What's the story on these bars? It says 2g on the front of the label, but when you look at the back and subtract the fiber from the carbs, it varies between 10 and more. I have been doing Atkins for 4 weeks and only lost 5 lbs during induction, and nothing since. I recently started having one of these pretty much on a daily basis and I am wondering if the bars are causing me to stop losing.
