Using BMI to Calculate Required Weightloss
Everyone has heard of body mass index (BMI) and except in muscular people it takes ones height and produces an appropriate weight range…
Normal is considered 18.5-25… Over 30 is obese.
Calculating BMI is relatively straight forward… Where W is weight in pounds and H is height in inches then (703 is a conversion factor from the metric system):
[W ÷ (H)2] x 703 = BMI
Well given that my BMI was 40.8 at my initial visit I decided to figure out what my weight should be based on the BMI calculation… For that I applied some of my high school algebra to produce the following equation:
W=(BMI ÷ 703) x (H)2
Given that I am 6′10″ or 82 inches… Here are the various range boundaries…
| BMI | Weight | |
|---|---|---|
| Current | 40.8 | 390 |
| Obese | 30 | 287 |
| High Normal | 25 | 239 |
| Low Normal | 18.5 | 177 |
By a strict definition I would have to get to 239 lbs to no longer be considered overweight…
