My question is... what are life span of keeping the weight off? I read on someone's post that it is 5yr sleeve vs 15yr on a bypass.

My research doesn't support that...for one thing, the sleeve is a relatively new procedure, especially compared with RxY bypass...only in recent years has the sleeve been performed routinely, so there couldn't possibly be a valid 15-year success rate yet for the sleeve...what I have read is more such that it's believed the success rate will be very similar for the bypass v. sleeve

I can eat all day long and just barely reach 1200 calories, I think the people who gain again are the ones who eat nothing but fattening and sugary foods and the ones who overeat.
