Sara jane, I lost 16 lbs. my first week post op! I couldn't believe that. I will admit that I cheated pre op and didn't do the diet. I fasted (only water) 2 days prior to surgery to empty my stomach. Since then, I have lost 4 more pounds in 4 weeks. I am eating approx. 1100 calories a day, still pureed or soft. I look forward to meeting you in Nov.
