You say this - but not from experience (correct me if I'm wrong and you have taken a GLP-1 agonist).
I say this because as someone who has taken it, I found one of the craziest parts is how they do seem to help you set better habits, and those habits do stick, and it's not like some fake thing.
For example MJ helped me do the following: entirely stopped late night snacking, stopped craving sweets, stop smoking weed. And it doesn't come back when I go off, even after months.
I wasn't especially overweight when I went on (maybe 20lbs), I did it for the incredible immune system benefit which seem to heal my immune disorder, but I was stunned at the results outside of it.
I get that people hate the idea of something that helps you be better without having to "put in work", but in the weirdest and best way possible, it seems to do that, at least in part.
