Calculate...What?

So, what is a BMI and why should we calculate it?  The BMI, or body mass index, is a do-it-yourself method to estimate your body fat.  Combine BMI with waist size and you have a good indicator of your risk for certain health problems such as cardiovascular disease and diabetes.

I have done this measure before, but it has been a really long time, and I approach it with some trepidation.  

Here is the formula to figure it yourself:

BMI = (weight in pounds/(height in inches X height in inches)) X 703

There is also a waist to height ratio that, combined with the BMI, is fairly accurate at presenting a picture of your health.

WHtR = waist in inches/height in inches

The calculator used at Real Age factors both together.  Following is a link to that calculator.

Rather than re-hash all the information that abounds on this topic, I will add a couple of links for further reading.

BTW, my index is sobering-ly high.  Someday when it is a smaller number, I'll share what it was today.
