I am nearly 11 months post bypass.
I don't think there is anything I can't eat, I seem to eat a pretty normal diet. If I am sick, it's usually just from eating too much, or too quickly.
I do dump, but not on the tiniest bit of sugar. I wish I dumped on less.
I don't eat meat so can't comment on that, but I am ok with scrambled eggs and quiches, in fact I love them. I love cheese too.
Recently dumped on ice cream and popcorn (not together!).
