Preoperative Ketogenic Diet for Reduction of Hepatic Steatosis

Non-alcoholic fatty liver disease is becoming increasingly common in Canada and throughout the world. Fatty liver can increase the risks of perioperative complications for those who need liver surgery. A ketogenic diet is low in carbohydrates and can be very effective in reducing liver fat content. The purpose of this randomized control trial is to compare the effect of a short duration (4 week) preoperative ketogenic diet on operative and disease outcomes in patients undergoing liver surgery. One arm will be randomized to the ketogenic diet and the other will receive standard of care pre-operative dietary consultation.
