Does Dieting Work? An exchange of letters with Helen Pluckrose

This is an online debate Helen Pluckrose and I had at the unfortunately defunct website in 2020 and 2021. I’m posting it here for preservation. I’m not sure I got all the formatting right, but I did my best with it.

I haven’t changed the words at all, even where I’d like to.  :-)

Thanks to Helen Pluckrose for her kind permission to reprint her letters here.

Dear Helen,

Hi! I’m writing to respond to your open letter, “on Fat Scholarship and Activism.”

A thousand words seems cruelly scant to me, but I’ll do my best.

For space reasons, I won’t dig into our “obesity vs fat” semantic disagreement. I suggest we each use our preferred word, neither making a fuss about the other’s choice. (Ditto for “fat acceptance” vs “fat activism.”)

Part 1: Your charges against the fat acceptance movement.

Your criticisms of fat acceptance are a mix of cherry-picked examples and uncharitable readings.

For instance, you say where fat activism “could oppose discrimination against obese people in the workplace, it goes on about ‘romantic discrimination.’” But the linked article contains only three paragraphs about “romantic discrimination,” a fraction of a much longer piece. (And do you really think cultural components of attraction aren’t worthy of being written about? I can’t agree.)

Your claim that fat acceptance “doesn’t do this kind of work” – meaning opposing things like workplace and medical discrimination – is staggeringly wrong. I could provide a hundred links of scholars and activists addressing those issues, but since time  is limitedhopefully just ten will prove my point.

Your other indictments followed a similar pattern, but with only 1000 words, I must move on!

(This article by Angie Manfredi, aimed at teens, is a non-comprehensive but accurate overview of fat acceptance’s goals. And Yasmin Harker created this useful bibliography of academic works about fat rights and fat discrimination.)

Part 2: Why I’m Generally Anti-Diet

We both want to end stigma and discrimination against fat people. Where we disagree (if I’ve understood correctly) is that you think fat people should try to not be fat, and that fat people are by definition unhealthy.

Accepting for a moment, for argument’s sake, that fat is unhealthy, that doesn’t necessarily lead to the conclusion that most fat people should try not to be fat.

First, I’ll stress that no one is under any obligation to maximize health. Exercise and cooking can take time, space, money, and mental energy which not everyone has. And people can legitimately prioritize other things.

But some fat people do wish to prioritize their health. Shouldn’t those fat people be encouraged to lose weight?

Some should – people with specific, serious conditions that weight loss could help (even if they’d still be fat).

But for 99% of fat people, I’d say not. The evidence is clear that weight-loss plans don’t work for the large majority. Most never lose a significant amount of weight – certainly not enough for a fat person to stop being fat. And usually whatever weight is lost – or more – comes back within five years. This causes mental anguish, because failure to lose weight, or to maintain weight loss, easily turns into self-hatred. If the person tries multiple times (as is common), the physical effects of yo-yo dieting can be very harmful.

Wayne Miller, an exercise science specialist at George Washington University, wrote:

There isn’t even one peer-reviewed controlled clinical study of any intentional weight-loss diet that proves that people can be successful at long-term significant weight loss. No commercial program, clinical program, or research model has been able to demonstrate significant long-term weight loss for more than a small fraction of the participants. Given the potential dangers of weight cycling and repeated failure, it is unscientific and unethical to support the continued use of dieting as an intervention for obesity.

Am I saying fat people who want to be healthier should give up? Absolutely not. I’m saying becoming healthier doesn’t require futile attempts to lose weight.

Please look at this graph. (Source.)

It shows likelihood of mortality as it relates to weight and four other characteristics: fruit and vegetable intake, tobacco use, exercise, and alcohol. These are sometimes called the “healthy habits.”

On the left side of the graph, fat people who practice no “healthy habits” – smoking, no veggies, immoderate drinking, no exercise – have a much higher mortality risk than so-called “normal” weight people with unhealthy habits (although the “normals” have elevated risk too).

On the right end of the graph, fat people who practice all four healthy habits have a mortality risk that’s just barely higher than their thinner counterparts. More importantly, we can see that fat people who practice all four healthy habits benefit enormously, compared to fat people who don’t. (“Normals” benefit enormously from these healthy habits, too.)

Most fat people can’t permanently lose enough weight to stop being fat. But most fat people can eat more veggies, can not smoke, can limit ourselves to one glass of hootch a day, can add moderate exercise to our lives. These things aren’t always easy, but they are all much more achievable, for most fat people, than stopping being fat.

Achievable advice is better than unachievable advice. There’s a positive way forward for most fat people who want to be healthier – one that’s more likely to work, and less likely to encourage self-hatred, than trying to stop being fat.

One final thought: stigma against being fat may be more harmful than fat itself.

These findings suggest the possibility that the stigma associated with being overweight is more harmful than actually being overweight… Growing evidence suggests that weight bias does not work; it leads to greater morbidity and, now, greater mortality.(See also.)

Could we get rid of weight bias while still holding the belief that fat people must lose weight? I doubt it. Reducing stigma could do more for fat people’s health than reducing waistlines.

There’s so much more to say (harms of dieting; benefits of a Health At Every Size approach; how HAES can help with disordered eating; etc), but I’m out of space.

I hope this letter finds you happy, well, and socially distanced someplace very cozy.

Best wishes, Barry

Dear Barry,

Thank you for responding to my open letter.

They are not cherry-picked examples unless you mean that I am picking examples of elements of fat activism that worry me and only criticising them. This is quite a standard practice.

I know that fat activism and fat scholarship can address important issues but this is why it is so frustrating when it focuses on “fatphobic” discourses instead. I learnt about the connection between poverty and obesity and about medical discrimination in the Fat Studies Reader and these are things that could be focused upon empirically. Unfortunately, it spends much more time going on about fatphobia and how science is bad.

I think claims to be ‘anti-diet’ are missing the point and it also encapsulates the misdirection that fat activists frequently engage in.

There are two definitions of the word ‘diet.’ One refers to what someone eats and the other refers to a short-term weight loss plan. I think we can safely assume that we are both in favour of people eating and both against short-term weight loss plans.  Short-term weight loss plans cannot achieve a long-term healthy weight by definition. In the same way a six-week non-smoking plan after which you go back to smoking cannot achieve long-term non-smoking. Nevertheless, the reason the majority of people (worldwide, not in America) are not obese is their diet. Either intuitively or consciously they eat the right amount of calories they need to be neither dangerously underweight or dangerously overweight. The scientist you cite as saying there is no evidence that weight loss plans can achieve long-term weight loss is necessarily right but he seems to be talking to the people who only tried short-term ones and he might get different answers if he asked people who are not overweight why they are not. Some, like my husband (curse him) will doubtless say they don’t have to think about their diet to maintain a healthy weight but others, like most of my friends, will say they do it by watching what they eat.

You urge me to consider that cultural components of  attraction could be worth writing about and I don’t necessarily disagree. I do, however, think we should pay more attention to cultural components of obesity because it kills people.  Even in the countries like mine and yours where obesity has reached epidemic proportions, this was not the case 100 years ago or even 50 years ago. The fact that mass obesity is such a new phenomenon in some countries but still not in others indicates that it is not a biological inevitability but a product of culture. The fact that it is a causal factor for so many diseases and early death means we should try to do something realistic to address this. I agree that simply telling people to eat less and move more is likely to be unhelpful.

I agree that no-one is under any obligation to maximise their health. I have little sympathy with libertarian views that use obesity as an argument against people being required to contribute towards a nationalised healthcare service. My own father was assertive in his decision to smoke and he maintained that he was right to choose a more enjoyable life over a longer one even when he was dying of lung cancer.  I absolutely support him in that although, selfishly, I’d rather he were still alive.

I agree with this:

Achievable advice is better than unachievable advice.

However, I am sceptical of this:

But most fat people can eat more veggies, can not smoke, can limit ourselves to one glass of hootch a day, can add moderate exercise to our lives. These things aren’t always easy, but they are all much more achievable, for most fat people, than stopping being fat.

It seems unlikely to me that people who find it very difficult to refrain from eating too many calories will find it much easier to commit to more vegetables, not smoking, drinking in moderation and exercising. However, I agree that thinking of weight loss in terms of making healthier choices is more likely to be helpful than thinking of it as stopping being fat.

I think you are being defeatist. What the evidence that people find it very difficult to  lose weight and maintain that weight loss suggests is not that obese people should stop trying to lose weight and maintain that weight loss but that the currently advocated ways for doing so are not adequate. We know how people get fat and stay fat. What we are failing to address is why they do so. This is what we need research into on both a social and psychological level. What has changed in society that makes obesity an epidemic right now? Why do so many people find maintaining a healthy weight so difficult psychologically? What will realistically help them overcome this?

Your thesis seems to be: Obesity is unavoidable so we can either continue to have a stigma against obesity and make fat people both fat and miserable or we can get rid of the stigma against obesity so that fat people can be fat and happy.

Mine is: Obesity is a new problem so we know it is avoidable. We can put our efforts into problematising the people addressing obesity as a problem or we can address the problem of obesity while also addressing  discrimination & stigma and not being arseholes to obese people.



P.S – Yes, I am self-isolating quite comfortably, thank you. My husband has had to take a furlough from work to protect me because I am particularly vulnerable to complications of the coronavirus because I am obese. :-p

Dear Helen,

Thanks for responding!

Our disagreements are legion but our word count isn’t, so I’ll get right into it.

You’re right, it’s not cherry-picking to criticize specific claims. But it is cherry-picking to treat an unrepresentative example as representative. You cherry-picked several times, such as saying fat acceptance doesn’t address workplace and medical discrimination but instead “goes on about romantic discrimination.”

You deny Dr. Miller’s claim that no “weight loss diet” has been shown to work[*] in a peer-reviewed study, by saying  “diet” means only “short-term” weight loss plans, a distinction not found in any dictionary I checked. As Dr. Miller’s quote said, he was looking at “long-term” weight loss.

No commercial program, clinical program, or research model has been able to demonstrate significant long-term weight loss for more than a small fraction of the participants.

Not a single weight-loss model – including long term approaches – has ever been shown to work in a peer-reviewed controlled clinical study.

There have been hundreds of tries. Anyone with a method scientifically proven to really, permanently work would become a billionaire. And yet, as Mann points out, not a single weight loss plan can even meet Medicare’s standards for effective health treatments.

Reviews of the scientific literature on dieting generally draw two conclusions about diets. First, diets do lead to short-term weight loss. One summary of diet studies from the 1970s to the mid-1990s found that these weight loss programs consistently resulted in participants losing an average of 5%–10% of their weight. Second, these losses are not maintained. As noted in one review, “It is only the rate of weight regain, not the fact of weight regain, that appears open to debate.”

(When Mann says “diet,” she doesn’t mean only short-term plans.)

Weight-loss advocates deny this reality – a finding that’s been in scholarly papers for decades and is unchanged today. They insist that empirical results don’t apply to whatever approach they favor (often called a “lifestyle change”).

Whatever they call it, it’s never been proven to work.

If we can’t acknowledge that, how can we have a real conversation about what fat people should do?

It is irresponsible for society to pressure us to stop being fat, when there’s no effective method for permanently losing even 5-10% of body weight, let alone the much larger amount someone like me would have to lose to stop being fat.

Now consider that weight-loss plans often leave people at higher mortality risk, less happy, and – by the way – fatter than when they began.

Proposing a treatment for being fat that’s more likely to harm patients than work isn’t just irresponsible. It’s cruel. Especially when there’s a better way.

Helen, you were skeptical that fat people could successfully pursue other routes to health, like exercise, not smoking, drinking moderately, and eating their veggies. Even though you were responding to an empirical study that included many fat people who did exactly those things.

(Are fat people especially bad at quitting smoking? This study found no connection between weight and ability to quit smoking; another found fat smokers were better at quitting.)

The truth is, keeping weight off is much harder than eating veggies or moderate exercise. Probably even harder than quitting smoking. Because our brains don’t want us to lose weight. Neuroscientist Sandra Aamodt explains:

The root of the problem is not willpower but neuroscience. Metabolic suppression is one of several powerful tools that the brain uses to keep the body within a certain weight range, called the set point. The range, which varies from person to person, is determined by genes and life experience. When dieters’ weight drops below it, they not only burn fewer calories but also produce more hunger-inducing hormones and find eating more rewarding….If someone starts at 120 pounds and drops to 80, her brain rightfully declares a starvation state of emergency, using every method available to get that weight back up to normal. The same thing happens to someone who starts at 300 pounds and diets down to 200.Even years after losing weight, our brains may still be trying to get us to regain the weight, preserving calories and making us hungrier. That’s why so many dieters gain weight in the end.

Because no comparable brain process keeps us from adding walks and veggies to our lives, most will find those things much easier than permanently losing substantial amounts of weight.

(I want to emphasize to readers, again, that no one’s obligated to maximize their health. And not everyone has the opportunity, unfortunately. A rare thing Helen and I agree on!)

It’s irrelevant to discuss if fat people should lose weight, when there’s no reliable way to make that happen.

You called me a defeatist, but I’m not. Knowing that fat people can be happy and healthy and lead great lives is the polar opposite of defeatism.

Imagine two people in a smelly mud pit behind a wall. On the other side of the wall, a beautiful park. The first says “with enough effort, I can vault this wall like Jackie Chan and be happy on the other side.”And so she tries and tries, always failing, while denying there’s any other way to reach the park.

The second realizes she’s unlikely to ever vault like Jackie Chan. So she walks around the wall instead, and is happy in the park on the other side.

Is the second person the defeatist?

I’m out of space – and there’s so much left unaddressed! Let me know if I skipped anything you especially wanted addressed, and I’ll try to fit it in my next letter.

Hoping this finds you safe and happy,


[*] I’m using “works” as shorthand for “significant, sustained weight loss for most people.”

Dear Barry,

OK, fair enough. I could have phrased that better so it was clear I didn’t mean that they weren’t doing that but that they weren’t sticking to that.

Not a single weight-loss model – including long term approaches – has ever been shown to work in a peer-reviewed controlled clinical study.

I think it means that people who went on short-term diets did not succeed in keeping the weight off afterwards. It simply isn’t possible that people ate fewer calories than they burned and got fat or that got slim and then ate the same number of calories that they burned and got fat. Fat needs to be built or maintained with calories. If it were really true, we’d see evidence of it in areas where food is scarce. There’d be a number of thin people and some who were obese saying “I don’t understand it. I barely eat a thing.”

Anyone with a method scientifically proven to really, permanently work would become a billionaire.

What’s the method that explains why most people aren’t fat? Why aren’t I fat when I eat 2000 calories a day but get fat when I start eating more than that? Surely, the thing that isn’t working is people finding a way they can stick to? That’s not a judgemental thing. I’m not actually a believer in free will. I don’t think people who find they can’t stick to the number of calories they need are lazy or undisciplined. I think it’s really hard for them and medical research should look into making it easier.

Weight-loss advocates deny this reality – a finding that’s been in scholarly papers for decades and is unchanged today.

The first study here talks a lot about how severe the psychological effects of feeling deprived can be and refers to this as being undernourished. However, it clearly says that if people stick to this, it works. “A small minority of patients, able to endure the hunger and emotional hardship of treatment and to sustain their undernutrition for years of maintenance, feel that the sacrifices have been worth the effort.”

The second one clearly says that people gain weight again due to a number of factors and then it says,”Those individuals who do sustain substantial weight loss over time generally must maintain high levels of dietary restraint, physical activity, and self-monitoring behaviors.”  Of course.

The third one looks at obesity as a psychological issue but clearly says that the problem is that weight loss programmes are short-term .  “Weight loss ads and commercials bombard the media, including social media, with diets and other products claiming to result in large amounts of weight loss. There is little focus on long-term maintenance.” Later, it refers to the regaining of weight as ‘recidivism’ which clearly indicates that people have ceased sticking to a diet that will enable them to keep the weight off.

In summary, all three of these papers  acknowledge that when patients do stick to a diet programme long-term, they stay slim long-term. However, nearly all of them find this too difficult and revert to overeating.  They all recommend other measures to minimise the impact of obesity on health than sustaining weight loss which indicates that obesity is a problem for health. There is much to be said for these arguments especially if faced with the realistic option between working with what we’ve got – obesity with health risks minimised – or nagging people to stay on a diet forever when they do not feel they can. The papers also provide some useful information about how yo-yo dieting can affect metabolism and the physiological effects of weightloss which can often function to make weight loss harder so there are some physiological causes of weight plateaus and losing weight becoming harder after some has been lost.

You acknowledge some of the physiological symptoms when you say,

Even years after losing weight, our brains may still be trying to get us to regain the weight, preserving calories and making us hungrier. That’s why so many dieters gain weight in the end.

And you make a plausible argument that doing various things for living a healthier lifestyle could be easier for many people than eating less. It isn’t for me. I have managed to lose weight and keep it off all the times I have not been taking centrally-acting medication but have never been able to give up nicotine, wine or chocolate. Of course, this may indicate that I do not have the same problems that many obese people have.

I think the difference of opinion we are having here is between my view that weight loss and maintenance is physically possible but psychologically hard and so the solution must be psychological. I want more effort going into looking at it psychologically. And environmentally.  I still think research into why there was so much less obesity in our grandparents’ generation and trying to recreate that would be worthwhile. I am not ready to settle for being obese. I have been slim for most of my life and it is so much more comfortable and makes doing almost anything so much easier.

You, on the other hand, think there is a need for acceptance and mitigation of health risks, not because you are being defeatist, but because you’d rather spend your life that way than to keep trying and, statistically, being very likely to keep failing to lose weight. I think that is a perfectly reasonable analysis of the situation and decision to come to. When I say I want more focus on the individual’s psychology in order to find personalised solutions and not rely on formulaic programmes which work physically but not psychologically, I think some people’s psychology might reveal that they want to do what you want to do.

Dear Helen,

Of course if someone eats little enough, they will lose weight. And if they keep eating little enough forever – which may require eating even less than when the diet began, as their body attempts to regain the weight – they can keep the weight off.

In this extremely superficial sense, it’s true that all fat people can diet their way to no longer being fat.

But that’s sidestepping the real question: Can a typical human voluntarily reduce food intake enough to cause a large loss of weight, not just for a few months or years, but for a lifetime? Not just in theory, but in practice? Study after study has shown that the overwhelming majority of us cannot.

You don’t deny that this is the case (thank you!), and say medicine should work on changing this. But it’s been working on it, for longer than we’ve been alive, without success. And in the meantime, trying and failing to lose weight (including in the form of multiple weight losses and regains) is harming many people’s mental and physical health.

Unless something in the science changes, the large majority of fat people will never be able to deliberately lose enough weight to stop being fat – and most weight lost, will eventually be regained.

That’s one thing “fat acceptance” means – just accepting that fact.

If there’s one thing I’d like people to take away from what I’ve written here, it’s this: It’s useless to say “fat people should stop being fat” when there’s no pragmatic, safe, and sustainable way to make that actually happen for most fat people.

Since this is my final letter in our exchange, I thought I’d finish up by listing some changes this fat activist wants to happen.

1) I want every fat person to choose for themselves if they want to try dieting their way out of being fat – but without being pressured.

2) But I also want fat people to have full and truthful information before deciding. They should know that – for those fat people who want to work on their health (and not everyone does, or should be expected to) – simple techniques like eating more vegetables and moderate exercise have been proven enormously beneficial, and this is true even if they remain fat.

They should know that the overwhelming majority of fat dieters don’t lose enough weight to stop being fat, and often end up fatter than when they began. They should know that multiple cycles of weight loss and regain are harmful physically and, for many, mentally – and are a far more likely outcome than permanent weight loss. They should know that it’s the body’s natural defenses against weight loss – not being weak-willed or contemptible – that make it effectively impossible for most people to keep large amounts of weight off.

3) Direct anti-fat discrimination and exclusion – from employers and doctors and teachers and engineers and clothing designers and so many others – has to stop.

4) Anti-fat stigma should stop as well, as much as possible. If we’re genuinely concerned about fat people’s health, then this should be a no-brainer; the damage to health from being stigmatized is fairly well documented.

What would ending anti-fat stigma look like? A full answer to that question would require thousands more words. But we could begin by changing the way our major institutions (such as schools, children’s books, television and movies) depict fat people. Ordinary fat people leading ordinary lives would ideally be as common on TV shows as we are in life, while anti-fat stereotypes become much rarer. (To be clear, I’m talking about creating these changes through persuasion and consumer advocacy, not any form of censorship).

5) Probably the hardest part: As a society, we have to stop teaching fat people to loathe ourselves.

Which I think begins with fat acceptance. In fact, all these changes are part of fat acceptance.

Thank you for this exchange. And in particular, thank you for how you’ve engaged this topic with me. It’s been difficult to find anyone who will disagree with me about fat acceptance politely and thoughtfully; abuse and contempt are more common. (Which is, I suspect, one reason most pro-fat people hesitate to get in these discussions.)

In our exchange, you’ve mentioned your own plans to stop being fat. I genuinely wish you nothing but success with that. But whether or not you succeed, I wish you happiness.

Best wishes, Barry

    Corso says:

    It’s an interesting subject… One thing I’d suggest if people wanted to try losing weight without a lifestyle change is moving out of America.

    That was only mostly tongue-in-cheek. A significant amount of my friends who I grew up with in Europe and immigrated to the states believe, independently of each other, that your food supply is particularly unhealthy; Many of them did not change their eating habits, but gained serious amounts of weight very quickly.

    Some of that could do with aging and not wanting to admit it, but if you’ll allow me to indulge in some tinfoil hattery, perhaps the FDA bears some responsibility for allowing corn sugar to be put into almost literally everything you eat? I’ve been on vacation to the states a few times, and your food tastes different. It’s amazing how different a can of Dr. Pepper, squirt of Heinz ketchup, or jar of Prego pasta sauce tastes.

    Ampersand says:

    Corso, do you mind saying what country you live in? (Sorry if I’ve asked before and forgotten.)

    I’m very leery of magic-bullet explanations of increasing fatness. Many people have the exact same theory about corn syrup, but even though it’s been studied a lot and laws have been proposed, the evidence seems weak (see here and here, for example).

    Another thing to keep in mind is that, although folks in the US are fatter on average, increasing fatness is basically a worldwide phenomenon – including in Europe.

    Canada right now, but I was born in France and spent a lot of time in the UK.

    I’m very leery of magic-bullet explanations of increasing fatness.

    Fair. This was more my anecdotal experience than anything concrete, your mileage may vary, and I’d be equally skeptical of anyone saying they found a single thing to “cure” obesity. My point was more that I think your food chain works against you on that front.

    I also think that there might be a cultural issue working against you… I’ve been to Vegas, New York, and Austin, and maybe that’s not the most representative sample, but my impression is that your portion sizes in restaurants are *huge*. I never finished my plate and I felt like an asshole afterwards.

    Lauren says:

    Thanks for the link!

    Another thing to keep in mind is that, although folks in the US are fatter on average, increasing fatness is basically a worldwide phenomenon — including in Europe.

    Based on all the wailing and teeth gnashing people over here (Germany) are doing about the horrible obesity thread, definitely.

    Also, interesting that that graph exposes the lie often spouted against fat-acceptance that a “Mediterranean diet! is so much healthier!” – since Spain, Italy and Greece are right up there.

    The most convincing explanation I have heard for the fact that in general, on a global scale, so-called first-world-people seem to be getting fatter is that the human body evolved to deal with a world of scarcity. The more easily available food is, the less those survival mechanisms are actually necessary – but evolution being a slow process means those are not likely to change any time soon, so energy storage in fat for leaner times that end up not actually happening continues.

    But while that explanation might work to understand a global development, it still doesn’t explain why some individual people do and others do not get fat.

    I was – going by the very bad BMI-standard – underweight through my teens and early adulthood. Once I was done with university and started office work, I started gaining weight steadily. I would now probably classify as overweight, though not “fat” in the sense of deposits.

    What changed? You might blame less physical activity – driving the long commute to work instead of biking to uni. Also, simply getting older. My eating habits haven’t noticeably changed, so that wouldn’t really explain it. The biggest change? Going on anti-depressants. And while the increase of weight with those – as well as anti-psychotics – is a well-known phenomenon, the other effect is a very much lowered level of constant stress. Since I have been dealing with clinical depression since I was a preteen, my “old” body was constantly suffering under that stress. So maybe the reduction of that lead to weight gain? At the same time, there is a lot of writing out there connecting weight gain to higher levels of stress. So maybe how the body is affected by stress regarding weight varies from person to person.

    I don’t have the answers. I just know that while pretty much everybody accepts the explanation that somebody is just naturally thin, usually calling them lucky, nobody ever seems to agree that it must then also be possible to be naturally overweight/ fat.

    I also know that living in a fat-hating culture has made it really hard for me to deal with the changes in my body, despite the fact that I had learned about HAES and fat acceptance long before I started to gain weight. Theoretical agreement is a lot easier than applying those lessons to yourself.

    Considering how many people stop taking very important medication specifically to end the associated weight gain, this is just another way that the focus on weight and the false equation of thinness with health, beauty and worth can quite literally destroy peoples lives. If you have ever dealt with a paranoid schizophrenic who went of their meds suddenly and without medical guidance, as I do regularly at work, you know what I mean. I am not going to say that removing the stigma of fatness would solve the problem of what they call non-compliance, since there are often other side effects, but it could certainly help.

    Dianne says:

    If there’s anything about life in the US and in the world in general right now that is causing weight gain, my hypothesis (I don’t have proof of it, but do have some rationale) is that it’s not corn syrup but three other factors that are primarily related to obesity:

    1. Stress. A lot of people are under excess stress right now. Ask anyone in the UK how they’re feeling. Probably hot and stressed (both physically and psychologically). Stress leads to excess cortisol, which leads to weight gain, even assuming perfect self control and no stress eating.
    2. Lack of sleep. There is some evidence (I can try to dig up if anyone’s interested) that lack of sleep leads to weight gain, probably due to the above. There is a lot of propaganda around the need to work more and anyone who is poor (or even just less than rich) while working less than 100+ hours/week is shamed. This doesn’t lead to good sleep habits. There are 168 hours in a week. If you work 110 hours/week, you literally cannot sleep as much as the average person needs to.
    3. Poverty. See stress and lack of sleep, above, for two probable mechanisms of action. Also, calorie dense food tends to be cheap and easy to prepare. And that’s not even taking into account the food desert problem.

    In short, want to reduce obesity? Reduce poverty and social inequality. Reduce climate change and related weather stress. Improve public transportation and walkability/bikeability so people don’t have to use cars. (Also see Barry’s cartoon on the housing crisis in regards to this.) It may or may not make the average person thinner, but it’ll make them healthier, possibly happier, and increase their life expectancy and those strike me as better goals than making them thin.

    “Mediterranean diet! is so much healthier!”

    The whole ‘Mediterranean diet’ thing is based on a parody of the Mediterranean as seen through the eyes of northern Europeans. Jamie Oliver (a big perpetrator of this) doesn’t seem to realise that of the 50 million Italians/Spaniards, only a relatively small number are crinkly-faced charming old paisanos living in adobe houses and baking their own bread every day.

    I know this is a side note, but it hits home for me – I live in Barcelona, the biggest city in the northwest Mediterrannean, and roughly 0.0001% of people eat the so-called “Mediterranean diet” here.

    I’m sort of agnostic on the question of why people are getting fatter – I’m much more focused on what to do since fat people are here, and very likely we’re here to stay. :-p

    My interest in the question is mostly based in the desire to get away from the “they are all gluttons without any will to overcome their obsession with food” – framing that is far too widespread, as well as the lie that “simply loose weight” is good health advice instead of snake iol peddling.

    That said, while the goal to get rid of fattness (and btw., how often do they pretend that this is a worthy, nay laudable goal, when the fact that so many people will never stop being fat means that the only way to fulfill it would be to “get rid of” fat people?) is not one I agree with, I would be interested in understanding the scietific explanations.

    One, because I just like knowing things, and two because a better understanding on why some people are naturally thin and others are naturally fat might lead to treatments for health issues that correlate with being extremely underweight or extremely overweight. Maybe we could get better at preventing dangerous weight loss due to medical treatments or illness, or reduce weight gain as a side effect of medication. Basically, just as the general HAES approach today, see how that knowledge could be used to improve health outcomes for people who want that improvement, instead of focussing on looks – to the detriment of a lot of people of all sizes, since the faulty assumption of thin=healthy can lead to health problems for thin people, too.

    Your reason for being interested makes total sense to me! I hope I didn’t sound like I was criticizing you for having an interest; that wasn’t my intent. :-)

    This all reminds me of a joke (?) about how weight loss dieting would be received if it were a drug:

    Pharma rep: We have this great new drug for obesity. It’s called weight loss dieting (WLD).

    Doctor: I have a lot of obese patients who are unhappy with their weight. Tell me more.

    PR: Twenty percent of people who took WLD experienced weight loss averaging 5-10 pounds*.

    D: Not great, but more than none. So what are the potential downsides?

    PR: Well, only a minority of people continued taking WLD.

    D: Why?

    PR: It tends to make people feel constantly hungry even after eating excessively at a single sitting.

    D: So it blows out the satiety centers?

    PR: No, no. Nothing so drastic. It just renders them inoperable. Temporarily.

    D: Oh, okay. How long does the temporary effect last?

    PR: Until the weight is regained.

    D: Thanks, but no thanks.

    *Numbers approximate based on my memory because I don’t have time to pull the real numbers just now.

    Amp, I looked at those two studies regarding analysis of a possible link between HFCS and the prevalence of obesity. There’s one disconnect between them and Corso’s comment; those studies pretty much concentrate on a link between obesity and use/consumption of HFCS in soft/carbonated drinks. But, as Corso says, HFCS gets put in a LOT of our foodstuffs. Maybe it’s just the overall caloric overload.

    You can tell when there’s Hispanics in the neighborhood when the local grocery store starts stocking Coke bottled in Mexico – it’s made using cane sugar, not HFCS, and the Hispanics swear it tastes different. I haven’t tried it myself, as years ago I swore off soda and other such drinks. I pretty much only drink water and whiskey myself. My beer intake isn’t even all that significant.

    I’m not Hispanic, and I’ve never tried coke bottled in Mexico, but European coke also uses sugar and I can very easily tell it apart from US coke by taste. It’s my understanding that there isn’t much of a difference in the effect on the body between HFCS coke and sugar coke, but I haven’t read any actual studies on the matter, just some nutrition advice I was given by my doctor, so I don’t know how trustworthy that is.

    Yep. You can easily tell in a blind taste test cane sugar vs hfcs coke. It’s just a very different kind of sweet.

    Passover observing Ashkenazic Jews also drink cane sugar coke instead of hfcs coke during the holiday. I know many who would stock up on extra kosher for Passover coke because they prefer the taste of the cane sugar version. I know I do, but I don’t drink enough soda to keep it in the house.

    This is late compared to the majority of the comments but I want to put my 2¢ in. I think it’s a mixture of factors. Science may be inconclusive on sugar vs corn syrup at the moment but there is sugar or sweetener of some variety added to way more stuff now (one of the reasons processed foods are discouraged). I have a heck of a time finding things like peanut butter, dried blueberries, and another items that don’t need sugar for sale without added sugar. Regarding the US vs other countries, our cities (except for the big early ones) are not set up to be walkable and even the areas surrounding the big cities no longer generally are structured to walk to train station (or other transit) and commute in. I did also see someone mention US portion sizes which I agree is a factor. One can start to ask for a to-go box at the beginning of the meal which helps but it still requires quite a bit of changing your thinking and habits.

    I do think a large part of it is physical exercise overall. I forget how many years ago but there was a historical reality show (frontier/pioneer family?) on public TV where they were supplied initial food sufficient to make it until crops came in but the wife was frantic because her husband was wasting away. She insisted on a modern medical exam which determined that he was in excellent health AND fit the height/weight charts of that historical era. He was simply using more calories than are necessary in our modern life. Laundry, housework, food preparation and storage, heating, and numerous other daily activities (including many indoor/office jobs without modern conveniences) required way more calories than they do today. You might be able to make up some of that with an hour’s worth of “exercise” but you won’t be able to use all the calories used in a typical day in the 1840s (or whatever period they set it in).
