Men, Masculinity, Body Image and Disordered Eating
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. When The Rock does it, he's a brand. When your friend does it, check in.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

Detoxes, Toxins, and Cleanses: The Science (and the Scam)
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.

Tallow, Toxins, and TikTok: What Skincare Gets Wrong Partner Episode with Osmia
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.

Are Beauty Supplements a Scam?
Join our Patreon!Get YDS Merch for the holidays!Can you supplement your way to a glow? The $70 billion beauty supplement industry certainly wants you to think so.This week we dig into collagen, biotin, hyaluronic acid, and those $90 greens powders everyone's suddenly drinking, tracing the history from Lydia Pinkham's 19th-century vegetable compound to today's $60 Moon Juice dusts. 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. If you've ever wondered whether that greens powder is doing anything besides lightening your wallet, this one's for you.This episode is brought to you by:Tailwind Nutrition – Sports nutrition without the BS.

Unpacking the Paleo Diet
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.

How Nutrition Guidelines Became Political
Support us on Patreon!Get YDS tees, mugs, hats and more on Tee Public!This week on Your Diet Sucks, Zoë and Kylee dive headfirst into the messy, fascinating world of food policy, the history, politics, and corporate influence that quietly shape what ends up on your plate. 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
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.

Cannabis, Culture, and the Runner’s High
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 on Your Diet Sucks, we’re digging into cannabis, how a plant got tangled up in politics, culture wars, and moral panic, and how that continues to shape the way we study it, regulate it, and talk about it today. We trace the science, the stigma, and the shifting rules, from Harry Anslinger’s racist propaganda campaigns to today’s confusing contradictions (why is cannabis still banned in sport while alcohol isn’t?).We’ll also talk about what current research actually says about cannabis and performance, what gaps remain, and how athletes can think about using it.Eternal → eternal.co, code YDS = 10% off membership.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.
