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.
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. Then, they use a physical ...
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 ...
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
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)
The most popular formula is the Mifflin-St. Jeor equation which calculates your BMR. For women, the Mifflin-St. Jeor equation is: BMR = (10 x weight in kg) + (6.25 x height in cm) – (5 x age in ...
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 ...
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]
