• Are Artificial Sweeteners Actually Bad For You? 27.05.2026 1j 25mnt

  In 1879, a chemist named Constantin Fahlberg sat down to dinner without washing his hands after a day spent handling coal tar. His bread tasted strangely sweet. So he went back to the lab and started tasting everything on his bench until he found the source. That was saccharin, the first artificial sweetener, discovered because a man would not wash his hands before dinner. Nearly 150 years later, we are still arguing about whether the stuff is going to kill us.This week, Zoë and Kylee dig into the question every diet-soda lover has had to defend at a gas station: are artificial sweeteners actually bad for you? They trace how a coal-tar accident became a billion-dollar industry, why the WHO's "possibly carcinogenic" label on aspartame puts it in the same risk tier as pickled vegetables and working as a carpenter, and how Donald Rumsfeld personally muscled aspartame through the FDA. The saccharin cancer scare that haunted a generation came from male rats dosed with the equivalent of hundreds of sodas a day, through a mechanism human bodies do not even have.Along the way: the wartime rationing that built the sweetener industry, the cyclamate the US banned and never reinstated while the rest of the world kept drinking it, the every-fifteen-years villain cycle that has run through fat, high-fructose corn syrup, gluten, and seed oils, the genuinely fascinating Suez microbiome research where scientists grew human gut bacteria in mice, the stevia-in-a-petri-dish problem, and the erythritol heart-attack headline that fell apart the moment anyone read the study.Plus: why these things were always sold to women as a permission structure, the one category athletes actually need to watch (sugar alcohols, and the osmotic chaos they bring to a long run), the client drinking ten Liquid IVs a day, and a hot-takes round that settles Diet Coke versus Coke Zero once and for all.Listen for the full story.This episode is brought to you by:rabbit: Built by runners, for runners.

• Should You Count Calories? The Wild History and Questionable Science Behind Calorie Counting 13.05.2026 1j 29mnt

  Should you count calories? A century ago, a Los Angeles doctor named Lulu Hunt Peters sold two million copies of a book that taught American women to count calories as a patriotic duty during WWI. She invented the 100-calorie snack pack. She set the 1,200-calorie floor that still haunts diet apps in 2026. The framework she popularized is still running your relationship with food.This week, Zoë and Kylee dig into the question every active person has wondered about: should you be counting calories? They trace how a unit of heat invented to measure factory worker rations became the dominant logic of American eating. Where the 2,000-calorie label on every food package actually came from (it isn't science, it's a 1990 design choice). Why calorie counting is legally allowed to be 20 percent wrong before it ever reaches your plate. And why a framework with this many cracks has held on for a hundred years.Along the way: what calorie counting did to the American food supply during the low-fat era, what the Biggest Loser metabolic adaptation research actually showed, why even registered dietitians can't accurately track their own intake, what set point theory says about why restriction backfires, and whether calorie tracking apps are tools, traps, or both. For athletes, the questions that actually matter for performance, and what the research says about who calorie counting helps and who it harms.Plus: the early feminist origins of dieting (yes, really), why your microbiome is doing math your app can't see, and why this number keeps its grip on us even when the science says it shouldn't.Listen for the full story.This episode is brought to you by:rabbit — Built by runners, for runners.

• Food Allergies, Intolerances, and Sensitivity Tests 29.04.2026 1j 21mnt

  This week, Zoë mailed a chunk of her hair to a stranger in Florida. For science. For journalism. For your benefit, really. The $60 hair sample test came back flagging her as "highly reactive" to 210 foods, including emu, ostrich egg, hot dog, and ground horse meat. Reader, she has not eaten ground horse meat in over a decade.The food sensitivity industry is a multi-billion-dollar grift built on real symptoms and fake frameworks. We trace it from 1906, when allergy was first defined as a real clinical thing, through the 1950s clinical ecology movement, through cytotoxic testing, IgG panels, electrodermal screening, and bio-resonance, and finally to the at-home hair test in your DMs. It's the same idea in different packaging every decade. Like a body-snatcher, but for grift. (We use a lot of John Carpenter references in this one.)Then Kylee walks through what the science actually says: the difference between IgE allergies, IgG sensitivities, and intolerances. What real diagnostic testing looks like (skin prick tests, blood panels, hydrogen breath tests, structured elimination diets with a professional). Why hair testing, IgG panels, and bio-resonance devices have no validated diagnostic mechanism. And why these tests disproportionately target women, who are statistically more likely to feel dismissed by their doctors and more likely to seek answers in the wellness market.We also get into why endurance athletes are uniquely vulnerable to this stuff. When your gut acts up during training, the wellness industry hands you a list of 210 foods to eliminate. Your sports dietitian hands you a fueling plan. Guess which one tends to lead to a stress fracture.The bottom line: your symptoms deserve a real answer. Don't let a hair test substitute for actual care.This episode is supported by:rabbit — Use code YOURDIETSUCKS10 for 10% off at runinrabbit.com Their trail line is genuinely the only running gear we actively look forward to wearing.Tailwind Nutrition — Use code YOURDIET20 for 20% off at tailwindnutrition.com.

• Is Natural Food Actually Healthier? 15.04.2026 1j 23mnt

  In 1997, a 14-year-old named Nathan Zahner convinced 43 out of 50 classmates to sign a petition banning a dangerous chemical called dihydrogen monoxide. The chemical was water. This episode is everything that happened next, scaled up to a $50 billion industry and, eventually, federal food policy.Zoë and Kylee trace the naturalistic fallacy: the assumption that natural equals good and artificial equals bad. It's the implicit logic behind clean eating, anti-GMO panic, supplement marketing, anti-vaccine rhetoric, and a significant chunk of sports nutrition culture. This episode follows that logic from Sylvester Graham's Victorian theories about white flour and masturbation, through John Harvey Kellogg's Battle Creek Sanitarium, through the Make America Healthy Again commission's 2025 decision to replace heavily regulated synthetic dyes with natural alternatives that are, it turns out, subject to less FDA oversight than the dyes they replaced. Botulinum toxin is completely natural. Synthetic folic acid has prevented hundreds of thousands of neural tube defects. Nature is not a wellness coach.

And if you want bonus episodes, early access, and our eternal gratitude, support us on Patreon at patreon.com/YourDietSucks.Caffeine is the most widely consumed psychoactive substance on earth — and somehow it's still got two extremely loud camps screaming past each other. On one side: the wellness-bro "caffeine destroys your adrenals, drink my mushroom latte" crowd. On the other: the guy on TikTok who takes 800 milligrams a day and wants you to up your dose. Both of them are wrong. Both of them are extremely entertaining.In this episode, Zoë and Kylee dig into how caffeine actually works, the adenosine receptor science, the performance research, the optimal dosing for endurance athletes, and what it's actually doing to your sleep, hormones, and anxiety levels (spoiler: more than you think, less than the fear-mongers claim). They trace the history of human caffeine consumption from ancient China to Sufi monks using coffee as a pre-workout for night prayer, through the Enlightenment coffee houses that accidentally invented capitalism, all the way to a 300-milligram neon energy drink with a skull on it. There's also a full breakdown of the pre-workout industry's stimulant escalation problem, why adrenal fatigue isn't a real diagnosis, how your menstrual cycle affects caffeine metabolism, and whether the caffeine taper before a race is actually worth the two weeks of misery. Plus: the 1904 Olympic Marathon featured rat poison, brandy, and a man who hitched a ride in a car for 11 miles. Dry scooping sent multiple people to the hospital. And "energy is a choice" is not a peer-reviewed finding.We cover it all.This episode is supported by rabbit — use code YOURDIETSUCKS10 at runinrabbit.com/collections/womens-new for a discount on their trail line.

This episode follows that instinct back to one of its oldest sources, the American evangelical church. Zoë and Kylee are joined by Leslie Schilling, RDN, CSSD, sports dietitian, eating disorder specialist, and author of Feed Yourself, to trace how food, bodies, and spiritual worthiness got so tangled together, and what it costs the people caught inside that tangle. From Pope Gregory's taxonomy of gluttony in the sixth century to Rick Warren's Daniel Plan weigh-ins, "your body is a temple" taken wildly out of context, and why eating disorders tied to religious identity are among the hardest to treat.

Kylee breaks down how real elimination diets work, why this one poses specific risks for athletes, and what the plant-based Whole30 contradiction reveals about whether the rules were ever based on science at all.Support Your Diet Sucks on Patreon for bonus episodes, weekly threads, recipes, and AMA access: patreon.com/yourdietsucks.This episode is brought to you by rabbit — use code YDSMARCH10 for 10% off at rabbit.com.

• Does Intermittent Fasting Actually Do Anything? 18.02.2026 1j 21mnt

  Intermittent fasting is the most Googled diet-related term on the planet, except everyone who does it will tell you it's not a diet. It's a protocol. An eating window. A lifestyle. An optimization hack. Definitely, absolutely, under no circumstances a diet. You just don't eat for sixteen hours. Totally different.In this episode, we trace IF from ancient religious fasting traditions through its secularization and commodification, afrom Martin Berkhan's Leangains forum and its tagline ("fuck breakfast") to Michael Mosley's BBC documentary, Hugh Jackman's Wolverine physique, and Jack Dorsey describing his weekend-long fasts as "hallucinating" like that's a selling point. We walk through how a Nobel Prize in yeast biology became a justification for skipping breakfast, why Jason Fung's The Obesity Code scored 31% on scientific accuracy and still became the IF bible, and how the fasting app market turned one simple rule into a multimillion-dollar industry.Then we get into what the science actually says. We break down the claimed mechanisms — metabolic switching, autophagy, insulin sensitivity — and look honestly at where the evidence lands. Spoiler: the mechanisms are real, but the confidence far outpaces the human data. The first direct measurement of autophagy in humans was published in 2025. Mouse metabolism runs seven times faster than ours. And the landmark Liu et al. trial in the New England Journal of Medicine found that time-restricted eating is no better than regular caloric restriction for weight loss. You're not metabolic switching. You're just eating less.We also dig into what IF means for active people (no performance benefit across any exercise type, real risk of under-fueling and RED-S, and a protein distribution problem that no eight-hour window can solve), what the AHA, ADA, NIA, and ISSN actually say about it, and the robust research linking IF to eating disorder behaviors across all genders — including a landmark study showing that fasting was a stronger predictor of binge eating disorder than any other form of dietary restraint. Fasting is listed in the DSM-5 as a compensatory behavior. Just because you give it a different vocabulary doesn't mean your body experiences it differently.Your body is smarter than any fasting app. Also, breakfast slaps..This Episode's Sponsors:rabbit — Code YDSFEB for 10% offOsmia — Code YDS20 for 20% offTailwind — Code YOURDIET20 for 20% offMicrocosm Coaching — Book a free consultationFull references, episode archive, and our advertising ethics policy at yourdietsuckspodcast.comHosted by: Zoë Rom & Kylee Van Horn, RDN
• Do Anti-Inflammatory Diets Actually Work? 04.02.2026 1j 17mnt

  Connect With Us: ⁠Patreon⁠ | ⁠@yourdietsuckspod on instagramThe wellness industry wants you to believe your body is on fire. Tired? Inflamed. Bloated? Inflamed. Sad? Believe it or not, inflamed. But what does inflammation actually mean, and should athletes be worried about it?In this episode, we trace how inflammation went from a specific biological process to a wellness Rorschach test that can sell you anything from turmeric lattes to $200 supplement stacks. Zoë covers the history, from 1970s eicosanoid research to the glucose goddess's empire of banana fear, while Kylee breaks down what the research actually shows about anti-inflammatory diets.We cover the Mediterranean diet, elimination protocols like AIP, why sugar isn't the devil, why most inflammation claims come from rodent studies using absurd doses, and why under-fueling might be more inflammatory than anything in your pantry.

• The Vegetarian Diet 21.01.2026 1j 20mnt

  ⁠Check out our website for a full list of episodes and references!⁠Support us on Patreon, or Apple Subscriptions or Spotify Premium!Can you build muscle, train hard, and actually perform on a vegetarian diet? Do plant-based eaters need more protein? Is iron deficiency a real concern or just wellness industry noise? This week, Zoë and Kylee dig into what the research actually says about vegetarian diets for athletes and active people, no Game Changers propaganda, no carnivore fear-mongering, just science.Turns out vegetarian athletes do need about 20-30% more protein than omnivores to achieve the same muscle protein synthesis. Kylee explains why leucine matters, what PDCAAS scores actually mean, and which plant proteins are worth prioritizing (and which ones are working against you). Then Zoë gets quizzed on iron, B12, zinc, omega-3s, and protein combining in a game called Truth or Deficit, and her performance is, frankly, embarrassing for someone who's been vegetarian since age 17.They also talk about something that doesn't get discussed enough: the research linking vegetarianism and disordered eating. Studies show plant-based eaters are about twice as likely to report orthorexic symptoms as omnivores, and Zoë gets honest about her own history using veganism as eating disorder cover. Plus: 2,500 years of people being unhinged about dietary purity, including Pythagoras possibly getting murdered because he refused to walk through a bean field, the anti-masturbation origins of graham crackers, and how "you are what you eat" thinking has been claimed by feminist abolitionists and literal Nazis alike. The plants aren't the problem. The purity logic might be.Vegetarian diets can absolutely support your training and your health. They just require more planning, more attention to a few key nutrients, and an honest conversation with yourself about why you're doing it.Sponsors:Osmia Skincare — Code YDS20 at osmiaskincare.com for 20% offTailwind Nutrition — Code YOURDIET20 at tailwindnutrition.com for 20% offMicrocosm Coaching — Free consult at microcosm-coaching.com

  This episode is presented in partnership with Mount to Coast.Use code YDS10 for 10% off at mounttocoast.comWhat does it take to run 603 miles in six days?We recorded this episode live at The Running Event with Megan Eckert, who set the women's six-day world record this past May at the Gomu World Championships in France, becoming the first woman in history to break 600 miles. She also holds the women's backyard ultra world record (362 miles at Big Dog's) and somehow still works full-time as a middle school special education teacher and high school track coach.Megan didn't come up through the traditional running pipeline. She started as an adult, dealt with undiagnosed iron deficiency for years, and figured out her approach to fueling through trial, error, and eventually working with a sports nutritionist. At 38, she's proof that it's never too late, and that eating enough is actually faster than eating less.We talked about iron deficiency in female athletes and why "normal" lab ranges don't work for us, how to fuel multi-day events with real food (Doritos included), carbohydrate periodization without overthinking it, body image pressure on women as we age in sport, and why her supplement routine is probably simpler than yours.Follow Megan: @meg_eckert on InstagramFollow YDS: @yourdietsucks on Instagram | yourdietsucks.comThis episode is brought to you by Mount to Coast, the first performance footwear brand designed specifically for ultrarunning.

• Men, Masculinity, Body Image and Disordered Eating 07.01.2026 1j 17mnt

  We brought the husbands on for this one. Sean Van Horn and TJ David join us to talk about eating disorders in men, disordered eating in male athletes, and how the wellness industry preys on masculine insecurity with different packaging but the same playbook.First up: a game called Influencer or Dictator, where the guys guess whether quotes about discipline and suffering came from David Goggins or Joseph Stalin. It was harder than it should have been.Ten million American men will experience an eating disorder. Men make up 25 percent of cases, but only 10 percent of treatment, and the shame is double because you're told you have a "women's disease." Meanwhile, gym culture sells restriction as optimization and calls it biohacking. If you put it in a spreadsheet, it's not mental illness, right? It's astrology for boys.We trace the history from Charles Atlas selling masculinity during the Great Depression to G.I. Joe's impossible biceps to today's Ginfluencer explosion. Every masculinity crisis spawns a fitness boom. Sean shares his own eating disorder recovery, and we break down the red flags hiding in plain sight: cutting, clean eating, cheat days, earning food, no rest days.

• REPLAY: The Science of New Year's Resolutions (And Why 91% Fail) 01.01.2026 1j 8mnt

  Encore presentation—ad-free! Support independent, evidence-based nutrition content on Patreon for bonus episodes, Q&As with Kylee, and our full archive.Every January, gyms overflow and 91% of resolutions get abandoned before spring. In this episode, we trace the surprisingly ancient history of New Year's resolutions—from Babylonian harvest promises to Roman offerings to Janus—and explore why our brains are so bad at sustaining behavior change.We debunk the myth that habits take 21 days to form (it's actually 18 to 254 days), explain why willpower is one of the least effective tools for lasting change, and dig into the neuroscience of why your cortisol-flooded prefrontal cortex might be working against you. Kylee breaks down the resolution patterns she sees in her nutrition practice—the athlete trying to drop 20 pounds in four weeks, the five-hour Sunday meal prep plans, the all-or-nothing thinking that turns one missed day into total abandonment—and shares how to set goals that actually stick.We cover Strava's "Quitters Day" phenomenon (January 19th), why dry January might backfire, and why positive reinforcement beats self-punishment every time. Plus: Woody Guthrie's charmingly chaotic 1943 list of "New Year's Rulin's," including "wash teeth, if any" and "help win war / beat Fascism."
• Detoxes, Toxins, and Cleanses: The Science (and the Scam) 24.12.2025 1j 20mnt

  Do detoxes work? Do you need a juice cleanse to "reset" your body? Is your liver full of toxins? Short answer: no, no, and absolutely not.This week we debunk the $6.3 trillion wellness industry's claims,juice cleanses, detox teas, foot pads, coffee enemas, the Master Cleanse, and everything in between. We cover how your liver actually detoxifies, why your kidneys filter 200 quarts of blood daily without any help from celery juice, and what a 2015 systematic review concluded about the science of detoxes.We also dig into the history, from ancient Greek bloodletting to George Washington's death to John Harvey Kellogg's yogurt enemas (ew?) and the psychology of why we fall for purity narratives. Plus: why athletes are prime targets, the connection between "clean eating" and orthorexia, documented harms (kidney failure, electrolyte imbalances, rectal perforations (again, EW!)), and 8 red flags for spotting detox scams.95+ facts checked, 17 sources cited.

  The skincare industry is worth over $180 billion globally. The science backing most of it? Let's just say your liver isn't the only organ that doesn't need a detox.This episode is sponsored by Osmia, Science-backed skincare formulated by a physician who actually reads PubMed. Use code YDS20 for 20% off your first order at osmiaskincare.com.This week we're doing something a little different: a partner episode with Osmia, one of our sponsors this season. But if you know YDS, you know we don't do puff pieces. Dr. Sarah Villafranco is a board-certified emergency medicine physician who left the ER to formulate skincare, and brought her doctor brain with her. She's here because she shares our allergy to pseudoscience, not because she's paying us to be nice—and we approached this conversation with the same critical lens we'd bring to any industry deep-dive. (You can read more about how we handle sponsorships and editorial independence at yourdietsuckspodcast.com/our-advertising-ethics-policy.)We talk about why tallow is the new wellness grift (sorry, ancestral girlies), what "natural" actually means when the FDA doesn't regulate it, and why your 20-step TikTok routine is probably making your skin worse. Sarah breaks down the three products that actually matter, explains why thicker doesn't mean more hydrating (remember: hydrate has "water" in it), and makes the case for the least sexy skincare advice ever spoken aloud: consistency.We also get into the ethics of beauty marketing, why "anti-aging" language is completely absent from everything Osmia does, and how to be your own N of 1 experiment when it comes to your skin, which should sound familiar if you've been listening to this show.Plus: the St. Ives Apricot Scrub accountability moment we all needed, why medicated lip balms are a scam, and the skincare equivalent of taking 500 supplements a day.If you've ever felt overwhelmed by serums, confused by "clean beauty" claims, or suspicious that the wellness industry just found a new way to sell you a crisis and then the cure, this one's for you.

We break down what the research actually says about "ingestible beauty" (and, crucially, who funded it), why high-dose biotin might give your doctor an unwelcome surprise, and the psychology of why we keep buying products that promise to fix us from the inside out.Also on the docket: the rise of "preventative Botox" among people under 30, the gut-skin axis (real science, grifty applications), and what actually supports skin, hair, and nail health, spoiler, it's boring.

• Unpacking the Paleo Diet 26.11.2025 1j 9mnt

  Support us on Patreon, and see our full list of references on our website!Do you need to eat like a caveman to unlock your ancestral potential? Spoiler: no, and also, which caveman? The whole premise falls apart the second you ask a follow-up question.This week, we're taking on the Paleo Diet, not just what it says you should eat, but why it exists in the first place. Turns out the history goes way deeper than CrossFit bros and beef sticks. We trace the roots of "ancestral eating" back to 19th-century wilderness cults, Gilded Age masculinity panic, and a 1975 diet book with...some pretty dark roots. From there, we dig into why Paleo took off in Silicon Valley and the manosphere, how it became a $500 million industry selling you a return to nature via Amazon Prime, and what the research actually says about eliminating grains and legumes. Spoiler: your gut bacteria are not thrilled.Kylee breaks down the science on whole grains, the microbiome, and why the "mismatch hypothesis" doesn't hold up to evolutionary scrutiny. Zoë gets lost in Paleo subreddits, finds some surprisingly chill Burning Man content, and connects the dots between diet ideology, gender anxiety, and consumer capitalism.If you've ever wondered why some guy at your gym is very passionate about seed oils, this one's for you.This episode is brought to you by:Janji — Up to 30% off sitewide through December 1st.

Starting at just $3/month.Do you really need that $5 mojito-flavored electrolyte packet to survive your morning Zoom meeting? Spoiler: probably not.This week we're talking salt. From ancient Romans literally getting paid in it to the absolute shitshow that was the 1904 Olympic marathon (two water stations for 26 miles—Google it). Kylee breaks down what electrolytes actually are and who actually needs supplemental sodium (endurance athletes sweating buckets) versus who doesn't (everyone sitting at a desk).We cover sweat tests, sodium replacement strategies, and the deeply annoying fact that the symptoms of too much sodium and too little sodium are basically identical. Plus: the explosion of boutique electrolyte brands, IV drip bars, and why everyone has an emotional support Stanley cup. The wellness industry wants to sell you a crisis and then the cure, and electrolytes are having a serious moment.This episode is brought to you by:Osmia – Science-backed skincare.

From the creation of the first dietary guidelines to the low-fat craze that reshaped grocery store shelves, we unravel how government agencies, industry lobbyists, and “expert” committees turned nutrition advice into a political negotiation.​Tailwind → tailwindnutrition.com, code YOURDIET20 = 20% off first order.​Janji → janji.com, code YDS = 10% off first order.​Microcosm Coaching → ⁠⁠microcosm-coaching.com⁠⁠, book a free consultation call.We talk about how the USDA’s dual role, both promoting agriculture and protecting public health, set the stage for decades of conflict, and how the sugar and processed food industries learned to play the game better than anyone. It’s a story full of backroom deals, scientific sleight of hand, and the kind of marketing spin that turned “moderation” into the most profitable word in nutrition.Thanks to Janji for supporting YDS!

• Relative Energy Deficiency in Sport Explained: Causes, Symptoms, and How to Recover from REDs 15.10.2025 1j 35mnt

  Support us on Patreon!⁠⁠Want to help with a book project? Share Your Story⁠⁠Get YDS tees, mugs, hats and more on Tee Public!This week, Zoë and Kylee dig into one of the most misunderstood topics in endurance sports: RED-S, Relative Energy Deficiency in Sport. We break down what it actually is (spoiler: it’s not just “overtraining”), how to recognize early warning signs, and what the latest science says about recovery.From the old-school concept of the female athlete triad to the 2024 “Does RED-S Exist?” paper, we trace how the conversation around under-fueling has evolved, and why so many athletes are still falling through the cracks. We’ll unpack how RED-S affects everything from hormones and metabolism to bone density, mood, and performance, and why it doesn’t just happen to women or elite runners.This episode separates evidence from internet rumor and offers real talk on what it takes to recover: eating enough, resting enough, and understanding that being tired, cold, and cranky isn’t “just part of training.” Whether you’re an endurance athlete chasing PRs or someone just trying to feel good in your body again, this one’s for you.​Tailwind → tailwindnutrition.com, code YOURDIET20 = 20% off first order.​Janji → janji.com, code YDS = 10% off first order.​Microcosm Coaching → ⁠microcosm-coaching.com⁠, book a free consultation call.
