James Hamblin, writing for the Atlantic:
Even as someone who was seriously skeptical of Perlmutter’s story, after reading his 336 pages—and watching his whole YouTube channel and most every TV appearance—I have found myself hesitating around grain. His message is so ardently and unwaveringly delivered. That is how one-sided pop-science works. Katz wrote a tongue-in-cheek case that the 1974 advent of the Post-it note was the cause of the obesity pandemic, to show how easily correlations can be spun. If I read 336 pages on the evils of Post-its, I might set our office supply room on fire.
An interesting look at the latest fad diet.
