BMI is calculated as weight in kilograms divided by the
square of height in meters. But wait - don't let that scare you off. For those of us who are not metric savvy, there's another easy way to figure BMI. Just pull up a calculator and follow along:
First, figure your height in inches, then multiply that
number by itself. So if you're 5' 5", for instance, you're
65 inches tall; 65 x 65 equals 4,225.
Next, divide your weight by that number. So if you weigh 150 pounds, divided by 4,225, that equals .0355.
Still with me? Now, one last step: Multiply that last number by 703. In the case of our example that equals 24.95, and that's your BMI.

Isn't the BMI scale thing kind of flaky? If your a big guy with a really low BF% your BMI is still going to say overweight or even obese.
Mine was 21 by the way. And my friend scored a 27 which should mean he is overweight, but his six pack says otherwise (what a bastard :P)

A BMI of 18.5 to 24.9 is normal. Overweight is 25.0 to 29.9. And a BMI of 30.0 or above is considered obese.
****note, these numbers are not from me. Just a calculation I found that I thought may help folks out. I do consider the source fairly reliable though.

I got 25.1% I am 5'10", 175 pounds. (Not cool to hear I am "overweight" by .1%)
I think I am going to try the BMI on mybodycomp.com to see how close this number is to what they come up with.

I ask because body building must skew a normal bmi. My bmi by the formula is 28. My BF is approaching 15. I know I'm not fat.

Ron did you get that from Draper's page? I saw that thier in the newsletter. It makes sense, but again, the number is to be used as a guide, right? tape measure, and bmi and scale is best and if all are relative, then we are ok.

Yes, this was just a post for those kind of just starting out, with not much muscle who are interested in finding their BMI to work from without having to do algebra or something. It of course does not take muscle into account, just posted it as a help for new folks. Sorry guys, didn't want to lead anyone to thinking they were OBESE!!
And, Carivan, no that is not where I got this. It was in a health letter I receive, has nothing to do with bodybuilding.

The place I found this was for using to figure risk of Alzheimers for male and female. Here is the "full" text.
A recent study suggests that if you're carrying a few extra
pounds, you may significantly reduce your chances of
developing Alzheimer's disease (AD) by working off those
pounds and keeping them off.
And the key is your body mass index.
--------------------------------------------------------------
The new math
--------------------------------------------------------------
You've probably heard of body mass index (BMI), but do you
know what yours is?
BMI is calculated as weight in kilograms divided by the
square of height in meters. But wait - don't let that scare
you off. For those of us who are not metric savvy, there's
another easy way to figure BMI. Just pull up a calculator
and follow along:
First, figure your height in inches, then multiply that
number by itself. So if you're 5' 5", for instance, you're
65 inches tall; 65 x 65 equals 4,225.
Next, divide your weight by that number. So if you weigh 150
pounds, divided by 4,225, that equals .0355.
Still with me? Now, one last step: Multiply that last number
by 703. In the case of our example that equals 24.95, and
that's your BMI. And if that really IS your BMI, then you're
at the high end of the "normal" zone.
A BMI of 18.5 to 24.9 is normal. Overweight is 25.0 to 29.9.
And a BMI of 30.0 or above is considered obese.
These BMI ranges are used to determine relative risk for
certain diseases such as type 2 diabetes. And according to
recent research from Utah State University (USU), women who
have BMIs in the obese range or the upper end of the
overweight range may be at considerably higher risk of
developing Alzheimer's disease as they age.
--------------------------------------------------------------
Men get a pass
--------------------------------------------------------------
Because previous trials have shown that vascular factors may
contribute to Alzheimer's risk, and because obesity puts a
strain on the vascular system, USU researchers wanted to
examine the association between AD and obesity.
Almost 400 subjects with no signs of dementia, aged 70 to
80, were followed for 18 years. During that time,
neuropsychiatric tests were conducted and BMI was routinely
measured.
At the end of the test period, researchers found there was
no statistical correlation between BMI and Alzheimer's risk
for men. In women, however, the association was significant.
On average, women who developed dementia tended to have a
BMI about two to three points higher than the women who
remained mentally healthy. All of the averages in the
dementia group were in the middle to high end of the BMI
overweight range.
The researchers concluded with this rule of thumb: At age
70, each 1.0 increase of BMI may raise AD risk by 36
percent.
The results of this study are significant in light of the
obesity crisis in Western countries. The Alzheimer's
Association projects that by 2025 more than 22 million
people worldwide may be diagnosed with AD. And if the USU
research is correct, the current obesity trends will rise
hand in hand with upward AD trends.

I saw a special on BMI the other day on the news and it trashed it. It doesn't account for extra bone or muscle density (e.g. heavy-boned people or muscleheads like us). Best thing to go by is bodyfat, calculated several ways, then averaged, imo.

Yah I got a 31, but in no way consider myself Obese. I am over weight however. I am 5'7" and 200lbs and about 20%BF. At 175lb ish I would be quite lean.
I think for a person of 5'7" I have a bigger frame than most, and this would be why I'm put up in the Obese level.

Goldengloves, keep at it man, and you will get up there! When I started into workingout about 4 yrs ago I was at about 210, and pretty inactive (right after Highschool, stopped playing Hockey) I dieted down to about 160lbs and was pretty lean, I would guess about 10% I could see the top of my abs. Then I started to Bulk for about a yr or so, and I know I've added some size to my frame, My arms are 16" Flexed. But then I started to slack off for about a year or more, and I'm at my current Size, now I just need to lean out ;)

The key is right in the title: Body MASS Index. For those of us that are above average in mass, we get hit with a label that does not care if that mass is muscle, bone, or fat (or a gosh dang butt tumor for that matter).
And BMI is relatively not related to Body Fat.

2004/02/19, 12:02 PM
Ogun I agree because I think I got the other way around. I have a "normal" BMI but I KNOW that I have a high body fat content.
I guess BMI means nothing to me... is that wrong? I got a 21 on the BMI... 5'8" and 135lb. So what? Yeah, this might be encouraging me that I'm not "obese" but I still don't fit into a size 8!! I don't think the BMI takes into account the size of a person's butt. haha
Seriously speaking, what is the point of a BMI?

I too would like to know what BMI would mean to someone?

I don't want to say it means nothing. It's a general indicator created by the NIH that one would use for a ballpark figure on where he or she stands. It can't accurately apply to pregnant women, athletes, or people who have lost large amounts of muscle mass.
But it's almost a picture of an ocean, whilst you and I are concerned with the shape, size, and color of a coral reef. It's simply to broad, and could be misleading.
