BMI isn't perfect, but it's also been the subject of relentless attempts to discredit it from movements like Healthy At Every Size (who are actively trying to kill people by spreading the belief that there are literally no negative health effects for even the most severe obesity) so I'm always suspicious when people dismiss it off-hand. Yeah, if you have the ability you should get a DEXA scan and have a much more accurate view of your body fat level, but unless you are an honest-to-god elite athlete the number you get back from the DEXA scan is going to be in the general range that your BMI suggests. You're not going to have a BMI of 30 with just 10% body fat unless you're Arnold Schwarzenegger when he was competing in Mr. Olympia.

Accuracy of Body Mass Index to Diagnose Obesity In the US Adult Population See here and here for the definitions of the measurements they're using. The tl;dr is that BMI is not suitable tool for diagnosing obesity as measured by excess body fat. It may have value when combined with other measurements, but then you have to look at whether those other measurements are fine on their own.

ultrafilter posted:Accuracy of Body Mass Index to Diagnose Obesity In the US Adult Population That study has been posted ITT before, and it's important to note that their conclusions about BMI's limits are specifically because it gives too many false negatives, as many of the study participants were obese as defined by their body fat levels but had a BMI lower than 30. Study Conclusion posted:Despite the good correlation between BMI and BF %, the diagnostic accuracy of BMI to diagnose obesity is limited, particularly for individuals in the intermediate BMI ranges. A BMI cut-off of ≥ 30 kg/m2 has a good specificity but misses more than half of people with excess fat. These results help to explain the U and J-shape association between BMI and outcomes. So yeah, BMI is very limited. But if your BMI is >=30 the odds that you don't have a large excess of body fat are basically the same odds that you make at least $400k a year, because you're in the top 1% (and are probably already well aware of it well before you stepped on the scale).

1% of the general population with a BMI over 30 is not obese, but among people who run/lift/do anything athletic the proportion is going to be higher. I don't believe the NHANES III contains data about activity levels so they can't measure those subpopulations.

I don't believe the NHANES III contains data about activity levels so they can't measure those subpopulations. I mean, the proportion will be higher in that 0% of people with a BMI at or above 30 who do not do any regular physical activity but somehow don't have excess body fat. Like, unless some person got into the study who secretly swallowed a bunch of lead weights that's just not how the human body works. Because fat is such an emotional topic in our culture, people go to great lengths to delude themselves about how much body fat they have. I've seen guys whose bellies literally fall over their belt say with 100% conviction that you can practically see their abs (what you could actually see was the way the indent of their belly-button created folds along their mid-section). Hell, I definitely deluded myself in the past ("I'm a competitive strongman, this is all muscle!"), and it was only by getting regularly measured through DEXA scans that I was able to see through those delusions. And you need to be able to see through those delusions if you want to make real progress. (Well, that an a Wegovy RX. That poo poo is loving amazing.) By the way, even as I'm typing this now I'm still obese. I've lost 100 pounds since my all-time-high weight, and I work out 3-4 times a week, but my BMI is just about 32 and my body fat percentage is around 27%. At the risk of deeply embarrassing myself in the 'POS, I've actually got progress pictures that show me at various levels of obesity. (All taken immediately post-workout at the same gym over the course of 2 years. The most recent one was from this last Thursday.)

Good going, Lance - you got a little extra at the waist on me but otherwise looking pretty much the same shape / weight / BMI. Keep it up. I felt that I was coasting a little with my workouts the last month or so, so last week I stepped up an extra plate on each of the cable machines I use, and yeah that's brought things back into the realm of 'Actual Effort', wasn't getting a'pump' before but now I am. I'm going to to try and not get complacent once this new weight gets to be as easy as the last step and keep pushing myself. I was worried about mounting up the 28kilo dumbbells for my 45degree bench presses up from the 26s without dropping / stalling them, and then it turned out actually that was pretty easy, I might challenge myself to the 30s next time drat if I didn't get some warning 'pre-cramp' twinges from my biceps when in the shower afterwards and lifting my arms up to wash my hair, will have to watch out for that.

as bad as BMI is, I decided to start cutting in part because I was getting really close to "obese" on that scale.

i asked my doctor's office if we could get a more accurate measurement of my body fat % than bmi and they hmm'd and ha'd and said "I haven't heard of us ever doing that" kthx

big shtick energy posted:BMI cops a bad rap because it's not super accurate but it's an attempt to take a stab at a persons risk of having excess adiposity using the crappy measurements that a health professional can easily make. And it does okay in terms of being a medical test at the extremes, in that if your BMI is below 18 or above 35 chances are your bodyfat level is out of whack enough to be a significant health risk. But yeah if you go overboard and say that someone with a BMI of 24 is just fine (they might still have enough excess adiposity to have health risks) or that someone with a BMI of 26 should be on a TLC special (they might be just fine) then that's obviously silly. bmi was created in the 50s for insurance purposes op

yeah, but that's a very different matter, if we're trying to figure out how many people are statistically facing health problems in a population of a million bmi is probably a pretty good stab at it (and was probably better still in 1950 when the extremes were less extreme). that does not make it a good measure for one person to apply to themselves though.

Yeah, insurance companies need to know two things to function:

yeah maybe some insurance companies. but not american health insurance companies, they just skim off the top of government enforced oligopoly "markets" and can earn more money purely by jacking up rates in a way that literally nobody can follow or understand

The frustrating thing about this argument is that the people working hardest to discredit BMI don't actually give a poo poo about accuracy of measuring body fat. Bring up things like getting a DEXA scan and they'll go all shocked-pikachu that the option even exists and then just change the subject. It's just a bullshit motte-and-bailey argument meant to hide what they really want to say...

Obesity has plenty of negative health consequences and BMI is a bad metric It’s bad because it doesn’t distinguish muscle from fat

oh well. I'm losing weight and BMI, the lovely metric that it is, will tell me I'm "normal" soon. and also, I look better in a medium size shirt instead of large now.

LanceHunter posted:Okay, I guess there is also a second category of the argument... lmao for real, whenever i see somebody jumping up and down about bmi being terrible, i think of the keto thread from like 2008 or whatever it was. like, no poo poo it's not an actual in-depth analysis. it distills fatness down to a single number, and its inputs are height and weight. anybody who would expect that to be flawless is just, like, kind of dumb. watching people discover that it's not infallible (and then decide it's the worst thing ever) is like watching nerds discover food that isn't chicken tenders, and then proceed to tell everyone about ramen like it's the most delicious exotic food imaginable. or that time when someone (tori maybe?) started eating vegetables and didn't shut up about it for months because he assumed that nobody else had figured out how to eat like an adult before 35 which is to say, it's cute at first but it gets old eventually Achmed Jones fucked around with this message at 17:38 on Jan 22, 2024 |
