mjsx3,
you might want to listen to what all the others have answered you.

LC "frankenfood" bars and shakes are infamous for causing problems. Too many people report stalls or slow-downs in their weightloss not to take that into consideration.

When Atkins turned into ADkin$ and started to produce and sell all these LC junkfoods, they lost a lot of respect in my eyes. I go by what the late Dr. Atkins originally said, not paying much attention to the ADkin$ sales depts reassurances on sugar alcohols...

There is an excellent article on sugar alcohols here:

My advice would be to try to stick to natural, unprocessed food, especially for Induction and you'll avoid disappointment later on. If you really want to have those LC bars, save them for occasional snacks for late OWL/pre-maintenance instead.

Best of luck with your new WOE.
