The Body Mass Index (BMI) is the ratio of the body mass the square of the height in meters.

\begin{equation} bmi = \frac{m}{h^2} \end{equation}

where $m$ is the body mass en $h$ the height of a person. The BMI is an indication of a person's total body fat and does not measure the body fat directly. It is a moderate correlation with direct measures of body fat. The index can be used as a screening tool for determining whether a person is underweight, has a normal weight, has overweight or is obese. The BMI classification uses the following guidelines: underweight (≤18.5) , healthy weight (18.5–24.9) , overweight (25.0–29.9) , and obese (≥30.0) .
