OK on page 108 (chapter 6) of the CAD book it states:

Although there are no forbidden foods on the Carbohydrate Addict's Diet (subject only to any dietary restrictions your physician recommends), carbohydrate-rich foods should be eaten only during your one-hour reward mal. We're defining carbohydrate-rich foods as "those containing MORE THAN FOUR GRAMS of carbohydrates per average serving".

So there we have it. I knew I wasn't loosing it (well not that much anyways)

I figured I couldn't have just invented that number in my head.

So there we have it. The answer we've been looking for.
