Not stupid! I had to learn it too! Frankenfood means man-made: Certainly your protein drink qualifies, but bread also might be called Frankenfood. The contrast to Frankenfood is whole food as it comes from the animal or the earth - veggies, fruits, meats, fish, milk, eggs - no processing other than cooking! The number of stall threads I have seen that ended up with that recommendation is dozens!

Other ideas: allowed fruits, whole grain cereal (like Bob's red) that is just ground grain, with milk or water. You could try adding cheese, yoghurt etc. - the dairy industry cites that dairy helps dieting and for me it certainly is good - and it seems with your other restrictions, and I believe some is also allowed with Atkins.

But just don't be impatient - stalls are normal, especially when you are within 10 lbs of where you want to be. Read the book again about the end phase! Good luck!
