[quote name='MaxBiaggi3']The overabundance and easy access to high calorie food today also greatly outpaces its available in past history.
No, this points to the fact that people have much greater access to cheap, government-subsidized, high-calorie processed foods today than ever before in history. You're suggesting that within the past 30 years as much as 1/3 of the U.S. population just suddenly and unexpectedly became addicted to overeating?[/QUOTE]
I agree with you.
A fattie can't put down the "chocolate covered ding dong" food product - it's an symptom of a food toxic society, combined with a culture of weak wills and increasing PC pressure to accept people who are indulging in gorging and gluttony (even proud of such behavior - I can't explain that one).
[quote name='MaxBiaggi3']You missed my point entirely. I'm suggesting that there were few (if any) fat people in ancient times. The people who were genetically superior (could store calories more efficiently) had the extra stored energy available/necessary to outrun those who were merely thin at the time. One needn't outrun the lion, just the slower frail thin people of the time.
If you were one of the merely thin in ancient times, you would probably have been dead.

You're never going to outrun the lion if you're fat - you're going to have to stop, catch your breath, and get picked off like the weak juicy target that you are.
If you follow track at all, you'll know that the best sprinters are huge muscular people with powerful legs and very little stored fat. Even the best long distance runners in the world are kenyans who live in the mountains and are so skinny they look like stick people (not the kind that has multiple fat stores).
Taking it back to evolution - look at the American Indians who have those thrifty genes. In tribal settings these people are lean and mean, but in urban settings they quickly get fat eating corn dogs, fried twinkies and other horrors of American mid-west cuisine. The fact is that in a more natural setting, where they ate food such as raw corn and squash, these people had a normal weight. However in modern times their newfound obeisity causes health problems such as diabetes, weakened immune systems and low tolerance for physical exertion - attributes that would have meant death "hundreds, thousands of years ago".
