I would also check with your doctor and see what he/she says. I know that my sister has had a lot of problems since hers was removed and she doesn't digest food properly. Especially anything with a lot of fat, she gets terrible cramps and everything shoots right through her. She lost about 20lbs since her surgery. There is no way she could do this diet, if you haven't fallen into the 10% with similar complications you should be alright. I think hers has something to do with stomache bile but I really do not know, there is some info online. Good luck!
