Actually, whey protein is the principal ingredient in "protein drinks" that are one of the very popular "diet foods" recommended by weight loss clinics for their more affluent patrons. Poor people can't afford the clinics, and certainly couldn't even consider paying the outrageous prices demanded for some of the "special diets" they push, but they're very popular with the (fat?) moneyed crowd, and are considered "desirable supplements" for the body builders down at the gym.
