I did not know that! My dr, basically tells us that we can eat what we want , just eat all a serving of Protein first, which as most know, doesnt leave much room for else! I do eat my Proteins before anything else that i usually dont have any room left. But the few local gals i know that have had the procedure done said they have not done a special diet. I was hard core atkins before i had my surgery and it worked pretty well, I had a lap band in at the time, for 10 years actually and I lost more when i would atkins than with the band itself. The band wouldnt let me eat meat so eventually, I decided to have the revision done and get the sleeve. I really did not realize that i would be on low carb the rest of my life. Its a little sad but too late now ESPECIALLY if i want to see some results. Makes me feel like i should have done more research and just gotten my LB taken out instead of the full on sleeve procedure.
