P90X, Insanity, or a hybrid schedule of both workout programs?

You know that's not always the best advice.
Bodybuilding.com - High-Protein Diets: Are You Losing More Than Weight?
Too much protein can harm your body - on MedicineNet.com
I think we can all find enough protein in our diets to reach reasonable levels, they recommend about 0.37g per pound of body weight. I'd take 1g as an absolute highest amount, really for serious bodybuilders, not average people

Came in here to post this. It's .8g of protein per 1kg of body weight. For the sake of simplicity, you can say 1 kg = 2lb. So .4g of protein per pound. Most of the advice on nutrition and weightlifting you see on magazines and on the internet is made by steroid users for steroid users.

There is no real secret to the nutrition:
Eat lean meats (fish, poultry).
Eat lots of fruits and vegetables (orange and green leafy vegetables).
Eat low fat foods (especially low saturated fats).
Mono unsaturated fats (usually found in nuts) are good for you.
Limit the amount of refined carbs you eat (pasta, bread, sugar).

As far as this GOMAD thing, a quick search on the internet makes me pretty skeptical. For instance:

Is GOMAD Safe? Yes. Or we wouldn't feed babies milk.

You don't feed babies a gallon of milk per day. Just because a few glasses of milk per day is safe doesn't mean that a gallon of whole milk per day is safe. Claims like this make it obvious there's no real science behind this and just a fad. Not to mention the high incidence of lactose intolerance among non-western/Mediterranean non-white people.
