My husband and I had to first lose 10% of our body weight before we QUALIFIED for the surgery through the facility we went through. Now I am on day 3 of a liquid diet (2 days creamy, 1 clear) and tomorrow is surgery. The NUT did give us a diet that was high in protein to lose the initial weight. Mostly chicken, pork, beef and 2 cups of veggies a meal. Shake for breakfast. And it worked fairly well and we were full. If you are interested I can give more specifics. But I dont want to interfere in your particular Dr.s goals for you. Good Luck!
