This protein talk is BS, unless you're an elite athlete there's no way you are not meeting your protein intake with a normal diet. Whatever excess protein you take will be converted to energy (or fat), so you're just paying more per Kcal than carbs.

Did you ever see prisoners? They get huge and they don't drink whey in prison, they don't even eat a lot of meat. All they do is rest all day and, in the limited time they have to workout, they pull heavy weights.
