I love these shakes and I drink them every morning after running. There called Advant Edge from the EAS company. They have Very little fat and Carbs but have a ton of protien and vitamen/minerals. I definately suggest these. If you cant find them, anything from EAS or MYOPLEX will problaby work.
Make you own...just start with skim or low fat milk, protein powder, an optional egg and flavor it from there.
I like unsweetened cocoa, artificial sweetner, xanthan gum to thicken and blend with ice cubes.
REALLY DELICIOUS!
