Being a bread person I had either slice of toast or an English muffin with little butter and 1/2 banana. Lunch some sliced baked chicken (small amount) with half piece of bread and dinner was jello. Does not hurt to be a little hungry and makes the process go smoother. I also cut my eating back a day or two before the procedure. I also started the prep 2 hours before I was told to. I like to be prepared for anything .
