Frederick: The medical world cant recognize that 200lbs can look differently on two different people 6'0" tall.

The problem with BMI is that it's being used by people who don't know any better to determine things that it was never designed to determine.

[standard BMI rant included below]

Basically, BMI is the same as insurance charts with ages.

Statistically speaking, younger folks are more likely to be involved in car accidents. You might be a perfect considerate driver at 18, but the majority of the 18 year olds are retarded jackoffs.

Likewise

Statistically speaking, 26 BMI folks are more likely to have weight related health problems. You might have a perfect trim muscular body, but the majority of the 26 BMI folks are fatties.

*Basically, if someone looks at 10 people and their BMI says that they're overweight, like 9/10 people will be overweight. And the 1 person that isn't is our super muscular body building guy. That still gives an accuracy of 90%, despite the fact that it was totally wrong with the last guy.

*) numbers pulled out of my ass, used as an example

moothemagiccow: I thought taking this into account was the entire point of BMI

You thought wrong, here's the quick and dirty about BMI

1) For generations, doctors collected height/weight/age information from people who went in for checkups. Even back in the days before personal computers, they stored all of this in huge filing cabinets.

2) For generations, doctors also collected disease info about their patients, also written down in files.

3) Somewhere in history, someone looked at a large chunk of this data and started crunching numbers. They figured they could take the height/weight info and calculate some sort of number to classify people into risk groups for disease (Underweight, Normal, Overweight, Obese, etc).

4) Statistically speaking, people in the Overweight group are more likely to have weight related diseases, and people in the Obese category are MUCH more likely to have weight related diseases. This is backed up by the decades and decades of health statistics that doctors collected.

5) The BMI was never meant to be applied strictly to individuals. It was meant as a general guideline to be used across an entire population. You have to use some common sense when you use it and realize that there are going to be some people who lie at either end of the bell curve.

CapeFearCadaver : Regardless, it's still underweight, per usual.

Underweight ... isn't that par for a cadaver?

NotARocketScientist: The BMI site that tmo72 linked said my ideal weight (at 5'8") was 123 - 166. I spent most of my teens and all of my 20s at 125 lbs and was considered a walking skeleton. It was most defiantly NOT a healthy weight.


So then weigh something between 150 and 166.

The broad range takes into account different body types. People grossly overestimate how much muscle they actually have.

littlett's : The problem is that some health insurance want to use that as a means to adjust your premiums. So in my case I'm ok at 112 and 5'7" since I'm underweight. My guy is 5'11" and 190 pounds and is athletic but he is considered overweight by his insurance because of his BMI.

And people under 25 pay more for car insurance, it sucks, but that's insurance for ya.

//5'10", 184, and average ... because I inherited my ancestor's cooking ability.

Sasquach: CSB"
5'6" farker here....in my big weight loss push, I went from 240 down to 160 (BMI 25.8, still overweight). At 160, friends and family convinced me to see a doctor as I looked, in their various critiques , "sickly, weird, creepy, gross, and just not right". My old family doc mentioned my ribs probably didn't need to be showing as much as they were....and to ignore BMI. I puffed up to 180 and made everyone happy again...

/recently ran just over a 4 hour marathon (and hated it)
//not monstrously muscular at all; perhaps I am just dense?


I'm 5'6" at 155lbs and you're in better shape than I am. My brother is built like you, a short thick tank.

BMI works just fine for me. It says I am a little bit over-weight, which I am. I'd be happy to permanently lose another ten pounds.  Of course I'm not a body-builder, am taller than average, and have a moderate to light build, so I fit the model much better than most.

The waist to height ratio is a better predictor of health: you should keep it under half. By this measure, I am still a little bit over-weight and would happily lose another ten pounds.

He fought them over it.  It took him a year but after submitting the results of his physical and a body fat analysis, his insurance provider did finally take off the additional charges for him being overweight.

At 6'2", I don't understand how 150 can be considered healthy. I can see ribs at 180.
 
2013-01-21 04:37:05 PM
For some purposes the relevant health metric actually is weight/height2. Think for example in terms of pressure -- If you double a person's length/width/height and multiply their weight by 8, that'll also double the pressure on all the bones/organs in the body (because the cross-sectional area only goes up by a factor of 4).

When I was born, everyone said "he's built just like his grandfather". I have an awful time finding shirts....anything reasonable in the chest assumes my shoulders are several inches broader than they are. On the upside, I lost my man boobs when I lost the weight. So there's that.

Dude, kudos to you. I went from 230 to 170 in 5 months and later in the year ran a half-marathon. I'm at 190 right now and not happy about it... 180 needs be my max.

Anyways, I wanted to reply to say KEEP IT UP. I know how hard it is to hear people's comments. You know you want to lose that last 15 lbs and you have people telling you to look "sick". It's frikkin irritating. Keep it up and losing as much as you did, even if you went a few lbs beyond your "max healthy" weight, is a great accomplishment, and it's night to have some wiggle rooms so that a big weekend doesn't throw you into "overweight" territory again.

Is this where a bunch of fats say their bmi isn't fat it's just big boned?

Yeah, they like to use BMI because insurance people are all about statistics. In their mind, it doesn't matter if he's healthy, he's subsiding the costs a bit for someone with the same BMI who is even unhealthier.

Just another reason to believe that BMI is based on junk science.

Boomerang: Five years ago I was 5'5" and 155 pounds - and Jacked.

Now, I am the same height, the same weight, and Fat.

Life is funny.


Maybe all that jacking was keeping the fat off?  What, did you have like a huge right arm?

SacriliciousBeerSwiller:

I love how critics of these labels like to use pro athletes who are in the peak of human fitness as counterpoints. With a BMI of 31, unless you too are a pro athlete with a 6-pack and an Adonis body, then sorry, you're just fat.


I'm am by no means a pro athlete, and my Doctor told me at my last physical that the ideal BMI for my body type is 30.

The last time I got my BMI below 25, my family accused me of having an eating disorder.

I'm with you on that. At 230lbs, yes, I was a bit heavy, but not obese (I liked my beer a little much), but BMI stated I was borderline. At 175lbs and 6'1" I'm considered borderline overweight, yet I'm starting to freak out. My face shouldn't look like a skull, or my ribs like a famine victim.

Isn't in flippin amazing/irritating how little food it takes to maintain this weight? I do 30-40 minutes of HARD cardio every damn day, keep my calorie count way down just to maintain this...

Going from a fat guy to a much less fat guy has been great for oh so many reasons....I don't want to go back!

I'm not entirely surprised by this at all.

/I sound short and fat

For 6'1", BMI gives 141-189 as normal weight. 175 is not borderline anything for that height.

The midpoint of the "normal" range is 165.

Obese starts at 228 pounds, people mistakenly think that "obese" == giant huge person with fat flops, but medically obesity is classified well before those visuals are present. And at 230 that was just slightly over the cusp anyway.
