I agree with this take 100%. But also, anecdotally, I do know a number of people who saved enough on their grocery bill to pay for their GLP1. But whether that applies across the whole population, I've no idea.

I'd guess a majority of people could save more than enough in groceries just by planning meals and making an effort to budget instead of going on autopilot to afford GLP-1 drugs. Heck, I'd bet a majority of households eat way too much fast food and restaurant meals, and just doing things on purpose would mean hundreds of dollars a month per person in savings.

"Doctors recommend this one simple life hack to revolutionize your grocery budget!" Or something like that.

GLP1 confounds things with the psychological impact as well; it apparently allows for more executive agency, disrupts the impulsive behaviors and cycles people get into, and might allow for some high discipline strategies that the simple calories difference in groceries don't account for.

It's not that there's no interesting questions to be asked, this paper is just awful. Everything about it is bad.
