100 hours of juice fast.

Chard, orange, mango juice.

So, perhaps unsurprisingly, we broke the juice fast a little early. We aimed to go for one week, but stopped after four days. The main reason, if you’ll believe us, is that we were bored. Eating good food is one of the most important and interesting parts of our lives, and fruit and vegetable juices just don’t provide the same variety of tastes (and, of course, textures) that we require to keep ourselves entertained. Juice fasting is also kind of a damper for your social life, since (at least for us) socializing often revolves around food. We even had to skip out on Jon’s work’s holiday party, since we didn’t want to stand around and just watch people eat and drink.

Otherwise, juice fasting turns out to be pretty easily doable. Aside from the boringness of it, the other main issue was simply dealing with hunger. For the first two days, I was hungry a lot of the time, and that was just an unpleasant sensation for which I had not been prepared.  After the second day, I wasn’t hungry so much, and my appetite seemed significantly decreased.

However, I never experienced any of the detox effects – extra energy, clarity, etc. – that many people claim to get from juice fasting. Instead, I had a lot of hunger at first, and then I was just easily tired and constantly cold. I also didn’t seem to get any great cleansing in the digestive department. I took one tablespoon of psyllium husks each morning, thinking that the added fiber would help keep my digestion regular, but it had little effect for me.

In terms of weight loss, Jon and I each lost about five pounds in four days. For me, and if our scale is to be believed, most of that was fat. Since we started eating solid food again in the past couple days, I’ve gained about two pounds back (again, fat).

Everyone warns you to be careful about breaking your fast, and ease out of it with small amounts of plant-based foods. We thought about that, but then threw caution to the wind and went to our favorite taqueria to eat quesadillas and crispy nachos. Then, I got a terrible headache and felt horrible. So I wouldn’t do that again. But it does seem to be the case that my decreased appetite is sticking around — even four days after breaking the juice fast, I’m definitely eating smaller amounts of food than I was before. Considering that self-control in the quantity department is probably my biggest challenge in terms of eating healthily, that seems like a pretty good payoff for the effort I put into juice fasting for four days.

I might try juice fasting again in the future, and/or just substituting a juice for a meal once in a while. If I do a full-on fast again, I will probably try to do more research in preparation, since this time we just kind of intuited our way through, with a little help from Google. It was definitely a great way to efficiently consume a lot of fruits and vegetables. I do highly recommend the juicer we got, the Omega J8004 – it was easy to use, easy to clean, take apart, and put back together, and worked well for everything we tried putting in there.

Apple juice is bad for you.

That’s the conclusion of the Associated Press, which blames high calories, not dangerous arsenic levels. All the more reason to prefer cider, right?

Regardless of the dangers of juice, Jon and I are embarking on an under-prepared foray into juice fasting, inspired by our recent watching of the documentary Fat, Sick, and Nearly Dead (which is currently free to watch on Netflix or Amazon Prime). We’ll see how long we last. I’ve noticed I’ve been feeling almost constantly hungry for the past couple days, ever since we put in our order for our new juicer, in anticipation of the coming deprivations, I guess.

Bottoms up!

Juice fast begins!


The problems of libertarian futurism.

The November 28 issue of the New Yorker had a great George Packer piece on the PayPal billionaire Peter Thiel: “Peter Thiel’s Rise to Wealth and Libertarian Futurism” (subscription required). I had previously known of Thiel primarily as the guy who was offering money to college-aged kids to not go to college – his Thiel Fellowship offers $100,000 to young folks (under 20) for a two-year period, during which time the Fellows “focus on their work, their research, and their self-education.”

In the article, Thiel does not come across as rabidly anti-education as his public image suggests. To me, Thiel and his friends as depicted in Packer’s article do not seem to have a very coherent or persuasive case against higher education as an institution – there are vague intimations that universities make you conformist, but I find that pretty unpersuasive (and why stop at universities? Why not high school, middle school, elementary school, or kindergarten?) At a dinner party described in the article, one of Thiel’s friends says he was failed by an English teacher who said he couldn’t write – but this sounds like the problem of one bad apple in the education system, a flaw that the business world certainly isn’t immune to. (Interestingly, another anti-education friend at this dinner party is AI researcher Eliezer Yudkowsky, author of an elaborate Harry Potter fanfic called “Harry Potter and the Methods of Rationality.”)

The Thiel Fellowship website reflects a more nuanced view, to a certain extent: the site’s page on “the education bubble” focuses on the unethical burdening of young people with untenable student loan debt. I think that’s a very legitimate public policy concern, but of course, it does not follow that everyone should skip college and launch high-tech startups.

In general, this is the story of each libertarian position taken by Thiel, and the problem with libertarianism in general: you start with a extreme position of “free choice,” but are forced to walk it back with caveats and conditions once you learn more about the complexities of the problem. Packer’s article illustrates this a few times, once concerning one of my favorite hobby-horses – the myth of political correctness run rampant on college campuses. In 1995, Thiel, who is gay, co-authored The Diversity Myth, which in part discussed the case of a Stanford law student named Keith Rabois who shouted “Faggot! Faggot! Hope you die of AIDS!” outside an instructor’s on-campus residence – a provocation which earned Rabois’ ejection from Stanford. According to Packer, Thiel (along with his co-author David Sacks) characterized the Rabois case in The Diversity Myth as one “of individual courage in the face of a witch hunt,” and which challenged “fundamental taboos.” Now, apparently, Thiel regrets writing about the incident, telling Packer:

All of the identity-related things are in my mind much more nuanced. I think there is a gay experience, I think there is a black experience, I think there is a woman’s experience that is meaningfully different.

It’s nice to see an example of an ideological libertarian observing and learning something about the reality of the world we inhabit. However, it’s less inspiring to see Thiel shy away from issues, like energy policy or climate change, with live political implications – it seems like he just thinks political problems are too hard. To say, as he does, that “it would be good if we had a less political world,” is like saying “it would be good if we had a less money-driven world” – it’s an impossible utopia. But the failure to recognize that we live in an observably more money-driven world than a politics-driven world shows a shocking disconnect from reality which is, in my view, the fundamental problem of libertarianism.

I can agree with Thiel on futurism, or technological optimism, anyway. Packer notes the Founders Fund manifesto, “What Happened to the Future?” the tagline of which seems to be: “We wanted flying cars, instead we got 140 characters.” Even through (or maybe even because of) the dot-com boom(s), society’s technological imagination has been meager, seeming to top out at micro-blogging and FarmVille. (Although I’d quibble with the line, “Instead of Captain Kirk and the USS Enterprise, we got the Priceline Negotiator and a cheap flight to Cabo,” since we are clearly seeing the beginnings of a robust market in TNG-era flat screen tablets.) Thiel is adept with his science fiction commentaries:

The anthology of the top twenty-five sci-fi stories in 1970 was, like, ‘Me and my friend the robot went for a walk on the moon,’ and in 2008 it was, like, ‘The galaxy is run by a fundamentalist Islamic confederacy, and there are people who are hunting planets and killing them for fun.’

(Is that a real story? Or shall I write it?) Note also, of course, that in the Star Trek universe, the Federation has progressed past currency, making “entrepreneurship” obsolete.


Apple’s Siri is anti-choice and pro-breeding.

Despite what you might have read, Apple’s virtual assistant iPhone program, Siri, is not “pro-life”, and no one is accusing it of such.* Instead, Siri is simply obfuscatory, with apparent anti-choice biases.

The last couple of links address some of the gender- and reproductive freedom-based reasons that we should care about Siri’s poor response to abortion inquiries. Another angle, apparently lost on, for example, Ars Technica commenters, is the net neutrality angle. I was pleased to notice that Sen. Blumenthal, of my home state of Connecticut, has already addressed this.

Abortion is not the only controversial issue that Siri weighs in on. Over the Thanksgiving weekend, my little cousin was trying out Siri and asked her where she could get a dog. Siri responded that she couldn’t find any dog breeders in the area, and didn’t even search for animals shelters or rescue groups! (Of course, I was quick to remind my cousin that dog breeders are not the only source for adopting a dog.)

Obviously, a perfectly neutral online information environment is probably impossible, and no one is saying that you should be free to leave your common sense at home when you have your iPhone in your pocket, but the specifically addressable issue here is that Siri is being bamboozled – like many women are – by so-called “crisis pregnancy centers.”

* It’s pretty disappointing to me that Ars Technica, usually a great source of tech news, not only wholly fabricated the act (of accusing) described in the headline and chose to characterize the abortion access issue as a matter of being “pro-life,” but even went so far as to put “pro-life” in quotes – suggesting that the groups named in the article (ACLU, NARAL) had been quoted as making the charge using the specific term “pro-life.” In fact, neither ACLU’s blog post or NARAL’s statement ever accuses Apple/Siri of being pro-life, or even uses the term. The Ars article links to this Abortioneers post, saying that “the paucity of responses in the area of pregnancy and birth control have raised concerns that Siri is programmed to be ‘pro-life.'” Of course, no such concern is expressed in that post, which describes the poor search results as “fishy.” It’s a bit of a stretch to say that calling something “fishy” is the same thing as raising concerns about being pro-life. In fact, the only major source I could find that used the phrase “pro-life” in discussing the issue was this Slate post. And although the Slate post doesn’t make any claims that Siri is, in fact, pro-life – it merely discusses that people are concerned – the AOL-owned blog TUAW triumphantly linked to Slate in its own post, called, inaccurately enough, “Debunked: Ridiculous claims of ‘pro-life’ bias in Siri.”

In conclusion to this footnote that has overwhelmed the blog post, words matter, and people who write for a living should be a little more careful when using them.


The brick and mortar opticians’ cabal.

Have you heard of Warby Parker? Or Lookmatic? They’re just two of a bunch of new companies that sell cheap and stylish prescription eyeglasses online. Warby Parker is my favorite, because of their marketing slickness, Tom’s-style buy-one, give-one do-gooding, and the fact that they’ll send you five pairs of frames (for free!) to try on in the comfort and privacy of your home before you make a selection. If you try them, know before you go to your eye doctor that you need your “pupillary distance” or “PD” measure, and it’ll save you a lot of hassle. I went through this hassle, and it seems like a good example to me of a broken regulatory system and anticompetitive market, so I cannot resist boring the Internet with my story:

I’d decided a few months ago to get new glasses because I was sick of my current pair and because the insurance I had through my fellowship covered an eye exam. Before I moved to California (and before that insurance ran out), I got a new prescription for eyeglasses at an eye doctor in D.C. A few weeks ago, I ordered a home try-on kit from Warby Parker and spent a couple days being indecisive about what pair of frames to choose. After I finally made a decision, I dug up my prescription to enter it into the Warby Parker site, when I discovered that my eye doctor had not included a PD measure. Apparently, this is common, and the Warby Parker site suggested that I go back to my eye doctor to get my PD measure. In my case, since my eye doctor was across the country and I didn’t want to pay for another eye exam, this wasn’t really an option. The website also made two other suggestions: I could try to see if the last place I had glasses made had my PD on file, or go to a local optician and see if they would measure my PD (possibly for a nominal fee). The copy on the Warby Parker page was actually pretty interesting:

You can also try to walk into an optical shop and ask for a PD measurement. In the past, most optical shops provided PD measurements for free, but now we’re finding that many are no longer doing so in a vain attempt to maintain control of the market and prevent people from buying online.

That made me think that the local LensCrafters store was not going to be happy about measuring my PD (trivial though the process is). So my first thought was to call the Pearle Vision store where I had bought my last pair of glasses to see if they would just tell me my PD. The woman who spoke to me on the phone told me that an email had gone around about these online opticians, and that she could not give me my PD measurement information. When I asked her if there was any way I could request its release to me, since it was mine, she said, “No, it’s not yours, it’s the lab’s.”

Plan B was to try calling the local LensCrafters. After I explained my situation to the guy on the phone, he tried to dissuade me from buying glasses online at all, saying that the PD measurement was likely to be inaccurate if I had a strong prescription and they didn’t have the actual frames on me to measure them. When I told him I’d take my chances, he suddenly remembered that the store’s pupillometer was broken and that I could try my luck at a different LensCrafters. (So if you’re thinking of waltzing into the LensCrafters in Emeryville, don’t bother! Their pupillometer is broken and they are apparently ethically bound to taking only the most precise PD measurements before any eyewear changes hands. [Just kidding! Opticians don’t have professional ethics.])

In the end, I wound up paying $25 for the optometrists-in-training at the UC Berkeley Eye Center to measure my PD. I guess they’re more of a medical school than a member of the brick and mortar opticians’ cabal, so they don’t really have a dog in this fight.

When I sat down to write this blog post, I did a little Googling and discovered that there really is a brick and mortar opticians’ cabal. It’s called Luxottica:

It owns LensCrafters, Pearle Vision, Sunglass Hut, and the optical shops in Target (TGT) and Sears; (SHLD) it owns Ray-Ban, Oakley, and Oliver Peoples; it manufactures, under license, eyewear for more than 20 top brands, including Chanel, Burberry, Prada, and Stella McCartney. “They’ve created the illusion of choice,” says [Warby Parker co-founder] Gilboa. And inadvertently they’ve created an opening for an indie anti-brand brand such as Warby Parker. Luxottica declined to comment.

…Warby Parker uses the same materials and the same Chinese factories as Luxottica. It can sell its glasses for less because it doesn’t have to pay licensing fees, which can be as much as 15 percent of the $100 wholesale cost of a pair of glasses. Warby Parker doesn’t have to deal with retailers, either, whose markups can double or triple prices, it says. And at least for now, the founders are content with lower margins.

So, Warby Parker and co. are full of win, right? They simply seem to have the superior business model; if the market works at all, then surely the pathetic and apparently-coordinated attempts at Luxottica outlets to resist progress through noncooperation will ultimately prove futile. Well, I’m not as optimistic about the market as some, but we’ll see.
