What is Body Mass Index (BMI)?

Body Mass Index is a measure of body fat which can be used to estimate whether a person is underweight, overweight or within the healthy weight range for their height.

It is a useful measurement as people outside the healthy weight range for their height can experience greater health risks than those whose weight is within the healthy range.
