What is so different about this than a doctor telling you that this statin will help to lower cholesterol, but if you stop taking it, the cholesterol will come back?
Or a doctor saying that this PDE5 will make your dick hard, but if you stop taking it, you'll go back to having a limp dick?
I kinda get what you're saying...but what doctor in their right mind would use that as a reasoning against statins and boner pills?
I think a couple of important things need to be realized...one being that there are a ton of factors that play into obesity.
If you want to cure obesity, it needs to be done at a societal level. You have to be Socratic about it. Nobody ever gets past the first easy "but why" to "what causes obesity."
Doctors realize this about statins, and they prescribe diet and lifestyle in tandem with statins. Why they can't apply the same methods to obesity baffles me.
