Jesus and Moses Went on Cleanses

That doesn't mean you should

Jasper Juinen/Getty Images News

One afternoon last month, I made a nervous visit to the office of Ghiora Aharoni, an Israeli sculptor and architect of some renown. The awkward part was that I hadn’t come to interview him about his work. I was there to hear about his gut. He had just finished a 21-day cleanse, the kind with supplements, protein shakes, and endorsements by the likes of Gwyneth Paltrow. (It’s called the Clean Program.)1 I’d been sent to Aharoni, who turned out to be extremely gracious, by a mutual friend, Ruby Namdar, an Israeli novelist whose skeptical intelligence and Falstaffian appetites made him the last person I expected to find on a celebrity diet. Indeed, the day I learned he was on it—over a dinner of baby carrots—Ruby was very hungry and very grumpy and at a loss to explain why he was doing this to himself, other than that Aharoni had talked Ruby into joining him and three other friends in the enterprise.

I wondered, too. What draws sophisticated and healthy people like Aharoni’s friends to commercial quasi-fasts? Cleanses, whether they last a day, a weekend, or three weeks, and whether they consist exclusively of fruit and vegetable juices or just a severe restriction of solids, are quickly becoming a part of what you might call the cosmopolitan diet, consumed in the more urbane sectors of New York and Los Angeles and Austin or wherever you find Whole Foods–levels of gastronomic consciousness and sufficient disposable income. (A three-week supply of Clean Program products costs $425.) Ask around, and you’ll probably find you know someone who knows someone who’s done a cleanse of one kind or another: Blueprint, Life Juice, Master Cleanse,2 Organic Avenue.

Ask a doctor about cleanses, though, and she’ll probably become enraged. I e-mailed Michael Gershon, a professor of pathology and cell biology at Columbia University’s medical school and the author of a groundbreaking work on the neurology of the gut called The Second Brain, and he wrote back: “I think that people who use cleanses may have had rough anal periods (see Freud, Sigmund).” Cleanses and their cousins, colonics, have about as much medical merit, declared Gershon, as the acts of penance done by monks who’d “walk across Europe and hit themselves on the back to purge themselves of the plague.”

The Clean Program is an ordeal. Its creator, Uruguayan cardiologist Alejandro Junger, told me that his customers undertake it to lose weight, prevent the inflammation that leads to chronic disease, and feel better. I asked Marion Nestle, the nutrition professor at New York University, whether a person would shed pounds on this diet. She had me read her the calorie count on the shake packets (150 each), then said, “It would be hard not to lose weight if you could stick to it. It sounds very depriving.” (Three weeks, she added, would be about the limit for that steep a reduction in caloric intake.) As for whether cleanses forestall illness, other doctors I talked to explained that that’s at best unproven.

But none of this matters, really, because people don’t afflict themselves for their health, or not only for that. I won’t be the first to point out that cleanses look a lot like religious fasts or that people crave the transcendence that comes from self-deprivation. “If you look at the history of humanity,” as Junger put it, “every spiritual giant or teacher or enlightened being has included some sort of fasting” as a form of discipline. Moses fasted for 40 days on Mount Sinai while writing down the Torah; Jesus fasted for 40 days in the desert; Muhammad also retreated to the desert to fast and received his first revelations from the Angel Jibril while fasting during Ramadan. “They didn’t call it detox at that time,” Junger added.3

Aharoni and others made it clear that they fast for more than the mere improvement of their psycho-physiological wellbeing. Aharoni described his cleanses as “journeys” or “traveling while staying at home,” phrases that echoed (to me, at least) the visionary transports achieved by fourth-century Christian desert ascetics and medieval holy women. As it happens, these saints starved themselves only partly out of piety; rejecting food, they also rejected a church committed more to institutional growth than the extremes of religious experience. Another explanation I heard was that people cleanse out of a sense of shame: Their eating and sometimes their lives feel out of control. In the past, this same feeling might have provoked atonement, particularly for the deadly sins of greed and gluttony.

These new cleanses are “religion without theology,” my friend Ruby quipped.4 But now that I’ve read Junger’s Clean, the best-selling text of the cleansing movement, I’ve decided I don’t agree. Clean is theology all the way down. As in many a devotional text, fasting is presented as a way to embody a purer social order.

We live in an age of what William James called “medical materialism,” so instead of fretting about a fallen world, we speak of a poisoned one. In a modern version of original sin, the corruption of our environment is so thorough that it defies individual efforts to transcend it: “Even those making good lifestyle choices still shower with city water, eat meals at restaurants, and live, work, and shop in buildings that have been cleaned and fumigated with toxic chemicals,” writes Junger. We might add to his list other features of daily life that we suspect may be dangerous but haven’t been banned by the authorities: cell-phone signals that may lead to brain cancer, endocrine disruptors that drive our hormones crazy, probably leading, again, to cancer. Distrustful of our surroundings, we try to close ourselves off to malign influences and to purge them. It is no accident that Clean dwells obsessively on defecation and elimination. Junger wants us to flush out shit, “toxic waste,” even mucus, which he says has “a dense and sticky quality; it resonates with and attracts dense, toxic thoughts and emotions.”

By interpreting cleanses more as symptom than cure, I don’t mean to suggest that we aren’t swimming in pollution. We are, to an extent we don’t even have the tools to understand. Throughout the past century, harmful chemicals have been pumped into our air, earth, water, food, and bodies without hesitation, regulation, or, often enough, measurement. Helpless before such malfeasance, we cleanse as if undertaking our own personal Superfund decontamination. If nothing else, it gives us something to do: “You do not have to wait until toxicity is eliminated across the planet,” promises Junger.

He’s wrong, of course. All the expensive nostrums in the world won’t cure us in any meaningful biochemical sense. Some of the worst toxins lodge in our fatty tissues, and to get them out of our bodies, Gershon told me, “you’d need a lipid solvent, something like turpentine or gasoline, the kind of stuff that would dissolve a candle made of paraffin wax.” To get them out of the ecosystem, we’d have to take action on a scale we can’t even imagine right now. This is acutely true in the United States, by the way; other governments in the developed world are registering and banning noxious substances at a rate that seems unthinkable in our fractured polity. Until we actually clean things up, we’ll just have to resort to ritual ablutions.

  1. The Clean Program Diet:

    Breakfast: A protein shake mixed with hemp, rice, coconut, or rice milk.

    lunch: Non-gluten grains; most fruits and vegetables, except for "nightshade" vegetables (tomatoes and eggplant); fish or wild game; nuts and seeds.

    dinner: The same as breakfast.

  2. The Master Cleanse Diet:

    If a man wants to see "the palaces of the angels on high, ... he must fast a number of days and place his head between his knees and whisper many hymns and songs."

    "Here is my body ... may it be an anvil for Thy beatings, to atone for their sins." —Saint Catherine of Siena, fourteenth century holy woman who, from the age of 16, ate only bread, raw vegetables, and water
