My favorite shake is pour some diet orange soda, about 2 cups, 1 scoop vanillia whey protien, ice cubes and when I have some crushed pineapple, I throw that in. I know that we're not supposed to have soda but when you blend it up, it loses it's fizz. I've also tried diet cherry, strawberry, and just regular cola. Tastes sort of like a coke float!!
