I've just started making a real effort in eating Primal, but I'm currently living with Auntie MD (my aunt, who is a doctor, and smokes 1+ pack a day) and she does make things a bit more difficult...
She's stuck on CW and insist that cutting carbs and grains is unhealthy, and that fat will make you fat.
Luckily we're in France so it is more a question of the French paradox (baguettes, cheese,etc.) than a low fat point of view.
I'll move out once things stabilize, but got now I just try not to eat anything "bad" and suck it up the rest of the time.
Once you learn that you create your own reality and that you are fully responsible for your life, you can begin to see the world as it is and then you realize the limitless possibilities.
