Query: Buyer beware: 12 grams of carbs, not 2 grams...

These balance bars use the sugar alcohol maltitol, which has 2.1 kcals/g (see wikipedia). The bars contain 20g of maltitol = 10g of sugar (sucrose has 4 kcals/g). When you add the remaining 3g of carbs minus 1g fiber, these bars have a total of 12 grams of carbs, not 2 grams, as the label claims. Not to mention, maltitol can cause bloating and/or diarrhea.
