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.
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).
Kleiber's plot comparing body size to metabolic rate for a variety of species. [1]Kleiber's law, named after Max Kleiber for his biology work in the early 1930s, states, after many observations that, for a vast number of animals, an animal's Basal Metabolic Rate scales to the 3 ⁄ 4 power of the animal's mass.
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 ...
Benedict's reagent (often called Benedict's qualitative solution or Benedict's solution) is a chemical reagent and complex mixture of sodium carbonate, sodium citrate, and copper(II) sulfate pentahydrate. [1] It is often used in place of Fehling's solution to detect the presence of reducing sugars and other reducing substances. [2]
Software of unknown pedigree (SOUP) is software that was developed with a unknown process or methodology, or which has unknown or no safety-related properties. [1] In the medical device development standard IEC 62304, SOUP expands to software of unknown provenance, and in some contexts uncertain is used instead of unknown, but any combination of unknown/uncertain and provenance/pedigree refer ...
"nor does it account for the additional calories provided by excess body fat" This is wholly irrelevant. If one is provided with 100 calories per day by their body fat, then they must eat another 100 calories per day to maintain their body fat. The Harris-Benedict equation is for determining neutral energy balance.
The Benedict–Webb–Rubin equation (BWR), named after Manson Benedict, G. B. Webb, and L. C. Rubin, is an equation of state used in fluid dynamics.Working at the research laboratory of the M. W. Kellogg Company, the three researchers rearranged the Beattie–Bridgeman equation of state and increased the number of experimentally determined constants to eight.
