Took 3 tbsp of flaxseed oil this morning and held my nose and drank the oil w/water. It worked! I had brought food for work, I didn’t eat hardly any of it. And I didn’t think about losing weight all day, first time in all my life….
As far as I’m concerned, it never gets old.
Unfamiliar foods cause weight loss, says the theory behind the Shangri-La Diet. If you add enough spices to a food, it will become unfamiliar.An ice cream store in San Francisco called Humphrey Slocombe has some of the world’s strangest flavors, likely to be unfamiliar until you eat them many times.
Their flavors include Eight Ball Stout, Pink Grapefruit Tarragon, Carrot Mango, Russian Imperial Stout, White Chocolate Lavender. Here’s what happened when the owners ate a lot of them:
In the store’s first few months, Godby and his business partner, Sean Vahey, scooped from noon to 9 each night, ate nothing but ice cream, traded the leftover brownies for cocktails at a dive bar called Dirty Thieves and still lost weight. Since then they’ve hired eight employees and — hazard of the job — each gained back the 10 pounds they’d lost.

Long ago Paul Ehrlich, a Stanford professor, wrote The Population Bomb. Yet you probably know about the demographic transition: A sharp decrease in family size when countries reach a certain level of wealth. Which implies a big problem with Ehrlich’s forecasts. You probably don’t know about three related transitions:
1. Forests. For a long time humans destroyed forests and forest area decreased. More recently, however, forests have been regrowing as people leave rural areas for cities.
2. Obesity. In poor countries, rich people are fatter than poor people. In rich countries, the opposite is true: the poor are fatter than the rich, presumably because the rich eat less factory food.
3. Fast food. On a recent visit to Tokyo, I was told that the number of fast food restaurants in Tokyo is declining.
The theory behind the Shangri-La Diet predicts that new food is less fattening than familiar food. At the center of the theory is the idea that smell-calorie associations raise the set point. New food is less fattening because its smell is less associated with calories. This prediction explained why I often lost weight after visiting foreign countries, but not after visiting other places in America.
A few days ago, I got an email from a 40-year-old man who has taken this a step further:
I’ve developed a variant of your diet which works really well for me, and which I haven’t read about so much on your blog, so I thought you might be interested. I live in NYC, and I’m obsessed about different foods. I’m constantly on the hunt for new restaurants, novel ethnic cuisines I’ve never had, etc, and NYC is a great place to indulge this hobby. A couple of years ago I was about 210 lbs, which on my 6′0 frame is at least 30 lbs overweight. I read your book, and tried the oil, etc, and it worked well for me, but it felt like a lot of trouble, and I was actually dropping weight faster than would normally be considered healthy. So I changed the strategy, and simply made up a rule, never to eat the same thing twice.
If I want to lose weight, I follow the rule religiously. I go to different restaurants, order radically different things off the menu, choose unfamiliar beers, wines, cocktails etc when I’m out at bars and clubs. If I follow the rule 100% of the time, I drop about 1 lb per week consistently. If I “cheat” one or two meals a week, I maintain my weight. Any more than that and I slowly gain weight. I’m currently 179 lbs, and have been between 175 and 185 for about two years. Although I’m active, I’m no gym rat, and this “system” is the only nod towards a healthy lifestyle I’ve made during that time. Apart from never repeating a meal, I eat and drink whatever I feel like.
The dose-response relationship (the more he does it, the bigger the effect) makes other explanations less plausible. He later added:
One thing I forgot, which is important, is I absolutely don’t eat when I’m not hungry, and I’ve never had a problem walking away from food if I’m full. Some people might have problems with that, I guess. Also it requires more discipline than I made it sound. Especially when you’re busy, it’s very tempting to hit the same lunch spot every day.
A woman named Melissa Francis recently thanked me for helping her quit smoking. I was surprised. She said she had applied the ideas behind the Shangri-La Diet to smoking. At the center of SLD is the idea that we learn to associate the flavors (smells) of foods with the calories they contain. If you reduce your exposure to those associations, you lose weight.
Francis took this to suggest that the reason people smoke has a lot to do with the association between the flavors (smells) of smoking and nicotine. If she could reduce her exposure to those associations, it should be much easier to quit. So she did two things: 1. Smoked nicotine-free cigarettes (brand name Quest). 2. Used a nicotine patch. The second thing corresponds to ingestion of smell-free calories, such as sugar water or extra-light olive oil or any food nose-clipped (classic SLD). The first corresponds to exposing yourself to the flavors of foods without swallowing them, an experience whose effects you can read about on the SLD forums here and here. Learning researchers know that uncorrelating the CS (e.g., smell) and US (e.g., nicotine), as Francis did, is a great way to reduce the association between them.
Francis had previously tried to quit using nicotine-free cigarettes alone. She had failed. She had previously tried to quit using nicotine patches alone. She had failed. With the combination (Quest 3 and 21 mg patch), however, she was successful. “I stopped smoking the cigarettes pretty much altogether within a week or so. From that point, I just stepped down on the patch over the course of five or six weeks,” she wrote. How easy that sounds! My college advisor told me that quitting smoking was the hardest thing she’d ever done. Francis had been smoking twenty years and smoked about a pack a day. She’d quite for two years about fifteen years ago.
Francis had the idea herself and hadn’t of anyone else doing this. The closest precedent seems to be the work of a Duke researcher named Jed Rose, for example this study.
