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.
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.
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.
Basal metabolic rate (BMR) is the calories your body burns at rest. ... To calculate your BMR, you should use the Mifflin-St. Jeor equation, which is the most accurate. ... (5 x age in years ...
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]
Taylor thus defines metabolic age, as, θ = λ t A − 0.27 {\displaystyle \theta =\lambda tA^{-0.27}} where A {\displaystyle A} is the standard adult body weight in kilograms t {\displaystyle t} is the time from conception λ {\displaystyle \lambda } is a dimensional coefficient that depends on the units of time being used
The metabolic equivalent of task (MET) is the objective measure of the ratio of the rate at which a person expends energy, relative to the mass of that person, while performing some specific physical activity compared to a reference, currently set by convention at an absolute 3.5 mL of oxygen per kg per minute, which is the energy expended when sitting quietly by a reference individual, chosen ...
An individual's BMR varies greatly with age: infants and children typically have a high BMR, required for growth, while the elderly have a low BMR. [1] Tall, thin people have a higher BMR than their shorter counterparts, even with the same weight, due to the greater surface area of their skin. [ 3 ]
