Come on. Use your head here. I'm not trying to be rude but look at the ingredients like I said to do already and you'd have the answer.
I doubt fermented fiber is what they are counting toward the carb count. Nearly all the ingredients are actually quite high carb ingredients (even if they are sprouted).
Kamut is the first ingredient in this "special bread." As an example, here's another sprouted kamut bread showing 17 net carbs per slice: http://www.thedailyplate.com/nutrition-calories/food/nutriforce/sprouted-kamut-bread
Is it so hard to think that the bakery made a mistake on the label by not listing the carbs as "impact carbs," and or is lying to deceive people too trusting/ignorant to know any better? This case is pretty much a perfect example of how the blind lead the blind with regard to nutrition in this country. There are people in this thread pointing out obvious flaws and the answer is still hidden somehow.
I just read over the ingredients again, and this product has wheat and wheat gluten in it anyways... this is no better than 8 grain, high fiber, or high protein (your choice) bread from the grocery store. All the varieties of bread I just mentioned are crap from a nutrition standpoint, IMO. At least this stuff is sprouted, but still...
