You need to look at net carbs, versus all carbs. The Atkins Advantage Bars have around 21g of total carbs, but the net carbs are only 2g (theses are the ones you count). After subtracting fiber, sugar alchols, etc.. they affect your blood sugar as 2g of net carbs. True some people have stalls when using these products, but I and many others have not. So you would have to try them for yourself to see how they affect you. One a day is plenty, don't go overboard with them or they very well may stall you. I really like the chocolate peanut butter ones. Hope this helps. Good luck.
