The American diet is insane, full stop. However, I've just begun a GLP-1 regimen to address a willpower problem, not a nutritional problem. I'm not quite young anymore and have given lots of other approaches a shot over the years, but have persistently failed to achieve a weight that is not a threat to my health.
So far, what being on a GLP-1 gives me is a steady state that most people probably find quite unremarkable: I don't crave a snack, and I don't thirst for alcohol. Both of those desires have had real control over me for a very long time.
Even if it's not intentional, I find that the enshittification seems to run along these lines.
The things that finally drove it home for me this year were "peppermint bark" and "ranch dip". I used to buy this stuff or use the premade. This year I worked out how to do them properly myself.
People raved about both. But I noticed that they ate far less of them (including myself!). My suspicion is that the difference was that I used actual chocolate and actual buttermilk. I suspect the extra fat made people sated and they quit eating afterward.
I'm finding this applicable to more and more foods. I'm no genius chef, but simply using standard ingredients causes people to eat very differently.
very smart people can rationalize themselves into or out of anything position
