I had my gastric sleeve on Nov. 17. 1 week pre-op diet I lost 20lbs. 1 week post op diet I lost 10lbs. Right after surgery I started full liquids on direction of my doctor. I will be 4 weeks out on the 17th of December and I have not lost another pound since the end of the first week post-op! As a matter of fact, I have actually gained 2-3 lbs! I transitioned to pureed food, eat about 60 grams of protein and 800 calories. Well I dropped a couple of pounds so i hope I am on my way! I am drinking as much water as i can, usually 64 oz. I too was frustrated about my 2 1/2 week stall! I hope the weight starts falling off! When i said i eat 800 calories, i usually end up throwing up.
