Body fat can be estimated from body mass index (BMI), a person's mass in kilograms divided by the square of the height in meters; if weight is measured in pounds and height in inches, the result can be converted to BMI by multiplying by 703. [26] There are a number of proposed formulae that relate body fat to BMI.
In 2008, 35% of adults above the age of 20 years were overweight (BMI ≥ 25 kg/m 2), a prevalence that has doubled worldwide between 1980 and 2008. [112] Also 10% of men and 14% of women were obese, with a body mass index (BMI) greater than 30. [113]
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 ...
Compared to traditional metrics, such as the body mass index (BMI), (which uses weight and height), BRI may improve predictions of the amount of body fat and the volume of visceral adipose tissue. Despite its common use, BMI can misclassify individuals as obese because it does not distinguish between a person's lean body mass and fat mass ...
Anthropometric data such as height may be recorded in centimeters. [91] The body mass index (BMI) is expressed in kg/m 2, even though it may be computed from pounds and inches. Even if the medical practice takes height and weight data in terms of SI units, it is almost always discussed with the patient in terms of customary units.
Using the body mass index as a measure of weight-related health, with data from 2014, age-standardised global prevalence of underweight in women and men were 9.7% and 8.8%, respectively. These values were lower than what was reported for 1975 as 14.6% and 13.8%, respectively, indicating a worldwide reduction in the extent of undernutrition. [6]
People are classified as obese when their body mass index (BMI)—a person's weight divided by the square of the person's height—is over 30 kg/m 2; the range 25–30 kg/m 2 is defined as overweight. [1] Some East Asian countries use lower values to calculate obesity. [11]
