I was wondering how you could get such a high impact overall. But it seems one in 6 households are on GLP-1 drugs in the US.
In my friend circle in Germany I don't even know one single person on this stuff.
It's insane to me that so many people need these to get off the processed foods killing them in the US.
This is not to say you are wrong. The food supply in the US is not healthy. The bad news is that the same greed that destroyed our food will find ways to get around the ways GLP-1s work.
Weird that it virtually did not exist pre ww2 and that it now affects 75%+ of your population
We know that people just have different metabolisms, different levels of hunger response, different levels of "food noise," etc.
We see obesity rates raising in nearly every country across the world as economic power and access to ultra-palatable hyper-calorie dense food increases. This is universal across the developed world with very few exemptions - Japan seems to largely be immune, but Korea and other portions of Asia aren't.
The growth curves look very similar, despite many of these cultures across the world putting even more emphasis on discipline and responsibility than America, things that in theory directly align with being more responsible about diet. If genetics weren't involved and it was all willpower (and where does the capacity for willpower come from? Is there no genetic component to it?) we wouldn't see these growth trends be so similar to America and each other.
