A way to make BMI useable

(Carmelo Signorello) #1

When I listened to 2ketodude’s Richard explained how BMI was designed. While the intention was good, it was extremely easy to see where the results are not reasonable since we are all different. So I played with the numbers to come up with a score that works and is reasonable and consistent.

So what I found was if you divided BMI by your body weight fat a score of .55 to .60 would be normal. The closer to 1 the more fit you are. The closer to 0 the more obese you are.

Example 1 (normal male 5’10” 165lbs body fat 25%)

BMi is 23.7 and Body fat weight is 41.25 (23.7/41.25= .57)

Example 2 (Male same height 262 lbs 19% body fat)

BMI is 37.6, body fat weight is 49.8 (37.6/49.8= .76)

Example 3 myself 5’11 262lbs 36.1% BF.

BMI 36.5, body fat weight is 94.6 (36.5/94.6= .39)

Example 4 Normal male 5’10” 262lbs body fat 25%

BMI 37.6, body fat weight is 65.5 (37.6/65.5= .57)

This method would seem to put a correlation to body fat weight and not based off of volume.

Let me know what you think.

Thanks,

Carmelo

This makes sense, but I’m wondering: if you have access to your body fat percentage, why have another number that’s based on that? BF% is a pretty clear measure of most of what we’re looking for when using an index for weight/height/fat.

Exactly… Bodyfat will tell you most of everything you need to know.

I like waist:height ratio. Can be measured yourself and takes lean mass into consideration. Simple and effective.
