You may find that there are some foods that you cannot tolerate because of your band, but you will learn what they are over time and it may vary according to the level of restriction that you have. It also depends on what your provider says you should or shouldn't be having. Mine enables us to eat any foods that we wish, however, Im limited to a certain amount of cals per day, and from personal choice limit my carbs with a high protein diet as it aids weight loss. The only thing I have struggled with so far is pork, but other than that, I haven't encountered any problems and although I've had 2 fills I have yet to find restriction from my band.
PLease don't worry, while things may change, there isn't a whole long list of foods that you won't be able to eat, but a lot of it is down to your own personal choices for healthy eating and losing weight moving forward
