This is a measurement of body fat using a calculation of your height and your weight.
If you are less active, body fat gradually replaces muscle. Extra body fat increases the risk for heart disease.

BMI alone is not diagnostic. It is one of many risk factors for developing a chronic disease (such as heart disease, cancer and diabetes). As a person's BMI increases the risk for many diseases increases as well.
Other factors that may be important to look at when assessing your risk for chronic disease include:

  • Diet

  • Physical Activity

  • Waist Circumference

  • Blood Pressure

  • Blood Sugar Level

  • Cholesterol Level

  • Family History of Disease


To calculate your BMI:

Your BMI = Your weight (in kg) χ Your height2 (in meters2)

CAUTION!


BMI calculations are not valid for children under 18 years of age, or for muscular people or athletes. Someone who is very strong but lean will still weigh a lot. Their BMI will therefore be high, but they are not obese!
