*Another tip is to stay in the sun. The data on sun exposure has largely reversed over the last decade; sun exposure is positively correlated with improved health outcomes, but should be done in moderation as to prevent skin issues.

Where "moderation" means something like 15-30 minutes[1].

That link says

> In general, scientists think 5 to 15 minutes -- up to 30 if you’re dark-skinned -- is about right to get the most out of it without causing any health problems.

Yes. And people tan waaaaaaaaaaay more or work outside.

It turns out that food is also healthy for you, in moderation. Alas, we need a drug to help us moderate.

[fnord77]

yes, because historically, food has been so scarce that we never evolved a shutoff mechanism on our own.

I don't disagree with your premise, but I also don't fully agree with it as a comprehensive explanation. Overeating seems to be a uniquely American problem, and independent of a nation's food security status. For example, the obesity rate in Japan is much lower than that of the US and I don't think that's due to them (a) not having enough food to over-indulge or (b) somehow having evolved a shutoff mechanism that Americans have yet to develop.

To me, it seems almost entirely explained by culture.
