The percentage of carbs that Fitday shows is net of the fiber. For example today my numbers were: 41 carbs less 17 fiber = 24 net carbs times 4 cal per carb = 96 cal divided by 1578 total calories = 6% calories from net carbs.

For the LC bars that have maltitol, I enter the fat, protein and NET carbs per the label and plug the difference into alchohol to make the calories tie to the total per the label.
