    BMI or BODY MASS INDEX is a simple calculation to determine if your body falls into the healthy weight range for your particular height.  To calculate your BMI simply divide your weight in kilos by your height in metres squared.
    ie  BMI = Weight
                    height x height
                    eg   ___6o kg__    
                             1.65 x 1.65          = 22
    A BMI classification is intended for adults over 18.  A BMI less than 18.5 is considered underweight, 18.5 - 24.9 us Healthy weight range.  25 - 29.9 is Overweight and Over 30 is Obese.  Note that a BMI may overestimate weight classification in very muscular people such as footballers.

    The Body Mass Index is a calculation that explains where your weight sits, whether you're a normal weight or overweight. It applies to people of the age from 25 to 65. It is also not useful in the very short or the very tall.
