Can you keep the weight off once you stop using it? I don't particularly want to have my personal health be in the hands of one company especially if the culture stratifies into those who can afford to be the right weight and those that can't. Especially when it enters it's "enshittification" stage.
It's hard to keep weight off once you stop using it, but I've not seen anything to suggest it's harder to keep it off if you lost using GLP-1 than if you lost the weight the normal way. Most fat people I know have lost weight successfully more than once "the hard way" and then regained it.
