BMI isn't the best, but I don't think there is a single way to measure "health" that would deem her healthy.

---

My bmi is 21 but i felt healthiest at 19.4 bmi

would u like a reddit one instead

She's right, I don't need to know her BMI to have a general assessment of her health.

---

Fucking disgusting.
Fat fucks like her who try to make obesity a non-problem are just as bad as anti-vaxxers.
It is NOT healthy to be morbidly obese.

---

BMI is pretty shit if you go by the whole 'it's absolutely' but if you're like 50overweight like her then no, it's pretty fucking obvious that being super-obese is unhealthy

I had to watch it twice because her ripples kept mesmerizing me

---

It's certainly not perfect. If your BMI is like 27 or so you are technically overweight, but you can certainly be healthy at that range. But if your BMI is like 35 or something and you aren't a bodybuilder then you probably need to lose some.

It's a metric meant to measure populations, not individuals.

but regardless of metrics visceral fat is unhealthy. That is fat that surrounds your organs. If you have a beer belly, you have visceral fat. She seems to be a beer belly with a head and limbs poking out. Her pancreas is screaming. Her kidneys cry out. But her metabolism just sits there and says "no."

Of course it's a rotund af person lol

BMI is inherently flawed but Ive never met a healthy person complain about it.

That bitch is OBESE.

Modern day body builders seem to have early deaths as well. I don't think someone at 5'11" is supposed to be 330 pounds even if it is all muscle.

While Tiktok isn't exactly the right source to be getting this kind of info from, the claim itself is pretty close to correct.

---

It's a meaningful metric in more than 80% of the population. The top 5% are incredibly muscular are are better off by a bf% test. The bottom 15% are "skinnyfat" and have normal BMI but at-risk BF%.

It's supposed to be a quick and dirty test, lmao.

Suspending that bitch in water via Archimedes method would also warn her about a looming health crisis.

then why do people take it as a meaningful measurement of someone's health?

Because the average person is not a medical expert and doesn't really need to know the intricacies of things like this. They should be consulting someone who is a medical expert for that - or if they really insist on DIY'ing it, at least doing proper research instead of trusting word-of-mouth from other non-experts or just going along with "something they heard" without looking into the full details.

I feel like it's accurate enough if you're an average person who doesn't go to the gym that regularly.

This.

Most of the people that call it a "flawed" measurement like to talk about the top 5%.

I like to joke with my wife about how Saquon Barkley and myself are both 6-foot and weigh 234 pounds, so we're basically the same person, body-wise.

She seems to disagree.

Morbidly obese girl tik toks about bmi being bad.

Thats the entire joke.

of course it's a fucking fatass in the vid

How I used to do it was to strip myself naked and jump up and down. Parts that weren't suppose to move means that it's fat.

That camouflage isn't working

because it's correct 80% of the time; it's good enough any anyone with a middle-school education can both perform the test and interpret results.

Most people who dislike what BMI tells them will also dislike what a more rigorous, expensive, and time consuming test will ALSO tell them -- or they're bodybuilders/athletes.

dividing your weight by the square of your height is not a "test"

whether or not they'll like it has absolutely no bearing on whether or not it, on its own, is a meaningful metric for overall health.

Completrly useless. Lebron james is obese according to bmi. They dont take into consideration muscle mass.

Good thing it's not used on its own as a meaningful metric for overall health by actual professionals, so there's no reason for you to make this argument other than to discredit BMI based on strawmanning it.

There is a big dark side to the fitness industry, that's for sure.

Steroids are a huge part in bodybuilders dying young, it is not a secret that pretty much all professional bodybuilders are on steroids, and the vast majority of fitness models too. The drugs themselves obviously have really negative side effects on all sorts of organs, but like you said, people are not meant to walk around as a 300 lb brick house w/ 6% bodyfat, and would never get that big naturally no matter how much you lift. Very stressful on the heart, which kills a lot of young bodybuilders.

Plus the nutrition supplement market is a free for all, you can sell the craziest shit w/ almost no oversight.

it can be used in conjunction with other metrics and tests to give a reasonable picture of overall health. but those other metrics give a reasonable picture of overall health without bringing BMI into it at all

---

BMI is generally a good guideline.

Yeah when you're teetering between categories you gotta take into account muscle mass and etc

So you understand how its used and you still tried to discredit it by lying about how its used.

Yeah, being that heavy for a long time isn't particularly great for you. You'll see a lot of NFL linemen lose weight when they retire since that body type isn't good for you long-term.

Bodybuilders die early because of the steroids. To quote a great legendary bodybuilder: "if i die at 50 i die at 50. But im gonna look great in the process."

you're half right. I do understand how it's used. I did not, however, lie about how it gets used.

namely:
https://en.wikipedia.org/wiki/Body_mass_index#/media/File:Correlation_between_BMI_and_Percent_Body_Fat_for_Men_in_NCHS'_NHANES_1994_Data.PNG

So, my bad. 75% of the time, BMI is good enough. 16.5% of people are in better health than BMI suggests, and 8.5% of people are worse than BMI suggests.

BMI opponents like the chick in the OP are not a member of the 16.5% crew.

See also:
https://deepstrength.wordpress.com/2015/08/30/bmi-overweight-and-attractiveness/ which cites 18% of men and women being "misread" by BMI, with 12% of men and 3% of women clocked in as "healthy obese".

the graph you linked correlates BMI with body fat percentage, not with "better" or "worse" health

What do you propose is a good snapshot for health, if not one's BF%?

I propose that there isn't a single metric that provides a good snapshot.

but that aside, the fact that BMI correlates with Body Fat percentage (which I'll concede may be useful in conjunction with other metrics) does not mean that BMI itself is a useful metric.

as far as correlation with "overall health" goes though, off the top of my head I would suggest grip strength or vegetable consumption. both correlate more strongly than BMI with general health
