@therjes ...Back about 8 years ago I had my gallbladder removed for the same "stone" reason.. I am quite slender and eat what one would call a low fat diet.. ...I eat very little red meat.. After surgery I just kept eating as I had ... and I had no problems.. except kidney stones a few years later (those were causes by too much rhubarb and spinach (oxalates).. If you measure things very carefully, it should be easy to compare how a recommended diet compares to your regular diet... Good luck..
