I buy one called protein Diet, its is by Optimum Nutrition, I get it at GNC, it has 3 carbs per serving. Atkins also has a protein shake. There are also recipes in the forum for different "make it your own" protein shake, Natruska drinks her own quite often, I just find it simpler to buy it and blend it up. They also have canned protein shakes, but I find the ones in the blender with a little ice is tastier.
