No, it's because you can get the same result, plus other ancillary benefits, by simply stopping the behavior causing the issue.
Imagine smokers rambling they can't stop smoking because bad tobacco put addicting chemicals in their cigs. Just put that shit out already, right? Same for food. Eating for survival =/= the american diet.
Processed food is bad, and everywhere. Ok. What are you going to do, take semaglutide and then eat the same shit, but a bit less? Or are you going to switch to healthier food? Then why don't you switch now and skip taking a medicine for the rest of your days?
GLP1 is a drug to heal the lack of willpower, not to heal the body.
