Page xv/Page 7 – I need to tell you about Hannah: I have changed Hannah’s name and a few minor identifying details here, to respect her and her family’s privacy. Because I am describing her from memory, I showed everything I wrote about her to another of her closest friends, Bronwen Carr. She confirmed that this matched her recollections. I also discussed this section with lots of other people who knew Hannah, who agreed that this is, to the best of our knowledge, an accurate picture of her.
Page xv/Page 7 – I sat down to watch a play called Atlantica: My description of Atlantica here is entirely from memory. I tried really hard to locate a text of the play but it seemed to have vanished. Since I’m recalling it from a distance of nearly twenty-five years, I’m sure I’m getting some details wrong, and the dialogue will not be exactly as it appeared in the script. I tracked down everyone I knew who had seen it and asked if this description matched their recollections. They said that broadly it did, though recollections differed a bit from person to person, as you’d expect after all this time. Some of them said that I am wrong to remember that only Hannah and I thought it was absurd, and in fact, a lot of the audience felt the same way. But by contrast, one of the cast members said that it was a more serious play than I remembered, and that lots of people took it seriously.
It’s possible we are all remembering it accurately. There were three performances of the play at the festival, and it looks like people at each reacted differently. One critic writing at the time noted that audiences reacted in contrasting ways, writing: ‘So that, for instance, Atlantica, a new save-the- whale play from Cambridge which blended B-movie and SF elements with an undertow of seriousness reminiscent of the TV series Edge Of Darkness, could play to three audiences giving radically different responses from silent seriousness to howls of campy laughter, and accept that each response was both legitimate and respectful on its own terms.’ See https://www.cix.co.uk/~shutters/reviews/01091.htm as accessed 20th February 2024.
Page xvii/Page 9 – Socrates whale, slugging hemlock: When I reflected on this memory, I had a recollection that in the festival’s newsletter, Noises Off, somebody published some sketches of suicidal whales based on famous people. I am not sure if Hannah told the person who drew these sketches this joke, and it was based on what she said; or if Hannah heard this joke from the person who drew them, and she then told it to me. If anyone knows the name of the person who drew them, please let me know, and I’ll credit him or her in future editions of the book!
Page xviii/Page 10 – I knew I shouldn’t have taken that paper bag off my head: I saw Joan Rivers live lots of times and heard versions on this line several times.

Page xxi/Page 14 – Then one night, she began to choke while eating: When I later ordered Hannah’s death certificate, it said she had suffered cardiorespiratory arrest triggered by choking, and listed Type II diabetes and thymoma (a disease where cancer cells form in the thymus, which is in your chest) as additional factors.

Page xxiii/Page 16 – the most blubbery mammal: Blue whales have around 35 per cent body fat generally but can get up as high as 50 per cent in good times. Grizzly bears, polar bears and elephant seals can also all tip over 40 per cent in good times. See https://a-z-animals.com/blog/fattest-animals/, as accessed 9 November 2023. Note that if I were a forty-four-year-old woman, I’d actually have been within the ‘Ideal’ range with 32 per cent body fat, according to research published in the American Journal of Clinical Nutrition. As a forty-four-year-old man, however, I was firmly in the ‘Obese’ category. See D. Gallagher et al., ‘Health percentage body fat ranges: an approach for developing guidelines based on body mass index’, American Journal of Clinical Nutrition (2000), 72, pp. 694–701.
Page xxiii/Page 16 – My grandfather died of a heart attack when he was the age I am now, forty- four: My mother and grandmother found his death almost impossible to talk about. Throughout my childhood and all the way into my twenties, I had mistakenly believed he had died in an industrial accident. It was only when I spoke with one of my uncles while researching this book that I learned the full facts of his death.

Page xxvii/Page 20 – I want make you aware, right at the start, of a few caveats: Here’s another caveat. Because of social media, there is a constant threat that any group of people, anywhere in the world, can subject you to a reputational punishment-beating for disagreeing with them. As a result, a lot of people are frightened to think out loud or explore difficult subjects in writing. You’ll notice that the tone of a lot of books is becoming cringingly apologetic or bitterly sarcastic, as an attempt to ward off this danger. I am determined not to do this. You can’t have an adult conversation if you enter it in a defensive crouch. I am going into this with an open mind and an open heart, and I am assuming good-faith readers who want to come on the journey in the same spirit. It’s difficult to stay open-minded on such a sensitive subject, I know: our relationships with our bodies are so fraught with anxiety and shame that at times, writing this book felt like stomping into a field full of landmines in a pair of oversized boots. But I believe that if you tune out the hysteria online, it is still possible in our culture to follow the facts, in a spirit of rationality and love. Indeed, people are hungry for it.

Page 8/Page 31 – what happens if the effects of GLP-1 can be made to last: Another totally unexpected breakthrough made scientists realise why they should be doing this urgently.
One of John’s colleagues at the Hammersmith Hospital was an ambitious young medical doctor and PhD student from Durban, South Africa named Carel Le Roux, who arrived there in the year 2000. When he had grown up under Apartheid, there had been almost no obese people, and he was fascinated by it as a medical problem. He became particularly intrigued by a form of medical intervention that was, at that time, rare in Britain, and almost unknown in South Africa: bariatric surgery. This is where severely obese people whose health is in peril are given extensive internal surgery, some of their internal organs are rearranged and reconnected, and afterwards, they find it very hard to continue to eat in large quantities. As a result, most people who undergo the surgery lose enormous amounts of weight.
Looking at the research on this procedure, Carel wondered about one thing in particular. It is not totally clear why bariatric surgery works so effectively. Their stomachs are smaller after the operation – but your stomach has an extraordinary capacity to expand again. Somehow, though, most people who go through the surgery remain far below their previous weight levels. He began to have a hunch that it could be related to this new research on gut hormones. He knew that if you inject GLP-1 agonists into people, their appetites change, and they want to eat less. So Carel asked: could it be possiblethat after this surgery, your gut hormones also change? Might that be one of the reasons why it works so well?
He began to try to snuffle out the answer. He got bariatric surgery patients to come into the hospital not long after their operations, and gave each of them a small pot of ice cream to stimulate their GLP-1 production. Then he took samples of their blood, at timed intervals – one as soon as they had the ice cream, then another an hour later, then another two hours later. For a whole week, he worked flat-out for fourteen-hour days to process these samples, and at 7 p.m. on a Friday night, he finally got the results from the tests he had taken as the patients were eating the ice cream. He felt crushed. There was no difference between the gut hormones of those post-bariatric surgery patients and the rest of us. Nothing. He thought, ‘Well, that was a waste of a week of my life’. He went home, had a barbecue and drowned his sorrows in red wine.
On Monday morning, he went back to work, and with low spirits, he processed the remaining blood samples that had been taken at regular intervals after they’d eaten the ice cream, expecting to find more results that revealed nothing had changed. What he discovered shocked him.
In the samples taken two hours after eating the ice cream, the bariatric surgery patients’ GLP-1 levels had massively soared – to three times higher than in people who haven’t had the surgery.
It seemed that something was happening after surgery that meant these patients were flooded with GLP-1 at precisely the point at which they would previously have felt hungry again. It was this surge in GLP-1 that was dramatically reducing their appetites. Now, for Carel, it all fell into place: GLP-1 is one of the gut hormones that sends a signal to stop eating, and after surgery, ‘the gut is talking much louder to the brain, in a voice the brain can understand. The signal is now three times higher.’
Unlike in the previous experiments, where people were injected with GLP-1 agonists and only felt more full for a few minutes, it turned out that for these bariatric surgery patients, the effect had lasted. Indeed, higher levels of this hormone seemed to be one of the keys to their dramatic weight loss.
He had a hunch about why. When you have this surgery, your small intestine is moved to a different place, and it has GLP-1 receptors on top of it. So it seems that for these patients, when they eat, those receptors get hit by food later, and for longer. As a result, they are less hungry. It’s a key reason, he believes, why the surgery succeeds even though your stomach can expand afterwards.
‘It was a eureka moment,’ Carel told me. In science, with any change you want to produce – losing weight, for example – you are always searching for the mechanism that explains how that change can take place. ‘We were able to provide a mechanism. That was the crucial thing. Once we understand the mechanism, we come closer to the truth. We suddenly had insight into a mechanism we didn’t have before.’ The mechanism was GLP-1 itself.
To test their theory further, the team did more research. They gave patients who’d had bariatric surgery a drug that blocked GLP-1 from kicking in when they ate. Suddenly, they started stuffing their faces again, almost as if they’d never had the operation at all. ‘It was as if you switched off my bypass,’ the patients said. It really did seem that GLP-1 is a major brake on human appetite, and if you can boost its levels over the longer term, you produce dramatic weight loss.
In the wake of Carel’s discovery, a lot more scientists swung back to investigating GLP-1. They began to suspect that if you could give people a GLP-1 agonist – a copy of the real gut hormone – and you could make it last, then you could give them, in effect, a chemical form of bariatric surgery, with all the benefits, and without the quite serious risks. So Carel began to ask: ‘How can we create a bypass without using an operation?’
See C. M. Borg et al., ‘Progressive rise in gut hormone levels after Roux- en-Y gastric bypass suggests gut adaptation and explains altered satiety’, British Journal of Surgery (2006), 93(2), pp. 210–15, doi:10.1002/bjs.5227. the official results of their major trial giving semaglutide to obese people: J. P. H. Wilding et al., ‘Once-Weekly Semaglutide in Adults with Overweight or Obesity’, New England Journal of Medicine (2021), 384(11), pp. 989–1,002, doi:10.1056/NEJMoa2032183. compared to just 2.4 per cent who had been given a placebo: In the trial, some were given the real drug, and some were given the placebo. In that first trial, everyone – in both groups – was also given a lifestyle intervention. Both groups lost weight, but the people on the drug lost more. The placebo- subtracted weight loss of people given the drug was 12.5 per cent. See ibid. after they quit, most people regain two-thirds of the weight they have lost within a year: https://dom-pubs.onlinelibrary.wiley.com/doi/10.1111/dom.14725.

Page 16/Page 39 – For between 5 and 10 per cent of people who take these drugs: W. T. Garvey et al., ‘Two-year effects of semaglutide in adults with overweight or obesity: the STEP 5 trial’, Nature Medicine (2022), 28, pp. 2,083–91, https://doi.org/10.1038/s41 591-022-02026-4. It’s not absolutely certain that it’s the side effects that are the sole cause of patients not continuing with the drug. STEP 5, for example, had a 92.8 per cent completion rate, but that’s averaged across the placebo and semaglutide groups. And in some of the adolescent studies it’s almost the exact same drop-out rate for placebo as for the real drug, so more is at work here than side effects.
Page 17/Page 40 – Similarly, you burp because: There are some other theories about why people burp on these drugs. You can read a good summary of them here: https://www.theatlantic.com/health/archive/2023/05/ozempic-burping-smell-eggs-side-effect/673925/, as accessed 10 October 2023.

Curiously, a significant percentage of the people who use the first versions of these weight loss drugs face a different problem. They take them and learn to tolerate the side effects – but they don’t lose weight. For some unknown reason, the effects don’t kick in. In one trial of semaglutide, for example, 77 per cent of the people taking part lost 5 per cent or more of their body weight, and more than half lost 15 per cent – but there were quite a large number who didn’t lose any weight at all: 23 per cent. A small number even gained weight on the drug. Nobody knows why these disparities are happening. This doesn’t seem to be a problem with the next generation of the drugs though: in a trial of the ‘Triple G’ drug that boosts three different gut hormones, literally everyone on the trial taking the higher dose lost 5 per cent of their body weight or more. See Jastreboff et al., ‘Triple-Hormone-Receptor Agonist Retatrutide for Obesity’.

This study found that BMI began to increase at this time, which is why I say it was ‘likely’ that obesity rose at this time. BMI and obesity are not synonymous, but they are often closely matched – see the explanation from Walter Willett in Chapter 11.

Page 32/Page 55 – It’s healthy. It’s balanced: There is a sense in which it is like the diet my dad grew up eating, and a sense in which it isn’t. It is like his diet because it is nutritionally balanced and not particularly high in sugars, fats or artificial sweeteners. It is 23 per cent protein. In another sense, it is not like the diet my dad grew up eating: it is created in a factory and consists of more than twenty ingredients.
Page 32/Page 56 – Then he introduced the rats to the hyper-American diet: In addition, there was a control group who continued to only get the standard rat chow. In order to measure their dopamine levels, all the rats I describe here had electrodes inserted into their brains. In the experiment, some other rats were injected with viruses that changed their DNA, to see if that affected the way they respond to dopamine. Those rats are not the ones I am describing here. Both groups also, at the same time, had access to as much of the healthy rat chow as they wanted: There was a third group, who acted as the control group.
Page 32/Page 56 – You might call these cages Cheesecake Park: I have nicknamed this experiment ‘Cheesecake Park’ in a cheeky tribute to a famous experiment named ‘Rat Park’, which I wrote about in my previous book Chasing the Scream: The Search for the Truth About Addiction (Bloomsbury, 2019).
To explain Cheesecake Park a little more, I’d like to recap a bit about the Rat Park experiment, drawing on what I said in my TED Talk, ‘Everything You Think You Know About Addiction Is Wrong’. If you had asked me, when I started researching this topic thirteen years ago, ‘what causes heroin addiction?’, I would have looked at you as if you were a bit stupid, and said – obviously, heroin causes heroin addiction. The clue is in the name. We think that if I kidnapped the next twenty people to walk past your home, and I injected them all with heroin every day for a month – like a villain in a horror movie – they would all become addicted to heroin, for a simple reason: there are chemical hooks in heroin that their bodies would start to desperately physically crave, and at the end of that month, they’d have a tremendous physical hunger for the drug, and that’s what addiction is. Indeed, that’s why another word for being addicted is being ‘hooked’.
It turns out that chemical hooks are real – but they are only one part of a much bigger picture. Here’s how I explained one aspect of this in Chasing the Scream:
A famous advertisement that ran on US TV in the 1980s, paid for by the Partnership for a Drug-Free America, explained it best. It shows a rat in close-up licking at a water bottle, as the narrator says: ‘Only one drug is so addictive, nine out of ten laboratory rats will use it. And use it. And use it. Until dead. It’s called cocaine. And it can do the same thing to you.’ The rat runs about manically, then – as promised by the scary music – drops dead. Similar rat experiments had been run, to prove the addictiveness of heroin and other drugs.
But when [the Canadian scientist] Bruce [Alexander] looked at these experiments, he noticed something. These rats had been put in an empty cage. They were all alone, with no toys, and no activities, and no friends. There was nothing for them to do but to take the drug.
What, he wondered, if the experiment was run differently? With a few of his colleagues, he built two sets of homes for laboratory rats. In the first home, they lived as they had in the original experiments, in solitary confinement, isolated except for their fix. But then he built a second home: a paradise for rats. Within its plywood walls, it contained everything a rat could want – there were wheels and coloured balls and the best food, and other rats to hang out with and have sex with.
He called it Rat Park. In these experiments, both sets of rats had access to a pair of drinking bottles. The first bottle contained only water. The other bottle contained morphine – an opiate that rats process in a similar way to humans and that behaves just like heroin when it enters their brains. At the end of each day, Bruce or a member of his team would weigh the bottles to see how much the rats had chosen to take opiates, and how much they had chosen to stay sober.
What they discovered was startling. It turned out that the rats in isolated cages used up to 25 milligrams of morphine a day, as in the earlier experiments. But the rats in the happy cages used hardly any morphine at all – less than 5 milligrams. ‘These guys [in Rat Park] have a complete total twenty- four-hour supply’ of morphine, Bruce said, ‘and they don’t use it. They don’t kill themselves. They choose to spend their lives doing other things.’ This led me to conclude that the opposite of addiction is connection.
As I wrote about Cheesecake Park, I began to wonder about the relationship between these two experiments.
Rat Park is an experiment that demonstrates that the environment plays a crucial role in addiction – a stronger one, in fact, than the inherently ‘hooking’ effects of the drugs.
But for a while, I wondered if this was contradicted by Cheesecake Park. It is an experiment in which the rats are not alone – they have plenty of friends to scamper around with and have sex with – yet they still gorge on the cheesecake.
How can these experiments be reconciled? I thought about this and discussed it with experts.
As I explain later in this book, both addiction and obesity can be explained by something called the ‘bio-psycho-social model’. This means there are three kinds of causes of these problems: biological (things like your genes, or brain changes), psychological (for example, trauma, or how you think of yourself) and social (for example, loneliness, or poverty). They all play out to some degree in any individual with these problems, though the exact ratios will vary from person to person, and from condition to condition.
Human circumstances are always complex and it’s hard to disentangle the different facts that drive us to behave the way we do, but one of the good things about rat experiments is that you can manipulate the lives of rats to simplify the factors affecting their behaviour down to a few variables. In Rat Park, you can make them isolated, and see how it affects them. In Cheesecake Park, you can expose them to food comprised of sugar and fat, and see how that affects them.
When you see it through the prism of the bio-psycho-social model, the relationship between the two experiments becomes clearer. Rat Park varies the social component of the problem, to see how much effect it has. Cheesecake Park varies the biological component of the problem, to see how much effect that has. They are both real, and out here in the complex messy human world, they both play out in our lives. Rat Park shows us that isolation supercharges loneliness. Cheesecake Park shows us that cheesecake and other processed foods override our sense of satiety and make us massively overeat.
I would love for a group of scientists to take this further, and test what happens when the social and biological components combine. You could take a group of rats and split them into two. The first group could be given access to cheesecake, but also have friends and a stimulating environment. The second group could have cheesecake, but no friends or stimulation. We know from Cheesecake Park that they would both eat a lot of cheesecake and gain a lot of weight – but Rat Park makes me suspect the second group would go even further and overeat to an even greater degree. It would be fascinating to see the interaction of the environmental and biological components in this context.
Page 33/Page 57 – He was struck by how quickly they flipped for the new food: Paul also says in the paper: ‘Consistent with previous reports, there was a tendency for consumption of the cafeteria diet to decrease over time in the extended access rats. This may reflect the development of tolerance to the palatability of the food items provided as part of the cafeteria diet over time. Nevertheless, the preference for the cafeteria diet versus standard chow remained consistently high throughout the experiment.’
Page 34/Page 57 – They basically starved, rather than eat this other food: In the write-up of the experiment, he explains, ‘extended access rats obtained only a small fraction (~5%) of their total caloric intake from chow (FIG. 2B), and consumed the cafeteria diet almost exclusively.’

Page 46/Page 70 – likely to be responsible for much of our obesity epidemic: Ibid., p. 19. There is a potential eighth factor at work here too.
The eighth factor is that these foods promote what John Blundell, a Professor of Psychobiology at Leeds University, calls ‘passive over-consumption’.
When I was a child, a small soda from McDonald’s and Burger King was 8 ounces, and a large drink was 16 ounces. Now, a small drink is 12 ounces, and a large drink is 32 ounces – double the size, and double the calories. You used to get a cup of Coke. Now you get a bucket of it. Michael Lowe, a Professor
of Clinical Psychology at Drexel University, explained to me how this undermines satiety over time: ‘In the 1970s, a bagel was this size, and cookies were about this size.’ He made circles with his hands that looked pitifully small. ‘Over the decades, the cookie and the bagel and many things got progressively bigger and bigger. Humans have a tendency to eat what’s put in front of them, and they assume – “oh, a cookie? I can eat a cookie. As a matter of fact, I can eat two cookies, because in the seventies, that’s what I ate.” Well, two cookies back then was maybe 300 calories. Now it’s 700 calories or more.’
He leaned forward. ‘We didn’t change. The food changed.’
At the same time, not only did the portions get bigger, but they were redesigned so they become more dense in calories. Compare a potato you dug out of the ground to a potato chip. In the process of being transformed in a factory, the potato has been stripped of the vast majority of its water, making it drier, crunchier and far more dense with calories per mouthful than the original. This process – of cramming more calories into the same mouthful of food – is happening with a lot of what we eat, often without changing its external appearance at all.
So ‘the dish is now 800 calories, rather than 550. But you’re ordering the same thing.’ It seems fine: I had it then, why not have it now? But then ‘people start to notice: I’m looking a little pudgy in the face. My pants [i.e. trousers] are feeling a little tight around the waist. I haven’t been doing anything different. What is happening is passive over-consumption – the calories are slipped in under the radar.’
As we eat these larger, more calorie-dense portions that look the same to us, our stomachs expand, and over time, we need more food to be satiated.
Page 46/Page 70 – processed foods make you eat, on average, 500 calories more every day: K. Hall et al., ‘Ultra-Processed Diets Cause Excess Calorie Intake and Weight Gain: An Inpatient Randomized Controlled Trial of Ad Libitum Food Intake’, Cell Metabolism (2019), 30(1), pp. 66–77, https://www.cell.com/cell-metabolism/fulltext/S1550-4131(19)30248-7.
Page 47/Page 71 – making many of the animals they own as big and bulky as possible: This varies a little by species. With pigs, we mostly eat their muscles (that’s the pink bit of your bacon), so they have in fact been selectively bred to be less fat and more muscular. But the factory-rearing system means that most animals – including chickens, turkeys and cows – are much fatter.

Page 69/Page 94 – could this turn around the lives of people like them?: Behind the statistics about the improvements in health caused by dramatically reversing obesity, there were a lot of human stories. I wanted to know: what does it feel like to come back from severe obesity? I had already spoken to Jeff Parker, who took Mounjaro for six months. Now I wanted to see what – in an optimistic scenario, where the drugs keep working without significant drawbacks – the effects might be on an obese person’s daily quality of life.
Brandon Youngblood is a professor of psychology at Sacramento City College in California. He explained to me that growing up in Stockton, California, ‘I was always a big kid. My family is an obese family. So I struggled with my weight my whole life.’ By the time he went to high school, he was rising through the 200-pound range, and by the time he got to college, ‘I ballooned into the 300s.’ Every year or so, he would lose some weight by dieting, but then he would regain it, plus some. ‘I never had a stable weight in my life,’ he said, and by the time he was in his thirties, he hit 506 pounds. He felt like a prisoner in his own body. ‘It was just like being trapped. Miserable. Hot all the time. Sweaty all the time … Your joints, your chest, your feet, your body would just be experiencing pain and tension soreness … I was just completely overwhelmed and uncomfortable constantly.’ The pain was so bad that ‘I wouldn’t want to do anything … I would sleep a lot. It would be very difficult for me to get up in the morning because you were just physically tired, but also because of severe sleep apnea, just not getting oxygen to your brain. And then you’d be fatigued easily.’ When you don’t get restful sleep, ‘nothing else functions to the degree that you’d like it to. Your cognitive abilities become reduced and you just get cranky and ornery.’ All the time, he felt ‘you’re just at the mercy of your body, and you’re not able to function’.
In an uncountable number of ways, he said, ‘you can’t live your life when you’re nearly 500 pound’. For example, he ‘wanted to be able to be a better partner intimately with my then-girlfriend. It was very difficult, as you might imagine, to be a good lover when you’re not able to feel good in your body, but also just perform. Being that heavy makes it very difficult to be sexually competent.’ He felt he was ‘in a body that was not functioning for me’, and it made him sullen, cranky and miserable.
He was thirty-one years old when he had bariatric surgery, and he lost more than 250 pounds in the first year. ‘I remember one of the first things my girlfriend at the time, now my wife, Mallory, and I did, right after the
surgery, was go down to Santa Monica, and we just walked the pier. It was not something I ever would have done. I couldn’t park the car, walk to the pier, walk the pier and then go back. Those were just things I couldn’t do. Now I don’t have to worry about that. I just walk like normal people would walk.’ As he looked out over the Pacific Ocean, he knew he had been on the path to diabetes and a much higher likelihood of hypertension, cancer, dementia, stroke. Now all that was receding like the tide.
‘I think I’m a happier, more joyous person now,’ he said. ‘I feel great. It was just a huge change in perspective. Just not as tired and sore all the time. Your mind is more clear. You almost feel like a new person.’ Now, ‘I’m not at the mercy of physical limitations.’ His career was transformed: with all the new energy he had, he became a successful professor. His marriage was transformed: sexually and emotionally, he was able to be present with his wife in a way that was impossible when he was so exhausted and unwell all the time.
He said that if he hadn’t been able to change in this way, ‘I would probably have just remained very miserable. I probably wouldn’t have been able to progress in my career. I would probably still be living with my folks …
I wouldn’t be able to live a life at all. It was just like becoming such a burden that I wasn’t able to kind of move forward … I think that my relationship with my wife would have ended.’ He said he is strongly opposed to stigma – he can remember the sting of cruel comments – and argued that we should do everything we can to dismantle it. ‘I strongly support body positivity,’ he added. Then he said carefully: ‘The wrong people take the stance that I’m about to take, and I don’t want to be associated with them by any means. But being 500 pounds is not healthy. We shouldn’t be 500 pounds.’
It nearly destroyed him, he believes, and we need to tell the truth about that. There are also certainly some serious negative effects to the surgery. He has something called ‘dumping syndrome’, where food passes quickly and painfully through you, and you sometimes need a toilet urgently.
Indeed, those significant downsides to the surgery are a reason why, for other people, he’s so excited about the new weight loss drugs, which seem – if the early signs are right – to provide all the benefits he’s experienced, without the extreme step of having major surgery. ‘I think if I could have had the same results and be at the same place with medication as opposed to intervention, I would strongly consider that. If I could guarantee the same trajectory, of course – I would love to not be a prisoner to the bathroom. Right? That would be something that would be wonderful. I would choose that in a heartbeat.’
Brandon looked back over all the years he was physically stifled and sickened by his obesity, how his health recovered when it was treated – and how his life then changed in incalculable ways when it was cured. This was far beyond vanity. His health was transformed. He looked a little ruminative and emotional. ‘It’s hard for me to imagine. My whole life I wanted a pill that would help me with this problem.’ He wondered: if now we have it, and it can reverse the huge health risks of obesity, why would we turn it down?

Novo Nordisk – who make Ozempic and Wegovy – sent a detailed response, which you can read in full in the extended endnotes: I put the following questions to Novo Nordisk:
Dear Novo Nordisk media team,
I am a British journalist who has written a book which is being published by Bloomsbury Publishing in the UK and Crown Publishing in the US about the new weight loss drugs and their implications. There is information about me at www.johannhari.com. It is a balanced book investigating both the significant health advantages of these drugs (which I myself am taking, and benefitting from) and the potential risks. I am looking at this matter from a personal, human and scientific perspective.
I am writing to you to give you the right of reply and an opportunity to comment on the potential risks/drawbacks of these drugs that I will be raising in the book in respect of GLP-1 agonists.
Please could you respond with any comments on the below statements by Tuesday November 21st:
1. If a user stops taking Ozempic, Wegovy or other GLP-1 agonists, the user on average regains two-thirds of the weight they lost when on GLP-1 agonists within twelve months as shown for example in this study:
Wilding, JPH, Batterham, RL, Davies, M, et al. Weight regain and cardiometabolic effects after withdrawal of semaglutide: The STEP 1 trial extension. Diabetes Obes Metab. 2022; 24(8): 1553-1564. doi:10.1111/ dom.14725
2. The longer term risks to health from Ozempic, Wegovy or other GLP-1 agonists are not known and so there could be serious negative health effects for some users. For example, anti-psychotics were first developed in the 1950s, but the fact they cause dementia only became clear 50 years later: Jonas, K., Abi-Dargham, A., & Kotov, R. (2021). Two hypotheses on the high incidence of dementia in psychotic disorders. JAMA Psychiatry. Published online September 15, 2021. doi:10.1001/jamapsychiatry.2021.2584 (Link).
I am not suggesting GLP-1 agonists cause dementia – only that they may have presently unknown long-term effects.
3. One longer term effect of Ozempic, Wegovy or other GLP-1 agonists could be damage to children in the womb, where the mother has taken GLP-1 agonists during pregnancy, such that their brain development could be negatively impaired and could lead to increased risk of impaired reward responses, impulsivity, attentional issues, autism or predisposition to substance abuse:
Warning labels on these drugs advise women not to take them whilst pregnant – “may harm your unborn baby”, “may cause foetal harm”. Animal studies have indicated there may be risks to neonatal development, and no good human studies exist:
See: https://www.ozempic.com; https://www.wegovy.com/taking-wegovy/how-to-use-the-wegovy-pen.html; https://www.accessdata.fda.gov/drugsatfda_docs/label/2022/215866s000lbl.pdf
For more detailed information see: https://www.drugwatch.com/news/2023/09/07/fda-warning-pregnancy-wegovy-ozempic/amp/
“Studies in pregnant rats have shown embryofoetal mortality, structural abnormalities, and alterations to growth when administered during organogenesis at maternal exposures below the maximum recommended human dose (MRHD). Early pregnancy losses and structural abnormalities were observed in rabbits at doses below the MRHD. In cynomolgus monkeys, early pregnancy losses and structural abnormalities were observed at exposures of 10-fold or higher that of the MRHD. In rabbits and monkeys, these finding coincided with marked maternal body weight loss. Salcaprozate sodium (SNAC), an absorption enhancer in the oral tablet has been shown to cross the placenta and reach fetal tissue in rats. Administration of SNAC to pregnant rats has shown an increase in number of stillbirths and a decrease in pup viability. There are no adequate and well-controlled studies in pregnant women.” From https://www.drugs.com/pregnancy/semaglutide.html
These concerns about neonatal development in humans were raised with me by reputable scientists in the field.
4. Ozempic, Wegovy or other GLP-1 agonists increase the risk of contracting thyroid cancer. For instance, French scientists found that GLP-1 agonists increase an individual’s risk of thyroid cancer by 58 percent from what it would have been had they not taken the drug: https://diabetesjournals.org/care/article-abstract/46/2/384/147888/GLP-1-Receptor-Agonists-and-the-Risk-of-Thyroid?redirectedFrom=fulltext.
Julien Bezin, Amandine Gouverneur, Marine Pénichon, Clément Mathieu, Renaud Garrel, Dominique Hillaire-Buys, Antoine Pariente, Jean-Luc Faillie; GLP-1 Receptor Agonists and the Risk of Thyroid Cancer. Diabetes Care 1 February 2023; 46 (2): 384–390. https://doi.org/10.2337/dc22-1148; https://diabetesjournals.org/care/article-abstract/46/2/384/147888/GLP-1- Receptor-Agonists-and-the-Risk-of-Thyroid?redirectedFrom=fulltext
This was a study using statistical methods to estimate any increased risk of thyroid cancer found in diabetics taking GLP-1 receptor agonists between 2006 and 2018. They were matched with “control” diabetics who were
not taking the drugs. The analysis attempted to control for various factors including whether or not patients were taking any other antidiabetes drugs and relative levels of socioeconomic deprivation. After controlling for these they still found substantial increased risks.
The 58% increased risk is the estimate for all thyroid cancers; they found a 78% increased risk of medullary thyroid cancer in particular.
5. Ozempic, Wegovy or other GLP-1 agonists increase the risk of pancreatitis and stomach paralysis and bowel obstruction, which in some cases will result in a user’s organ failure and death. For instance, Canadian scientists found that GLP-1 agonists significantly increase the risks of pancreatitis and stomach paralysis: https://jamanetwork.com/journals/jama/fullarticle/2810542. Sodhi M, Rezaeianzadeh R, Kezouh A, Etminan M. Risk of Gastrointestinal Adverse Events Associated With Glucagon-Like Peptide-1 Receptor Agonists for Weight Loss. JAMA. Published online October 05, 2023. doi:10.1001/jama.2023.19574 https://jamanetwork.com/journals/jama/fullarticle/2810542
6. Those taking Ozempic, Wegovy or other GLP-1 agonists were nine times more likely than those taking a different anti-obesity drug to get pancreatitis, and more than three and a half times more likely to get gastroparesis (stomach paralysis). That’s a 909% increased risk of pancreatitis and a 367% increased risk of gastroparesis.
That, like other forms of weight loss, the loss caused by Ozempic, Wegovy or other GLP-1 agonists can cause a loss of muscle mass and sarcopenia, which can have negative health effects, especially for older people as it can lead to falls and death: This issue is widely discussed in relation to GLP-1 agonists, and pharmaceutical companies are currently investigating ways to mitigate this risk, see: M. Lenharo, “Anti-obesity drugs’ side effects: what we know so far”, Nature 622, 682 (2023), https://www.nature.com/articles/d41586-023-03183-3
There is evidence that a higher BMI may be protective as we age and/or that losing too much weight later in life isn’t necessarily a good thing, in part for this reason. See for example:
Associations of Change in Body Size With All-Cause and Cause-Specific Mortality Among Healthy Older Adults, 2023; “This study suggests that weight loss was associated with an increase in mortality, particularly among men, highlighting the need to monitor and investigate weight loss in older adults.”
Body mass index and all-cause mortality in older adults: A scoping review of observational studies, 2020; “Overweight BMI classification or a higher BMI value may be protective with regard to all-cause mortality, relative to normal BMI, in older adults. These findings demonstrate the potential need for age-specific BMI cut-points in older adults.”

7. That a small minority of people taking these drugs may experience malnutrition as a result:
This issue is widely discussed in relation to Ozempic, Wegovy or other GLP-1 agonists, see for example: https://www.nytimes.com/2023/04/21/well/eat/ozempic-side-effects-malnutrition.html which includes quotes from Dr. Andrew Kraftson, a clinical associate professor in the division of metabolism, endocrinology and diabetes at Michigan Medicine, who prescribes diets to patients whom he puts on these drugs, hoping to ensure they eat a minimum level of calories.
8. That since these drugs seem to have positive effects on the brain, leading people to want to over-eat less, that there is the possibility that they also have negative effects on the brain, so that use of GLP-1 agonists may in the future be confirmed to cause harm to brain function:
Evidence that the drugs work on the brain’s reward system is extremely strong and well-accepted, see for example: Turton MD, O’Shea D, Gunn I, et al. ‘A role for glucagon-like peptide-1 in the central regulation of feeding’. Nature. 1996;379(6560):69-72. doi:10.1038/379069a0, Jerlhag E. ‘The therapeutic potential of glucagon-like peptide-1 for persons with addictions based on findings from preclinical and clinical studies’. Front Pharmacol. 2023 Mar 30;14:1063033. doi: 10.3389/fphar.2023.1063033.PMID: 37063267; PMCID: PMC10097922.

Front Psychiatry. 2023 Jan 9;13:1092828. doi: 10.3389/ fpsyt.2022.1092828. PMID: 36699502; PMCID: PMC9868418. Aranäs C, Edvardsson CE, Shevchouk OT, Zhang Q, Witley S, Blid Sköldheden S, Zentveld L, Vallöf D, Tufvesson-Alm M, Jerlhag E. ‘Semaglutide reduces alcohol intake and relapse-like drinking in male and female rats’.

Addiction Biology. 2022; 27(2):e13117. doi:10.1111/ adb.13117.
These concerns were raised to me when I interviewed many reputable scientists in the field.
9. Such harm to brain function as mentioned above may result in anhedonia or increased depression. Such harm to brain function as mentioned above may be related to the safety signal raised around suicide in relation to these drugs:
Brain effects are being actively explored for positive impact, but where there is impact there is always the risk of negative impacts also.
This 2023 online interview with an American researcher who is currently investigating semaglutide in relation to alcoholism makes it clear that anhedonia is widely discussed as a possible risk: https://news.okstate.edu/articles/health-sciences/2023/osu-chs-researcher-studying-weight-loss-drugs-alcohol-use-disorder-treatment.html
The European Medicines Agency released this press statement in July 2023 about the suicide safety signal which was raised by Icelandic doctors in relation to GLP-1 agonists: https://www.ema.europa.eu/en/news/ema-statement-ongoing-review-glp-1-receptor-agonists
These concerns were raised to me when I interviewed many reputable scientists in the field.
10. Even if Ozempic, Wegovy or other GLP-1 agonists are taken indefinitely, there are grounds to suspect that increasing tolerance or physiological and neural change may render the drug ineffective at weight control over time:
As the drugs are so newly-approved for treating obesity, it is hard to point to long-term studies indicating tolerance effects. However the rate of weight loss in the clinical trials seems to level off after several months on semaglutide, and there is an indication that weight may even be beginning to be regained at the end of the longest trial, STEP One: body weight change reached its nadir at week 60, with a slight uptick visible in the final 8 weeks on treatment. See Table 1 in: https://www.nejm.org/doi/full/10.1056/NEJMoa2032183
Interviews within my book make it clear that tolerance is well-known as a likely issue with long-term use of drugs.
11. Use of Ozempic, Wegovy or other GLP-1 agonists might result in such loss of pleasure from eating for some people, that harmful habits may take hold as some users may seek stimulation and pleasure in other ways, which may be personally and socially harmful.
This side effect is widely reported, and many of my own interviewees referred to it. See also, for example, patients interviewed in this article: https://www.nytimes.com/2023/04/21/well/eat/ozempic-side-effects-malnutrition.html
12. Despite the fact there is guidance given for Ozempic, Wegovy or other GLP-1 agonists that they should not be given to people with a BMI lower than 27, some people with eating disorders who are highly motivated to deprive themselves of food may get hold of these drugs (mainly through online prescriptions) and harm themselves as a result. This risk is being widely discussed:
UK eating disorders charity, Beat, issued this press release 8 March 2023, when Wegovy was approved by the NHS, saying that semaglutide is “very dangerous for those with eating disorders”: https://www.beateatingdisorders.org.uk/news/semaglutide-weight-loss-medication-very-dangerous-for-those-with-eating-disorders/
In the same month UK pharmacist Superdrug was cautioned for advertising the drug online – see reporting in the Guardian: https://www.theguardian.com/society/2023/mar/12/explainer-new-skinny-jab-has-been-approved-by-the-nhs-but-does-it-work-and-can-you-buy-it
And the Chair of the eating disorder faculty at the Royal College of Psychiatrists was quoted as saying these drugs pose “a real danger for abuse of the medication by those for whom there is no clinical need to use it”: https://www.independent.co.uk/news/health/nhs-weight-loss-jab-eating-disorders- b2296680.html
These issues were raised with me by some of the leading experts on eating disorders in the United States.
Please do let me know if you would like to make any other comments about Ozempic, Wegovy or other GLP-1 agonists. In the book in addition to discussing these potential risks I also discuss many benefits of the drugs.
I received the following reply from their spokesperson.
Our Response, attributable to a Novo Nordisk spokesperson:
Patient safety is paramount to Novo Nordisk, and we work closely with national health authorities to continuously monitor the safety profile of our medicines.
GLP-1 RAs have been used to treat type 2 diabetes for more than
15 years, and for the treatment of obesity for 8 years, including Novo Nordisk medicines that have been on the market for more than 10 years. Semaglutide has been examined in large global clinical development programs, and real- world evidence studies. Cumulatively it has over 12 million patient years of exposure.[i]
Treatment decisions should be made together with a healthcare provider who can evaluate the appropriateness of using a GLP-1 RA medicine based on assessment of a patient’s individual medical profile and in accordance with the medicine Summary of Product Characteristics.
Additional Information on background
Please note that for any questions not directly referenced below, we would refer you to the above statement.
Please note that we have reason to feel that your book may be listed on Bloomsbury with working title “The Magic Pill”. If this is the case please note that Ozempic/Wegovy are available as subcutaneous injections and not as oral formulations or pills. If the use of pill in the title is intended to refer to Wegovy or Ozempic we would flag that “magic pill” is an inaccurate characterisation of these medicines and the title should be updated.
Indications
Please note the indications for our semaglutide products. UK indications
Ozempic® ▼ (semaglutide injection) is indicated for the treatment of adults with insufficiently controlled type 2 diabetes mellitus as an adjunct to diet and exercise. Ozempic® is not licensed for the treatment of weight management.[ii]
Rybelsus ▼ (semaglutide tablets) is indicated for the treatment of adults with insufficiently controlled type 2 diabetes mellitus to improve glycaemic control as an adjunct to diet and exercise. Rybelsus® is not licensed for the treatment of weight management.[iii]
Wegovy® ▼ (semaglutide injection) is indicated as an adjunct to a reduced- calorie diet and increased physical activity for weight management, including weight loss and weight maintenance, in adults with an initial Body Mass Index (BMI) of ≥30 kg/m2 (obesity), or ≥27 kg/m2 to <30 kg/m2 (overweight) in the presence of at least one weight-related comorbidity.[iv]
U.S. Indications
Ozempic® (semaglutide) is FDA-approved for the treatment of type 2 diabetes, to improve blood sugar, along with diet and exercise, and reduce the risk of major cardiovascular events such as heart attack, stroke, or death in adults with type 2 diabetes and known heart disease. Ozempic® is not approved for chronic weight management. Please see Ozempic® full prescribing information here.
Rybelsus® (semaglutide) tablets is FDA-approved for the treatment of type 2 diabetes, to improve blood sugar, along with diet and exercise in adults with type 2 diabetes. It was clinically researched and studied in patients with type
2 diabetes. Rybelsus® is not approved for chronic weight management. Please see Rybelsus® full prescribing information here.
Wegovy® (semaglutide) is FDA-approved for chronic weight management in adults with obesity (BMI > 30), or overweight (excess weight) (BMI > 27) who also have weight-related medical problems, used with a reduced- calorie meal plan and increased physical activity. Wegovy® is also indicated for use in patients aged 12 years and older with an initial BMI at or above the 95th percentile for age and sex. Please see Wegovy® full prescribing information here.
NOTE: Although Wegovy®, Ozempic® and Rybelsus® all contain semaglutide, they are different products with different indications, dosages, prescribing information, titration schedules, and delivery forms. The products are not interchangeable and should not be used outside of their approved indications. Novo Nordisk is committed to the responsible use of our medicines and is taking multiple steps to ensure responsible use of our semaglutide medicines which are detailed on semaglutide.com.
Re: Question 1 on weight regain.
Results from the STEP trials demonstrate that weight regain is likely once treatment with Wegovy® is stopped. Clinical experts consulted by Novo Nordisk view obesity as a chronic disease that should be managed similar to other long-term health conditions such as diabetes and hypertension.[v]
NOTE: Please note that the Wilding reference you have shared is with regards to Wegovy® specifically and not other GLP-1 receptor agonists.
Re: Question 3 on any effect of GLP-1 Ras on unborn children during pregnancy.
The Summary of Product Characteristics (SmPC) for our semaglutide medicines state that these medicines should not be used during pregnancy. [ii], [iii], [iv] We recommend patients take semaglutide only for its approved indications and under the supervision of a healthcare professional.
Pregnancy or intention to become pregnant were exclusion criteria in our trials with semaglutide in both obesity and type 2 diabetes. There are therefore limited clinical trial data with semaglutide use in pregnant women. However, in the U.S., information related to pregnancy appears in Section & 8.3 of the U.S. Prescribing Information for both Ozempic® and Wegovy®.
There is an ongoing study to evaluate the safety of exposure to Wegovy® during pregnancy on Clinical Trials.gov here: https://classic.clinicaltrials.govct2/show/NCT05503927
Re: Question 4 on any risk of contracting thyroid cancer from GLP-1 medicines.
Recently the European Medicines Agency has conducted an independent investigation into any association between GLP-1 RA medicines (note: as a class, not only our medicines) and risk of thyroid cancer. On 27th October 2023, the EMA found no causal association between the GLP-1 RAs, namely – exenatide, liraglutide, dulaglutide, semaglutide, and lixisenatide – and cancer of the thyroid.[vi]
Re: Question 5 on acute pancreatitis and gastroparesis. Gastrointestinal (GI) events are common side effects of the GLP-1 class. For semaglutide, most GI side effects were mild to moderate in severity and of short duration. [ii], [iii], [iv] GLP-1RAs are known to effect a delay in gastric emptying, as detailed in the Summary of Product Characteristics (SmPC). [ii], [iii], [iv] Acute Pancreatitis, is also listed as an adverse reaction in the SMPC. [ii], [iii], [iv]
The long-term data from SELECT published recently with Semaglutide exposure over 39 months is reassuring that there is no increase in the risk of pancreatitis with Semaglutide 2.4 in comparison with placebo.
Re: Question 6 on any effect of semaglutide on body composition (including fat mass and lean mass).
In clinical trials for Wegovy®, Ozempic® or Rybelsus®, we did not specifically study the medicine’s impact on muscle mass. In a sub-study of 140 patients with a BMI of 40 or less conducted as part of the STEP 1 trial, dual-energy x-ray absorptiometry (DEXA) analyses suggested that treatment with Wegovy® was accompanied by reductions in both fat mass and lean body mass, with a greater reduction in fat mass than lean body mass. We recommend that any patients experiencing side effects while taking Wegovy®, Ozempic® or Rybelsus® contact their healthcare provider.
Re: Question 9 on any risk of suicidal ideation.
Novo Nordisk will continue to monitor reports of adverse drug reactions, including suicide and suicidal ideation, through routine pharmacovigilance and in cooperation with local health authorities.
In the U.S., FDA requires medications for chronic weight management that work on the central nervous system, including Wegovy® and Saxenda®, to carry a warning about suicidal behavior and ideation. This event had been reported in clinical trials with other weight management products. Novo Nordisk is continuously performing surveillance of the data from ongoing clinical trials and real-world use of its products and collaborates closely
with the authorities to ensure patient safety and adequate information to healthcare professionals. Novo Nordisk remains confident in the benefit risk profile of the products and remains committed to ensuring patient safety.
The long term data from SELECT published recently with Semaglutide exposure over 39 months is reassuring that there is no increase in the risk of psychiatric disorders with Semaglutide 2.4 in comparison with placebo.
Re: Question 12 on potential use of GLP-1 RAs by people living with eating disorders.
Novo Nordisk does not promote, suggest, or encourage off-label use, or misuse, or any of our medications. We do our best to ensure patients and doctors are educated about the appropriate use of our products and encourage healthcare providers to only prescribe the right product for the right patient.
Novo Nordisk is committed to the responsible use of our medicines and is taking multiple steps to ensure responsible use of our semaglutide medicines which for people living in the US are detailed on semaglutide.com.

Page 135/Page 163 – we need to think about these drugs very differently: The geneticist Tim Spector said it shouldn’t surprise us that so much of how these drugs work seems to come down to the brain. Ten years before, in 2013, he – along with other scientists – had carried out crucial work mapping many of the genes that relate to obesity. ‘We found about a thousand genes for obesity,’ and ‘it turned out when you saw what those genes did, most of it was affecting the brain.’ The genes that contributed to obesity ‘all seemed to be relating to the brain pathways, rather than purely energy pathways, or fat deposition pathways … It was all pointing to the brain, rather than the metabolism.’

Even when people take the drastic step of bariatric surgery, ‘Ray, Nickels, Sayeed and Sax (2003) found that patients with a history of sexual abuse lost significantly less of their excess weight at 1-year follow-up than those without such a history.’ Another study found that survivors of sexual abuse lost as much after surgery but were more likely to become depressed.

You have to sustain your body. So what we think is happening is the body is reorganising – renormalising the waves of hunger, fullness and so on, but it’s modified,’ and being experienced at a lower level. When his patients start to feel hungry again, they feel the drug has worn off. ‘I have to reinterpret what hunger is for them. That it’s completely normal. Congratulations! Everyone gets hungry but you don’t need as much food to feel full. Don’t overeat … Your weight is stable.’

Page 193/Page 224 – Why do we believe that making people loathe their bodies will make them take care of them?: Many people believe this stigma is a relatively recent invention. Dina Amlund has been carrying out academic research in Denmark on this topic, and she told me that she had been insulted and mocked for her weight since she was a child. In 2010, she began to research the history of how fat people had been seen in the past, because she had been told that not so long ago, ‘there were fat people and they were loved’, so ‘I wanted to go back, to find some sort of comfort – to see all the fat adoration I had heard about.’ She began to look at the most famous images and stories that people believe celebrated fat women in the past. What she saw took her aback. ‘I was like – oh no, we got it all wrong.’
The first thing that puzzled her is that throughout so much of recorded human history, people have worn shapewear – uncomfortable clothes, such as corsets, that sculpt their bodies into slimmer shapes. She asked: ‘If they liked fat people, how come we’ve never had a period of time without shapewear trying to shape the body and make it thinner?’ The oldest shapeware in the West was ‘worn by the Minoan people and it dates back to 1000 BCE and some say even longer, 1500–1600 BCE’. The women who wore them would look like ‘a very hourglassy hourglass – a very slender ideal. A thin ideal … To me, it looks very painful’ to wear.
Then she studied the famous paintings and statues from the Renaissance that are presented as evidence that people venerated fatness. ‘I always ask people to Google them to look at them to see … If they came alive, they would be able to walk into regular clothing shops and buy clothes there, and not plus-size clothes. So I don’t consider them fat.’ In fact, many of them are ‘definitely slender’. Look, she says, at Botticelli, who many people cite as proof that fat people were seen as beautiful in the past. ‘The newborn Venus is always the example. She’s just not fat. There’s nothing there.’
So she dug into the stories behind the few representations of genuinely obese people in the past that we have, and discovered a horror story. The artist Juan Carreño de Miranda painted a woman named Eugenia Martinez Valejo, whose images I have seen in the Prado Museum in Madrid. This work is often presented as evidence that in the Baroque Era, fat women were admired. Dina explained to me: ‘She was born to peasants in the second half of the seventeenth century and she was brought to court to work as a jester when she was six years old.’ She was very fat from a very young age, at a time when that was very rare. She was brought to court in effect as a ‘freak’, to be displayed as an amusement, alongside people with physical disabilities. ‘It was because she was fat that she was brought to court … She was there to be fat. That was her job’, and like the jesters, she was there to be humiliated. They would throw food at her. The two paintings Juan Carreño de Miranda did of her are titled Monster Nude and Monster Dressed. This was not a story of celebrating fatness – it was a story of sadistically abusing a fat child and young woman.
After learning all this, Dina told me, ‘At first, I was really sad. I came here [to this history] looking for friends’, and all she found was ‘enemies’. But ‘I do think there’s something very positive about it, and it is that we will never be able to untangle fatphobia if we don’t understand what a serious grip it has on us. Some people say “oh, it came with social media”, or “it came with Twiggy”’, while the American academic ‘Sabrina Strings argued it started in the 1700s with racism. And I would say – no, it could be used to enhance already existing racism because the world was so fatphobic already.’ This changed her own perspective. ‘Ever since I was a child, I’ve experienced horrible comments in public, and I used to [just] think this person is rude.’ Now, she also thinks that person is ‘a symptom of an oppressive structure that is not his own fault. It’s his responsibility what he says, but it’s not his fault that he thinks like that.’ This insight, she says, ‘made my life very different’, and spurred her to fight against this prejudice.

Page 196/Page 227 – has been dubbed the ‘obesity paradox’: K. M. Flegal, ‘Excess Deaths Associated With Underweight, Overweight, and Obesity’. The term ‘obesity paradox’ refers to findings that in some instances there are lower mortality rates for overweight people than for those with BMIs usually described as healthy, in certain situations or groups. Flegal and her colleagues were not the first to report on this phenomenon. It seems to have been identified as far back as 1985. Dr Kamyar Kalantar-Zadeh prefers the term ‘reverse epidemiology’ and was arguably amongst the first to highlight the issue. See also: R. Andres et al., ‘Impact of Age on Weight Goals’, Annals of Internal Medicine (1985), 103, pp. 1,030–3; H. Lennon, M. Sperrin, E. Badrick and A. G.

Page 198/Page 229 – the more obese a person becomes, the greater the risk to their health: The scientists I interviewed kept reiterating these broad points, with the same amount of sadness – and genuine compassion for the people who don’t want to believe it. Robert Kushner said people who say obesity doesn’t harm health are ‘ignoring all the science’. Graham MacGregor reiterated this point, and stated plainly: ‘It’s not their fault’ they are obese. ‘Let’s keep that clear. It’s
the food industry’s fault. But if you’re obese, you’re much more likely to die, you’re much more likely to get type two diabetes, you’re much more likely to have all sorts of complications.’
Page 198/Page 229 – a small body of scientific research based on a concept called ‘Health at Every Size’: See D. Clifford et al., ‘Impact of Non-Diet Approaches on Attitudes, Behaviors and Health Outcomes: A Systematic Review’, Journal of Nutrition Education and Behavior (2015), 47(2), pp. 143–55; L. Bacon and L. Aphramor, ‘Weight Science: Evaluating the Evidence for a Paradigm Shift’, Nutrition Journal (2011), 10(9), https://doi.org/10.1186/1475-2891-10-9; L. Bacon, J. S. Stern, M. D.

If these approaches really can increase people’s exercise levels, they could have a big impact on health – see for example this study (not a ‘Health at Every Size’ one), which found that an obese person in the ‘active’ group had half the risk of cardiovascular disease of someone entirely sedentary: X. Zhang et al., ‘Physical activity and risk of cardiovascular disease by weight status among US adults’, PLoS One (2020), 15(5), e0232893, doi:10.1371/ journal.pone.0232893.
Page 201/Page 232 – much more powerful changes than have ever been documented by changes in stress: Poverty and stress unambiguously do have negative health effects.

Page 204/Page 235 – In response to this critique, Katherine Flegal then did another large-scale study: K. M. Flegal, B. K. Kit, H. Orpana and B. I. Graubard, ‘Association of All-Cause Mortality With Overweight and Obesity Using Standard Body Mass Index Categories: A Systematic Review and Meta-analysis’, JAMA (2013), 309(1), pp. 71–82, doi:10.1001/jama.2012.113905.
Page 204/Page 235 – her published data did not properly exclude those groups: He organised a symposium at Harvard where he and several other speakers sought to rebut Flegal’s data. See V. Hughes, ‘The big fat truth’, Nature (2013), 497, pp. 428–30, https://doi.org/10.1038/497428a. This piece in Harvard’s ‘Nutrition Source’ blog from 2005 lays out some of Walter’s and his colleagues’ arguments against Flegal’s findings: https://www.hsph.harvard.edu/nutritionsource/2005/05/02/obesity-controversy/.
In 2013 on public radio Walter referred to Flegal’s 2013 follow-up study as ‘a pile of rubbish’; see ‘Shades of grey’, Nature (2013), 497, p. 410, https://doi. org/10.1038/497410a.

Bell et al., ‘The Natural Course of Healthy Obesity Over 20 Years’, Journal of the American College of Cardiology (2015), 65(1), pp. 101–2, https://doi.org/10.1016/j.jacc.2014.09.077. See also Nadja Hermann, Conquering Fat Logic (Scribe, 2019), p. 83. ‘Healthy’ and ‘unhealthy’ had to be very carefully defined in this study. ‘Metabolically healthy’ they defined as having less than two of the following symptoms: ‘high-density lipoprotein cholesterol level <1.03 mmol/l (men) and <1.29 mmol/l (women); blood pressure ≥130/85 mm Hg or use of antihypertensive medication; fasting plasma glucose level ≥5.6 mmol/l or use of antidiabetic medication triacylglycerol level ≥1.7 mmol/l; homeostatic model assessment of insulin resistance >2.87’.
Page 205/Page 237 – obesity made you eight times more likely to become unwell: In Conquering Fat Logic p. 83, Nadja Hermann writes: ‘Obesity is a bit like smoking: the tumours don’t start growing right after the first cigarette. For someone who is naturally prone to lung problems, it might take five years. Another person’s lungs might be able to take fifty years of constant damage.’ Bell, ‘The Natural Course of Healthy Obesity Over 20 Years’. Similarly, Krista Varady, who is a Professor of Nutrition, told me: ‘I think the thing people don’t understand is that when they are young and obese, their cholesterol levels are fine, their blood pressure is fine. But carrying that weight for a long period of time dramatically increases their risk of high blood pressure and high cholesterol levels and heart attacks’ later in life. ‘A lot of people in that movement are pretty young. They’re like “I’m healthy, I don’t understand – it’s not that big a deal.” But they’re not looking at longitudinal data that shows carrying obesity for a long time will put you at much higher risk of all these diseases that will lead to an early death … You just need to look at the longitudinal data.’

Page 207/Page 238 – no contradiction between these twinned goals: Dr Shauna Levy made similar points to me. She said: ‘it’s so complicated, because it’s such a good thing when it comes to body positivity … But we just know from the data that there’s harmful effects from this disease … They’re separate points. Why can’t we keep them separate? … I suspect that this movement is born out of people just being mistreated for so long – in this thin-centric, fat-phobic culture that we still live in – admitting there’s disease, and admitting there’s a problem would minimise their perspective … I think they’re coming from such a hurt place. You have to be very strong in your opinions to stand up for your cause, and if you relax on that, it always feels like defeat.’ To people who don’t believe that obesity harms health, she said, ‘I don’t know how to answer that other than – do you also not believe data? From my vantage point, most of the people who are fighting’ for fat pride ‘are young people. I don’t see a lot of sixty-five-year-olds as healthy at every size advocates … Sixty years of walking around with this sheer weight on your body is going to lead to problems… The more weight you put on, the more likely you are to develop another problem.’
many of her former friends lashed out at Shelley: As Shelley and I talked about this, I thought about a moment in the history of a community I belong to. In the early 1980s, the HIV virus began to spread, and gay men were one of the groups worst affected. This was because gay men on average have more sexual partners, and because the virus is more easily spread through anal sex. When scientists started to explain to gay men that they were at particular risk, some gay men heard it as yet more cruel stigma. They had spent their whole lives being told that they were sexually disgusting and immoral (often by doctors), and that they would be punished for it. Now, here was a group of scientists who seemed to them to be saying the same.
Some gay men rejected this message with fury. They insisted on keeping the bathhouses open. It’s very easy to understand why. They were good people, reacting in understandable ways. And – sadly – many of them as a result got sick. Some other gay men – like one of my heroes, the activist Larry Kramer – reacted differently. They said: we need to live in reality, and if we are at greater risk than other people, then we need to know that, and we need to take action together. Instead of denying the science, these gay men, who made up the majority, deliberately spread awareness of the best evidence among their community, and embraced measures like condom distribution and, eventually, antiretroviral drugs that reduced the risks.
Some of the Fat Pride movement – not all – seem to me to be a little like the gay men who said the scientists warning about AIDS were just homophobes in white coats. Some people in the Fat Pride movement argue that the only way to destigmatise obesity is to say that there is no difference between the health of non-obese and obese people. But nobody today would claim that the way to destigmatise HIV is to claim that HIV-positive people are exactly like HIV-negative people when it comes to health challenges. Indeed, one of the ways we reduced stigma in the end was by acknowledging the difference, and giving more help, support and care to HIV-positive people.
Tackling stigma does not require a fantasy of exact sameness. Pretending we are the same when we are not in fact ends up reinforcing the stigma, by denying people the help they need. Where there are differences, we need
to tell the truth about them in a spirit of love and compassion, and build practical solutions.

Most of its landmass cannot be used effectively for agriculture because it is too high, cold or steep … The soil tends to be poor, deposited black volcanic ash with little nutrient value. Even grass suitable for animals does not grow in much of Japan.’ They had to get their protein from the water.
Page 216/Page 248 – The blackness often comes from seaweed: There is a lot of evidence for this. In Tim Spector, The Diet Myth: The Real Science Behind What We Eat (Weidenfeld & Nicolson, 2016), pp. 137–8, Spector explains it is ‘an important source of iodine in preventing thyroid disease, and contains potentially beneficial antioxidants … Japanese who lived on or near the cost for centuries enjoyed eating seaweed in many different forms, for instance as additives to soups or salads or to wrap their raw fresh fish in … The average Japanese … consume[s] an amazing 5kg per person per year. This is neatly three times their digestion of dairy.’ In Michael Booth, Sushi and Beyond: What the Japanese Know About Cooking (Vintage, 2010), pp. 120–1, Booth explains that fifty types of seaweed are eaten in Japan: ‘There is every reason to believe konobu is one of the most significant foodstuffs in terms of the Japanese’s famed good health and longevity. It has more minerals than anything else they eat, including potassium, iron, iodine, magnesium and calcium, as well as vitamins B and C, and is thought to aid the removal of toxins from the body. Seaweed also contains lignins believed to prevent cancer. Plus, of course, it is fat- and calorie-free.’
