How much of the data was done independent and how much was done by the same company or companies that benefit from it? We've seen this before. How many decades did people take aspirin thinking it was good for you to take everyday. How many decades did people drink wine thinking it was good for you in small dosage? How many people smoked using it as an appetite suppressant not knowing the long term effects?
The list goes on forever. I'm betting this ends the same way.
How much data do we have on obesity and the effects of it?
Dude, the mortality rates go up at least linearly, maybe super-linearly, to weight over a certain amount. It's not like some mythical / hard to read / later benefit. This is a drug that radically changes those risks NOW, really quickly. It's a different matter than aspirin (helpful if heart disease is a real risk, otherwise no) or wine or smoking, both of which people have a strong interest in thinking of as good for you.
