What is BMI?

Body mass index (BMI) is an international measure used to calculate whether a person is in the ideal weight. This index was developed by polymath Lambert Quetelet in the late nineteenth century. It is a fast and easy method for evaluating the level of fat of each person, that is, an international obesity predictor adopted by the World Health Organization (WHO).
