Apart from all that strange and emotional animal food discussion (which
begun to saw my nerves), I am reminded to a different approach that came to
my mind. And it makes sense to me:

Eat as much plant food as possible.

I don't mean any plant, but in particular low density plants:
Vegetables, fruit, greens.

I really think that this is a promining and maybe basic principle of real
paleolithic ways of nutrition.
My ideas go a follows:

Nowadays, due to limited eating time and other demandings of convenience
it's a usual to eat food as *dense* as possible.

Now, think over how much of various kinds of food is necessary to sustain a
humans life. To achieve 2400 kcal and RDA of protein you need to eat
(over the thumb):
high density:
250g of (lean) meat plus 250g of fat
or 650g of cereal grains
or 350g of nuts

Low density:
or 2000g of tubers
or 4000g of vegetables
or 8000g of fruit.

That means: if you happen to live mainly on vegetables you eat quite
unbelievable amounts (8 lbs) of food which is full of healthy
micronutrients.In this way you get really very high amounts of all the
necessary micronutrients as well as fiber.
Add a little meat, fat or nuts and you can vary the total weight according
to your whishes.

I you do increase the low density side of food you gain the following
benefits:
1.you get vitamins, minerals and fiber in very high amounts
  - like nutrition teachers try to encourage us.
2.you can eat any quantity you want to - unlimited eating

Isn't that what most of us desire?

Poor people in poor countries eat only some dense basics.
Like for example only some rice with little else (they can't afford).
That works as the least cost nutrition (lacking only vitamin C and A to a
complete RDA nutrition as I've pointed out sometimes).

But if we can afford much vegetables and can enjoy the ready availability of
them in our society, we are free to increase this vitamin and filling food
ad libitum.

If I'm cooking or eating out I've changed my habits to eat really big
portions of vegetables. Often one pound per meal.
Only then I add some dense convenience food.

Like a half hokkaido (pumpkin) with half cup of quinoa and some tasty fat
(like coconut, olive, flax, hemp).

Of course some of the denser items can't be avoided - you need the protein
to avoid becomeing hungry after short time.

I found that to be very pleasing and satisfying for me.
And in nutrition program tests I often score high above the 100% marks for
most vitamins.
In this way I get an abundance of vitamins and if I take care to get enough
protein I can vary my *caloric* intake almost at will.
I don't eat intentionally low calorie, but I'm satisfied at
moderate caloric intakes despite my love for fats.

Thats: Eat as much plant food as possible.
