I'm scheduled for bypass on Sept 7th....I start my 7 day pre-op diet Thursday. I was a little anxious about doing the liquid diet but my surgeon has a different plan. i will be having a protein shake for breakfast, one serving of fruit and a light Greek yogurt for mid morning snack, protein shake for lunch, a string cheese or hard boiled egg for mid afternoon snack, dinner is a lean cuisine or healthy choice frozen entree with a good source of protein (approx 300 cal) or 3oz of lean meat/fish and a serving of non starchy veg and an evening snack of a string cheese or hard boiled egg, and drink a minimum of 64oz of water. No liquid diet at all!
