I personally like Atkin's "new and improved" bars. But they made me stall on induction. I'm redoing induction as a result. So, I'd say wait until after induction before having the bars. During my second week of induction I would have one bar a day (and I did not lose any weight and was out of ketosis; after my first week, without any bars I lost 6lbs). Maybe if I had only a bite of a bar a day it wouldn't have stalled me. But after reading posts on this subject, i've decided to hold off until after induction.

Good luck!
