Discrepancy between BMI and Body Fat Percentage
Has anyone ever measured there Body Fat Percentage? I did the measuring one the other day, where you measure your wrists and your waist and thighs and such, and there's a huge discrepancy. And, I was wondering if anyone else can relate.
I took both the U.S. Army and the U.S. Navy formulas. I find the U.S. Navy formula slightly more believable. According to the USA Format, I'm at 33.65% body fat, and the U.S. Navy formula is 44.30%.
Which gives me a BMI waist-to-hip ratio of >1.2. To be an obese man, it's over >.9 and on a woman it's >.85.
According to the Army formula, this gives me a lean body mass of 191.6 lbs, and the U.S. Army formula is 160 lbs, which I find more believable.
But if I were to believe these numbers, basically I BARELY qualify to be obese in terms of Body Fat Percentage, and yet my BMI shows that I am most severely obese, that is to say 38 BMI or Class II Obesity (Severe Obesity).
The thing that puzzles me is: Maybe I measured wrong, but I DO have thin extremities, like I have small to medium wrists for a man: 7 inches. I can wrap fingers around and do all the stuff that very thin people can do with their wrists.
And, when I get to 260 lbs, things like my collar bones stick out prominently, and I have a thin face and legs, which leads many when I get to around 260 to say that I'm "no longer fat", just a bit pudgy, and I will get comments on how I'm thin and that I can eat whatever I want and all this. It gets weird.
Bottom line is, does anybody else have mismatched measures like me. I don't lift weights or anything, and I can't claim to be "big boned" with my wrists, lol. But is it really possible I could have a lean body mass of 191 lbs?? or even 160? (which I find a more believable number). I don't rule out that I could have more muscle than I realize simply because it takes muscle to lug around this much weight.
So basically: anybody else? And, how do I stack up to others in terms of body fat percentage? I dunno normal, and it's hard to google this information.
