  I don't think so. Only 10-20% of the energy we get from food can be used for manual labour, and that's neglecting rest and sleeping periods. If what GP is saying wasn't true, hunter populations wouldn't be able to survive. This is also why reduced calorie intake is much more effective than increased activity if you want to lose weight.

  I think the fatal flaw in the argument here is that the hunted animals are seen as a magic free resource; in reality of course they're a limited resource taking up valuable land, and we could never sustain 7bn people or anything like it in this way.

    How's that a "flaw", I wasn't advocating one thing or another. Of course 7.4 billion and growing cannot feasibly all enjoy the bountyful abundance of game and leisurely pace of our pre-neolithic ancestors (or North-American natives etc) =) It's still a plus to acquire just another added perspective on fuel yields for different types of human societies and lifestyles
