BMI: Body Mass Index

Body Mass Index (BMI ) is a measure of body fat based on height and weight that applies to both men and women. It is a reliable calculation, however it does have some limits: It may overestimate body fat in athletes and others who have a muscular build and/or it may underestimate body fat in older persons and others who have lost muscle mass.

Use a BMI calculator to estimate your total body fat (see link below). Your BMI score will determine whether you are underweight (below 18.5) , normal weight(18.5 - 24.9) , overweight (25.0 - 29.9) or obese (30.0 and above).

If you are considered obese or overweight, you should speak to a doctor to see see if you are at risk of developing diseases associated with obesity and/or should lose weight.
