I had a RNY gastric bypass Sept 2010, and two years later I still think it was the best thing I have ever done. I went from 265lbs and 40+% body fat to 160lbs 20% fat! I feel great - no major complications, just lifestyle adjustments. I chose abdominoplasty after, as I had a pannus left, but needed no other cosmetic procedures. I lifted weights regularly, walked several miles each night, and played judo a few times a week post-op, so I think the rate at which I lost is most likely not achievable for everyone.
