without the gall bladder you can't concentrate the bile, (which breaks down the fats) but you still make it in the liver. Some people will not be able to take higher fat foods, and atkins is higher in fat than many diets. BUt if you are not having problems with fatty foods, you should be fine.
If you have some problems with the fat content, you can go higher up on the carb ladder and reduce the fat a bit.
good luck, let us know how things are.
