Simply put, beware of "impact" carbs! Those Pria bars (and most "low carb" bars) contain sugar alcohols...mainly Maltitol...or as I like to refer to it as instant gastric distress!! The companies that make those bars arrive at the impact or net carb counts by subtracting fiber as well as sugar alcohols from the total carb count. Unfortunately, Atkins bars are no exception. My complaint with Atkins bars is, they claim 0 grams of sugar alcohols on the front label...yet, if you read the ingredients, they contain Glycerine...which IS a SUGAR ALCOHOL!
My best advice to you, stick with real, whole foods when doing low carb. Remember, regardless of whether or not something claims to be "low carb"...low carb junk is still junk just the same.

I'm not a low-carber, per se, but I am Diabetic and both the American and the Canadian Diabetic Associations recommend that the carbs shown for sugar alcohols be considered as having approximately 50% impact on blood sugar levels. In actual fact, different SAs have different carb levels, but 50% is close enough. Those labels that totally discount the SAs as well as the fibre are one of my pet peeves, too.
And here we go for 2009 . . . Onward and Downward . . .
