Never understood the "eat real food" argument. Talk about bro science bullshit. No one is saying only drink whey protein shakes. No one is saying whey protein shakes are superior. However they make a good quick ultra easy to prepare quick protein and or carb meal if you add carbs in if you are in a hurry to supplement your "real food."
People seem to think your body sits there, looks at the whey and says, I can't use this shit because it isn't real food. Your body will process the protein, carbs, and fat in it just like any of the real food you eat.
