Meh, I dunno. It doesn’t feel very convincing to me to rely on a disordered state as evidence for how to achieve similar results but in a disordered state.
I don’t think anyone, including the author, is saying that if you cut calories to ZERO you wouldn’t lose weight. Of course you would with NO intake. I think what’s being argued is that you can’t merely TITRATE one’s intake and expect a loss. Did you miss the part about how the body’s metabolism can titrate up or down by about 40%? Or perhaps you are suggesting a decrease in intake by 60% or 70%? Because the common decreases of a moderate, say 20%, seem insufficient and a decrease of what’s required, say 50%, seem wholly unsustainable.
Humans can suffer and adapt exceedingly well at the extremes. That’s one of our hallmark attributes in the animal world after all. But unless you are suggesting our obese friends start living in the extremes (“here, Mom, use this stick to purge or you get NO more food for 3 days!”), I don’t think you should be trying to draw such parallels because they simply don’t exist.
Ever hear of epigenetics? If so, lightbulb. If not, go read.
Our body responds in a million ways to environmental factors. Comparing prison camps to America 2017 is totally missing the mark.
