Ok, if you're only eating Soups that you're not getting full on what you're eating. Coz it slides through your band. Your band isn't even getting the chance to work.
It's one thing to not be able to eat pizza or bread or chips (you realise pizza and chips probably shouldn't be an 'everyday' food if you're trying to lose anyway right?), but quite another if you weren't able to eat fish or grilled chicken or soft cooked vegetables.
Because with the band, you could easily eat a whole block of chocolate and in one fell swoop take in your whole day's worth of calories. Slider foods will not help you lose weight. To feel 'full' you need to be eating a low fat, balanced diet of foods that are not too processed, an probably not more than a cup or 2 of it at the most, or a small plate's worth. And then if your band is working, it will keep you 'full' for 2 - 3 hours thereafter. If you can't eat fish or chicken or anything but soups, you need to talk to your dr, not just eating slider foods.
I would suggest food journalling but I think it actually goes further back than that. You need to learn to eat right and work WITH your band, because right now you're working against it by the sounds of it.
Feel free to PM me if I'm out of line, but just from your OP, I got the impression you either don't understand how your band has changed the way you should eat, or you just don't know what you should be doing.
