Hi PANDORA . . . wave: . . . I see you've already been directed to a couple of places that might be right up you alley . . . I'm the Mod in both the Age 50+ forum and the Diabetes Forum and we'd love to see you in both or either of those places.
You are definitely on the right track with portion control and exercise but be sure to keep your carb intake spread as evenly as you can over the day as well.
If you want to take a look at a couple of plans that are pretty good for controlling blood sugar take a look at Sugar Busters and the later phases of South Beach . . . both have their own forums . . . I tend to think of them as 'controlled, or good carb, plans.
Hope to see you around . . . keep things moving and shaking, Chickie.
