There is a page that mentions less than 4 grams and I think it is in with the list of cheeses possibly. I also think it might be in the CALP book but I can't look it up because I don't own that one.

You do not have to count carbs, calories or anything else besides that though.

I know for myself, that sometimes I use the WASA crackers for one of my craving reducing meals with chicken salad on them. They are 7 grams.. so I cheat according to the 4 gram rule, but they don't cause cravings for me either, so it's a nice treat to have every once in a while.
