i'm not in pharma but i've done some research when it started gaining traction to see what it is

ozempic and other glp-1s tend to be a life long treatment, people who go off it regain weight, have blood sugar surges etc.

there are also negative side effects of burning off that much fat in your body that quickly and ppl are getting the ozempic face since the weight loss is so rapid. body stores toxins in fat so by burning a lot of it you will release lots of toxins in your system which means that you should be also working on getting rid of that (and you might feel like crap).

in any case its a very one sided approach that highly reminds me of the fatkins from cory doctorws Makers novel where people do gene therapy to get their bodies to burn 10000kcal/days in order to lose weight (and later on figure out there are some long term effects of this)
