BMI (Body Mass Index)
Body Mass Index is one measure of obesity (or non-obesity). It is a measure of body fat that is the ratio of the weight of the body to the square of its height.  A body mass index that exceeds a value of 28 for a man and 27 for a woman is often used as an indication of obesity.
