i know.im an ass but i cheated almost everyday of my preop diet i was starving instead of broth i was eating top raymond and i would addd.a full.can of beans to it. plud the first week i went out and ate salmon and fish alot with rice and potato salid and baked potato although i did stick to the two days of clear liquid before sugery, i am doing great already lost twenty pounds in to weeks and a ton of energy,and.to be honest i am also a smoker and i smoked a couple of ciggerettes the day before surgery,i am by no means advocating thease things but were humen n if u cant stick to it completely dont worry. i think.the preop diet is so u can get used to eating like that afterwards. n trust me when i say it wont be hard at all.to do that because im always full always and even when i get a little hungry a couple sips of protine shake n your full.again.
