the secret to a healthy diet ! you have to earn every calorie you eat.!

1. In 1985  Boyd Eaton and MELVIN KONNER wrote a paper titled “Paleolithic Nutrition: A Consideration of Its Nature and Current Implications,” which appeared in The New England Journal of Medicine.
2. Our ancestors ate meat, fish and plant foods from the wild, but in what proportions? compiled data from 20th-century studies of what recent hunter-gatherers ate and tried to come up with a composite picture.
3. Whatever the ratio, our theory was that early humans who made it past the gauntlet of childhood microbes—which led to very high infant mortality and low life expectancy on average—would be much less likely to suffer the plagues of modern life: diabetes, heart disease, stroke, cancer.
4. Anthropologists estimated that their diet was 70% plant foods—a surprise to those who thought of ancestral humans as hunters first.
5. One fascinating new finding is that within the last few thousand years Eskimos evolved genes for enzymes to process the fatty acids in Arctic fish. ( go eat that blubber  you  stupid Atkins  and  VEERmachaneni Ramakrishna )
6. Our ancestors ate meat, fish and plant foods from the wild, but in what proportions? 
7. How do we know that we haven’t adapted to the average American diet? Because Twinkies and sodas have been around too short a time for evolution to deal with them.
8. In a 2014 paper in the Journal of Human Evolution, Amanda Henry and her colleagues found that even our Neanderthal cousins ate barley broth along with their steaks.
9. We reasoned that if other animals have certain diets that are natural to them—pet lovers will recognize this idea—then humans might, too.
10. Once thought of as extreme carnivores, Neanderthals were actually diet opportunists, just like our own direct ancestors.
11. We’d be wise to limit salt and saturated fat, which our ancestors’ prey had little of, and fiber and omega-three fatty acids seem to be good.
12. Our ancestors’ watchword was to eat while you can, the more calories the better—which didn’t do much harm when you had to earn every calorie and the spectrum of foods was healthier.
13. We still think that a mismatch between the lifestyle to which our genes are adapted and current habits helps to explain these new epidemics.
14. the “paleo diet” faddists urge their disciples to keep all carbs to a palm-size mound a day.
15. In 1985 scientists believed that few genetic changes had occurred since we were all hunting and gathering, say 10,000 years ago.
16. All of these strategies—low-carb paleo diets, too—seem to be compatible with life and health.
17. Anthropologists know that people obsess about diet.
