And exercise, for that matter. Some people are going to do better with different balances of macronutrients, but that's far more particular and individual than blood type.
Your family may not have the good sense to listen to you, but that's their problem. All of these various food fads are just ways for folks to try to sell books, because they know that the message of eating a balanced, whole-foods diet is not sexy. And everyone is looking for some way around taking responsibility for what they put into their mouths and how little they move. But long-term, it's the only thing that works. We know there's no magic out there, but that's not a message most folks want to hear (particularly here in America). <sigh>
