In March 2023, the Japanese medical authorities introduced that the brand new weight reduction drug Wegovy—which was in staggering demand the world over, inflicting shortages in all places—had been permitted to deal with weight problems of their nation. It sounded, at first look, like nice information for Novo Nordisk, the corporate that makes Ozempic and Wegovy. However business outlet the Pharma Letter defined that this may not the truth is transform a lot of a lift. They predicted that these medicine would dominate the market in Japan, however that gained’t imply a lot, for a easy purpose: there’s nearly no weight problems there. Some 42% of Individuals are overweight, in contrast with simply 4.5% of Japanese folks. Japan, it appears, is the land that doesn’t want Ozempic.
I puzzled how this could possibly be, and if the reply would possibly supply me a manner out of a dilemma that was obsessing me. A number of months earlier than, I had began taking Ozempic, and I used to be touring all around the world to interview the main specialists on these medicine to analysis my new ebook, Magic Tablet: The Extraordinary Advantages and Disturbing Dangers of the New Weight-Loss Medication. The extra I found, the extra torn I turned. I had realized there are huge well being advantages to reversing weight problems with these medicine: for instance, Novo Nordisk ran a trial that discovered weekly injections diminished the chance of coronary heart assault or stroke by 20% for individuals with a BMI over 27 and a historical past of cardiac occasions. However I additionally noticed there are important dangers. I interviewed prestigious French scientists who fear the medicine might trigger a rise in thyroid most cancers, and consuming problems specialists who fear it can trigger an increase on this downside. Different specialists worry it might trigger despair or suicidal ideas. These claims are all fiercely disputed and debated. I felt trapped between two dangerous decisions—ongoing weight problems, or medicine with numerous unknowns.
So I went to Japan, to find: how did they keep away from this entice? My first assumption was that the Japanese should have gained the genetic lottery—there needed to be one thing of their DNA that makes them keep so slim. However within the late nineteenth and early twentieth century, giant numbers of Japanese staff migrated to Hawaii and so they have now been dwelling on the island for 4 generations. They’re genetically similar to the Japanese individuals who didn’t depart. It seems that after 100 or so years, Japanese Hawaiians are actually nearly as chubby because the folks they stay amongst. Some 18.1% of them are overweight, in comparison with 24.5% of Hawaiians general. Meaning Japanese Hawaiians are 4 occasions extra more likely to be overweight than folks again in Japan. So one thing aside from genes explains Japan’s slimness. However what?
I glimpsed a part of the reason after I went to the Tokyo School of Sushi & Washoku, to interview the president Masaru Watanabe, who I additionally spoke with on Zoom on one other event. He had agreed to prepare dinner a meal for me with a few of his trainees, and to elucidate the ideas behind it. He instructed me: “The Japanese delicacies’s [core] function is simplicity. For us, the easier, the higher.”
He started to make a typical Japanese meal, the type folks had been consuming all around the nation that lunchtime. He and his cooks grilled a mackerel, boiled some rice, made some miso soup, and ready some pickles. “We don’t historically eat meat so much. We’re an island nation. We admire fish.” Because the mackerel was grilled, I watched as numerous oils and fat leeched out. Much more importantly, Masaru defined, this was an illustration of one of many essential ideas of Japanese cooking. Western cooking, he stated, is primarily about “including.” To make meals tasty, you add butter, lemon, herbs, sauces, all types of chemical substances. “However the Japanese type is completely the other.” It’s “a minus delicacies.” It’s about drawing out the innate taste, “to not add something additional,” he stated. The entire level is to strive “to make as a lot as doable of the substances’ pure style.” To Japanese cooks, much less is extra.
He additionally stated Japanese meals have very small parts, however extra of them—5 in a typical meal. Earlier than we began to eat, Masaru defined the Japanese ideas of consuming. The very first thing I needed to study was “triangle consuming.” All my life, after I was consuming a meal with completely different parts, I’d principally eat them sequentially—begin the soup, end the soup; begin the salad, end the salad; begin the pasta, end the pasta. “In Japan, that is thought to be actually bizarre,” he stated. “It’s a impolite manner of consuming.” A meal like this must be eaten in a triangle form. “First, drink the soup a bit of bit, then go to the facet dish—one chunk. Then strive the rice, for one chunk. Then the mackerel—once more, a single mouthful. Then return and have one other style of the soup,” he stated. “That is additionally the important thing to maintain you wholesome … Maintaining the stability, so that you don’t eat an excessive amount of.”
The second factor we needed to study is when to cease. In Japan, you’re taught from a really early age to solely eat till you’re feeling you’re 80% full. It takes time on your physique to sense you’ve had sufficient, and in case you hit a way of fullness if you are nonetheless consuming, you then’ve positively had an excessive amount of.
I ate nothing however Japanese meals like this on my journey, and three days in, I started to expertise an odd combination of hope and humiliation. I felt more healthy and lighter, however I additionally thought—the Japanese folks have constructed up a very completely different relationship to meals over hundreds of years, in methods we are able to’t probably import. So I used to be stunned to study that the majority of Japan’s meals tradition was invented very not too long ago—in dwelling reminiscence, the truth is. Barak Kushner, who’s professor of East Asian Historical past on the College of Cambridge, instructed the author Bee Wilson, for her ebook First Chunk, that till the Nineteen Twenties, Japanese cooking was simply “not superb.” Contemporary fish was eaten solely as soon as every week, the eating regimen was dangerously low in protein, and stewing or stir-frying weren’t a lot of a factor. Life expectancy was a mere 43. It was solely when Imperial Japan was creating a military to assault different components of Asia {that a} new meals tradition started to be invented, fairly consciously, to supply more healthy troopers. After the defeat of Japan within the Second World Battle, when the nation was in ruins, the brand new democratic authorities stepped up this transformation.
To search out out how Japan created a radically completely different meals tradition, I arrived at Koenji Gakuen Faculty with my translator on a stiflingly scorching September morning. It’s a typical faculty for teenagers aged from 5 to 18 in a middle-class neighborhood in Tokyo. We had been greeted close to the doorway by Harumi Tatebe, a girl in her early 50s, who had been the nutritionist there for 3 years. As we walked by means of the corridors, children waved at her affectionately, and shouted her title, desirous to know what they had been having for lunch that day. By regulation, Harumi stated, each Japanese faculty has to make use of an expert like her. It took her three years to qualify, on high of her instructing diploma, and he or she defined that on this place, you will have a number of vital roles to play. You design the college meals, according to strict guidelines stipulating that they have to be contemporary and wholesome. You oversee the cooking of the meals. You then use these meals to teach the kids about vitamin. Then you definitely educate their dad and mom on the identical subject.

Harumi instructed me that immediately’s meal consisted of 5 small parts: some white fish, a bowl of noodles with greens, milk, some sticky white rice, and a tiny dollop of candy paste. All the children eat the identical meal, and packed lunches are forbidden. No processed or frozen meals ever goes into any of the meals right here. “We begin from scratch,” she stated. “It’s all about vitamin … Generally with frozen meals, they use plenty of synthetic components.”
As soon as the meal was prepared, Harumi carried a tray over to the workplace of the college’s head, Minoru Tanaka. It’s a authorized requirement that the principal of every faculty ensures lunches meet dietary pointers. It’s additionally customary for principals to have the identical lunch as the children and to eat it first, to verify it’s protected, nutritious, and scrumptious. He rolled up his sleeves and dug in. After a second, he nodded approvingly. Earlier than they started to eat, a baby stood on the entrance of the category and browse out what immediately’s meal was, which a part of Japan it got here from, and the way the completely different parts are good on your well being. She then stated “Meshiagare!,” the Japanese equal of “bon appétit,” and everybody applauded.
Whereas the children had been consuming, Harumi held up some coloured ropes. Each represented a special type of meals you should be wholesome. On today, she held up the yellow rope, representing carbs, and requested what they do on your well being. A toddler yelled: “Offer you power!” She held up the pink rope, representing calcium, and a baby yelled that it makes your bones stronger. As she went although the meals teams, she tied every rope collectively, to indicate that together they make a wholesome meal. “By way of the college lunches, we clarify the meals itself,” the principal, Mr. Tanaka, instructed me.
As I walked round, I had a nagging sense that there was one thing uncommon about this place. Nevertheless it was solely after just a few hours that I spotted what it was. There have been no chubby youngsters. None. My translator and I walked from class to class, asking the children what they most preferred to eat. The primary little one I spoke to, a 10-year previous lady, stated: “I like inexperienced greens, like broccoli.” One 11-year old-boy instructed me he loves rice as a result of “the rice has protein. In the event you eat balanced meals each meal, then you will have a really sturdy physique,” and he flexed his tiny biceps, and giggled.
I requested my translator: Is that this a joke? Are they trolling me? A bunch of 10-year-olds, telling me how a lot they love broccoli and rice? However a lot of the Japanese folks I mentioned this with had been puzzled to see that I used to be puzzled. We train children to take pleasure in wholesome meals, they defined. Don’t you?
Up till this level, I had seen features of Japan’s strategy towards well being that appeared completely admirable. However subsequent, I noticed one thing that left me with blended emotions. In 2008, the Japanese authorities seen that weight problems was barely rising. In order that they launched the “Metabo Legislation,” which was designed to scale back the destructive penalties of a big waistline. The regulation contained a easy rule. Yearly, each office and native authorities in Japan has to usher in a group of nurses and medical doctors to measure the waistline of adults between ages 40 and 74. If the measurements are above a sure degree, the particular person is referred to counseling, and workplaces draw up well being plans with staff to shed some pounds. Firms with fattening work forces can face fines.
I couldn’t think about how this might probably work, so I went to see it in observe. An organization known as Tanita agreed to let me discuss to their staff about it, and to see the measures they’ve put in place. They make vegan meals, wholesome meal replacements, and train gear, so they’re particularly eager to advertise a wholesome Japan. Completely different firms keep according to the Metabo Legislation in several methods, and Tanita is on the most enthusiastic edge.
The primary particular person I met with was Junya Nagasawa, the corporate’s boss. He’s a good-looking 57-year-old who persistently comes high of the corporate’s strolling league desk, with practically 20,000 steps a day. When the Metabo Legislation got here into drive, he instructed me, there was a sudden demand from firms for applied sciences that might assist them monitor their worker’s well being and discover methods to enhance it, so Tanita designed video screens and well being surveillance techniques. Everybody within the firm wears a watch that tracks what number of steps they stroll a day, and while you arrive at work on daily basis, it tells you the way a lot you’ve walked—and the way a lot your colleagues have walked. You might be inspired to put up images of all of your meals, and pledges for a way you’ll enhance your well being—that are, once more, seen to all the firm.
Nagasawa instructed me these measures meant he began to stroll way more. “It’s not tough to stroll, but it surely’s very tough to make the time,” he stated. Now, he will get up earlier, and will get off the subway 4 stops sooner to stroll the remainder of the way in which. “I needed to be the position mannequin,” he stated.
I spoke with a few of his staff. The 33-year-old Yusuke Nagira instructed me he got here to work right here straight from college, and he had by no means accomplished something to take care of his well being as much as that time. “I’d eat no matter I needed to eat and didn’t train in any respect. That was my life-style.” However he seen from logging his weight that he was placing on kilos, and he was aware of the looming annual well being checks. So he made some adjustments. Earlier than, “after I was watching TV, I’d normally eat junk meals or snacks.” He lower them out utterly. And “after I exit to different locations, I strive to not use trains or drive, however stroll.” Realizing he’ll be accountable helps him, he stated. I heard this many times from the employees.
I instructed all of the Japanese folks I talked to that in case you tried this within the U.S. or Britain, folks could be outraged and burn down their places of work. They invariably seemed puzzled, and requested me why. I stated that individuals would really feel prefer it was not their employer’s enterprise what they weighed, and that it was a monstrous intrusion of their privateness. Most of them nodded politely, stated nothing, and checked out me like I used to be barely loopy. Nagira stated merely: “Being fats just isn’t good.” I felt like I used to be speaking throughout a cultural chasm. No matter you consider its ethics, the Metabo Legislation does appear to be—together with Japan’s different measures—having an affect. Its weight problems charge is at present the bottom degree within the wealthy world.
As I traveled throughout the nation, I started to see what you acquire in case you stay within the Japanese type. Each morning round 7 or 8 a.m., in parks throughout Japan, aged folks collect in teams and train collectively. You possibly can watch folks of their 80s and 90s dancing or doing yoga. Japanese folks stay longer than anybody else on earth. On common, males stay to be 81, and ladies attain 88. Much more importantly, they continue to be wholesome for longer.
I went to Okinawa, an archipelago of islands within the far south of the nation, to trace down someplace that sounds nearly legendary—a spot that’s described by native Japanese authorities because the village with the oldest inhabitants on this planet (although one other village in Japan has not too long ago been declared the oldest within the nation). By the facet of a lush tree-covered mountain, we drove into Ogimi. It has 215 households, and 173 folks there are aged 90 or older. The individuals who stay right here have had laborious lives—they had been principally poor farmers, and through the Second World Battle, within the area of simply three months, roughly a 3rd of the inhabitants was killed through the Battle of Okinawa.
Of their little concrete neighborhood heart, a few of the very aged residents had been arriving, trying ahead to catching up with one another, taking part in video games and exercising collectively. The primary particular person we met was Matsu Fukuchi, a 102-year-old lady, who had walked to the middle from her residence, slowly however and not using a stoop, holding on to a cane. Her eyes watched us with curiosity. She stated she took plenty of pleasure in life. “I get along with my grandchildren and have enjoyable, and dance. I really like to bounce.”
Some conventional Okinawan music started to play, and Matsu placed on a brightly coloured kimono. Then slowly, rigorously, joyfully, she stood up, and commenced to bounce. She moved her hips gently in time with the music, and the opposite ladies matched her rhythm, waving their arms. She seemed towards me, beaming.
As I watched these centenarian ladies transfer with the music, I spotted—this is what this entire journey has been about. Whereas she waved her 102-year-old hips in my course, I assumed: That is the potential prize right here, if we are able to resolve the weight problems disaster. Extra life. Extra well being. Extra years of pleasure.
All of a sudden, the sheer artificiality of the weight problems disaster appeared clear to me, greater than at another level on this journey. It’s created by the way in which we stay. It must be doable, due to this fact, to un-create it. However how can we try this? At first look, the hole between us and the Japanese appeared unbridgeable. However then I considered one thing from my very own childhood. If I might take a youngster again to the Britain or the U.S. of the Nineteen Eighties, they’d be astonished by one behavior. Folks smoked cigarettes in all places. They smoked in eating places. They smoked on planes. They smoked on recreation exhibits. If you went to see the physician, he would smoke whereas he examined you. (I’m not kidding: I bear in mind this occurring.) In the event you had stated to folks then that inside a era, smoking would come to appear to be a factor of the previous, we’d not have believed you. In 1982, for instance, 33% of women and men within the Minnesota Coronary heart Survey had been people who smoke. Right now, solely 12% of the U.S. inhabitants smokes cigarettes, and it’s falling additional.
I had requested Masaru Watanabe, the Japanese chef, if it was doable for Westerners to turn out to be just like the Japanese. “I hope so,” he stated. “I positively suppose so,” he clarified. I’ve traveled to many alternative components of the world the place they’ve begun adjustments that convey us nearer to Japanese ranges of well being. In Mexico, they launched a sugary-drinks tax. In Amsterdam, they restricted sugary drinks from faculties and gave chubby children customized well being coaches, slashing childhood weight problems by 12% between 2012 and 2018 (although it has ticked up since). In numerous U.S. cities, there are “meals is drugs” packages. There are dozens of social adjustments we might make that would cut back the large forces driving up weight problems.
None of this, within the brief time period, can get me out of the dilemmas posed proper now by the brand new weight reduction medicine. Within the U.S. and different wealthy nations (aside from Japan), many people must weigh the dangers of constant to be chubby, in opposition to the dangers of taking these medicine. I’m persevering with to take Wegovy, however with a heavy sense of concern concerning the potential risks. But Japan exhibits us that if we make the suitable social adjustments now, we are able to free our youngsters of this dilemma. If we glance East, we’ll notice we don’t should be trapped within the selection between Wegovy versus weight acquire eternally.
