FYI
The 1gram/ 2 tbsp of carb is from the natural lactose. Whipping cream (unless you mean the commercial stuff in a can) in it self does not have added sugar. Cool whip on the other hand is an edible oil product and has a lot of added chemicals and sugar.

I personally love and use a lot of heavy whipping cream, it's natural and adds lots of flavor. It is also on the can have list (in moderation of course) for Atkins. There are some things you got to just love about this WOE.

hope this helps
