Hi! I personally like to buy just plain protein powder in bulk... if you live in california or have an Albertson's or Raley's around, i've found both of those everyday supermarkets have plain protein powder, and it contains 0 carbs, I put 2 heaping tablespoons of it in a blender with 8oz of water and a few tabelspoons of atkins flavored syrup, and presto... a 0 carb shake... very good too I might add! (only 40 cals too, and 0 fat!)
