hi-
there are no bars or shakes allowed on this plan, according to the Hellers. I think lots of people on Atkins got into difficulties eating these things, but this is a YMMV issue. Dr Eades now has a book out where he recommends a protein shake.

I don't eat bars or shakes, but I do have an emergency snack- I take it on vacations and flights and hikes. It is an ostrich meat stick- I think Ostrim- that netrition sells by the 10 pack. It has no sugar or carbs in the original flavor- and tastes like a slim jim to me. It is 80 calories- I think. You can look at other meat bars and meat jerky things. Just be careful about the sugars! I found one beef jerky that was not sugar treated, but it was a lot more expensive than the sticks.

HTH
