The bars contain sugar alcohols, like glycerol or maltitol etc. These show up as carbohydrate on the labels. Some people don't count them, some people count them, some people compromise and count 1 gram of sugar alcohol as 1/2 grams of carbohydrate. I don't eat them, but if I did, I'd probably count them as half a gram per gram. Which is pretty much why I don't eat them, even at that, they'd pretty much knock the veggies right out of my diet.
