How To Calculate Your BMI
We Are Eating Ourselves To Death! 27.2% of US adults, aged 20 years and over, are obese! Obesity is defined as a Body Mass Index of 30 or more or 20% or more above your recommended weight.
National Health Interview Survey, 2009
To calculate you BMI: take your height (in inches) and square it. Then divide that number into your body weight (in pounds). Then multiply by 703. To make it easy, just click on this LINK.
Underweight < 18.5
Normal Weight 18.5-24.9
Very Obese 35.0-39.9
Morbid Obesity Over 40
Now the BMI can be deceiving at times, as it does not actually measure the percentage of body fat, it is used to ESTIMATE a healthy body weight based on a person’s height.
For Example: I’m 6 ft tall (72”), square 72 (72×72) = 5184 and I weigh 184 lbs. Divide: 184/5184 = .035494 then Multiply: .035494 X 703 = 24.952282 – Which barley places me in the Normal Weight category, yet I’m very fit and most of the weight I carry is lean muscle mass.
However, if you know that you are not in the best shape, the BMI is a very good tool and is an excellent way to monitor your overall health.
