In March 2023, the Japanese medical authorities introduced that the brand new weight loss drug Wegovy—which was in staggering demand the world over, inflicting shortages everywhere—had been accepted 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 explained that this could not in reality turn into 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 cause: there may be nearly no weight problems there. Some 42% of Individuals are overweight, in contrast with just 4.5% of Japanese individuals. Japan, it appears, is the land that doesn’t want Ozempic.
I questioned how this could possibly be, and if the reply may supply me a approach 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 Pill: The Extraordinary Benefits and Disturbing Risks of the New Weight-Loss Drugs. The extra I found, the extra torn I turned. I had discovered there are large well being advantages to reversing weight problems with these medicine: for instance, Novo Nordisk ran a trial that discovered weekly injections diminished the danger of coronary heart assault or stroke by 20% for contributors 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 may trigger a rise in thyroid most cancers, and eating disorders specialists who fear it’s going to trigger an increase on this drawback. Different specialists concern it may cause depression or suicidal thoughts. These claims are all fiercely disputed and debated. I felt trapped between two dangerous decisions—ongoing weight problems, or medicine with a number of 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, massive numbers of Japanese employees migrated to Hawaii and so they have now been residing on the island for 4 generations. They’re genetically similar to the Japanese individuals who didn’t go away. It seems that after 100 or so years, Japanese Hawaiians are actually nearly as obese because the individuals they dwell amongst. Some 18.1% of them are overweight, in comparison with 24.5% of Hawaiians general. Which means Japanese Hawaiians are 4 instances extra prone to be overweight than individuals again in Japan. So one thing apart 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 cook dinner a meal for me with a few of his trainees, and to clarify the rules behind it. He advised me: “The Japanese delicacies’s [core] characteristic is simplicity. For us, the easier, the higher.”
He started to make a typical Japanese meal, the type individuals have 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 rather a lot. We’re an island nation. We admire fish.” Because the mackerel was grilled, I watched as varied oils and fat leeched out. Much more importantly, Masaru defined, this was an illustration of one of many essential rules of Japanese cooking. Western cooking, he stated, is primarily about “including.” To make meals tasty, you add butter, lemon, herbs, sauces, all kinds of chemical compounds. “However the Japanese fashion 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 rules of consuming. The very first thing I needed to study was “triangle consuming.” All my life, after I was consuming a meal with totally different parts, I’d largely 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 approach of consuming.” A meal like this ought to be eaten in a triangle form. “First, drink the soup slightly bit, then go to the facet dish—one chew. Then strive the rice, for one chew. 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 … Preserving 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 to 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 individuals have constructed up a very totally different relationship to meals over 1000’s 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 just lately—in residing reminiscence, in reality. Barak Kushner, who’s professor of East Asian Historical past on the College of Cambridge, advised the author Bee Wilson, for her ebook First Bite, that till the Nineteen Twenties, Japanese cooking was simply “not excellent.” Recent fish was eaten solely as soon as per week, the food 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 elements of Asia {that a} new food culture started to be invented, fairly consciously, to provide more healthy troopers. After the defeat of Japan within the Second World Conflict, when the nation was in ruins, the brand new democratic authorities stepped up this transformation.
To search out out how Japan created a radically totally different meals tradition, I arrived at Koenji Gakuen Faculty with my translator on a stiflingly scorching September morning. It’s a typical college for teenagers aged from 5 to 18 in a middle-class neighborhood in Tokyo. We have 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, youngsters waved at her affectionately, and shouted her identify, desirous to know what they have been having for lunch that day. By regulation, Harumi stated, each Japanese college has to make use of knowledgeable like her. It took her three years to qualify, on prime of her educating diploma, and he or she defined that on this place, you may have a number of necessary roles to play. You design the varsity 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 coach the kids about diet. Then you definitely educate their dad and mom on the identical subject.

Harumi advised me that at the moment’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 youngsters 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 diet … Generally with frozen meals, they use a number of synthetic components.”
As soon as the meal was prepared, Harumi carried a tray over to the workplace of the varsity’s head, Minoru Tanaka. It’s a authorized requirement that the principal of every college ensures lunches meet dietary tips. It’s additionally customary for principals to have the identical lunch as the youngsters and to eat it first, to verify it’s secure, nutritious, and scrumptious. He rolled up his sleeves and dug in. After a second, he nodded approvingly. Earlier than they started to eat, a toddler stood on the entrance of the category and skim out what at the moment’s meal was, which a part of Japan it got here from, and the way the totally different components are good to your well being. She then stated “Meshiagare!,” the Japanese equal of “bon appétit,” and everybody applauded.
Whereas the youngsters have been consuming, Harumi held up some coloured ropes. Each represented a special type of meals you must be wholesome. On today, she held up the yellow rope, representing carbs, and requested what they do to your well being. A toddler yelled: “Provide you with power!” She held up the purple rope, representing calcium, and a toddler yelled that it makes your bones stronger. As she went although the meals teams, she tied every rope collectively, to point out that together they make a wholesome meal. “By means of the varsity lunches, we clarify the meals itself,” the principal, Mr. Tanaka, advised me.
As I walked round, I had a nagging sense that there was one thing uncommon about this place. However it was solely after a number of hours that I noticed what it was. There have been no obese youngsters. None. My translator and I walked from class to class, asking the youngsters what they most appreciated to eat. The primary little one I spoke to, a 10-year outdated lady, stated: “I like inexperienced greens, like broccoli.” One 11-year old-boy advised me he loves rice as a result of “the rice has protein. For those who eat balanced meals each meal, then you may have a really robust 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 individuals I mentioned this with have been puzzled to see that I used to be puzzled. We educate youngsters to take pleasure in wholesome meals, they defined. Don’t you?
Up till this level, I had seen points of Japan’s method towards well being that appeared completely admirable. However subsequent, I noticed one thing that left me with combined emotions. In 2008, the Japanese authorities seen that weight problems was barely rising. So that they launched the “Metabo Law,” which was designed to cut back the unfavourable penalties of a big waistline. The regulation contained a easy rule. Every year, each office and native authorities in Japan has to herald 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 individual is referred to counseling, and workplaces draw up well being plans with staff to drop some weight. 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 follow. An organization referred to 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 numerous methods, and Tanita is on the most enthusiastic edge.
The primary individual I met with was Junya Nagasawa, the corporate’s boss. He’s a good-looking 57-year-old who persistently comes prime of the corporate’s strolling league desk, with almost 20,000 steps a day. When the Metabo Legislation got here into power, he advised me, there was a sudden demand from firms for applied sciences that would 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 whenever you arrive at work day by day, it tells you ways a lot you’ve walked—and the way a lot your colleagues have walked. You’re inspired to submit photographs of all of your meals, and pledges for a way you’ll enhance your well being—that are, once more, seen to your complete firm.
Nagasawa advised me these measures meant he began to stroll rather more. “It’s not troublesome to stroll, nevertheless it’s very troublesome 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 advised me he got here to work right here straight from college, and he had by no means carried out 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 acutely aware of the looming annual well being checks. So he made some modifications. Earlier than, “after I was watching TV, I’d normally eat junk meals or snacks.” He minimize them out fully. And “after I exit to different locations, I strive to not use trains or drive, however stroll.” Figuring out he’ll be accountable helps him, he stated. I heard this repeatedly from the employees.
I advised all of the Japanese individuals I talked to that in case you tried this within the U.S. or Britain, individuals could be outraged and burn down their places of work. They invariably regarded puzzled, and requested me why. I stated that folks 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 is just not 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 impression. Its weight problems price 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 dwell within the Japanese fashion. Each morning round 7 or 8 a.m., in parks throughout Japan, aged individuals collect in teams and train collectively. You’ll be able to watch individuals of their 80s and 90s dancing or doing yoga. Japanese individuals dwell longer than anybody else on earth. On common, males dwell to be 81, and girls reach 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 population on this planet (although another village in Japan has just lately 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 individuals there are aged 90 or older. The individuals who dwell right here have had exhausting lives—they have been largely poor farmers, and through the Second World Conflict, 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 middle, a number of the very aged residents have been arriving, trying ahead to catching up with one another, taking part in video games and exercising collectively. The primary individual we met was Matsu Fukuchi, a 102-year-old girl, who had walked to the middle from her residence, slowly however with out a stoop, holding on to a cane. Her eyes watched us with curiosity. She stated she took a number of pleasure in life. “I get along with my grandchildren and have enjoyable, and dance. I really like to bop.”
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 bop. She moved her hips gently in time with the music, and the opposite ladies matched her rhythm, waving their arms. She regarded towards me, beaming.
As I watched these centenarian ladies transfer with the music, I noticed—this is what this complete 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 remedy the weight problems disaster. Extra life. Extra well being. Extra years of pleasure.
Immediately, 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 dwell. It ought to be doable, subsequently, 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 thought of one thing from my very own childhood. If I may take a teenager again to the Britain or the U.S. of the Eighties, they might be astonished by one behavior. Individuals smoked cigarettes in all places. They smoked in eating places. They smoked on planes. They smoked on recreation reveals. Whenever you went to see the physician, he would smoke whereas he examined you. (I’m not kidding: I bear in mind this occurring.) For those who had stated to individuals then that inside a technology, smoking would come to appear to be a factor of the previous, we might not have believed you. In 1982, for instance, 33% of men and women within the Minnesota Coronary heart Survey have been people who smoke. At this time, 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 into just like the Japanese. “I hope so,” he stated. “I positively assume so,” he clarified. I’ve traveled to many alternative elements of the world the place they’ve begun modifications that convey us nearer to Japanese ranges of well being. In Mexico, they introduced a sugary-drinks tax. In Amsterdam, they restricted sugary drinks from colleges and gave obese youngsters customized well being coaches, slashing childhood obesity by 12% between 2012 and 2018 (although it has ticked up since). In varied U.S. cities, there are “food is medicine” applications. There are dozens of social modifications we may make that would scale back the massive forces driving up weight problems.
None of this, within the quick 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 international locations (except for Japan), many people should weigh the dangers of constant to be obese, towards the dangers of taking these medicine. I’m persevering with to take Wegovy, however with a heavy sense of concern in regards to the potential risks. But Japan reveals us that if we make the proper social modifications now, we are able to free our youngsters of this dilemma. If we glance East, we’ll notice we don’t need to be trapped within the alternative between Wegovy versus weight acquire without end.
