Body Mass Index (BMI)
It's a method devised by the Belgian statistician Adolphe Quetelet. It's the most commonly used method for calculating overweight and obesity. It is obtained by dividing the weight in kilos by the square of the height in meters (kg/m2).
The BMI is not a data that applies to everyone, it should not be used as a reference in pregnant women, children, elderly and people with great muscle development as athletes.
