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 ...
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)
There’s no shortage of online calculators for BMRI, but not all are created equal. The Harris-Benedict equation is often used to estimate BMR based on gender, age, weight and height. Once you ...
Basal metabolic rate (BMR) is the rate of energy expenditure per unit time by endothermic animals at rest. [1] It is reported in energy units per unit time ranging from watt (joule/second) to ml O 2 /min or joule per hour per kg body mass J/(h·kg). Proper measurement requires a strict set of criteria to be met.
The raw figure obtained by the equation should be adjusted up or downwards, within the confidence limit suggested by the quoted estimation errors, and according to the following principles: Subjects leaner and more muscular than usual require more energy than the average. Obese subjects require less. Patients at the young end of the age range ...
He even developed a calorimeter large enough to hold twelve girl scouts for an extended period of time. His biggest improvement was the invention of portable field respiration calorimeters. In 1919, Francis Benedict published a metabolic standards report with extensive tables based on age, sex, height, and weight. [21]
