You might also want to think about products like Wasa Crispbread with Bran (thirty calories a piece), Orowheat's light whole wheat bread (40 calories a slice), and using multigrain products like Barilla Plus pasta.
I go heavy on greens like salad greens, spinach, brocolli, asparagus, some beans in small amounts, eat lean meats, fish, chicken, a bit of feta cheese, salmon, chicken, non-fat cheese slices, lots of Carb Control yogurt (one with every meal, and I also take calcium supplements), non-fat cottage cheese, berries, walnuts in measured amounts, some olives, sweet peppers, and other healthy things like that.
I try to drink a lot of water, but I forget sometimes. My goal is at least half a gallon a day.
I write down everything I eat, and if food makes me crave to eat, I avoid it during the day, only eating it at dinner time (for some reason, this works for me. I don't snack after dinner, unless I am up many hours later).
There should be no truly "forbidden" foods except for those you choose as healthier over less healthy choices. I don't eat a lot of fat because I don't digest it well. Too much carb gives me craves, but I am always struggling to get enough dietary fiber in. And enough fruit.
You have to work with your body, figure out what works with your health conditions, and take it from there. And be honest with what's going on and don't worry if you're not perfect, and you will do fine.
