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. [4]
TDEE is the number of calories you need to maintain your current weight based on your activity level. From there, you can adjust your calorie intake to create a deficit for weight loss. For ...
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.
A body composition analyzer is a device that assesses your BMI, muscle mass, and body fat. You may feel healthy, but you can still have fat build-up. I got a body composition analysis, which shows ...
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).
The Estimated Energy Requirement, , is the estimated number of daily kilocalories, or Calories, an individual requires in order to maintain his or her current weight. For a person with a body mass of m {\displaystyle m} (kg), height of h {\displaystyle h} (m), age of a {\displaystyle a} (years) and Physical Activity PA {\displaystyle {\text{PA ...
BMI vs. Body Fat Percentage. BMI and body fat percentage are both ways of determining whether a person has a healthy weight or not. A high BMI can indicate a high body fat percentage, but it’s ...
