Protein drinks? I can't drink them??

Protein shakes are great before or after. I'd have to agree the Lean Cuisine are not. Too high in carbs, too low in protein. Atkins meals aren't bad if you have to have that convenience. But meat, eggs, and veggies are good choices. If your preop is intended to shrink your liver then carbs aren't your friend. My doctor would tell you no sugar or flour based foods and nothing over 10-15 grams carb in one meal.
