any particular reason you chose 6 billion? (Just easier math?) While I thought the current estimates were closer to 7.1 billion. Though I doubt those 7+ billion people eat 2000 calories per day. When you consider how many people are starving in the world, I am not sure if its offset by the overeating overweight nations. tl;dr; why 6 billion?

I'd bet it's because the world population is a mesofact, and it's easy to forget that your information is out of date: http://www.boston.com/bostonglobe/ideas/articles/2010/02/28/warning_your_reality_is_out_of_date/ http://www.boston.com/bostonglobe/ideas/articles/2010/02/28/...

  The author talking about the Boiling Frog myth as a fact is quite ironic in this context.

    Well, when used as an analogy, it doesn't have to be correct. But still, you're right. While looking this up, I came across the craziest sentence in the Wikipedia article: "German physiologist Friedrich Goltz demonstrated that a frog that has had its brain removed will remain in slowly heated water, but an intact frog attempted to escape the water when it reached 25 °C." Apparently this isn't quite as crazy as it sounds, as the brainless frogs still exhibit some reflexes, to the extent that they'll jump out of hot water. But still, it reads like a study in "WTF did you expect to happen?!"

      >"WTF did you expect to happen?!" // Often we all assume something and so no one really investigates it properly. Science must concern itself with things we think we know are a priori truths in order to provide a solid basis for building on. That said Goltz experiment seems quite reasonable to me, ~"do frogs have non-brain based reflexes that react to temperature?", ~"do frogs react to absolute temperatures or just changes in temperature". https://archive.org/stream/studiesfrombiol00martgoog#page/n405/mode/2up https://archive.org/stream/studiesfrombiol00martgoog#page/n4... at p.389 suggests that the frog with "no cerebrum" is in some way alive in Goltz experiment - perhaps it is missing that point that makes you say WTF? It seems the excitability of headless frogs in varying temperatures was quite a point of interest, see eg p.393 ibid.

        It's just a knee-jerk reaction, "Duh, of course the frog with no brain doesn't jump." The difference between intuition and reality is the humor here.

I'd like to point out that how many calories they consume does not necessarily affect the number of calories they burn (excusing starvation mechanics since I have no idea how that works).
