One more thing. In my opinion looking at how we got here is important because if you believe in evolution and in how long it takes us to change then you have to wonder what got us here. What did we eat to survive (only the strongest survived).

If you go back before farming started and actually fire even plays a big role in changing us (long summer days ment eat more carbs, can get in summer, and fatten up for winter. It ment have sex, have kid in spring. Too little fat on a woman and she can't get pregnant-it would be a waste cause it wouldn't work)..

Anyway we followed the herds, not the the vegetables! :P

Seriously though. We were hunter gatherers.

Now without farming where would one get such large quantities of carbs?? Certain seasons more than others (you can eat more carbs in summer and stay up later) but in the winter months there sure as hell wasn't many carbs about...

The native Indians in N. America ate about 70-90% protein/fat and they WERE bloody healthy.

They could not get many grains (grains kill), vegetable, or fruit throughout a good portion of the year. Much of Europe is the same.

There are some areas were higher carbs were consumed but always with animal or animal products (not excluding sea food in animal).

How we got here was not being vegetarian or vegan thats for damn sure..

So if your ancestors are from a place with winters you might suspect (if you believe in evolution) that you have a genetic requirement for at least some MEAT!!!

IMO
