Si I'm near the end of me 10 day liquid protein diet. 4 days in I was down 8.5 lbs...all water weight I assume. Now at day 9 and the last couple if days its actually creeped back up about 1.5 lbs. My head really does understand the physics of all this, but I can't help but worry that I won't loose any weight with this surgery. I mean if "drinking approx 500 calories a day won't produce steady weight loss then I don't know what will!

Pre op diet to to shrink your liver, not much more. If you loose wt great, if not no worries its not to drop tons of weight. You WILL loose after surgery. Any time you deprive your body of food, it want to hold on to its reserves, just takes time for your body to adjust. Dont sweat it.
