Hello Jessc1984,
I just started my pre-op liquid diet as well. I believe all doctors are different, while my doctor did not enforce it as some have; I have started it because I want to make the most of the process. I was handed a guide line that included:
Breakfast: Protein liquid shake
Lunch: ½ cup of veggies (asparagus, zucchini, carrots, broccoli, try to stick to green veggies)
And side green salad w/ vinaigrette or lemon based dressing, NO oil based or Creamy dressing
And 8 oz of chicken or fish (grilled, broiled, HEALTHY)
Dinner: Protein liquid shake
LOTS OF WATER!
I do want a snack, but I think it is more physiological
