Wow, sounds like most of you have been allowed to have a lot more than my surgeon allows. I just started my pre-op diet yesterday and all I can have is 2 protein shakes a day, 1 cup of broth based soup or 1 cup of low fat cottage cheese, and one snack (all non-fat, sugar free) of either pudding, yogurt, or jello. Other than that all I'm allowed to have is decaf coffee or tea, sugar free drinks, sugar subsitute, non fat creamer. I'm starving and have noticed my mood has become a lot more angry and short tempered. I've been trying to supplement with fiber pills to help me with the hunger, but it's not helping much. I'll be on this diet for 2 weeks, surgery on 11-11-11. My surgeons office told me the purpose of the pre-op diet is to shrink the liver in order to have better access during surgery to place the band. Surely I will loose some weight as a result of the pre-op diet as I'm starving myself.
