Dr. Illan has a nutritionist that saw me briefly in the hospital and gave me a bag of goodies (mostly clear liquids), and a printout of the post op meal plan.
The plan was very easy to understand, and had a page for each week (up to 8 or 9 weeks post). There is a list of approved foods for the week, as well as a sample daily plan, including target food weights.
I was concerned pre-op by the 1/4 cup, 1/2 cup, etc. This plan does it much better: 2oz cottage cheese, etc. I found it easy to follow, as much as I wanted to follow, or make it my own (sticking to the approved foods list, of course).
I kept that paper in my purse for the first 2 months, reviewing it several times a week.
