You might think that these two (get skinny and lower Alzheimer's risk) are the only two benefits, but don't forget that this drug is also pretty much the end of the road for the "More People Should Be Fat!/HAES movement".
Agreed. I'm down for being empathetic to fat people - as a fat person! - but I have never understood the movement to just deny reality and act like it's acceptable to be fat from a health perspective. Obviously fat people should still have access to healthcare, but putting our heads in the sand and pretending that it isn't a situation that has huge impact on our quality of life and lifespan has always struck me as absurd.

And good riddance I say!
