I know there are some guys who eat only whole foods.
I guess it depends on how your appetite is.
Me personally wouldn't even be able to come close to the amount of cals and protein that I need w/out shakes.
I've been drinking mostly shakes this cycle beside 1lb. steak and some milk due to some stressfull personal issues, but I have to say that I can't tell a differance.
As long as you're getting in the cals and protein, to me that's all that matters.
