Obviously none of us need a reminder that this is a terrible idea. But I thought this was a really thoughtful and well-written article. Apparently the controversial, alt-right psychologist Jordan Peterson and his daughter believe a diet of nothing but beef, salt and water is best for them. I've copied a few paragraphs below, but it's worth reading the whole thing. https://www.theatlantic.com/health/archive/2018/08/the-peterson-family-meat-cleanse/567613/ "The idea that alcohol, one of the most well-documented toxic substances, is among the few things that Peterson’s body will tolerate may be illuminating. It implies that when it comes to dieting, the inherent properties of the substances ingested can be less important than the eater’s conceptualizations of them—as either tolerable or intolerable, good or bad. What’s actually therapeutic may be the act of elimination itself. For centuries, ascetics have found enlightenment through acts of deprivation. As Levinovitz, who is an associate professor of religion at James Madison University, explained to me, the Daoist text the Zhuangzi describes “a spirit man” who lives in the mountains and rides dragons and subsists only on air and dew. “There’s an anti-authoritarian bent to pop-culture wisdom, and a part of that is dealing with food taboos, which are handed down by authorities,” Levinovitz said. “Those are government now, instead of religious. And because they are wrong so often—or, at least, apparently wrong—that’s a good place to go when carving out your own area of authority. If you just eat the ‘wrong’ foods and don’t die, that’s a ritual way to prove that you go against conventional wisdom.” Peterson’s narrative fits a classic archetype of an outsider who beat the game and healed thyself despite the odds and against the recommendations of the establishment. Her story is her truth, and it can’t be explained; you have to believe. And unlike the many studies that have been done to understand the diets of the longest-lived, healthiest people in history, or the randomized trials that are used to determine which health interventions are safe and effective for whom, her story is clear and dramatic. It’s right there in her photos; it has a face and a name to prove that no odds are too long for one determined person to overcome. ... The allure of a strict code for eating—a way to divide the world into good foods and bad foods, angels and demons—may be especially strong at a time when order feels in short supply. Indeed there is at least some benefit to be had from any and all dietary advice, or rules for life, so long as a person believes in them, and so long as they provide a code that allows a person to feel good for having stuck with it and a cohort of like-minded adherents. The challenge is to find a code that accords as best as possible with scientific evidence about what is good and bad, and with what is best for the world."
