I know that Atkins labels his products with both carbs and net carbs. Net carbs are those after fiber is subtracted.

WW has done this also. I was on WW123 and they subtracted fiber and I believe on the new plan they do also for the point value. However, I think it was hotly debated in WW as to whether or not you really "should" deduct the fiber and I think there is some difference between 123 and Winning Points in how it's calculated.
