This seems like one of those "replication crisis" claims.

> That's why they could stop being fat, if only they chose to.

So they're pre-ordained not to?

I have a loved one who certainly chooses to, to the point of having had bariatric surgery; GLPs have been an important follow-up. It's really not as simple as you make it out to be.

> You don't go from 12% obesity to 40% obesity in 40 years due to a genetic shift, but rather a cultural one.

What if that cultural one is letting the processed foods industry engineer everything to be deeply addicting?

> So they're pre-ordained not to?

No. I'm saying it's within their power, so they aren't pre-ordained either way. You were suggesting that it's impossible for a large percentage of the population to not be obese without medical intervention, that it was comparable to excessive acid production which is a genetic anomaly and out of an individual's own control.

> What if that cultural one is letting the processed foods industry engineer everything to be deeply addicting?

Sure, the industry bears some blame and is part of the cultural issue, but even if presented with addicting substances, it is both an individual choice to consume them and a collective cultural choice not to regulate them.
