BMI Method
BMI, or body mass index, is a simple and widely used method for estimating body fat. The method was developed by the Belgian Statistician and anthropometrist Adolphe Quetelet. BMI is calculated by dividing the subject’s weight by the square of his/her height, typically expressed either in metric or US ‘Customary’ unit.
Metric: BMI = kg/m2
Note: In this formula, kg refers to the subject’s weight in kilograms and m is the subject’s height in metres.
The current weight definitions in use establish the following BMI values, agreed in the year 1997 and published in the year 2000.
A BMI less than 18.5 is underweight;
A BMI of 18.5 -24.9 is normal weight;
A BMI of 25.0-29.9 is overweight;
A BMI of 30.0-39.9 is obese;
A BMI of 40.0 or higher is severe (or morbid) obese;
