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.
Basal metabolic rate (BMR) is the calories your body burns at rest. ... Women: (10 x weight in kg) + (6.25 x height in cm) - ... While it is possible to slightly increase your BMR by building ...
Calculate your BMR: 655 + (9.6 x weight in kg) + (1.8 x height in cm) - (4.7 x age in years) It’s also important to note that men typically have a higher BMR than women.
The basal metabolic rate accounts for about 70% of the daily calorie expenditure by individuals. It is influenced by several factors. In humans, BMR typically declines by 1–2% per decade after age 20, mostly due to loss of fat-free mass, [3] although the variability between individuals is high. [4]

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 observations that, for a vast number of animals, an animal's Basal Metabolic Rate scales to the 3 ⁄ 4 power of the animal's mass.
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. [3]
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 .
