Body Mass Index (BMI) is a number measure which compares a person's weight and height. It was invented between 1830 and 1850 by the Belgian polymath Adolphe Quetelet during the course of developing "social physics".BMI can be used to indicate wether you are overweight, obese, underweight or normal.
