Shangri-La Diet for Pets

In March, Century posted this on the SLD forums:

I’d like to put my dog on SLD by giving him his calories through sugar cubes. Would that work?

The dog will whine constantly when he’s hungry. He’s pretty old, and at this point, we don’t have the heart to put him on a strict diet. The hope is that with SLD, we won’t have to choose between a happy dog and a healthy dog. If it works, he won’t whine after he’s been fed his normal serving.

Today he posted this:

It’s worked incredibly well. It’s gotten to the point where he won’t whine at all. If I don’t remember to feed him, he won’t eat anything. I haven’t been able to weigh him, so I don’t really know how much weight he has lost, but a number of people have commented on how much thinner he looks. I’ve started to cut back on the sugar.

Any doubt I’ve had that SLD is for real has been erased. It’s unreal how well it’s worked for the dog.

The Trip of 100 Pounds Lost: How Did it Begin?

Someone named August posted today on the SLD forums that he’d lost 100 pounds:

The scale dipped to 185 a bit unexpectedly this weekend. [He is 6′ 3″.] Well, that was my target. Now what?

100lbs down.

Anticlimatic really. The last three pounds just disappeared overnight.

And I can still stand to lose more, despite having people telling me I shouldn’t lose anymore since last year.

Since he has posted many times, and has been so successful, I think there is a lot to be learned here. Here is some of what he learned along the way.

Are your habits getting in the way?

I had a similar slow start with SLD too. It wasn’t until I realized my habits kept me eating far more than I needed to that I started losing significant amounts of weight.

Bananas: good or bad?

I used to eat bananas everyday for potassium, but within an hour, I’d be really hungry. One day I brought brisket I cooked overnight and I didn’t want to put it in the fridge, so I had it when I usually had my banana. I didn’t think about food again until it was almost time to go home and I realized I hadn’t eaten anything else!

What about sweeteners?

I drink a lot of coffee, and when I decided to drop the sweeteners and take it black, the temptation to eat wheat products practically disappeared.

What about patience?

I began in a very low key way. I simply started trying sugar water, then different oils, and for a while it didn’t seem like it would work. Then one day Seth linked to the guy who ate protein nose clipped. I decided to get a nose clip and try that for a while. It worked in a borderline way, in other words it was effective enough to keep me doing it, but I wasn’t losing very much weight at the time. Eventually, I ended up taking two tablespoons of walnut oil in the morning everyday.

The AS was enough for me to realize I was always eating more than I needed. I’d dig into something and then realize I didn’t need to finish it. My life was built around food. I love to cook and I live by myself, so that means way too many calories in one place. As I started to recognize this, I began to wonder how to change this.

Then on Good Friday I did a fast. I decided that if I started to feel bad, I’d just take some oil. It worked very well. I realized I could get by with very little food.

Thanks to Heidi.

Why One Student Loves Tsinghua University

After reading my post about Reed College’s horrible treatment of Chris Langan, a friend of mine who is a student at Tsinghua University wrote this:

I feel so lucky that we have lots of brilliant scholars who are at the same time good teachers. Many of them do care about undergraduates and give good advice. I don’t know which education system for undergrads [Tsinghua’s or Reed’s] is best, for colleges that do poorly in educating undergrads [like Reed] may produce students who are more independent. But being educated here, I have to say I love Tsinghua and its teachers a lot.

Why does she love Tsinghua? I asked.

I think it is very tolerant. I made many mistakes while I was growing up, but just like my parents, my school didn’t forced me to do anything to correct my mistakes. It gave me freedom to choose, to live my own life. I’m glad it didn’t interrupt my life and gave me the chance to see my mistakes and to correct them by myself. And when I did want to correct them, it allowed me to. I realize that there won’t be many chances to make mistakes and to correct them by myself after I leave school so I value the time in the school. So I guess the best thing about Tsinghua is its freedom and tolerance.

My friend started as a math major. Then she became an English major. Now she is taking economics classes because she wants to study economics in graduate school. That’s what she means by “mistakes”: choosing the wrong major.

Tsinghua versus Reed.

Less Popular than Jesus

John Lennon once said, referring to the Beatles, “ We’re more popular than Jesus.” At dinner last night someone said that Michael Jackson was more popular than the Beatles. That surprised me. Was Michael Jackson more popular than Jesus? Google hits, as of this morning:

  • Beatles: 54,400,000
  • Jesus Christ: 47,600,000
  • Michael Jackson: 41,600,000

For comparison:

  • Barack Obama: 95,800,000
  • Harry Potter: 93,200,000
  • Brad Pitt: 28,200,000

Does that make J. K. Rowling (6,600,000 Google hits) the most powerful person in the world? Unlike President Obama, she can say whatever she wants. And she speaks to the most impressionable people in the world.

Flaxseed Oil and Better Shaving

Roberto Medri, a 27-year-old who works in Italy for Bain & Company, a consulting firm, writes:

I have had bad shaving problems since I started working three years ago. I tried pretty much everything: multiple blades, old-time safety razors, expensive British shaving soaps, silvertip brushes, pre-shaving oil and creams, abstruse shaving methods and blade techniques: all to almost no avail. Instead, my face would bleed more and more every day, making it frustrating and time-expensive to shave, only to get results which ranged from laughable to frightening.

I noticed two patterns:
  • Once in a couple of months, I used to have a perfect shave: fast, enjoyable, baby-butt smooth with no irritation. I was not, however, capable of isolating the deciding variable, as those epiphanies seemed to be completely random.
  • When I took up a new remedy (another pre-shave cream, steamed towels, etc.) things got better for 2-3 shaves, then back to normal horror.
A fortnight ago, I began having perfect shaves. Consistently. I am simplifying my routine because all toners and moisturizers now seem useless. My towels are not stained, I am on time, I actually look forward to shaving every morning (with but only a slight fear of it all ending).

The only explanation I can think of is that, following your advice, I started taking four softgels/day of flax oil about a month ago.

It’s very difficult to get flaxseed oil in Europe (bottled oil simply is not available). I have recommended flax to my colleagues also plagued by red necks to no avail: they are elite in two ways, white collar elite (working for Bain) and dietary elite (as Italians, which supposedly have the best and healthiest food ever), so it fits with your reasoning that they are very change-averse. In fact, a manager told me that my taking softgels during the day is “inappropriate” and “disturbing” colleagues.

The Story of Hyundai: A Lesson in Public Speaking

Hyundai, rhymes with Sunday.

I loved this talk at MIT by John Krafcik, head of Hyundai’s American branch. It lasted an hour; I wished it was longer. It reminded me of Carl Willat‘s Trader Joe’s commercial: Full of emotion, in this case Krafcik’s pride in his company and what they’ve done. Toyota is the world’s number #1 car company; when a Toyota executive interviewed for a job at Hyundai, he told them that at Toyota, they are most afraid of Hyundai. So afraid that they bought five straight years of a certain Hyundai model, took them all apart, and studied how each system changed from year to year. (I used to compare New Yorker articles with their book versions, word by word, to see what the editors changed. John Updike compared two versions of Vladimir Nabokov’s memoir, Conclusive Evidence and Speak, Memory, word by word. More recently I noticed that Zadie Smith’s On Beauty had significant differences between the audio and printed versions.)

Krafcik repeated an old Jay Leno joke: “How do you double the value of a Hyundai? Half-fill the gas tank.” So he had a great story to tell, the return from ignominy, but curiously he barely told it. Probably this was because he was working at Ford at the time. I have no great interest in cars, I’m not particularly interested in why one company does better than another, yet I was entranced. I came away thinking that most of what I’d heard about public speaking was wrong — most of the stuff in Made to Stick, for example. Sure, the advice to tell a story — and most speakers don’t even understand that — is right. Krafcik did tell a story. But that’s the easy part. I think everyone understands what a story is. The harder part is convey emotion. Carl Willat has said to me that in movies, that’s all that matters. Absolutely, and I think what’s he saying applies to talks as well. Of course an academic talk must have content. But the practical lesson for me is that when planning a talk I should pick something I care a lot about and in the talk do my best to convey how I feel. That’s all. Don’t worry about telling a joke, don’t worry about slick visuals, don’t try to impress them.
I plan to show Krafcik’s talk to graduate students (in psychology) because it makes a point I doubt they’ve heard: It’s fine if it’s other people’s work that you feel strongly about. Krafcik isn’t the head of Hyundai. He had nothing to do with their long comeback. But he’s proud of his company — and he conveyed that in spades, and that was enough. Suppose you do research on X. You’re giving a talk about it — perhaps a job talk. Maybe your research is mediocre. But you think research on X is incredibly important. Fine — just make that clear. Everyone in the audience will like you for being able to appreciate the work of others, that’s so rare. When you point them to other work that is great, you’re helping them. Suppose you’re teaching a class. Find the parts of the subject that you feel strongly about. Do your best to convey how strongly you feel. Better positive than negative but negative works. (Ask Nassim Taleb.) Avoid the parts you don’t feel strongly about.

In a sense all speaking (and all writing) is public speaking (unless we’re talking to ourselves, which is rare). The audience might be one person or a hundred people, it doesn’t matter, the principle is the same: We use the emotion in what we hear to judge how much attention we should pay to it. Zero emotion = zero attention. I once visited Alaska. While I was there I took a day trip to a glacier. Near the glacier was a building with a little slide show about the glacier, with a taped narration. It was all very dry — the glacier grows in winter, shrinks in summer, there are these animals nearby — but you could tell the speaker cared a lot about the glacier. I was terribly struck by that. How rare it is to hear someone talk about something they really care about, I thought. I’ve told that story dozens of times. But I didn’t manage to translate it into advice about how to give a talk.

A Perfect Storm of Airport Improvements

I’m flying to Los Angeles today. Three new things — all of them new to me this flight — are making this trip distinctly more pleasant than earlier trips:

1. Southwest has special check-in if you’ve checked in online but have a bag to check. The line went very fast.

2. Crocs shoes. So easy to slip off and on at security.

3. Free Wi-Fi while waiting for flight.

I suppose after a while I’ll get used to this but right now it reminds me of how I felt the first few times I read the NY Times online.

Acne Self-Experimentation: Why It’s Promising

This article reports that there was no acne whatsoever among the Kitava Islanders in Papua New Guinea and the Ache hunter-gatherers in Paraguay. Here is the abstract:

BACKGROUND: In westernized societies, acne vulgaris is a nearly universal skin disease afflicting 79% to 95% of the adolescent population. In men and women older than 25 years, 40% to 54% have some degree of facial acne, and clinical facial acne persists into middle age in 12% of women and 3% of men. Epidemiological evidence suggests that acne incidence rates are considerably lower in nonwesternized societies. Herein we report the prevalence of acne in 2 nonwesternized populations: the Kitavan Islanders of Papua New Guinea and the Aché hunter-gatherers of Paraguay. Additionally, we analyze how elements in nonwesternized environments may influence the development of acne. OBSERVATIONS: Of 1200 Kitavan subjects examined (including 300 aged 15-25 years), no case of acne (grade 1 with multiple comedones or grades 2-4) was observed. Of 115 Aché subjects examined (including 15 aged 15-25 years) over 843 days, no case of active acne (grades 1-4) was observed. CONCLUSIONS: The astonishing difference in acne incidence rates between nonwesternized and fully modernized societies cannot be solely attributed to genetic differences among populations but likely results from differing environmental factors. Identification of these factors may be useful in the treatment of acne in Western populations.

This implies that acne isn’t inevitable. It’s almost surely caused by something environmental — perhaps diet, perhaps something else (such as washing your face with soap). That’s why self-experimentation about acne is promising: By changing your environment in various ways, you may be able to figure out what’s causing your acne.

The Pashler-Roberts Law: Expense versus Honesty

In this post Andrew Gelman comments on my recent post about acne self-experimentation. He makes an excellent point about drug-company studies:

How would you want to evaluate the risks and effectiveness of a new drug that was developed by a pharmaceutical company at the cost of millions of dollars? I’d be suspicious of an observational study: even if conducted by professionals, there just seem to be too many ways for things to be biased.

Right. And it’s not just observational studies. The data from any big study can be analyzed many ways. The more at stake, the greater the chance of what Andrew calls bias and I call making choices that favor the result you prefer. Independently of Andrew, Hal Pashler and I came up with what I call the Pashler-Roberts Law: The more expensive the research, the less likely the researchers will be honest about it.

You may remember that Robert Gallo, the AIDS researcher, did very expensive research. The deception (possibly self-deception) that accompanied very expensive fusion research is described in Charles Seife’s Sun in a Bottle: The Strange History of Fusion and the Science of Wishful Thinking (2008).

As Andrew says, this is a big virtue of self-experimentation. Because it’s free, it’s easy to be honest, especially about failure. The cheaper the better is a broad truth about science that’s hard to learn from books or classes or even talking to scientists.
