I would dearly love to take time to develop this tonight, but I'm fixing dinner for friends (2nd night in a row, with Thursday for family coming up).
Here's the refresher course. Gary Taubes' "alternate hypothesis of fat accumulation," (in my crude way of explaining it). Simply stated: people overeat because they are (have accumulated excess) fat, and it's not that they are fat because they overeat (cause & effect reversal; 180 degree error; the easiest kind).
Here's a quote, and I'm quite certain the author will be fine with non-attribution for now, 'cause if Ilinked it, too many of you smart ones would figure it out (those who haven't already).
Applying the 1st Law [of thermodynamics] to living organisms is Proof by Tautology. Yes, 1 + 1 = 2, but this tells us absolutely nothing about the underlying mechanics. The 1st Law does not (I repeat N-O-T) tell us whether you store excess energy in the form of fat, or bleed it off into the atmosphere by dilating blood vessels next to the skin, sweating, etc. To do so would require an accounting of entropy.
I read that twice the other day, as part of a long piece (which I have linked, BTW). But only today did it jump out, off the page, and bite me like a snake. Finally, I thoroughly understand Taubes' alternate hypothesis for fat accumulation.
Here's a chance for you to think about it, in the context of the "energy is neither crated or destroyed, calories in, calories out" failure.
Let me emphasize. There are still thousands upon thousands out there vigorously trying to shore up their bankrupt hypothesis. See if you can understand more than they do by tomorrow. Clue: trying to apply 1LT to a human organism exposes supreme ignorance. It is in their ignorance that they fail.
Observe America over the last 20 years. It is the 1LT-based hypothesis fully applied to practice.
