The body mass index (BMI) also known as the Quetelet index, offers a relationship between the height and weight of a person. It was devised by the Belgian Adolphe Quetelet. BMI is represented as the body weight of an individual in kilograms divided by the square of the height in meters. The BMI serves as a useful objective unit to discern the extent of obesity in an individual.
Body Mass Index (BMI) is a formula to calculate relative body weight. BMI is essentially a co-relation of height and body weight. It is calculated as the weight in kilograms divided by the square of the height in meters. This determination of the amount of fat and lean body mass gives an indication of a person’s weight. A body mass below 20 is considered underweight; about 21-25 is normal; about 25-29 is overweight; and if your BMI is over 30 then you are obese. A BMI greater than 40 qualifies as morbidly obese.
