I am in MA. I am having mine done at Brigham and Womens. I have a two week pre-diet.
Pre-Operative Diet
The preoperative diet is required for all patients before weight loss surgery. This diet will help to make your liver smaller which makes it safer and easier for your surgeon to perform surgery.
Start this diet 2 weeks before your surgery date.
Every day during the pre-op diet, you will do these 2 things:
Follow the instructions in each box. For boxes A, B, C, and D, choose 1 item to eat or drink during the day. For Box E, consume 1 meal.
Drink at least 64 ounces of sugar-free beverages (water, Crystal Light, Fruit2O, etc.).
With 1 item from each box, you will have 5 eating events per day.
