The Carbs and Cals book suggesed by Sam is excellent. I've had mine about 18 months now. It's particularly good on portion sizes, with photos of the foods in plates of known diameter. My husband, who has kidney failure was recommended it by the renal unit dietician, who was surprised to find we already have a copy. Portion and plate sizes are very much an issue. On our recent cruise and on the previous one, we had a "fine dining" dinner each night of 3 to 5 courses. It proved to be no problem for bg control as the portions were small at each course. I even had a SMALL piece of Baked Alaska without doing any damage.
If I didn't already have too much crockery, I'd buy myself plates and bowls to match those in the carbs and cals book.

PS I walked up 10 storeys worth of stairs after dinner each night too.
