Gallbladder diet changes

Hey Yall,

I just recently found out I have Cholecystitis, within the next week I am scheduled to have a cholecystectomy. I have been trying to find information on the appropriate diet changes that I need to do before and after my procedure. My biggest issue is that their is a lot information out there but I can’t find any sources or studies to give me factual and evidence based information. Other than the recovery process I am also interested how the diet change will affect my powerlifting, where exactly should I go from here? Any information would be greatly appreciated.
