Gastric Bypass Surgery Information

I have tried to look it up and I getting almost every link but the one that tells you what you can and can’t eat and the number of meals per day. Does anyone know? I know with lap band it’s 2 oz per meal 6 times a day. List of the do’s and don’t s foods are to long to list, but point is I know about the lap band. I am asking about the gastric bypass.
Thanks for your help
