Taller people are heavier. If you’re not adjusting for that your data will be funny. Guess what, if you adjust for that using the square of height you’ve invented raw BMI. The categories are probably arbitrary, but you don’t need them, and a different exponent will generally show the same trajectory if by different magnitudes.
Although come to think of it, the population got taller, so the trend would be even stronger if we weren’t factoring that out.
I’m willing to change my mind too, and I do indeed have a lifetime of exposure to media and experts behind this, although I don’t believe in conspiracy theories which seems to be what you’re suggesting by a certain ideology being pushed.
That’s a fun paper, because they basically find no actual negative health effect, then just ignore that fact and continue as if they did.
First, the global focus on the obesity epidemic has largely overshadowed the persistence of underweight in some countries. Our results show the need to address the remaining underweight problem
Second, although adiposity has been consistently shown to be an independent risk factor for several NCDs in individual-level epidemiological studies, at the population level, the effect of rising BMI on the course of mortality reduction has so far been somewhat small in high-income countries
All the study shows is that as people get richer they can overcome being underweight, which is an incredibly good thing - it reduces health risks significantly. Then it goes back to the usual moral panic shit about how that’s actually a bad thing.
Essentially everything you ever heard about weight and fat is ideological, not scientific, in basis. Research consistently finds results that aren’t statistically significant, then just blathers about how that statistically significant result would exist if they could account for x y z. There’s no scientific basis to the claim.
The basics of it are that extremes on either end, of being underweight or very overweight, are health risks. The health risk of being “overweight” are massively overstated, because people like to judge and bully fat people.
Second, although adiposity has been consistently shown to be an independent risk factor for several NCDs in individual-level epidemiological studies

Yes, being poor and starving still sucks. Nobody cares because it happens outside of the magic Western bubble, but that’s another issue for another thread.
I think I’ve proven my point here, so I’ll just duck out.
Yeah, because the individual-level studies aren’t worth shit, that’s the point. They’re like the scientific level of analogies. You get these studies that are on like, 15 people or whatever that make some statistically significant finding, then it later turns out that they either very selectively chose their test subjects, the methodology was a complete joke, they p-hacked the findings into worthlessness or all of the above. If the individual level studies scaled up, if they were actually finding something real, they would be reflected in population-level studies. The fact that they aren’t pretty clearly demonstrates that there isn’t a strong correlation.
Low weight is a significant health issue in wealthy countries too. It’s a massive contributor to mortality rates, as much as high adiposity is. But it’s not discussed because it’s less popular to bully people for being skinny as it is to bully people for being fat.
But sure, I’m the one who refuses to change his mind when challenged.

Here’s the first paper that comes up, using BMI, about the exact breakdown of how it increased: https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(16)30054-X/fulltext
