LAST YEAR, I DECIDED
wanted to learn how to eat healthier. (Surprise! We’re not all macro-tracking body-builders over here at ) So I searched—Google, TikTok, Instagram, YouTube. And my research all seemed to lead me to the same kind of advice: one-size-fits-all directives, delivered by confident and attractive social-media stars and online influencers, all hawking video courses, e-books, YouTube channels, podcasts, and specially formulated vitamins. Their collective pitch: They alone hold the secret knowledge that will propel me to achieve my goals—for a price, but hey, it works for hundreds of thousands of their followers. And there of these advice givers.
