The other issue with BMIs is that they were more geared to male rather than female physiology from the outset onwards and so are not as good a health predictor for females.

The one time my BMI was in the “correct” range, I’d gone on a crash diet to fit into a dress for my friend’s wedding. I was underweight, had low BP, crashed potassium and iron levels, heartburn, and didn’t get my menstrual period for six months. The doctor put me on a gradual weight gain diet and I opted to let my cycle return naturally rather than take hormones. I gained thirty pounds and everything returned to normal including my nearly “obese” BMI.

Many surgeons/hospitals require a very specific BMI for treatments. *Not* a good way of using BMI. A friend of mine needed breast reduction surgery, and was forced to get a BMI below 25. She was an average size M, but she lifted weights and her BMI was 27. She had to stop lifting(!) and also go on a strict diet, to be able to get to 24,9 and have the surgery. She was furious, but had no other option than to play along, in order to get the surgery paid for. Afterwards she had her body composition checked at her gym, and her muscle mass has decreased, while her fat mass was higher than it was before she lost the weight. 😑😖 * If people are very obese, surgery can have added risks. But here we are talking about using BMI 1. As the only metric, not looking at anything else she l about people's bodies and health 2. with a sharp cutoff at the arbitrary 25.

This is not incorrect though, as it is in accordance with research. BMI, as imperfect as it is, is still the most useful and objective tool for estimating someone's risk of adiposity related complications. Every guideline, be it ADA's, AHA's, American Bariatric Surgery Society's, etc, uses BMI as a necessary criteria for certain treatments, because, as flawed as it is, it remains the most objective parameter to calculate the risks and benefits associated with many medical interventions. Consequently, research either on new treatments or on the efficacy of old ones is based on BMI.

As a physician I can tell you that we know BMI by itself is not a good indicator for health. Like anything (including lab results etc) by itself it doesn't mean anything. If someone comes with a low/high BMI the only thing is to figure out if there's anything else wrong and rule those things out. The biggest advantage to it and why we still use it today is because it's free, fast, and easy to calculate. It gives you a snapshot of a person's weight related to their height. Manage of a 30 BMI bodybuilder isn't the same as a 30 BMI pt w/ DM or a 30 BMI pt w/o any comorbids. Think of it as something with high sensitivity but low specificity.

BMI is still used in pharmacology today. As medications are often calculated by weight, in people with high body fat this can lead to toxicity. As these people are underrepresented in clinical studies and there is a lack of study of how to best accurately dose such individuals, the BMI (or only slightly modified version) is often used to make those adjustments, which is inadequate. We owe it to people to do better. To question all our accumulated data for bias and do research into people that have been historically excluded and overlooked

The other problem is that the calculations for BMI quickly breaks down for taller people. It was created using a limited sample size both in terms of race but also in terms of height variation and it did not properly take that into account either. You will be hard pressed to find a person over around 6' that is not at least overweight according to BMI, even if physiologically they are underweight. And since the average height of people has increased so much over the past hundred years that has only made the statistical situation worse. Back in high school I was just under the obese range of BMI but you could see my ribs. When I moved to college and changed doctors, before the first appointment based on the forms I had to fill out, he emailed me and recommended I get more exercise and loose weight, after meeting me he recommended I eat more. He still recommended more exercise.

The only time my BMI has dropped below 20, my ribs were sticking out and my waist was 23 inches. A healthy measure for a woman in my demographic is around 32- granted I have a very dramatic hourglass so my normal is 27. At the time, my liver was damaged and I couldn't absorb fat, my ketones were dangerously high even for a non-diabetic. No matter how much I ate, I could not gain weight. I was 18BMI at my absolute worst, but for most of that period I was 19. Until then, my BMI gave me some serious body dysmorphia- thanks partly to a nutrition class I took in college. Now I know for certain that it's not a number I should even give the time of day to. I was on deaths door, but I was still not technically underweight. Thankfully all of my doctors still treated me as if I were severely underweight, because I looked like I was. I think my primary was considering hospitalizing me so I could get free food and be monitored. A major issue was not having the money for food that didn't make me worse. I credit my recovery to the gomphrena green tea that my sister sent me for my birthday. I drink it everytime I have a flare up, and it always stops it in its tracks. Non specific diagnosis, but I do know the original cause, and what now triggers it. To sum it up if you have a negative reaction to a medication, don't push through it and assume it will stop, even if you get called uncooperative by a doctor, it's better than causing permanent damage and nearly dying. Also recognize food sensitivities and do not take chances. Just slight contamination of some very common foods will set me off.

BMI...how I hated that crap when I was younger. Between 19 and 24 I would regularly hit the gym, and being a mechanic I developed alot of muscle, I was 6ft tall and weight 124kg at the heaviest. My doctor I swear was stupid, would regularly tell me I'm obese, whilst I had a 6 pack and no visible fat on me at all, now year I'm overweight, I'm now 94kg as I'm disabled and unable to do basically anything let alone exercise, my current doctor does say I could lose some weight but it's not urgent, he had some interesting names for my old doctor. Took me ages to actually come to terms I didn't need to lose weight, of course it happened after I could no longer work or exercise.

Good explanation. It was still called Q index when i trained and it was just intended as a population statistic. It was never meant to be applied to individuals. We use waist to height ratio, or abdominal DEXA/MRI/CT for those who can afford it. Visceral fat is a stronger risk factor than pretty much anything else.

In my younger days, BSA (body surface area) was somehow indicative of optimal bloodflow during cardiopulmonary bypass. I don't recall the details, but there was some simple multiplication formula that dictated weight and height times [something] would yield be the optimum bloodflow during cardiopulmonary bypass. I guess it worked fairly well because I ran "The Pump" (cardiopulmonary bypass machine) successfully for several hundred patients. Yes, we had some fatalities but I think they were more a result of pre-operative systemic/cardiac damage rather than than extracorporeal blood flow. In retrospect, "BSA" seems a bit nebulous - but it seemed to do the job at the time.

BMI is great for a quick, basically free, magnitude assessment of the situation. A "perfect" test would be something like a DEXA scan to determine fat content & distribution, then calculating risk based on the distribution. That would also cost ~$150 per measurement In reality, the limitations of BMIs ability to forecast risk doesn't matter. American's have gotten so fat, the risk uncertainty in BMI is completely overshadowed by the BMI magnitude.

It's a very good measure at extremes, but like a lot of statistics, not so meaningful in "the middle of the distribution curve". Patients make a big deal about their BMI being called "high" if they have a slightly elevated BMI of, for example, 27, but an experienced doctor will not think much about this. And there is always the man/women who tells you "it's all muscle"-let me tell you, it's rarely true

Our church took up a collection and paid for the doula. She had little Stephanie at home, AMA. Stephanie is now 29, married, mother of three children, working part-time as a home CNA. My friend is 76, still in good health, just a little arthritis.

Extra fat does increase the risks of surgery. It also means you may not respond as well to hip replacement compared to someone lower in weight, since the surgery is for a load bearing joint.

My BMI is overweight, alledgedly, but I simply CANNOT force my body to lose those last 5 kilos. It will rebel and I find myself driven to eat a lot more to regain the lost weight. I'm not sure why this happens but it's very consistent: at 175cm in height, I can get down to 80kg but no lower, at least not without massive bodily protest. Even if I am overweight (which I think I might be) I cannot fix it without my body very clearly telling me to shut up and stop imposing on it. And it's not like I overeat or anything. 1200-2000 calories a day and I just hang around the same weight, unable to reach that mythically healthy BMI.
@Itried20takennames

So much incorrect information I this video, I may actually make a full on video response on all the misinformation. For one, BMI is a SCREENING test, which are a quicker, easier, cheaper test you can give to most of the popular, to narrow down who should get the harder, costlier definitive test. And because it is the normal and abnormal bell curves overlap, if you set your cut-off to catch all positives, you will also pull in a few normals as well, but for a screening test, “casting a wider net isn’t bad” …if not, you will miss some actual cases. For example, the definitive test for beast cancer is a needle biopsy, but you can’t do that on every woman, in every part of her breast, every year, so you need a screening test for those at risk that will catch the cancer cases as well as some women with lesions that resemble a cancer in some ways, but aren’t…..and that subset should get the definitive test. And that screening test is a mammogram. My Preventive Med Professor would say that “mammograms, as screening tests, aren’t a test for breast cancer…they are a test to see who should get the gold standard test for breast cancer, the needle biopsy.” So a screening test like the BMI are NOT a definitive or “holy grail” test (as incorrectly said here) and are meant to be quick, painless and to see who in the entire population should get the definitive test, which for obesity can be % body fat, or fat impedance, or simply a doc knowing the categories that give a false positive (like very muscular athletes will get a false positive on the BMI.) So this video is also criticizing a screening test for not being 100% accurate, which screening tests never are (that is the definitive test) and complaining of false positives, which unfortunately you HAVE to have in a screening test to make sure you cutoff level does not miss some actual cases. And finally, if not the BMI….then what? Is obesity a 100% subjective concept with no criteria what-so-ever, even in medical circles where where you need SOME quantification method to discuss, stratify risks, facilitate research that saves y lives or even account for height….which the BMI does nicely?

Hey there, it sounds like we agree on the core message of the video: that BMI isn't a perfect tool, but is still useful. Just to clarify, the holy grail line is "These BMI tables are everywhere in health and medical settings here in the United States, *giving us the idea that* a low BMI is the holy grail of health. But of course, nothing is ever that simple". That idea is what made me curious about why the tool was so popular, which allowed me to dig into the history.

According to Google, Dwayne "The Rock" Johnson is 1.96 m and weighs 118 kg. This puts him at a BMI of 30.1, just over the cutoff for "obese". Keep that in mind when you're thinking about BMI. BTW, veterinarians use a scale basically based on judging the animal's silhouette compared to a 1-6 scale (3 is healthy weight, 1 is emaciated, 6 is morbidly obese). I've always wondered why that isn't used more for humans. Though I guess people might get upset if you show them a chunky silhouette and say "this is you".

This causes many people to suffer for longer than necessary just to lose 7 or 10 kg of weight and get below 30, which definitely doesn't make a difference for health risk. And for any plastic surgery in the public health system, they require a max of 25. And we are not just talking cosmetic surgery, but also breast reconstruction after cancer or severely drooping eyelids which cause infections.

Your title and intro suggests that individuals can weigh more than the BMI recommends and is therefore broken. If I look at the comments, you even pinned comments voicing that opinion. The video on the other hand shows that a BMI of 25 is the upper bound for all people, and for minorities it is even lower. It also is an indicator that can predict all cause mortality. So it mostly works and maybe is too conservative.
@PatKellyTeaches

Sorta kinda, there's some more nuance there. It sounds like we agree that BMI can predict mortality at each extreme end of the U-curve (extreme underweight and extreme overweight). My main argument is that BMI is broken because it originated as an average value for an anthropometric measurement, not a health metric, and it failed at the former since its sample was so biased. From there, the application of BMI hasn't been appropriate either since the different categories don't predict disease or death risk equally.

Often when I get VERY LARGE people on the scale that have massive protruding bellies etc up on the scale, their numbers are much lower than I expect because I'm use to weighing myself or similarly fit people. So like this morning, man is 3 times my width, and only 15kg heavier than me. I've been close to his weight at 90kg but the difference is, I was still a lot of muscle where as.... I have no idea what this dude's round belly was filled with.

You keep mentioning "affluent White people" but is there any difference between affluent White people and poorer White people in these studies? Since you only keep saying affluent, have there been any studies of White people who are not affluent and their BMIs based on food scarcity and poverty conditions? I don't think it's fair to simply say affluent White people compared to any and all people of color considering some POC may also be affluent and their access to food could be better than some poor White people's access. Does European country or even region have any factors in how the BMIs would change? Like, are White Americans (of X financial condition) comparably to White Latvians or White Greeks or White English? Is affluent the only thing they factored in? Were males and females separated properly? There's just no rhyme or reason to the BMI, much like the IQ tests that we're finding to be too rigid and formed from only a set sample of people as well (plus multiple types of intelligence so that just being able to see patterns which is what the basic IQ tests mostly cover isn't that great a measure of intelligence in general or even in specific areas).
