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 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 ...
The Dietary Reference Intake ( DRI) is a system of nutrition recommendations from the National Academy of Medicine (NAM) [ a] of the National Academies (United States). [ 1] It was introduced in 1997 in order to broaden the existing guidelines known as Recommended Dietary Allowances ( RDA s, see below). The DRI values differ from those used in ...
The Institute of Medicine Equation was published in September 2002. It is the equation which is behind the 2005 Dietary Guidelines for Americans and the new food pyramid, MyPyramid . The Institute of Medicine equation uses a different approach to most others. The equation doesn't measure basal metabolic rate, but uses experiments based on ...
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.
Partner sex may take a bit more energy, but you're still only burning around 4.2 calories a minute, according to a small study done by scientists at the University of Montreal in 2013.
Social aspects. v. t. e. A caloric deficit (also known as calorie deficit, in British English calorific deficit) is any shortage in the number of calories consumed relative to the number of calories needed for maintenance of current body weight ( energy homeostasis ). A deficit can be created by decreasing calories consumed by lower food intake ...
