Lean and Hard

The Atlantic - 7.19.13 by Paul Offit

At least 15 studies have now shown that vitamin C doesn't treat the common cold.

On October 10, 2011, researchers from the University of Minnesota found that women who took supplemental multivitamins died at rates higher than those who didn't. Two days later, researchers from the Cleveland Clinic found that men who took vitamin E had an increased risk of prostate cancer. "It's been a tough week for vitamins," said Carrie Gann of ABC News.

These findings weren't new. Seven previous studies had already shown that vitamins increased the risk of cancer and heart disease and shortened lives. Still, in 2012, more than half of all Americans took some form of vitamin supplements. What few people realize, however, is that their fascination with vitamins can be traced back to one man. A man who was so spectacularly right that he won two Nobel Prizes and so spectacularly wrong that he was arguably the world's greatest quack.

Thought I'd share this with you, since I'm irritated by the public's gullibility and attraction to fads.

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.”

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.

Inkfish - 1.15.13 by Elizabeth Preston

BluePrintCleanse claims that the energy you save on digestion by not eating any real food gets diverted to "other metabolic processes." But Swoap says this is false. Your whole metabolism will slow at once, not just the tasks attached to digesting food. This will make it harder to lose weight.

Before I learned that it costs $65 to $90 to starve yourself for a day, I considered trying one day's worth of "juice cleansing" to put myself into the proper cranky fog for writing this piece. But if I'm going to eat no calories, I prefer to spend no dollars.

What did I give up by fueling myself on solid foods instead of liquefied produce? Really, one day would have been merely dipping a toe into the celery water. If I were a serious client of a juice cleanse company, I would pay for anywhere from three to ten days' worth of bottled juices, delivered to my doorstep in a cooler every morning.

The first few days of deprivation would, in theory, "cleanse the blood" and release toxins from my tissues that have been slowing me down and making me sick. I'd give my colon a break while "sweeping" it out. The latter days would boost my immune system and "fight off degenerative diseases." After all that detoxifying and boosting, I would feel energized and restored. I might even have lost a few pounds—but it's about health, not weight.

This is what my own experience tells me, not what you'll often read on the web. What are the typical reasons given for why losing the last 10 or 15 pounds seems so hard to do?

I've read the following:

1. Your metabolism slows down as you lose weight so your body resists your weight loss efforts more and more as you approach your goal weight.

Reality: While it's true that you need fewer calories to maintain a lower weight than a higher one, the difference just isn't big enough to significantly put the brakes on your weight loss progress. You've heard that your body goes into a so-called starvation mode, and clings tightly to every calorie. You'd think, hearing this, that your cells are somehow able to hunker down and survive on almost no energy at all. The truth is, you need calories to live, and your cells will continue to burn them as needed to get through the day. So that's not the real reason for your halting forward motion as you try to shed those last few pounds.



2. Your body starts stocking away fat like nobody's business when it senses that its days of plenty are coming to an end.

Again, the reality is that this effect may exist, but it's just not big enough to account for the fact that the last few pounds are holding on to your frame like the movie aliens that wrap their spidery fingers around the heads of their ill-fated victims. You can't seem to pry them loose no matter what you try, but this isn't the fault of some amazing, souped up fat-creating stocking mechanism, No, the culprit tends to be a phenomenon that's far more prosaic.

Here's what happens when you get close to your goal: You start to let up. The psychology of it is easy to understand. It's the same temptation faced by anyone who's oh-so-close to attaining a hard-earned goal. You feel you can afford to give yourself a break. After all, you've attained so much! You deserve to reward yourself. So, you're not quite there yet, so what? A little indulgence can't hurt. And so on. Sound familiar? It does to me, anyway.

Whether or not you really do need a little break before that final push to the finish line is up to you, but the little breaks easily turn into on long, extended vacation. Hence, your goal lies out there unattained like a sparkling pool of water in a desert, forever moving away as you try to get closer.

Does this sound like you?
