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.
A high BMR is often associated with a fast metabolism and greater muscle mass, while a low BMR can hint to a slower metabolism, lower muscle mass, and higher percent of body fat, says Carmichael ...
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]
The difference in BMR for men and women is mainly due to differences in body mass. For example, a 55-year-old woman weighing 130 pounds (59 kg) and 66 inches (168 cm) tall would have a BMR of 1,272 kilocalories (5,320 kJ) per day. The revised Harris–Benedict equation
Women tend to have more body fat than men, even if they have the same BMI. Body fat can also differ between races, ethnicities and ages — older folks tend to have more body fat than younger ...
In males, mean percentage body fat ranged from 23% at age 16–19 years to 31% at age 60–79 years. In females, mean percentage body fat ranged from 32% at age 8–11 years to 42% at age 60–79 years. But it is important to recognise that women need at least 9% more body fat than men to live a normal healthy life. [2]
Men also carry more skeletal muscle tissue on average than women, and other sex differences in organ size account for sex differences in metabolic rate. Obese individuals burn more energy than lean individuals due to increase in the amount of calories needed to maintain adipose tissue and other organs that grow in size in response to obesity. [ 2 ]
Though BMI is often used to help assess for excess weight, it is not a perfect representation of a person's body fat percentage. For example, an individual can have a higher than normal BMI but a normal body fat percentage if they have higher than average muscle mass. This is because excess muscle contributes to a higher weight.
