According to the Atkins website they are OK for all Phases.
I second Pandora on the real foods. I TRY not to eat anything not natural. I just started eating the Mock Danish with Cinnamon instead of 50/50 jams and such.
I also make a hot cereal close to Malt o meal.
Using hot water, cinnamon , salt and a pkt of Splenda.
heat the water and add the ingredients and let is sit 2 minutes.
Keeps you regular too!
