I was told to not doing anything that required severe twisting, but "normal" exercises was fine. I think there are also some extreme amusement rides that should be avoided, but I doubt that would be a problem for you. I was a bit sore until the stitches came out, but after two weeks, I was feeling completely "normal." Minimize any lifting, keep it light until you heal, but everything else was fine.
My docs never did limit my food intake, but I think that was their error.
