Reducing Cardiac Risk: Determining your Body Mass Index
What is body mass index?
Determining how much you should weigh is not a simple matter of looking at an insurance height-weight chart, but includes considering the amount of bone, muscle, and fat in your body's composition.
The amount of fat is the critical measurement. A good indicator of how much fat you carry is the Body Mass Index (BMI). Although it is not a perfect measure, it gives a fairly accurate assessment of how much of your body is composed of fat.
To calculate your BMI manually:
- Take your weight in pounds and divide by 2.2 to determine your weight in kilograms. This is your "weight number.
- Next, convert your height in inches into height in centimeters by multiplying the number of inches by 2.54.
Now, divide your weight number by your height number.
- Divide your height in centimeters by 100 (there are 100 centimeters per meter).
- Next, square your height in meters by multiplying the sum by itself. This number is your "height number."
A BMI between 25-29 is considered overweight. Anything over 30 is considered obese.
