Had my gallbladder out when I was 30 (10 years ago) by the less invasive laparoscopic surgery and have never had a problem since. I never developed the post-surgical diarrhea and high amounts (60-70% of my calories from fat) do not bother me in the least. Not everyone will have problems with higher amounts of fat following gallbladder removal, but some will; we are all unique and react in our own individual way to the loss of the gallbladder. If higher amounts of fat seem to bother you, reduce it gradually until you feel better, but no farther than that our you can cause yourself a new set of problems. Balance is the key. BTW...the pancreas produces insulin, the liver produces bile.
