i've done this with chocolate protein powder right before my cardio first thing in teh morning, its not bad at all either.
EDIT: I had wrote out a whole thing about why carbs are superior to protein before cardio, and they would be to support a person who's priority is cardio, but I suppose I should modify this for bodybuilders. this is my new equation:
empty stomach > protein
normally I would recommend carbs before cardio for better workout, in a nut shell you are low in glycogen when you wake up, so you want carbs to burn over protein because protein takes more energy, lowers testosterone, and increases insulin when converted to glucose in gluconeogenesis. this is why you shouldnt take protein before lifting, as you want those extra ATPs (and not the other negatives). studies prove that exercising on an empty stomach burn quite a bit more fat. I am unsure how this affects metabolism though, what are you teaching your body? exercising moderately and not fast burns more fat, and also trains your body to go for the fat quicker than glycogen. you would think this and going on an empty stomach would prove very beneficial, however I am unsure about metabolism increase, as you burn the most fat at rest, so it is most beneficial to raise metabolism when doing cardio. for this reason it might be better to train faster.
I am going to continue searching for studies on muscle loss with cardio, if its possible to measure that, and try to tie all these things together.
if you know what youre talking about please try and help me out here
