How to Defy Death

How to Defy Death

Yahoo07-04-2025

Humans have always tried to prolong life and battle mortality, but what do the current influx of biohackers reveal about this era of individual responsibility?
Timothy Caulfield, a professor and the research director at the Health Law Institute at the University of Alberta, studies how health and science are represented in the public sphere. The lines between wellness culture, longevity, and biohacking are beginning to blur, and Caulfield offers advice about how to dodge misinformation and unproven theories while still pursuing a long and meaningful life.

[Music.]
Yasmin Tayag: Hell no. Absolutely not. Of course I want to live, like, a long and healthy and happy life. I would love to live to, like, 90. You know, enjoy the time with my family and friends. But, like, thinking about how tired I am now at 37, I'm like—can you imagine how exhausted you'd be at 100, 150?
Brennan: I don't want to live forever, but I'm really scared of death. I mean, it's kind of the one thing we really don't know anything about, right? And I feel like I want to get to the bottom of everything. I want the answers. And that's one we don't get answers about.
Tayag: Maybe that's why we're so tired.
Brennan: Exhausted. I'm exhausted.
Tayag: I'm Yasmin Tayag, a staff writer with The Atlantic.
Brennan: And I'm Natalie Brennan, producer at The Atlantic.
Tasmin: This is How to Age Up.
[Music.]
Brennan: Yasmin, you've been reporting on science, health, culture, for the last, what—decade?
Tayag: It's been a decade.
Brennan: From your perspective, does this current moment of longevity culture feel different to you, or is this just, you know, humans have always been obsessed with figuring out how to defy death?
Tayag: I would say that we could look at any decade, even any century, and see that there were health trends that were prominent. In the 1700s, people were doing bloodletting: literally cutting open a vein to let a couple ounces of blood out. Because they thought that's how you would get rid of illness in the body and be healthier. And 200 years later, John Harvey Kellogg, the cereal guy—he was basically, like, the TikTok wellness influencer of the time, and he was promoting things like electric-light bathing.
Brennan: What's that?
Tayag: It's lying in a box surrounded by lights. And he said this would cure basically any ailment.
Brennan: I'd give it a try. [Laughter.]
Tayag: Kellogg also pushed things like three-gallon enemas.
Brennan: Whoa.
Tayag: Because he was very into the idea of cleansing your insides and outsides to be healthy. And people loved this stuff. Like, he had this spa where he would offer these treatments, and so many people went.
Brennan: I think one thing that's really interesting to me is: As this wellness culture was becoming quite popularized in the 18th century, it's almost at the same time in which enlightenment is becoming the more dominant theory that's beginning to challenge religion. And so much of wellness culture today—to me—again feels like it is trying to be the central organizing principle in our lives that, you know, maybe religion used to take the place of.
Tayag: You know, I think what religion offers people is a set of instructions for living your life. Yeah. And so if that's not being passed down by God, you gotta find it somewhere else. And maybe the particular flavor of wellness right now tells us a lot about where we are culturally.
Brennan: I think that's right. We have an administration that's looking to prioritize or politicize 'health' as a main tenet of its policy. There's a growing culture of people who are undergoing very extreme measures to live longer.
[Music.]
Tayag: Yeah, and also it seems like every day I'm marketed a different supplement promising to improve me somehow.
Brennan: And I think the big question I have, though, is Improve … what? What are we really trying to address or fix?
And there's this idea that if you're not doing this, there's something wrong with you. Like it's a noble pursuit, right? It's a noble pursuit; it's a righteous movement.
Tayag: So Natalie, that's Timothy Caulfield. He's a professor and the research director at the Health Law Institute at the University of Alberta. He and his research team look at the ways that health and science are represented in the public sphere—from product labels to misinformation and the promotion of unproven theories on social media. And we talked about the ways wellness culture, longevity, and especially biohacking are beginning to blur.
[Music.]
Caulfield: Well, I think that's a term that has taken on different lives, too. You know, when I first started exploring biohacking, it was very much this idea of putting a microchip in your body, or, you know, doing something kind of physical—using technology and merging it with the human body. I think biohacking now has morphed into the idea of … it includes that stuff, but it also includes using some kind of technique or procedure or supplement in order to optimize yourself. And I think in some ways, there has been a pivot from wellness and, you know, the alternative-medicine universe, to the language of longevity. And I think it's been a shift from kind of other ways of knowing, and perhaps culturally different ways to approach health, to the science-y kind of language of longevity. And the reality is: It's all the same noise being repackaged as longevity.
Tayag: So could you give me an example of one or two specific forms of biohacking that have become popular?
Caulfield: The cold plunge now has become really common; you hear influencers talking about [it]. It's very common in the manosphere—that masculine online-influencer space. A cold plunge is a pretty extreme activity, right? And you might be doing it with a community of individuals, right? Which, you know, can make it fun, and make it feel like it has a little bit more validity to it. And look, there are some studies that hint that it might have an impact on your immune system—and these are very preliminary—but the reality is, there is no good evidence to suggest that cold plunges are going to have a dramatic impact on your health. And certainly there's no evidence to suggest it's going to help you live longer. And I think we see that a lot in the biohacking longevity space. Sort of a misrepresentation of the complexity and nuance of the actual relevant research. Supplements are another, I think, really, really common biohacking tool that we're seeing now. And again, the supplement industry is absolutely massive. You know, it's a multibillion-dollar industry that is built on a foundation of very sketchy, questionable science, very, uh, light regulation. And yeah; look, I want to be really careful. Major caveat here: If you go to a science-informed clinician, and they tell you how you have a specific deficiency, that's different from the messaging that is emanating about supplements from the longevity industry. So I think those are two really common examples.
Tayag: I mean, I have to admit: I have given into the cold plunge! I was skeptical going in, but I really enjoyed it! I felt amazing after.
Caulfield: And I don't want to dismiss that, right? If people do find that, you know, invigorating, that's a thing—you know, that's a thing that's not to be dismissed. But the promise here is actual sort of biological change, right, that is going to have a measurable impact on how long you live—and we just don't have good studies to back that up.
Tayag: So what's an example of a biohacking practice that did have evidence behind it, but might still be problematic?
Caulfield: There have been examples of extreme diets. You're probably familiar with the intermittent-fasting trend, right? And that's a fascinating story. There've been interesting animal studies, and even sort of studies with humans that have suggested that it might promote longevity. The problem is, it can also, I think, promote disordered eating, right? Short term, like so many diets, they have helped people lose weight. But it's hard to maintain an extreme diet—there's really strong evidence to support this. The best diet, okay, is the diet that's healthy, sustainable, and works for you. That's the best diet, right? A healthy diet is one that is healthy, sustainable, and works for you. And that often means something that you enjoy.
[Music.]
Brennan: I have to admit, I love a cold plunge.
Tayag: [Laughter.] Really?
Brennan: I love a cold plunge. I guess what I mean is: I love to jump into cold water.
Tayag: Where do you do this?
Brennan: Anywhere I could jump into cold. If I could jump in the East River, I'd be swimming in it.
Tayag: Please never do that.
Brennan: I will never do that. On New Year's Day this year, I was at my best friend's house in L.A., and her parents have a pool. And it was filled, even though it was January. It's not heated. And I was like, 'It's New Year's Day; I need to cleanse.' And we jumped in together. And it was the just sweetest moment of my year so far, honestly. I felt amazing for the rest of the day. I can appreciate a lot of the factors there are just: I'm with my best friend, and it's a special day. And as somebody who spends a ton of time in my own head, water is a thing that really brings me into my body.
Tayag: Yeah, and the jolt of cold shocks all the thoughts out of you.
Brennan: But I'm interested in this idea about the placebo effect. In 1955, a researcher named Henry Beecher published an influential paper called 'The Powerful Placebo,' and its findings were debated for decades. But now there's wider scientific consensus that the placebo effect is real.
So, in a classic placebo-effect trial, the control group wouldn't know that they're the control group, right? So let's say one group is given a real medication, and the other is given a placebo pill, and neither group knows which trial they're a part of.
But, there was a study by Harvard Medical School that found that the placebo effect was up to 50 percent as effective as real drugs.
Tayag: Big.
Brennan: Huge. And they tested by giving one group a migraine drug labeled with the drug's name.
Tayag: Mmhmm.
Brennan: And another group took a placebo that was labeled placebo.
Tayag: Oh, they knew.
Brennan: They knew they were getting the placebo. Which may indicate that knowing you're being subject to a placebo doesn't ruin the effects. Which is all to say, to all listeners who are worried that we just ruined cold plunges for them: enjoy.
Tayag: Yeah, you know: If you believe it's gonna make you feel awesome, it will! Maybe it will.
Brennan: It maybe will.
Tayag: But I think, you know, what I would like to see is to reframe these practices. If you love being at your friend's house and jumping into a cold pool on New Year's Day, like—do that, absolutely. But don't believe that it's going to make you live longer or be healthier. It might make you happier. It might make you happier, and, you know, that's important too.
Brennan: Doing things that make you happy, be in community, create joy are good for your health, right? But the promise that we're being sold—that all of these very specific practices are the key to living longer? That one we need to analyze a bit.
[Music.]
Tayag: Tim, we've been talking a lot about how biohacks are promoted as science-based even when they aren't necessarily. So I'm curious: What is the larger impact that has on the public understanding of science more broadly?
Caulfield: We've actually done a lot of research on this. I call it science-ploitation. So, you take real science—exciting science, often—science that has gotten a lot of attention in the popular press and in the information environment more broadly. And you take the language of that science in order to push misinformation or questionable therapies. One of the best examples of that: the stem-cell space. I've worked in this space right from the beginning, from the late '90s forward. I've been very closely connected to the stem-cell-research community. It is a genuinely exciting area of research, and there was a moment when it was the most … like, it was 'headlines' kind of research field. It was controversial because it involved embryo research. And because of that, we got a lot of hyped language about the value and the potential for stem cells to revolutionize health care. That language—and, by the way, that was hype. And probably not justified given how complex science … science is hard, right?
Tayag: Science is hard. Stem cells—I still have to explain stem cells every time I mention them in an article.
Caulfield: It's hard. It remains exciting, right? It remains exciting. But that language, the stem-cell language, has migrated to pop culture, and it's everywhere. The words stem cell: it's on facial cream. It's on beauty products more broadly. It's on shampoo. A bottle might say 'contains apple stem cells' or 'contains organic, all-natural stem cells.' And we know research also tells us that using sciencey language like stem cells does create a veneer of legitimacy. It does make it seem more believable, even if the use of the word doesn't fit with the product. And of course, what's really happening there is they're trying to leverage the genuine and justified excitement about a real field of research in order to give their product a veneer of scientific legitimacy. We've seen it happen with precision medicine. Everything's personalized now. And it works. And holy cow; it really is happening in the longevity space, right? Because these are individuals that want to lean into the cutting edge. They want to lean into things that are sort of in front of the curve. And so, therefore, it makes it more enticing; it makes it seem more legitimate, it makes it seem like they're doing the best they possibly can to live longer. And science-ploitation, as I call it, has become a very, very common marketing ploy. In fact, I think it's almost universal now. If there's a health or a nutritional product, there's almost some degree of science-ploitation associated with it.
Tayag: Well, you know, with science-ploitation so rampant, how is the average consumer—who is maybe not super well-versed in how to assess the value of a study—you know, how are they supposed to make sense of all of this? If you see a face cream that says 'stem cells will renew your skin,' how do you know if that's real or not?
Caulfield: Assume nothing works. I once pitched a book called Nothing Works. And the editors were like, 'Okay, that's a little dark,' but you can almost do that. If there was some kind of revolutionary new approach to doing something, I promise, we would know. There would just be this broad acceptance of it, right? And for most of the things that we want to improve our life, you know: We know the answer. There really are very few, if any, magical answers.
Tayag: Let's remind people what works. What are those things that we should know and not take for granted?
Caulfield: You don't smoke. You exercise, you know—move, just move. Do what you love, whether that's flipping tires or dancing or walking; just do something you love, right? You eat healthy. You sleep. You take the logical preventative steps, right—you wear a seatbelt, you get vaccinated. You drink less alcohol, right? Less is best. And you surround yourself with people you love, and you have a good community. That's it, right? Oh, oh, the very most important thing you need to do: Pick the right parents, right? Make sure you have the right parents, because that speaks to the genetic-luck component to it—but more importantly, unfortunately, it speaks to socioeconomics, it speaks to equity, it speaks to the injustices that permeate our societies that really have an impact on how long you're going to live. Everything else you do, everything else you do at best is nibbling at the edges, and might be even hurting those other things.
Tayag: Do you have any advice for people who are trying to understand the research? Like, they really want to figure out: Is this real interesting new science, or is it just science-ploitation?
Caulfield: Never fall for what's often called the 'single-study syndrome.' Right? So if it's one study that sort of counters a body of evidence, that's interesting. But always remember: You have to generally be patient and wait for the science to evolve, wait for a body of evidence to emerge, and always remember that science is hard and it takes a very long time to go from an animal study to a clinical study to actually being in the clinic or being, you know, on your shelves at a grocery store. It takes an extremely long time if it ever is going to happen at all.
Tayag: How do you respond to people who say that data sources are biased or corrupted in some ways? This is something I encounter a lot in my work. Where, for example, on a story I recently worked on about raw milk, a raw-milk farmer told me that all of the data that I was looking at was produced by institutions that are funded by Big Ag. How do you counter that sort of thinking?
Caulfield: I think being transparent about that reality is important. And I think it's also important to highlight that on most of these topics, raw milk included, we can look at a body of evidence that points in the same direction, regardless of who the researchers are and how they're funded.
Tayag: I often hear people's frustration that there isn't more scientific attention paid to alternative therapies. And perhaps if there were, we'd have more information about the benefits of cold plunges, let's say, for example.
Caulfield: Something like cold plunges, you know, there is this—and first of all, there has been research on it. I think there's ongoing research on it. And I applaud individuals that are working in this space. But I also—and this is where the frustration comes in—should research really be driven by pop-culture interest in a topic, or even the need to debunk something because of the pop-culture interest in the topic? Or should it be driven by scientific plausibility? Unfortunately, too often, our scientific resources are devoted to topics that have become popular, and we're devoting resources to them because we have to debunk them. And of course, I mean, a really good example of that is something like the Wakefield study that suggested vaccines are tied to autism. Think of the tens of millions of dollars and the resources, right? And the researcher time that's been wasted proving definitively that there's no connection between autism and vaccines. And the only reason we had to do that is because, you know, in pop culture, that myth took on a life of its own. But we continue to study it, because we need more data to debunk it. Still—I recognize, and I'm glad, that people want evidence on things they're interested in. That instinct is healthy. The instinct for wanting more evidence on something, and good evidence. That's a good instinct. And that should be supported.
Tayag: We're going to take a short break. But when we come back….
Tayag: What's really going on here in this pursuit for longevity?
Caulfield: So if you look at even people like Bryan Johnson, I mean, how often is that guy photographed with the shirt off?
Tayag: Every time. I've never seen him with a shirt on.
Caulfield: Yeah. So that, I think that tells us something….
Tayag: More on the longevity movement and its charisma, after the break.
[Ad break.]
Tayag: So, Timothy, what's really going on here in this pursuit for longevity? You know, humans have been trying to defy death forever. And I'm curious, with the current longevity push, what are people really chasing? Are they really just trying to live longer?
Caulfield: I think this is a really fascinating question. Because I think the answer is both 'Yes, they want to live longer'—but if you listen to these influencers, and you flip through their books, they're promising more than just living longer, right? They are promising being better. They're promising sexy abs, a better love life, more success at work. It's an entire package, right? Living better, doing it better, being better. It's about this optimization, uh, concept. The other fascinating thing with the longevity movement—and this is interesting because I think it very much is about men, which historically was the case too, right? Living longer is very much about men. And there's this idea that if you're not doing this, there's something wrong with you. Like it's a noble pursuit. It's a righteous, righteous movement to be adopting all of these approaches. There was an interesting study—it was a qualitative study, so we have to be careful how we interpret the data—but basically, it was asking women their view on beauty products. And it was fascinating, because they kind of knew they probably didn't work, maybe they worked, but they still felt compelled to to use them. This idea that you ought to be doing this, right—and if you're not doing this, you're failing in some way—is a pressure that's always there.
Tayag: Mm hmm. And, is there a problem? Like, what are you concerned about with that pressure existing?
Caulfield: Well, first of all, I think that pressure is a marketing tool, right, to use these often unproven therapies. I think it can be exploitive, right, and can create anxiety. There are some studies—and, again, it's hard to study this well, so don't overinterpret this research—but it does suggest that this kind of pressure does shift how people think about things like public health. Because the emphasis is really you, like it's your job, right, to do these things. And if you are not healthier and not optimizing, hey, that's your problem. It's not my problem; it's not the government's problem; it's not, you know, your community's problem. That's your problem. If you emphasize sort of precision and personalization of health, it causes people to be less supportive of public-health interventions. But intuitively, that feels right, because it really is about you, you, you, you. The responsibility is on you. And if you're not doing it, you're failing.
Tayag: In pursuing all of these new biohacks—these techniques that are supposedly backed by new and cutting-edge science that isn't even out there yet—it makes me wonder if there's an element of mistrust involved in rejecting that public-health science that we already have long known about. Do you think mistrust plays a role?
Caulfield: I do. I do. I think it's really important to recognize that historically, there are groups that have been treated terribly by the health-care system, by the scientific community. Women and people of color not listened to, their problems not taken seriously by conventional medicine. The biomedical-research institution has not done enough research on women—same with people of color. So this is a genuine problem. Unfortunately, what's happening is the wellness industry, the longevity industry, they're exploiting that issue. They're not fixing it; they're exploiting it. They're creating more distrust in the conventional system and not rectifying the problems with the conventional system in order to sell products, to sell ideologies, to sell a brand. So it infuriates me, because these are real problems that need to be fixed. We didn't get it right. You know: Let's try to fix the problem, not sell products on the back of the problem.
[Music.]
Brennan: Yasmin, do you remember the other day we were working on an episode? And I happened out of the corner of my eye to see on your computer a headline about having a crayon's worth of microplastic in my brain.
Tayag: I do remember that. You were freaked out.
Brennan: I did not like that. And do you remember what I asked you?
Tayag: What did you say?
Brennan: I instinctively was like, What do I do? And you said some very practical responses—like 'Switch to glass containers; make sure your cutting board isn't plastic'—but it was not enough to fully quiet my mind. I spiraled for a full day.
Tayag: Oh!
Brennan: Because the things that are in my control, right—my Tupperware, for example—feel so disproportionate to all the factors that are out of my control. And so I really understand the impulse right now to want to take matters into your own hands when it comes to health and wellness. When you feel like there are all of these systems that don't have your health in mind.
Tayag: That is so real. Like, that is such a real way to feel right now: like you are not in control of so many things that affect your health. Our bodies are supposed to be our ground zero for autonomy and control. And there is something so empowering about being able to make healthy choices for yourself, especially if regulation is not keeping the plastic out of our brains. And it's even more frustrating to realize that there are companies that know that you and thousands of other people are feeling that way and have convinced you that you can buy your way out of that fear.
Brennan: And that's only looking at things through the individual perspective again, right? Because I want the crayons out of all the people I love's brains too, not just my own. And even all the brains I don't know. I don't want crayon anywhere.
Tayag: You know, I didn't think of it until Tim mentioned it, but it's really true that what feels so pertinent to this particular moment, is how individualized the pursuit of living longer feels. It's all about you and what you can do.
Brennan: Which is so ironic, because I have to guess that if we looked at the times in which the human lifespan has actually increased the most, I would guess it would be directly correlated with the invention of public-health initiatives.
Tayag: Oh, before we started to pasteurize milk—in, like, the late 1800s—a huge number of kids died from drinking bacteria-tainted milk.
Brennan: Right.
Tayag: And once pasteurization became standard, it turned that around. The kids stopped dying from milk. And then obviously vaccination, one of the biggest public-health initiatives, was estimated to have saved over 150 million lives in the last 50 years. And, you know, things we take for granted—like clean water or an actual sewage system, instead of flushing your waste into the East River—hugely decrease deaths from illnesses.
Brennan: But these inventions often take time, right? These new initiatives can move slowly. So what do we do now while we wait?
[Music.]
Tayag: So I want to zoom out a little bit and come back to this question of: How are people supposed to try to live longer if that is something they want to do? In your new book, Certainty of Illusion, you discuss the illusion of thinking you have the answers to everything because we have so much information at our fingertips. The illusion is the certainty. But how can people break free of the illusion that they can hack their way into living longer?
Caulfield: Alas, life is pretty random, you know. And we want to control it. That's one of the reasons conspiracy theories emerge, right? You know: People desire patterns, they desire answers, they want answers that sort of fit with their worldview. So, you know, recognize that there often is a lot of uncertainty and randomness, and get comfortable with that. And there's a lot of uncertainty in science. Science is about uncertainty, right? Evidence can evolve. If science said one thing 20 years ago—and science isn't a person, it's not an institution, it's not an industry. Science is a process, right? And if we used that scientific process to come to a conclusion 20 years ago—and that evolved, and that has evolved—science isn't wrong. That's science working, right? You know, aspirin; our view on who should be taking aspirin as a preventative measure. That's evolved, right? You know, our view on using BMI as a tool for public health. That's evolved. That's a good thing. That's science evolving. Don't view it as a reason to get frustrated about public health or the institution of science. Celebrate that evolution of science and of evidence. Because if you're not using that systematic tool to accumulate knowledge, if you're not using science to try to understand our world and make decisions, what are you going to use? We might have a huge breakthrough, and if that does happen it's going to be really big news. I often ask—I did this in my last class, just last week—I asked the class: name 10 genuinely big scientific health breakthroughs that have happened in the last century. Right? Genuinely transformative health breakthroughs—it's hard, right?—that have actually revolutionized. So you've got, like, clean water. That's more than a hundred years. You have, you know, antibiotics. The list is pretty short, right? It's pretty short. You know, the new GLP-1s—like Ozempic and its competitors—I think that's fascinating, right? Recognizing that we're still accumulating evidence about side effects and long-term benefits and harms, but it's a pretty short list. And so: Remember that, right? Remember that, and lean back, and lean into those basic things we can do for ourselves, and—really, really importantly—for our community, building communities that foster those basic things.
[Music.]
Caulfield: Aging shouldn't become a contest, you know, that you suffer through to get to the finish line. It's not a contest. And holy cow, it sounds kind of New Age-y for a guy, such a science geek. But I think it really is about living well, and enjoying life, and enjoying your friends and family, and enjoying the journey. How New Age-y is that? And the irony, of course, is the research tells us that living well and living a happy life—that helps with longevity too, right? That helps your ultimate goal too. So, yeah: pulling back from this idea of optimizing every corner of your life to, hey, living well.
Tayag: Thanks so much, Tim. This has been such a pleasure.
Caulfield: Thank you.
[Music.]
Brennan: Yasmin, I'm still thinking about that question that I asked you about the microplastics. 'What do I do?' And I think what I really wanted to hear in that moment was, 'It's fine. It's okay.' You're like … 'It's not.'
Tayag: Sorry.
Brennan: No, and I would know that it's not truthful, right? I know that it's not okay. It's not fine. And in cognitive behavioral therapy, this is something called reassurance seeking. Have you heard of this?
Tayag: I haven't.
Brennan: There's this book written by these two psychologists, Martin Seif and Sally Winston, called Needing to Know for Sure, that a friend who has a very similar internal monologue to me recommended. And it's a CBT guide for compulsive checking and reassurance seeking. And instead of trying to constantly seek affirmation that everything is okay, the book helps you try and sit in the uncertainty and get comfortable with the idea that often, we just can't know what's going to happen. Which is really hard.
Tayag: It's so hard, I think, from like a health perspective. People are bad at thinking about risk. And that's really what all of these public-health interventions, all of the health interventions that are available to us, are all about: reducing our risk. It will make you less likely to get cancer or to have a bone fracture later in life. But it's never guaranteed, and that's the whole thing about risk—there's no 100 percent sure way to get rid of everything. But you're bringing that risk down a little bit, and that's the best we can do.
Brennan: And what I like about your conversation with Tim is that, you know, it kind of sits in a middle ground, right? We can't 100 percent know that a certain supplement is going to increase our lifespan. And we can't know that a new superfood is going to definitely help us age up. But there are these tangible steps that we can work into our day to day at any point to commit to a practice of living healthier.
Tayag: Yeah; we don't have all the answers, but we have some of the answers.
Brennan: And I think I can sit in that. You know, that might be enough for me. And for the days that I can't, when I can't sit in that thought, you know—those are the days that I delight in jumping into water.

‘Harmful' TikTok trend fueling new wave of ‘dangerous' diet culture

TikTok has long been a breeding ground for viral trends, but its latest subculture, 'SkinnyTok,' is reigniting old diet culture in a digital age. Behind the trendy filters and catchy sounds lies an extremely problematic reality – a community where thinness is idolised, extreme calorie deficits are glamorised, and the pursuit of a shrinking body is celebrated, often at the expense of mental and physical health. The rise of SkinnyTok Advertisement SkinnyTok refers to a corner of the internet where creators openly document their weight loss journeys, post 'what I eat in a day' videos featuring alarmingly low calorie counts, and share 'body checks' (videos where people weigh and measure themselves). Some even boast about 'gaslighting' themselves into being skinny, or confess to daily gym visits out of a fear of being 'fat' – even when they already fit society's narrow beauty standards. TikTok has, for its part, attempted to clamp down on this content. 5 TikTok has long been a breeding ground for viral trends, but its latest subculture, 'SkinnyTok,' is reigniting old diet culture in a digital age. Volodymyr – Advertisement Searching for 'SkinnyTok' now triggers a warning: 'You're not alone' and prompts people to seek help if they're struggling with body image, food, or exercise. Influencers like Liv Schmidt, who built a following of over 670,000 with her 'blonde and skinny' persona, have been banned. Yet, the algorithm still seems to serve up the very content it claims to protect users from. So, what can people do to safeguard themselves online? Advertisement First, you need to understand what SkinnyTok is, how the trend has managed to gain such a huge following, and who is most at risk. 5 Searching for 'SkinnyTok' now triggers a warning: 'You're not alone' and prompts people to seek help if they're struggling with body image, food, or exercise. Odua Images – The personal toll Jemma Haythorne, a confidence coach, speaker, and podcaster, knows firsthand the damage that online diet culture can do. 'I started hating my body when I was 12 years old, but really spiralled into disordered eating when I was 16. My friends and I would follow skinny content on Tumblr, using it as 'motivation' to eat less to achieve our goals of being thin,' she tells Advertisement For Haythorne, the pressure peaked during Schoolies, when the prospect of hundreds of Facebook photos led her to subsist on scarily low calories and avoid water to prevent 'bloating' – all ideas she picked up from social media. 'Instagram then became a dangerous place too for someone with body image issues and a fraught relationship with food,' she says, adding that the rise of fitness influencers and 'clean eating' trends was fuel for her already disordered behaviors. Her lowest point came between 2017 and 2019. 'Social media told me that everyone was thin, gorgeous, tanned, hairless, toned, and successful, because that's what the algorithm was serving me, and those were the people who were platformed,' she says. 'The message that I received was that I was failing, because no matter how hard I tried, I couldn't meet those standards.' Haythorne believes that without social media, she would never have developed an eating disorder, depression, and anxiety to the extent she did. The cyclical nature of online trends She says she has witnessed body ideals shift over the years, from ultra-thin, to athletic and toned, to the 'Kim Kardashian' hourglass, and now back to just 'plain thin.' Advertisement Despite the rise of the body positivity movement, she's sceptical about its real-world impact: 'The body ideal has always come back to being in a smaller body — something that I desperately hope we can change in the future.' The influencer effect Influencers and content creators play a massive role in shaping body image perceptions, Haythorne argues. 5 Psychologist Carly Dober confirms that SkinnyTok can trigger and exacerbate disordered eating behaviors and eating disorders. Kate – 'Those who post content that encourages unhealthy relationships with food and bodies are directly damaging their audience. SkinnyTok content is incredibly problematic and harmful, and when this becomes trendy, it becomes dangerous, especially for those who don't have the knowledge and understanding of how damaging it is.' Advertisement But the damage isn't always obvious. Seemingly innocuous 'before and after' photos reinforce the idea that smaller is better, while meal inspiration videos suggest that copying someone's diet will yield the same body. 'Any form of editing of bodies or faces makes people think they need to live up to looking like that in order to be beautiful or worthy, yet the person themselves doesn't even look like that,' she notes. She claims that while platforms like TikTok and Instagram have a responsibility to manage the harm they promote, individual influencers must also be aware of their impact. The psychological impact Advertisement Psychologist Carly Dober confirms that SkinnyTok can trigger and exacerbate disordered eating behaviors and eating disorders. 'These trends influence how people perceive and evaluate their own bodies, and the bodies of others. Behaviorally, people may self-isolate, which can also impact their work, education, and relationships,' she explains. Beyond the psychological impact, the physical consequences are dire too. Eating disorders can harm the heart, digestive system, bones, teeth, and mouth. Advertisement Typical serious side effects include low blood pressure, slow or irregular heartbeats, feeling tired, weak, dizzy, or faint, constipation and bloating, irregular periods, and weak bones. Who's most at risk? According to Dober, certain groups are especially vulnerable to the dangers of SkinnyTok. These include: – Adolescents (especially those aged 12–25) with a median age of 18 – Women during key transition periods (e.g. finishing school) 5 'SkinnyTok content is incredibly problematic and harmful, and when this becomes trendy, it becomes dangerous, especially for those who don't have the knowledge and understanding of how damaging it is,' experts said. LIGHTFIELD STUDIOS – – Women with Polycystic Ovary Syndrome or diabetes – Athletes and those in appearance-focused activities like dancing – People with a family history of eating disorders – Anyone seeking help for weight loss or who has engaged in dieting or disordered eating The role of TikTok's culture Qualified nutritionist Yaz Jackson sees SkinnyTok as part of a broader trend of 'normalizing' harmful behaviors on TikTok. She notes that TikTok's culture is different from Instagram's: 'You can 'get away' with more. It's more of a diary, people feel like they can say whatever, and it's lighthearted, and nobody judges. I've seen creators say things like 'I could never share this on Insta, they'd judge me, but I can tell you guys,'' Jackson believes there's a trend of radical honesty emerging on TikTok, where creators are praised for sharing 'the tea' – the secrets behind their appearance, whether it's the use of medication, diets, or cosmetic surgery. Their content is being favoured, as people applaud them for being 'real' and 'not fake' – i.e., unlike the countless models and celebrities who pretend they eat pizza and burgers when the reality is much different. 'This trend then gains traction because when enough people make something okay to talk about again, they feel safer,' she said. 'Things that were once stigmatized are now being accepted – but only if you are super honest and transparent about it. People love that.' The dangers of unqualified advice Dr. Zac, a GP, urges people to exercise caution when seeking health advice online, especially when it comes from unqualified creators. 'Health advice should come from qualified professionals – doctors, registered dietitians, clinical psychologists – people with actual credentials, not just abs and a ring light. If someone's offering drastic weight loss 'hacks' or pushing extreme transformations, especially if they're profiting from it, be wary,' he says. Things to look out for include: 'Are they citing evidence-based sources? Do they promote balance over extremes? Are they championing sustainable health, or quick fixes and aesthetic perfection?' How to safeguard your mental health Dober and Zac recommend several strategies for protecting yourself online: Curate your feed: Block or mute content and creators that promote unhealthy behaviors 5 SkinnyTok refers to a corner of the internet where creators openly document their weight loss journeys, post 'what I eat in a day' videos featuring alarmingly low calorie counts, and share 'body checks.' Floral Deco – Use platform tools: Filter out triggering keywords where possible Limit screen time: Reduce endless scrolling to avoid algorithm rabbit holes Follow positive accounts: Such as ones that promote body neutrality, mental health, and self-compassion Seek support: If you're struggling, reach out to a psychologist or trusted professional. And as Zac puts it: 'Healing starts when we stop punishing ourselves and start listening to what our body and mind actually need.'

Why Non-Surgical Nose Jobs Are Replacing the Knife

Surgical rhinoplasty may be the gold standard, but in 2025, the scalpel is no longer the default. Today's patients want precision without permanence, and they're getting it in under 30 minutes. 'More and more patients are looking for impactful changes without the permanence or downtime of surgery,' says Dr. Ali Ghiyam, MD, of Simi Doctors. 'What used to be a multi-week commitment is now a 20-minute visit with results that can be just as transformative.' Enter the liquid nose job, a fast, reversible fix that's transforming the world of facial aesthetics, one hyaluronic drop at a time. A new generation of patients is reshaping beauty culture, and it's happening through subtle 'tweakments' instead of full-scale transformations. With platforms like TikTok flooding feeds with sculpted side profiles and filter-perfect noses, people are showing up to appointments with screen grabs, not celebrity references. What they want isn't dramatic: it's a touch-up. A straighter bridge. A more lifted tip. A camera-friendly angle. Thanks to the tweakment trend, those wishes now come true with a syringe instead of a scalpel. 'A liquid rhinoplasty uses hyaluronic acid filler to smooth bumps, lift the nasal tip, or create a straighter profile,' explains the Cleveland Clinic. 'It's fast, non-invasive, and delivers immediate results, often with zero downtime. The key advantage? It's temporary and reversible.' The procedure takes less than 30 minutes. Filler (often Juvederm or Restylane) is injected to contour the nose and refine its shape without reducing size or correcting internal structure. It's ideal for patients seeking cosmetic improvements without long recovery or surgical commitment. And if you don't love the results? Hyaluronidase can dissolve the filler in minutes. Liquid rhinoplasty has expanded far beyond the surgery-averse. It's now the go-to tweak for influencers, professionals, and even patients test-driving their future surgical look. Non-surgical procedures like this are part of a broader movement: over 4.4 million filler treatments were performed in the U.S. in a single year, with nose reshaping topping the request list. For younger patients, especially, the appeal lies in control: you can try, adjust, or undo, no operating room required. Despite the no-scalpel promise, liquid rhinoplasty is still a medical procedure, and one that carries risk. The nose contains critical blood vessels. If filler is improperly placed, it can lead to vascular occlusion, potentially causing tissue damage or even blindness. That's why expert care is non-negotiable. Choose a board-certified provider with advanced knowledge of nasal anatomy and vascular safety. Minor swelling and bruising are common. But if you experience pain, skin blanching, or vision changes, you should seek immediate medical attention. The rise of liquid nose jobs marks a shift in how we approach beauty: not as a permanent destination, but as a journey we can refine in real-time. A 2022 NIH study found that younger patients are significantly more likely to choose non-invasive procedures for cosmetic concerns, citing flexibility, reduced downtime, and lower risk. This isn't about perfection, it's about personalization. It's skincare meets sculpting, minus the irreversible choices. If you're curious about rhinoplasty but not quite ready for the OR, this might be the aesthetic middle ground you didn't know you needed. Expect to pay between $600 and $1,500, with results lasting 6 to 12 months depending on the product used and your body's metabolism. Just remember: this is still a medical procedure, not a facial. Choose wisely. Ask questions. And don't let a filter talk you into a filler without doing your homework. A liquid nose job, also known as non-surgical rhinoplasty, is a cosmetic procedure that uses injectable dermal fillers (usually hyaluronic acid) to temporarily reshape the nose. It can smooth bumps, enhance symmetry, and lift the nasal tip without the need for surgery or downtime. Most non-surgical nose jobs last between 6 and 12 months, depending on the type of filler used and how your body metabolizes it. Some patients may need a touch-up around the 9-month mark to maintain results. Yes, when performed by a qualified, board-certified injector. However, the nose is a high-risk area due to its blood vessel structure. Complications like vascular occlusion are rare but serious, so safety depends on the skill and anatomical expertise of the provider. Technically, no, it won't reduce the size of your nose. But by adding filler in strategic places, a liquid rhinoplasty can create the illusion of a smaller, straighter, or more balanced nose by improving proportions and smoothing out irregularities. The average cost of a liquid nose job in the U.S. ranges from $600 to $1,500, depending on the injector's experience, location, and filler brand. It's significantly more affordable upfront than traditional rhinoplasty, but the results are temporary. Yes. If hyaluronic acid filler is used, the procedure is said to be reversible. An enzyme called hyaluronidase can be injected to safely dissolve the filler within 24 to 48 hours. This procedure is ideal for individuals who want minor cosmetic refinements (such as smoothing a dorsal hump or lifting the nasal tip) but aren't ready for the permanence, downtime, or cost of surgery. It's not recommended for those needing structural correction or breathing improvements. Click here to learn more about Dr. Ali Ghiyam, MD.

‘McMigraine': Does TikTok's Coke and Fries Hack Actually Work for Migraine?

TikTok users are touting a migraine hack involving McDonald's fries and a Coke to relieve their symptoms. Experts say the combination of salt, sugar, and caffeine may provide temporary relief from migraine. However, processed foods high in sodium, fat, and sugar may worsen migraine symptoms and contribute to long-term health problems. Several strategies may support migraine relief, such as magnesium and omega-3s. It's estimated that 39 million people in the United States experience migraine. If you're one of them, you may have heard of the 'McMigraine meal,' a proposed migraine relief hack trending on social media platforms like TikTok that involves consuming McDonald's fries and a Coke. A migraine is more than just a bad headache. It's a complex neurological condition often accompanied by intense, throbbing pain, sensitivity to light and sound, and nausea, which can be debilitating. While there are medications available to prevent and treat migraine, they don't work for everyone. When a migraine attack hits, most people will do anything to feel better, even if it means consuming ultraprocessed foods like fries and a soda laden with sugar. Here's how the McMigraine trend works, and what experts think about its supposed benefits. A McMigraine meal: Not a reliable cure Kezia Joy, registered dietitian and medical advisor at Welzo, said it's important to distinguish between anecdotal evidence and clinical recommendations for any ailment, including migraine. 'Although the concept may be based on real-life experiences, it's not grounded in clinical research. It may provide temporary solace for some, but it's not something that should be in anyone's regular or safe migraine treatment repertoire,' she told Healthline. Likewise, specialist registered dietitian Nichola Ludlam-Raine agreed, cautioning that fries and a Coke are not a reliable treatment. 'While I completely understand that people living with migraine may be desperate to try anything that offers relief, this isn't a strategy I'd recommend trying frequently from a nutritional or clinical perspective,' she told Healthline. McMigraine benefits are short-lived Many people have claimed a McMigraine meal helped relieve their migraine symptoms. Is there any plausible scientific reason why salty fries and a sugary drink might offer temporary relief for some people with migraine? Joy noted a few physiological reasons why someone might experience temporary relief after eating salty, high carb foods and drinking caffeine. 'Caffeine, which is present in Coke, constricts blood vessels, and in some forms of migraines, it can relieve pain,' Joy explained. 'At the same time, high-salt or high-carbohydrate foods may aid in correcting a mild electrolyte or blood sugar imbalance,' she continued. 'If a person has missed a meal or is just a little dehydrated, the fries and soda may provide temporary relief.' Ludlam-Raine shared a similar synopsis of the potential benefits of a McMigraine meal. 'Migraines can be triggered or worsened by low blood sugar, dehydration, or electrolyte imbalances, and so salty fries may help the body retain fluid, while the caffeine and sugar in a Coke could raise blood sugar and offer a quick boost in alertness or energy,' she pointed out. Ultimately, though, Ludlam-Raine said the benefits are likely to be short-lived and won't address the root cause of the problem. In fact, for some people with migraine, the combination of salt, sugar, and caffeine could worsen their symptoms. 'High-fat and salt foods can be problematic for others, especially if their migraines are linked to dietary triggers or underlying conditions like high blood pressure,' Ludlam-Raine noted. Does a McMigraine meal have any risks? The potential to worsen migraine symptoms aside, there are other risks to consider when using unhealthy foods as a migraine cure. 'Fast food may be convenient, but it can also be high in sodium, saturated fats, and added sugars,' Joy said. 'If consuming it becomes habitual, it can create inflammation in the body, which in turn, can make headaches worse over time.' There are other long-term health risks to consider, too. 'Relying on fast food regularly may contribute to long-term health issues like weight gain, insulin resistance, high blood pressure, and poor gut health, all of which can potentially worsen migraine frequency or severity,' Ludlam-Raine said. Additionally, it may discourage people from addressing triggers and other factors that contribute to migraine attacks.' 'Excessive reliance on fast food as a fix can also skirt any underlying health issues that need to be diagnosed and treated,' Joy pointed out. 'Relying on it instead of seeking out treatments that work and are sustainable isn't good. It's also important to see food in the context of your entire lifestyle, not as a quick fix.' Evidence-based migraine interventions There are many strategies for managing a migraine that don't involve ordering from a McDonald's drive-thru. Joy said there are some specific nutrients you should look out for, such as magnesium. 'It's present in leafy greens and nuts, is involved in nerve functions, and can reduce the frequency of migraine in some people,' she explained. Other nutrients may offer some relief from migraine as well. 'Riboflavin-rich foods (vitamin B2) and co-enzyme Q10 have also been investigated for their potential benefits,' Joy said. 'Omega-3 fatty acids, found in fatty fish, may also reduce inflammation and support brain health.' According to Ludlam-Raine, other ways to prevent and manage migraine include: staying hydrated throughout the day eating regular, balanced meals that include slow-release carbohydrates, protein, and healthy fats to maintain steady blood sugar levels avoiding specific triggers like aged cheese, alcohol, or artificial sweeteners keeping a food and symptom diary to identify personal patterns While certain wellness strategies can help prevent migraine, they may not be able to stop one in progress, which could explain why some people have turned to a McMigraine meal for relief. Clinical treatment for a migraine generally involves both acute and preventive options. 'Drugs, including triptans, CGRP inhibitors, and some anti-seizure and blood pressure drugs, can help some people,' Joy said. 'Non-pharmacologic treatments, like biofeedback, cognitive behavioral therapy, and neuromodulation devices, can also be effective.' Migraine symptoms can be debilitating, and when they strike, it may be tempting to seek the quickest and most convenient intervention. For some, that might be McDonald's fries and a Coke.
