A lot of Low GI recipies are low (or healthy Carb).. and so are most diabetic recipies... See GD is good for something.

Check out the Low Gi thread (sorry to naff to do linky things) and you might find some more ideas.

Prior to pg I lost over 60kg following a low GI / healthy eating plan and exercise... it really does work, includes food the whole family can eat, you don't feel hungry and its healthy.
