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.
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]
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

This free software had an earlier incarnation, Macsyma. Developed by Massachusetts Institute of Technology in the 1960s, it was maintained by William Schelter from 1982 to 2001. In 1998, Schelter obtained permission to release Maxima as open-source software under the GNU General Public license and the source code was released later that year ...
The Harris-Benedict equation is for determining neutral energy balance. If a person were provided with 100 calories per day by their body fat and not replenishing it, they would be losing weight, in negative energy balance.
