The New Age Cavemen and the City
This was in the New York Times. Art DeVany, Erwan LeCorre, intermittent fasting and Crossfit also get a mention.
It might just be me, but I sort of feel that they are making fun of the approach a little bit. For example:
The caveman lifestyle, in Mr. Durant’s interpretation, involves eating large quantities of meat and then fasting between meals to approximate the lean times that his distant ancestors faced between hunts. Vegetables and fruit are fine, but he avoids foods like bread that were unavailable before the invention of agriculture. Mr. Durant believes the human body evolved for a hunter-gatherer lifestyle, and his goal is to wean himself off what he sees as many millenniums of bad habits.
Don't we all fast between meals?
It is all becoming too fashionable.
