Body fat mass index (BFMI) is a measure of body fat based on height and weight. It is calculated by dividing the weight in kilograms by the square of the height in meters. For example, a person who weighs 70 kilograms and is 1.75 meters tall would have a BFMI of 22.86.
BFMI is a useful tool for assessing body fat levels. It is more accurate than other measures, such as body mass index (BMI), which does not take into account body composition. BFMI can be used to track changes in body fat levels over time and to identify individuals who are at risk for obesity-related health problems.
