they will throw you right out of ketosis. I read in the new Atkins Handbvook that comes with the Trial Kit that you should limit yourself to one Atkins Bar or Shake per day while on induction. I would say - you ought to even be more stringent with the chocolate bars with high sugar alcohols. Yes, they may say that they have no or low net carbs, but actually take a look at the ingredients list and see what you're eating.

I decided I didn't need chocolate THAT bad.

Good luck.
