Some patients will be prescribed a pre-operative diet to help shrink the liver.  Any patient with a BMI greater than 50 or a history of “fatty liver”  will be required to be on the following diet for two weeks.  Shrinking the size of your liver causes the operation to be safer.  If your liver is found to have too much fat in it, we will reschedule your surgery until the fat content is reduced by applying this diet program.

Lap-band pre-surgical diet instructions

Drink 4 servings of an approved protein shake each day each day.  Where milk is well-tolerated (soy or lactose-free milk may be substituted) it is recommended that two protein shakes servings are mixed with milk, the other two with non-milk beverages as shown in Mixing Ideas below.

  • Include at least 6 servings each day from the food list below.
  • Drink water or sugar-free beverages as needed during the day.
  • Add an additional serving from the food list for each protein shake serving when milk is not used as in the meal plan example below.
  • Consult your dietitian or physician for fiber recommendations.

*Digestive problems including gas, bloating and diarrhea may be due to lactose intolerance.
