I had to do a 2wk pre op diet as well. First week was 2 protien shakes not to exceed 200 cal a piece and a meal at upper. 3 Oz of lean meat and a 1/2 cup of veggies. Atkins meals were the best. They wanted me to take in 90 grams of protien with less than 15 carbs a day. The second week was just protien shakes 4 times a day. I started the diet weighing 373 and the day of my surg I weighed 346.
