I used to buy sliced peproni too untill I started eating a whole package a day so ya I know what you're talking about on fitday..lol

It has 0 carbs if you eat it by the serving size, or .99 carbs or something..fitday will just count it anyways. Are you checking the serving sizes? Cause like the package might say 10 pieces, 0 carbs..fitday will say 1 cup= 2 carbs... which both would be right...

Solution?

Easy. Just customize everything you eat regulary into Fitday. Because even if the serving size is 1 cup and you eat 1/2 or 3 cups.. Fitday will automatically figure out the correct carb count based on what you entered for the customized label.
