Frankly, I think the South Beach and, especially, the Atkins diet are really just gimmicks. For most people, to lose weight it's about burning more calories than you are taking in. However, i do think Diabetics hve to be more conscious of carbohydrates since it gets metabolized into glucose more readily than protein or fat. And for those of us on insulin, the more carb we eat, the more insulin we need, etc. And insulin isn't exactly an aid in weight loss.
I would try to eat everything in moderation. Cutting out any food group seems a little too drastic to me. A food group is a food group for a reason
