This episode is a part of “Well being Fairness Heroes,” an editorially unbiased particular challenge that was produced with monetary help from Takeda Prescription drugs.
Rachel Feltman: In line with information from the Facilities for Illness Management and Prevention, at least one in 5 U.S. adults in every state are categorized as, quote, unquote, “dwelling with weight problems.” However for a lot of of these folks, having physicians concentrate on their dimension is way from useful. The truth is, there’s analysis to recommend that our fixation on weight could possibly be stopping us from truly serving to folks dwell wholesome lives.
For Scientific American’s Science Shortly, I’m Rachel Feltman. Immediately we’re speaking a few subject which may sound completely radical to a few of you, however I hope you’ll pay attention with an open thoughts. My visitor at the moment is Ragen Chastain. She’s a speaker, author, researcher and board-certified affected person advocate. Her Substack publication, Weight and Healthcare, meticulous, evidence-based data on, you guessed it, weight and well being care. Immediately she’s right here to speak to us about how weight stigma—in different phrases, a systemic bias towards greater our bodies—might probably be guilty for most of the detrimental well being outcomes we’ve been taught to affiliate with gaining weight.

Feltman: Ragen, thanks a lot for approaching to talk at the moment.
Ragen Chastain: Oh, thanks for having me. I’m so excited.
Feltman: I’m actually excited. I’m an enormous fan of your publication. I discover it tremendous useful, so—actually wanting ahead to chatting about it. However for people who aren’t already conversant in you, how would you describe what it’s you do?
Chastain: Yeah, so my space of experience is on the intersections of weight science, weight stigma and well being care observe. And so I train well being care suppliers about finest practices for working with higher-weight folks. I assist higher-weight folks navigate weight stigma within the well being care sphere, and I analyze and contribute to the physique of analysis round weight-neutral well being and weight science usually.
Feltman: Superior. And I do wish to pause earlier than we go additional simply to speak about, like, phrases we’d find yourself utilizing and phrases we’d not use which may shock some listeners. May you inform me slightly bit in regards to the phrase selections you employ in your publication and the work that you just do?
Chastain: When it comes to language round higher-weight folks, the phrases overweight and obese are phrases that had been actually made up for the specific goal of pathologizing our bodies primarily based on shared dimension reasonably than shared metabolic profile or cardiometabolic standing like we’d see in a typical illness analysis.
And the concept of pathologizing higher-weight our bodies is rooted in and inextricable from racism and anti-Blackness. And I completely urge folks to learn Sabrina Strings’s Fearing the Black Physique and Da’Shaun Harrison’s Stomach of the Beast to be taught extra about how not solely are these items rooted in racism and anti-Blackness however they’re persevering with to disproportionately affect these communities.
Feltman: Completely. Yeah, I actually admire that as a result of I feel numerous actually well-meaning folks and publications and establishments—I imply, in all probability additionally some very not-well-meaning establishments, however a few of them are effectively that means—you recognize, say, oh, we’re going to concentrate on person-first language.
And, you recognize, as a self-identified fats individual, I don’t know any higher-weight one who ever was like, “‘Individual with obese’—that’s what makes me really feel good.”
Chastain: As if weight stigma would not give me sufficient issues, let’s make me grammatically problematic as effectively. Yeah, the factor about person-first language is that it’s being marketed as antistigma language, but it surely didn’t come from weight-neutral well being neighborhood, health-at-every-size neighborhood, fats activism.
It got here straight from the burden loss business as a part of their marketing campaign to have merely current in a higher-weight physique, once more, no matter precise well being standing, be seen as a persistent, lifelong situation that requires persistent, lifelong therapy from them. And so it’s being pushed by, quote, unquote, “affected person advocacy teams” that they fund.
That is person-first language for higher-weight folks. Initially, they co-opted it from incapacity neighborhood, the place there’s numerous dialog and transformation and nuance. And once more, urge folks to take heed to people from that neighborhood to grasp these nuances. However absent these nuances, the weight-loss business form of took it and plopped it onto higher-weight folks.
And the, the issue is, to me, it’s extra stigmatizing as a result of we do not speak about different our bodies that manner. I’m not like, “Oh, I hope my pal with tallness can come over so I can change that gentle bulb,” or, “I feel that man affected by thinness on the bus—I imagine I do know him.” That’s not how we speak about our bodies.
And so after we recommend that it’s so stigmatizing to easily precisely describe a higher-weight or fats physique that we’d like a semantic workaround, that really creates stigma. It doesn’t scale back it.
Feltman: Yeah, I feel that’s very well put. Nicely, and it is a nice segue as a result of I feel a few of our listeners in all probability assume that it’s widespread sense that being in an even bigger physique brings all kinds of well being dangers. However after all now many researchers are pushing again on that. So might you stroll us by what the info truly says about larger weights and what it doesn’t say?
Chastain: Positive. So it—I’ve been learning this analysis for 20 years, and I got here to it believing precisely what you’re saying, proper, believing being higher-weight is a wholesome situation and weight reduction is the answer to it. And in digging into the analysis, I discovered that neither of these issues had been truly what the analysis was saying. And so what occurs is we get this analysis that correlates being higher-weight to a well being situation and, you recognize, so your first day of analysis strategies class, they train you correlation will not be causation, proper?
You may’t assume one factor causes the opposite as a result of they occur collectively on the identical time. And this will get tough in medical analysis as a result of we use correlation on a regular basis, but it surely’s not accountable to try this with out investigating what are referred to as confounding variables, proper? Principally, what else occurs to higher-weight folks that would result in larger charges of those well being points?
And by way of the analysis, there are three well-researched confounding variables: weight stigma, weight biking, or yo-yo weight-reduction plan, and well being care inequalities. And these items independently are correlated to the identical well being points that get blamed on physique weight. And in these research, they’re not often even talked about and by no means managed for.
And so after we speak about, you recognize, quote, unquote, “weight-related” or, quote, unquote, “obesity-related” circumstances, what we could be truly speaking about are weight-stigma-related circumstances, weight-cycling-related circumstances and health-care-inequality-related circumstances. For instance, [Linda] Bacon and [Lucy] Aphramor [noted research that] discovered that weight biking might account for the entire extra mortality that was attributed to, quote, unquote, “weight problems” in each [the] Framingham [Heart Study] and the NHANES [National Health and Nutrition Examination Survey].
And so we’re speaking about severe confounders that aren’t being explored in any respect within the analysis. And, you recognize, an enormous a part of that, from my perspective, is that the analysis is usually being carried out and funded by the weight-loss business. And I’ve form of developed over time a little bit of a subspecialty within the ways in which the weight-loss business has and continues to infiltrate and manipulate the well being care business.
And this analysis is a kind of methods.
Feltman: Yeah, effectively, I positively wish to get extra into that as a result of I feel you do some actually unbelievable work in that area. However for people who’re, like, possibly having their minds blown proper now, you recognize, what will we find out about the place this conflation comes from? I do know that you just already talked about some beneficial studying on the origin of weight stigma, however I might love to listen to slightly bit extra about that.
Chastain: Yeah. So, and I wish to say, too, for those who’re listening to this and also you’re having, like, anger, denial, defensiveness, incredulousness, I’ve had all of these emotions within the final 20 years as I’ve been researching this. So I wish to identify that as legitimate and say, if you do have these emotions, I simply provide that as an invite to dig deeper and ask extra questions.
However by way of weight stigma, so the analysis on weight stigma reveals that the expertise of weight stigma and even perceived weight stigma is correlated independently with issues like larger charges of kind 2 diabetes, larger charges of hypertension, suicidality, substance use, decrease health-related quality-of-life scores, virtually 60 p.c better danger of total mortality—so we’re speaking about severe correlations right here between experiencing weight stigma and these well being dangers and points that find yourself getting attributed to weight.
Feltman: And what will we find out about, you recognize, how this impacts, form of public well being total?
Chastain: So sooner or later, public well being turned much less about serving to the general public be wholesome and extra about making fats folks’s our bodies the general public’s enterprise, with the purpose of eradicating higher-weight folks and ensuring no extra ever exist, proper—the, quote, unquote, “therapy” and “prevention” of, quote, unquote, “weight problems.”
And it’s useful, I feel, to substitute higher-weight folks current for the time period weight problems to get a transparent image of how this impacts higher-weight folks in public well being. And I do not assume most individuals had been doing this from an ill-intentioned perspective, proper, however what we ended up with is public well being that’s hyperfocused on eradicating higher-weight folks and stopping higher-weight folks from current in ways in which find yourself harming higher-weight folks and make it virtually unimaginable to help the well being of higher-weight folks straight.
And also you get a co-opting and twisting of the idea of anti-weight stigma that finally ends up like, “We don’t wish to deal with fats folks badly, however we positively wish to rid the Earth of them and ensure no extra ever exist however, you recognize, like, in a nonstigmatizing manner,” and that’s not truly attainable.
And so, by public well being, this concentrate on, this hyperfocus on manipulating physique dimension reasonably than an evidence-based choice to help folks’s well being primarily based on their very own priorities and definitions on the dimension that they’re has ended up making a public well being system that’s hostile and dangerous to higher-weight folks.
Feltman: Yeah, completely. Nicely, and I feel once more, for our listeners who’re, you recognize, possibly very new to this, let’s speak about a number of the ways in which, you recognize, form of, um, health-based interventions may be decoupled from, you recognize, weight-loss and weight-based interventions and form of the sorts of well being care that folks have issue accessing or [are] even outright denied as a result of they’re in a higher-weight physique.
Chastain: Yeah, that’s an enormous, like, space of concern. So there’s numerous ways in which this occurs. There’s implicit and express bias from well being care suppliers, proper, the place, both subconsciously or consciously, they’ve acquired these stereotypes and preconceived notions about higher-weight folks that cause them to deal with, you recognize, us otherwise—both give us much less time, fewer suggestions, make assumptions about our behaviors.
There’s additionally structural bias. And this occurs when the issues that higher-weight folks want merely do not exist for us within the areas we’re. And that could possibly be something from a chair in a ready room to an MRI machine. And all stigma requires systemic options, however structural bias can solely be solved systemically.
As a result of you’ll be able to have a totally fat-affirming supplier, a totally fat-affirming affected person, but when the MRI is just too small, that affected person can’t get care. And so, inside the well being care system, these are all points that face higher-weight folks each day.
There’s additionally, as you talked about, accessing well being care. In order a affected person advocate, typically what I’m engaged on, and as a researcher and author, is the concept of BMI-based well being care denials. And that is when an individual is refused a well being care process {that a} thinner individual would get except or till they turn out to be a sure BMI or they lose a specific amount of weight.
And that is holding well being care hostage for a weight-loss ransom that almost all sufferers aren’t in a position to pay. And it could form of float into the ridiculous, the place—I had a affected person who was denied the gender-affirming care that they wished however then was referred to weight-loss surgical procedure. And that’s an truly a reasonably widespread factor, and on this case, I don’t anticipate this to ever work once more, however the argument we made was, you recognize, you’re saying that you just’re denying this surgical procedure due to anesthesia danger, however you’re now going to supply this affected person weight-loss surgical procedure. Whoever’s going to do the anesthesia for the burden loss surgical procedure, might they only, like, come down the corridor and do the surgical procedure this affected person truly desires and wishes?
And so they ended up agreeing, however I’m unsure that can ever work once more. However, like, that is the place we’re at by way of well being look after higher-weight folks—that it may be a struggle simply to entry primary care. After which the opposite piece of that’s what I name supplier weight distraction, the place the supplier turns into so hyperfocused on the affected person’s weight and manipulating the affected person’s dimension that they’re not listening or responding to the affected person’s precise criticism presentation, why they’re there, what they need in well being care.
And so this could actually result in sufferers who disengage from care or sufferers who merely can’t entry the care that they need and want.
Feltman: And the way do you assume that medication like Ozempic are impacting this, you recognize, weight-centric well being paradigm? After which, you recognize, how is weight stigma impacting the best way that we speak about these medication?
Chastain: Positive, I, now, I take a really agency view of bodily autonomy. Proper? So I feel folks can do what they need. However I feel folks deserve good data, and by way of well being care, they deserve moral, clear, knowledgeable consent.
Feltman: Mm.
Chastain: I’ve performed breakdowns of the analysis on these weight-loss medication since they began, and I’m not practically as excited because the people who find themselves studying the advertising language versus the analysis.
For instance, uh, Wegovy, or semaglutide, Novo Nordisk’s drug, their four-year outcomes have simply come out, and so they claimed that folks had been in a position to preserve 10 p.c loss. However for those who look, they began with virtually 9,000 folks, and so they ended with solely 900 in 4 years. In order that’s large attrition that didn’t make the headlines, proper?
So I feel these are—to begin with, I wish to be clear, these are strong kind 2 diabetes medication.
Feltman: Completely.
Chastain: Proper. They work effectively for people who find themselves contraindicated on different medication. They work effectively for individuals who couldn’t get the glycemic administration they wished on different medication. and so they have advantages by way of solely working when blood sugar goes excessive, so there are fewer hypoglycemic episodes.
However so what occurred was they realized that these medication had a small facet impact of weight reduction. And so what the drug corporations requested was, “Nicely, if we gave folks megadoses of those kind 2 diabetes medication, would that enhance the burden loss?” And so they came upon that sure, it will, and that’s how these flip into, quote, unquote, “weight-loss medication.” And so there’s an enormous titration distinction as a result of with kind 2 diabetes, the purpose is to provide the smallest dose crucial to realize the glycemic management that any individual desires and scale back or reduce unwanted side effects. However with weight reduction, they’re simply attempting to get folks to take as a lot as they will for the specific goal of maximizing unwanted side effects.
And these medication have severe, generally deadly unwanted side effects, and in order that’s not a small situation.
Feltman: Proper. And the way are you seeing the prevalence of those medication, you recognize, with the purpose of weight reduction, affect the best way mainstream physicians speak about and deal with higher-weight sufferers?
Chastain: Yeah, so, and form of to proceed out of your different query about how weight stigma is concerned, it’s vital to grasp that the approval of those medication by the FDA was primarily based on a risk-benefit evaluation that means that it’s value harming or killing some higher-weight folks to make others a bit thinner.
And that’s a view that’s primarily based in weight stigma, proper, typically to treatment or forestall well being points that skinny folks additionally get however from whom these dangers aren’t requested. So there’s that piece of it, and the weight-loss business, and particularly the pharmaceutical corporations who make these medication, are actually falling throughout themselves to say, “Oh yeah, behavior-based weight reduction interventions don’t work long-term.”
Proper? And so they’re, like, the final 15 folks to determine this out. We’ve been, folks have been screaming this from the rooftops in my neighborhood since earlier than I used to be born, proper, that at this level, 100 years of analysis present that just about everybody will shed pounds short-term and acquire it again long-term as a result of these behavior-based interventions physiologically change our our bodies, making them into form of weight-regaining, weight-maintaining machines.
And so now medical doctors are form of being trustworthy with themselves about this, proper, as a result of that is what they’d, so they might simply inform each higher-weight one who got here in, like, “Eat much less and train extra,” with out sometimes asking even what we ate or how a lot we exercised. And now they’re saying, “Oh, effectively, now there’s a drug, so, like, it’s a lot simpler, and also you simply get on the drug.”
And I’m listening to sufferers who’re actually being pressured to take the drug and/or who’re saying, “These unwanted side effects are insupportable to me” and are being pushed to tolerate them.
Feltman: Wow. Yeah.
Chastain: Proper? And being given an unclear image of the probability of long-term success. The form of best-case situation is that at 65 weeks, folks may have misplaced form of no matter they’re going to lose.
And in the event that they go off the drug, the entire analysis reveals they’re going to realize the burden again and lose the cardiometabolic advantages that they acquired. And so that is, mainly they’ve invented each weight-loss drug that ever existed. That is how weight-loss medication work. However their advertising is that, oh, effectively, once more, due to this concept that, quote, “weight problems” is a, quote, “persistent situation,” you simply need to take these medication for the remainder of your life.
Now, their analysis doesn’t help that it will work. In tirzepatide’s research, 10.5 p.c of people that stayed on the drug had gained again 20 p.c of the burden simply in a single 12 months. So we don’t know that that’s even gonna work. Proper? However that’s the messaging. And so I feel medical doctors are getting a view of this that’s vastly overstating the analysis.
And that’s as a result of numerous the communication is coming from the businesses themselves, who even have taken extremely lively roles in creating and working the analysis. Um, and once more, in doing the breakdowns for these, they’ve strayed so removed from what could be thought-about acceptable best-practice analysis strategies and statistics to be able to get these outcomes that they’re publicizing. And so I feel that it’s placing medical doctors at a drawback as a result of they’re being misinformed, after which they’re misinforming their sufferers. And there’s simply, once more, a lot concentrate on the concept of constructing fats folks skinny reasonably than supporting their well being straight that medical doctors and generally sufferers really feel like “it’s value risking my life and high quality of life for this.” And that is also about not simply well being however escaping weight stigma, which is one other piece of this, proper: that we’re attempting to vary ourselves to swimsuit our oppressors in order that we may be handled higher.
And whereas people could make that call, as a society, to say it’s best to change your self to swimsuit those that, you recognize, oppress and bully and hurt you is a harmful, harmful highway to go on.
Feltman: Yeah, completely. You recognize I feel it’s so attention-grabbing how little medication is anticipated to innovate to be higher at, say, performing surgical procedure on an individual at a better weight, you recognize, versus having these BMI necessities for generally extraordinarily crucial surgical procedure.
And as a science journalist, I’m additionally simply so struck by, like, the credulity I see in folks speaking about this class of medicine.
The whole lot I discovered in, you recognize, science journalism grad faculty tells me to be extraordinarily skeptical of, like, these, quote, unquote, “miraculous” medication, you recognize, within the phrases of the businesses promoting them. And it simply feels weird to see not all however numerous the media treating these medication, like, fully otherwise than they might some other class of medicine.
Chastain: Yeah, that’s such an vital perspective, and it has been actually irritating to me. Issues just like the New York Occasions—there was an article by Gina Kolata … that each single professional quoted had taken cash from the drug producers.
And there was no disclosure of that.
Proper? I’m seeing numerous that, and, for instance, there was a research that appeared on the impact of Wegovy (semaglutide), Novo Nordisk’s drug, on main adversarial cardiac occasions. And as a substitute of releasing the research, Novo Nordisk launched a press launch saying that it had been a 20 p.c discount [in relative risk] in adults with, quote, unquote, “obese” and, quote, unquote, “weight problems.”
And that unfold like wildfire by the worldwide media. Novo Nordisk’s inventory went up by 17 p.c that day. However when the research got here out, what we discovered was truly a 1.5 p.c discount [in absolute risk]. The issue is, I don’t wish to put this all on reporters as a result of we’ve acquired a 24-hour information cycle; there are fewer and fewer reporting jobs; individuals who by no means meant to be science reporters are being requested to report on science.
So there’s numerous points that put reporters at a drawback, however I feel it does the general public an amazing disservice when reporting will not be extra crucial in the best way that they take a look at these headlines and these press releases and this analysis.
Feltman: And when you consider a extra equitable well being panorama, significantly almost about physique dimension, what does that appear like, and what wants to vary for us to get there?
Chastain: Yeah. So we have now an excellent physique of analysis that reveals that behaviors are a greater predictor of present and future well being than is weight or weight-loss makes an attempt. And clearly, way more impacts our well being than merely behaviors, proper? However after we’re speaking about “What would a health care provider suggest to a affected person?” there’s an attention-grabbing research on this.
[Traci] Mann, [Britt] Ahlstrom and [A. Janet] Tomiyama checked out this declare that 5 to 10 p.c weight reduction creates clinically significant well being advantages and located in correlational evaluation that they couldn’t correlate the precise weight reduction with the well being points, and so they posited that it was, in truth, the conduct modifications as a substitute.
[Eric] Matheson et al. checked out 4 behaviors. They checked out 5 or extra servings of fruit and veggies a day, exercising greater than 12 instances a month, as much as two drinks a day for cis males and one drink a day for cis ladies and never smoking. And so they discovered that individuals who participated in all 4 of these habits had the identical well being hazard ratio, no matter dimension.
So I feel what we’d like usually is a change in focus that, reasonably than attempting to govern the burden of individuals, that we’re attempting to help their well being straight.
Feltman: I positively suggest that folk go take a look at your publication. We’ll completely hyperlink to it within the present notes. however for those who might give simply, like, one main takeaway to people who aren’t going to go do this, what wouldn’t it be?
Chastain: I simply wish to say that even when I’m incorrect about all the pieces, proper, even when all fats folks might turn out to be skinny, even when by changing into thinner, they might turn out to be more healthy, fats folks would nonetheless deserve the appropriate to exist with out disgrace, stigma, bullying or oppression and would nonetheless deserve the appropriate to finish entry to society, together with well being care.
It doesn’t matter why they’re fats. It doesn’t matter if there are well being impacts of being fats. It doesn’t matter if they might or wish to turn out to be thinner. Fats folks deserve equal rights and entry to the world, once more, together with well being care.
Feltman: Ragen, thanks a lot for approaching to talk at the moment. This has been tremendous informative, and I actually admire your time.
Chastain: Thanks a lot for having me and for speaking about this and for all of the work that you just do. I’m honored to be part of this.
Feltman: That’s all for at the moment’s episode. Take a look at Ragen’s Substack Weight and Healthcare if you wish to be taught extra—like, critically, a lot extra, as a result of she cites all her sources. We’ll be again on Monday with our regular information roundup.
By the best way, we’re nonetheless in search of some voice memos to assist with an upcoming episode. We’ll be having a look on the science behind earworms, these songs you simply can’t get out of your head, and we’d like to function a few of your favourite—or possibly most infuriating—examples. In case you’d wish to share an earworm with us, make a voice memo in your cellphone or laptop and ship it over to ScienceQuickly@sciam.com. And, sure, we do wish to hear you singing, or a minimum of buzzing, the earworm in query. Be sure to inform us your identify and the place you’re calling from, too.
