Your Diet Sucks

Get "Carb Slut" and "Petty and Scientifically Literate" merch here!Whole30 has sold millions of books, built a coaching empire, and partnered with Chipotle and Walmart — all without a single peer-reviewed clinical trial. In this episode, Zoë traces the program from its origin on a CrossFit blog in 2009 to its multi-million dollar licensing ecosystem, digs into the loaded vocabulary (sugar dragons, tiger blood, sex with your pants on), and examines what happened when a nutrition science student fact-checked all 450 citations in It Starts With Food. 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.

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

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.

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.

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.

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."

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.

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.

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.

Support YDS on Patreon!This week, Zoë and Kylee tackle the carnivore diet, the internet’s most extreme eating trend. From raw liver smoothies at Erewhon to shirtless influencers promising that “meat heals everything,” the carnivore diet has exploded in popularity. But what really happens when you cut out all plants and live on ribeye steaks, bacon, and bone broth?We explore the strange history of meat-only diets, from 1920s Bellevue experiments to modern influencers like Shawn Baker and Paul Saladino. We unpack the claims about plant “toxins,” the allure of ketosis, and why athletes, especially women, need carbs for performance, recovery, and hormone health. And we dig into the environmental cost of ribeye-heavy eating, why beef is one of the most resource-intensive foods on the planet, and how climate denial often gets wrapped into carnivore culture.So should you go full T-Rex? Probably not. But understanding the hype—and the risks—shows why restrictive food fads keep spreading, and why carbs are still essential for endurance athletes and long-term health.Support the ShowEternal – To check out Foundations, use the promo code YDS for 10% a one year membership.Tailwind Nutrition offers science–backed endurance fuel that actually works.
