...
While less exact, studies show online calculators using the Harris-Benedict equation take into account your height, weight, age, and gender to give you a rough assessment of your BMR. Since the ...
Harris-Benedict equation Katch-McArdle equation Generally, TDEE calculators estimate BMR based on a person’s height, body weight, age, and gender assigned at birth.
However, it is also possible to approximately estimate BMR using several equations that factor in a person's age, sex, height, and weight. [18] 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 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 ...
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.
