BODY MASS INDEX

What is Body Mass Index?

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.

What is your BMI?

BMI	Classification
<19	Underweight*
19-25	Healthy range
25-29.9	Overweight
30-39.9	Obese
>40	Morbidly obese

*Underweight does not necessarily mean unhealthy!

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) ÷ Your height² (in meters²)

Or you can use the following table...

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!

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

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