The Liver Shrinking Diet (also know as LSD) is a high protein / low carb diet that helps to prepare your liver to stand up to surgery. In obese people, the liver tends to be fatty and can bleed easily. By removing as much fat as possible, this increases its safety in surgery. Patients with a very high BMI may be asked to go on this temporary diet. Dr. Kuri and your Facilitator will let you know if this is something you will have to do pre-surgery.
