What is BMI?

The body mass index (BMI) or Quetelet Index is a measure for assessing weight relative to body size of a person.


It was developed by Adolphe Quetelet in 1871.

Obesity is a growing problem worldwide and BMI is primarily used as a reference to this danger.

BMI refers to the ratio of weight relative to body surface, estimated from the square of height.

BMI is only a rough estimate because it does not take into account the proportion of adipose tissue and muscle.
