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.
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
The metabolic cost of transport includes the basal metabolic cost of maintaining bodily function, and so goes to infinity as speed goes to zero. [1] A human achieves the lowest cost of transport when walking at about 6 kilometres per hour (3.7 mph), at which speed a person of 70 kilograms (150 lb) has a metabolic rate of about 450 watts. [1]
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 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.
National political correspondent Maggie Haberman suggested earlier this week that there would be “zero cost” for Vice President Harris to skip the annual Al Smith dinner.
