I know I will be downvoted into oblivion for this but here goes: Im sorry to be crass but if someone makes lifestyle changes after taking drugs its 100% the drugs.
Kind of tired of people taking anabolic steroids and then claiming it's a smaller part of their success or people being born rich talking about hard work whilst being on the golf course.
Just be happy that we live in a time where drugs have been painstakingly researched and move on without the ego boost. Be humble.
I think it depends on what you mean by "100% the drugs".
I don't think anyone is arguing that the outcome would 100% not happen if it weren't for the drugs, but I think it is useful to note that part of the benefit comes from the habits the drugs help you form rather than simply 100% the appetite reduction the drug produces.
The drugs were a precondition to them being successful in the changes or seeing the level of impact be significantly increased doesn't make it 100% the drugs.
Since you brought up steroids, plenty of people take a gram of gear and look like they don't even lift. I'm not saying that someone taking anabolic steroids should act like they've worked just as hard as someone who is natural and at the same level of musculature, but good results take effort and consistency in the gym, diet, and rest of your lifestyle. You get some benefit just from being on steroids, but and there might be some genetic freak hyper-responders that blow up without any of that, but the overwhelming majority of people aren't going to look like they're a steroid user if they're not pushing themselves very hard as well, and the sheer amount of mediocre physiques from people on gear proves it.
Similarly, if someone turns their lifestyle around with the help of a GLP-1, if they change up their diet from crap to decent or good, if they move from being sedentary to exercising regularly, does the drug get 100% of the credit? Do we throw away all of the other work done?
You can both take a drug and also put in significant work that you can and should be proud of. Both things can be true.

Multi-variate causation doesn't losslessly or deterministically reduce to a single dimension. Particularly when the causes aren't independent.
The drugs facilitate behaviour change. Changed behaviour helps the drugs work. Both done together are stronger than independently, and the strength of that interaction (and the overall effect) is mediated by other inputs.
