Hi
I guess it depends on what you are eating now!
How big your mouthfuls are and what your portion sizes are are going to have to change.
But, if you can eat it in a tiny mouthful at a time there doesn't seem anything you can't eat, but you have to realise that you won;t be able to eat a normal plate serving again, you will leave at least half of a normal serve on your plate and if you forget to eat in tiny portions you may be bringing it all up again because the band is so uncomfortable.
Look, it takes forever to learn not to munch away and take a big bite - not to keep pace with friends and their eating pace and to make wise food choices. Ice cream, chips, wine etc etc will always fit, chocolate will always fit, a good mouthful of a sandwich or burger will go down but you may regret it immediately when you feel uncomfortable.
In a way it is " All things in moderation" once the band has been adjusted to restrict the stomach.
Good luck
Cleo
