It feels more likely to me that there's some sort of condition we don't have a widely known name for that is caused long-term by a combination of predisposition in genetics and something in western diets that is, I'm not sure, forcing us to overproduce ghrelin (possible links to puberty occurring earlier in both young boys and girls?), or underproduce certain classes of incretins (possible links to excessive blood sugar levels in larger percentages of the population historically over time?).

It would be boring to learn that it's just caused by excessive exposure to fructose.

But what do I know, I'm just a dumb HN reader.

Seems neat that there's ongoing work in this area and it'll be cool to read about new knowledge in that space when something is discovered.
