Hi JoyceGlasgow...
I don't have gallbladder either and I do follow a very low carb diet and have done successfully in the past always without a gallbladder. It is possible, low carb doesn't mean high fat, it just simply means you don't worry too much about the fat.
I love bread too but I find it really hard to just eat a single slice therefore completely getting rid of it makes my life easier. It is just much easier to deal with carbs cravings when you simply don't suffer them any more. As soon as I start eating them again regularly, my cravings for them increases... and becomes a vicious circle.
