Plain yogurt is the way to go – avoid any varieties that contain flavor, color, even fruit. You want to add your own. I’ve done fruit (blueberries) and it is pretty good. I tried walnuts this morning to add a bit of flavor and juice up the protein. Never having done this before, I started with 0.25 cups (~ 2oz) of walnuts. That was way too many nuts. I could easily have gotten by with 1 oz or less. Having a better feel for the amount, not really sure about the taste. I will try again with the lower amount and vary with almonds.
Recommendation Today: Stick with yogurt and fruit.
