You don't have to read the book to get it

Here's the truth in 10 points

You go to the doctor. Maybe it’s your knee. Maybe it’s your breathing. Maybe you’ve been putting off going for months because you already know what’s coming.

Before they’ve examined you… Before they’ve run a single test… Before they’ve even really looked at you, they tell you to lose weight.

The entire consultation revolves around a number on the scale that somehow explains everything, even though it explains nothing.

You leave without answers. Without a diagnosis. With a leaflet or a GLP-1 prescription or a referral to a bariatric surgeon, and the feeling you’ve had a hundred times before: what’s the point?

You’ve spent years believing your body is the problem. That if you could just fix your weight, everything else would follow. That you don’t deserve the same care as everyone else until you do.

Hear this: everything you’ve been told about weight and health is built on a lie. Not a misunderstanding. Not an honest mistake. A lie. One that has been repeated so many times, by so many people in white coats, that it became gospel.

There's no such thing as a healthy weight

When a doctor tells you you weigh too much, they’re implying there’s a right amount to weigh – that the line between ‘normal’ and ‘too high’ is more than just an arbitrary cutoff. It isn’t.

The concept of a ‘healthy weight’ wasn’t built on the same kind of evidence we used for other markers like blood pressure – where researchers tracked thousands of people over decades, identified a biological mechanism, and proved that treating it improved outcomes.

Weight has none of that.

What it has instead is Louis Dublin and the Metropolitan Life Insurance Company maximising profits by charging fat people higher premiums. How? By leaning into society’s hatred of fat people and using actuarial data – as opposed to clinical evidence – to argue that heavier people are unhealthy.

It has Ancel Keys, who in 1972 created a statistical tool designed to one day prove what he already believed to be true – that being fat was bad for your health. There was no evidence to support his theory, but that didn’t stop him and his team from creating the Body Mass Index using data from just 7,400 predominantly white men.

Believe it or not, Keys and the team explicitly warned the medical community that BMI was only meant for population studies, not individual assessment. Less than a decade later, healthcare professionals were measuring height and weight to determine whether their patients were too fat, and they haven’t looked back. Too fat for what, exactly? We still don’t have the answers.

Then there’s the 1998 WHO report, funded by drug companies who had weight-loss drugs coming to market that same year, which turned ‘obesity’ into a disease and created arbitrary BMI cutoffs that turned millions of people into sick patients in need of treating overnight.

To be clear: ‘obesity’ is not a disease. It’s a statistical category dressed up as a diagnosis. Fat (adipose tissue) is an organ with essential physiological functions including hormone production, energy storage, immunity. You cannot survive without it. Having more of something normal is not pathology. It’s just discrimination masquerading as medical care.

It has been over a century since so-called experts with a clear underlying agenda – to make as much money as possible – started lying to the general public about what constitutes a healthy weight. We still have no clear evidence that being fat causes any health issues. We have no biological mechanisms that stand up to scrutiny. And we have no evidence that losing weight improves health outcomes in any meaningful way.

The next time a doctor wants to weigh you to calculate your BMI, remember that BMI has never been validated as a disease marker. Half the time it fails to measure ‘excess fat’ accurately (whatever that means). BMI has no bearing on your health, and your doctors can’t use it to sell you weight loss or deny you treatment if they don’t know what it is.

Diets don't work because your body won't let them

No matter how hard you worked at it, diets always fail. Not because of anything you did or didn’t do – because of hundreds of thousands of years of evolution. It has nothing to do with willpower and everything to do with human biology.

Your body is designed to hold on to its fat stores and responds to energy restriction the same way every single time: by slowing your metabolism and increasing your appetite. Together, these are called adaptive thermogenesis, and they are not a sign of weakness. They are a survival mechanism written into your DNA.

That’s the reason the weight loss began to plateau and then stopped altogether. That’s the reason you started to regain weight despite your best efforts. And that’s the reason the weight-loss industry is able to keep you in a constant cycle of self-blame and false hope.

They take credit for the first part of the weight loss cycle, and blame you for the second. Then they promise things will be better next time, even though that couldn’t be further from the truth. The damage to your metabolism lasts long after the diet ends, which means each weight-loss attempt requires more extreme methods to achieve the same results.

You have nothing to be ashamed of – they’re the ones exploiting you for profit.

In 1992, the National Institutes of Health convened a conference of ‘obesity’ experts who concluded that “one to two thirds of all weight lost is regained within a year, and almost all of it within five years.” More than thirty years later, nothing has changed.

For every kilogram of weight you lose, your appetite increases by around a hundred calories. The more weight you lose, the hungrier you become. That’s not greed. That’s not something you can ignore by trying harder. It’s like asking someone to hold their breath underwater – no matter how hard you train, eventually you need to surface for air.

Dieting isn’t just futile – it’s counterproductive. Studies have shown that people who went on one single diet were two to three times more likely to be heavier than their identical twin by age 25. The more you diet, the fatter you become. The weight-loss industry knows this – it’s part of their business model.

The best way to gain weight is to attempt to lose it.

Being fat is not what's making you sick

Doctors are making you sick

Most doctors have been trained to believe that fat is dangerous and that weight loss helps. They haven’t questioned it, because everyone everywhere knows it’s true. Except it isn’t.

A 2003 study of primary care physicians found the majority viewed their fat patients as “awkward”, “unattractive”, “ugly”, and “noncompliant”. They described them as “weak-willed”, “sloppy”, and “lazy”. That same study found that doctors allowed this prejudice to influence their clinical decisions – ordering more tests but spending less time, expecting unrealistic weight loss, and admitting to using scare tactics to achieve it.

You know this already. You feel it the moment you walk into their office. You can tell by the way they look at you before you’ve even had a chance to sit down. Doctors are just as biased as everyone else. In many cases, they’re actually worse.

The negative attitudes, beliefs, and assumptions that doctors hold about you impact the way they treat you. They automatically dismiss your symptoms as weight related without considering other possible diagnoses. Instead of evidence-based treatments, they send you away with weight-loss advice. They blame you for your medical condition and shame you into considering weight-loss injections or surgery. As a result, important diagnoses are missed and essential treatment is delayed.

How are you supposed to trust your doctors when you know deep-down how they feel about you? If you can’t trust them, how are you supposed to confide in them? If you can’t confide in them, how are they supposed to diagnose and treat you? Even if they do get the diagnosis right, why would you follow their advice? Come to think of it, why bother visiting the doctor in the first place?

Studies have shown that fat people avoid seeking medical attention because they fear the shame and stigma. Fat people are less likely to engage in cancer screening and immunisation programs, even though they recognise the importance and worry about the potential consequences.

With all this in mind, is it any wonder that fat people are more likely to develop certain medical conditions?

Studies have shown that doctors are one of the most common sources of weight stigma, which impacts society as a whole beyond the four walls of their office. The consequences go far beyond inequalities in healthcare — lower wages, fewer opportunities, social isolation. Among other things, weight stigma has been shown to increase your blood pressure, reduce insulin sensitivity, and cause chronic low-grade inflammation.

Weight stigma kills people. During the swine flu pandemic of 2009, fat people had 81 percent higher odds of dying. Researchers initially assumed this was because their bodies were already diseased. But several years later, research found that the higher rates of mortality only applied to fat people who didn’t receive timely treatment. Fat people weren’t dying of swine flu because of their weight. They were dying because they received anti-viral treatment later than thin people.

Doctors have a collective responsibility to end medical weight stigma. To challenge their own anti-fat bias as well as the systems that are designed to harm their patients. Doctors have a responsibility to stop perpetuating harmful stereotypes and to keep blame and shame out of the consulting room.

You shouldn’t have to fight for basic respect every time you need medical care. But until the system changes, you have the right to tell them to stop. To stop weighing you when it’s not clinically necessary and to stop offering you unsolicited weight-loss advice. To investigate your symptoms instead of automatically dismissing them as being weight-related, and to offer you treatments that focus on your symptoms as opposed to the number on the scale.

The treatment is causing the disease

In 1944, physiologist Ancel Keys asked a group of conscientious objectors to volunteer for a starvation experiment. For six months, they ate around 1,800 calories a day – not far off the recommended daily intake for most adults nowadays. The results: muscle wasting, dizziness, chronic fatigue, hair loss, obsession with food, impaired concentration, mood collapse, and a profound psychological fixation on eating that lasted years after the experiment ended.

Keys’ volunteers spent six months in these conditions. Your starvation lasted years. Some of you are still watching what you eat. Keys’ volunteers consumed 1,800 calories a day and struggled to go for a daily walk, let alone anything else. Nowadays doctors prescribe very-low calorie diets (less than 800 calories a day) and expect you to go about your day without any issues.

Just because you’re fat doesn’t mean you are somehow immune to the physiological and psychological effects of starvation. And make no mistake, that’s exactly what intentional weight loss involves. Consuming fewer calories than you need to survive – whether that’s through dieting, taking medication that suppresses your appetite, or cutting out parts of your digestive system – is starvation. It places your body under extreme stress and interferes with your metabolism, hormonal balance and nervous system.

Eating disorders have the highest mortality rate among all mental health conditions. Dieting is the biggest risk factor for eating disorders. One study found that adolescents who used severe weight control behaviours were 18 times more likely to develop an eating disorder. And yet doctors insist on putting fat teenagers on diets.

What we label disordered eating in thin people, we call a ‘healthy lifestyle change’ in fat ones. Doctors are literally prescribing eating disorders to their fat patients.

Eating disorders affect people of all sizes. Fat people with restrictive disorders are just less likely to be diagnosed, because the stereotype says they can’t have one. Being fat doesn’t protect people from the physical consequences of eating disorders, yet most services require people to be below a certain BMI before they will even consider assessing them. Fat people with eating disorders are often left in the cold, without a diagnosis or a treatment plan.

And then there’s weight cycling – the repeated losing and regaining of weight that is the almost-inevitable result of every diet. It has been shown to increase mortality, raise blood pressure, alter insulin sensitivity, and damage a number of your internal organs. Researchers have found that weight cycling can account for all of the excess mortality in the Framingham Heart Study that had previously been attributed to weight.

When doctors prescribe weight loss, they are prescribing starvation. They are putting you at risk of an eating disorder and all the physiological consequences of the inevitable weight cycle. They are prescribing something that is likely to harm your health as opposed to improve it.

Weight loss won't improve your health

There is no evidence that losing weight improves your health. It doesn’t increase your life expectancy. It doesn’t reduce your risk of developing a disease, and it doesn’t improve your symptoms or prognosis once you have one. Whilst it may improve health markers in the short term, weight loss has never been shown to improve health outcomes in the long term.

The “obesity paradox” is well documented and consistently ignored. Fat people with heart disease, kidney disease, diabetes, dementia, and COPD have lower mortality rates and better prognosis than thinner people with the same conditions. Fat people have better survival rates after surgery. Whilst researchers have come up with a number of theories to explain away this phenomenon, none of them hold water. It’s only a paradox if you believe being fat is unhealthy in the first place. Turns out, being fat might actually be protective in some circumstances.

You may feel better after starting a diet. The evidence suggests the most likely explanation is a combination of the placebo effect, the improved sleep, movement, and hydration that tend to accompany any deliberate change in routine, and the temporary lift of receiving attention and compliments. When adaptive thermogenesis kicks in and the weight starts to return – as it almost always does – none of those benefits last.

We can't trust the guidelines

The clinical guidelines your doctor follows were not assembled by a group of neutral experts dispassionately reviewing evidence. They were put together by committees whose membership is largely determined by the organisations that convene them, with no independent ethics oversight, and populated with experts whose financial relationships with pharmaceutical and weight-loss companies are declared but rarely acted upon.

The NICE guidelines on “overweight” and “obesity” management have a 19-page stakeholder list that includes drug companies, weight-loss companies, and bariatric surgery societies. The evidence underpinning their recommendations is graded mostly “low” or “very low” quality. In cases where evidence doesn’t exist, the committee makes recommendations anyway on the basis of ‘clinical consensus’ – a room full of handpicked experts agree that something sounds right and that’s the end of it.

Since there’s no decent quality evidence that weight loss improves health conditions, clinical guidelines shouldn’t be recommending weight loss. Experts wouldn’t recommend a drug or procedure that has never been shown to be effective – why is weight loss any different? Worse still, most guideline committees don’t even consider the numerous risks and side effects of intentional weight loss, let alone balancing them against the potential benefits. It’s as if they don’t care how much fat people have to suffer, just as long as they’re thinner by the end of it.

The clinical guidelines your doctor follows – the ones that tell them to put you on a diet, refer you for surgery, prescribe weight loss drugs – are not based on strong evidence. They reflect who funded the research, not what the research actually shows. And then there are the cases where the guidelines are not just weak – they are actively deciding who gets to live.

Fat people are routinely denied IVF treatment, yet the evidence shows IVF works just as well in fat people as in thin people. Research has shown that making fat people lose weight before fertility treatment actually reduces their chances of a successful birth. Fat people are denied organ transplants, despite evidence that outcomes after kidney and liver transplants are comparable regardless of BMI. This is medical discrimination and it is ethically indefensible. Some might go so far as to call it modern day eugenics.

None of this is individual doctors making bad calls. This is policy. The guidelines are not the truth. They are a negotiated settlement between the evidence and the interests of the people in the room. Guidelines committees are enshrining discrimination into the foundations of medical practice and calling it evidence-based care.

This isn’t bad doctors — it’s bad medicine.

It’s all about the money

In 2025, Mounjaro and Ozempic were the second and third highest grossing drugs in the world. In one year, semaglutide alone earned Novo Nordisk $31 billion. Tirzepatide earned Eli Lilly $36.5 billion. That didn’t happen by accident. Over the last few decades, the pharmaceutical industry created the weight-loss market by turning a natural variation in body size into a disease. They took control of the narrative in order to convince you that even though you feel well right now, being fat means disaster is lurking just around the corner.

In 2001, the American Diabetes Association’s PR department invented “prediabetes” – a condition that doesn’t cause symptoms, that most people never progress beyond, and that has been known to resolve on its own years down the line. Weight loss does not prevent people with “prediabetes” developing diabetes in the future, but that doesn’t stop the ADA from recommending it. One in three Americans meets the criteria for a “prediabetes” diagnosis, giving doctors a legitimate excuse to recommend weight loss to over a hundred million people across the country. And it just so happens that two of the ADA’s three founding pathway sponsors are Novo Nordisk and Eli Lilly.

Drug companies pay for the research they use to promote their drugs. The landmark study that got semaglutide approved for weight loss was co-authored by fifteen people, all of whom had financial ties to Novo Nordisk. Three were employees. Two actually owned stock. Novo Nordisk designed the trial, oversaw its conduct, collected and analysed the data, and paid a medical communications company to write the manuscript. This is standard industry practice, and that is exactly the problem.

Drug companies also pay healthcare organisations to promote their message. The World Obesity Federation – a registered charity – received two thirds of its £2.1 million income in 2024 from Novo Nordisk and Eli Lilly. It runs “World Obesity Day” every year, which typically coincides with Eating Disorder Awareness Week. It produces journals, conferences, and clinical education programmes for healthcare professionals, substantially funded by the same two companies. This is how the pharmaceutical industry shapes public opinion and medical culture without anyone having to name what it actually is.

This is not a conspiracy theory. The payments are disclosed – you just have to look hard for them. The pattern is clear: create the disease, fund the research that proves it exists, fund the organisations that write the guidelines, fund the charities that advocate for treatment, train the doctors who prescribe the drugs, and market directly to the patients who take them.

Mounjaro and Ozempic are the latest chapter in a story that has been running for over a century. The drugs change. The script doesn’t.

The system is designed to harm you

The weight-loss agenda begins in childhood because the weight-loss industry understands that lifelong customers are made young. Get children believing their bodies are wrong before they’re old enough to question it, and you have a market for life. Schools enforce “healthy lunchbox” policies. Teachers with no nutrition training police what children eat. Health professionals are placing toddlers on diets. In 2020, two teenagers were removed from their safe and happy home by West Sussex social services because they were fat and had failed to lose enough weight. Academic experts have even published papers suggesting that removing children from the home may be a “positive experience” in terms of weight management.

Let’s be clear: weight management attempts are completely futile in children but experts are recommending them anyway. All the studies show “very little meaningful impact” but remain part of the UK guidelines because removing them would be “too radical”. In 2022, The American Academy of Pediatrics explicitly reaffirmed their own report from 2016 which advised against talking about weight with children or recommending dieting or diet pills. Then, in 2023, they released guidelines recommending diets for children as young as two, GLP-1s from age eight, and bariatric surgery from age twelve. The AAP is reported to have received at least two million dollars from weight-loss drug manufacturers since 2012.

The weight-loss agenda doesn’t end when you grow up. It just intensifies. If you need surgery, chances are you’ll be told you’re too fat to be listed. But fat people have lower mortality rates during surgery than thin people. The Preoperative Mortality Predictor Score shows that losing more than ten percent of your body weight in the six months before surgery actually increases your risk of dying on the table. Weight loss prior to joint replacement does not improve outcomes – in fact, studies have shown that patients who lost weight before surgery had a greater rate of complications than those who didn’t.

This is the catch-22 by design. You’re told you need to lose weight before they’ll operate on your knee. But to lose weight, you need a functional knee. Your options are starvation, medication, or bariatric surgery – all of which carry risks and none of which have evidence that they improve surgical outcomes. Only seven percent of people waiting for joint replacement ever lose enough weight to qualify. The rest are discharged. Out of sight, out of mind. The weight-loss industry has convinced the medical profession to leverage your healthcare in order to maximise profits.

It’s hard to accept that the healthcare profession is actively working against you, but it’s hardly the first time it has happened. Doctors have repeatedly used “health concerns” to justify the pathologisation of people they deem deviant – homosexuality remained in the International Classification of Diseases until 1990. The statistical methods underpinning modern research were created by eugenicists. Much of our knowledge of human anatomy came from the bodies of enslaved Black people used without consent. Dr J Marion Sims developed gynaecological surgery by experimenting on enslaved Black women without anaesthetic. The Tuskegee syphilis study ran for decades after penicillin became available. Nazi doctors experimented on and murdered countless innocents. History is not a series of isolated mistakes. It is a pattern. And fat patients are the current chapter.

The weight-loss industry created a disease to sell a cure. They’ve captured the research, the guidelines, the healthcare organisations, the conferences, and the training programmes. They’ve started on the children. They’ve made being fat a barrier to lifesaving treatment. And they’ve done it all in the name of your health. The system is broken and is designed to harm, oppress, and exploit you simply because you are fat.

You can’t wait for the medical profession to turn around and do the right thing, but you do get to say no. No to being weighed for no reason. No to unsolicited weight-loss advice. No to weight-loss prescriptions. No to weight-based discrimination.

Not just no — No Weigh.

Here's what good healthcare actually looks like

Good healthcare for fat patients isn’t a radical concept. It isn’t a new standard that needs to be invented or a favour that needs to be granted. It is already written into the foundations of medical practice. Doctors just need to start following it.

Every doctor is bound by four ethical principles: autonomy, beneficence, non-maleficence, and justice. Autonomy means you have the fundamental right to make informed decisions about your own healthcare without coercion. Non-maleficence means doctors must do no harm – including causing offence, which explicitly constitutes harm under medical ethics. Beneficence means your doctor must always act in your best interest, which they cannot do without first taking your wishes into account. Finally, justice means fair, equitable treatment of all patients without discrimination.

These are not aspirational guidelines. They are the foundations of medical practice, and when one is compromised, everything else is at risk. Domain Two of Good Medical Practice (the standards expected of every doctor registered with the General Medical Council) states explicitly:

“You must treat patients fairly. You must not discriminate against them or allow your personal views to affect your relationship with them, or the treatment you provide or arrange. You must not refuse or delay treatment because you believe that a patient’s actions or choices contributed to their condition.”

Doctors are also told to treat patients with “kindness, courtesy and respect”, to listen to them, and to recognise their knowledge and experience of their own health. This is already in the handbook. In black and white. For all to read.

Informed consent is also already a legal requirement. Before recommending any treatment – including weight loss – a doctor must tell you the benefits, the risks, and the alternatives (including doing nothing). They must not omit the parts that don’t fit their narrative. Which means that before recommending weight loss, they are obligated to tell you it is temporary in almost all cases, explain the risks of weight cycling and disordered eating, and offer you alternative treatments that address your actual condition directly. If they don’t, they are not meeting the basic legal standard of care.

Crucially, autonomy overrides everything else. You can refuse to be weighed. You can refuse to discuss weight loss. You can refuse a weight-loss prescription. You can tell your doctor never to raise your weight again without your explicit consent, and ask them to document that on your notes. No is a complete sentence. Doctors cannot demand that you defend your decision, and they cannot refuse to treat you because you declined their advice. That is explicitly prohibited under the very guidelines they are supposed to follow.

None of this is radical. None of this is new. Doctors treating fat patients with the same standard of care they extend to everyone else – investigating symptoms, offering evidence-based treatments, respecting consent, and keeping their personal views out of the consulting room – is not asking for special treatment. It is asking for basic medicine.

You deserve that. You are entitled to it. And now you know exactly what to ask for.

This is just the beginning

This is not a fringe argument. Every claim on this page is drawn from peer-reviewed research, clinical trials, and the published words of the people who built the system. The full evidence – every study, every conflict of interest, every paper they hoped you’d never read – is in the book.
