Personally I use the Atkins Advantage bars...they have more fiber which keeps me regular. I sometimes use them as an afternoon treat and crank the carbs in my totals at what they say are the net carbs. But I have only ONE in a day when I do have one... I don't think I could stomach living off of them. My daughter and I had a "discussion" the other day because she has been using the morning start bars for breakfast practically every morning whilst we're doing this WOE and I argued she has to vary her breakfast foods since she's hit a stall already.
