In this episode of Your Diet Sucks, Zoë and Kylee dig into the science, the politics, and the messy cultural baggage around food and the environment. From beef’s outsized carbon footprint to the confusing debates over almond milk vs. oat milk, we break down what actually matters for athletes and active people who want to fuel performance without trashing the planet. We trace the history of meat, dairy, and industrial agriculture, explain why food waste is one of the biggest hidden drivers of greenhouse gas emissions, and talk about whether “grass-fed” beef or “sustainable” seafood really lives up to the hype. Plus, we get real about the politics behind dietary guidelines, the myth of the carbon footprint, and why Fox News thinks burgers are freedom. Spoiler: we’re not here to take away your mozzarella or your post-run burrito, we’re here to help you make sense of the science, push back on diet-culture guilt trips, and show how small, practical choices add up when athletes use their voices for systemic change.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.

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.

In this episode of Your Diet Sucks, Zoë and Kylee dive deep into the history of metabolism myths, from ice chewing and celery diets to vibrating chairs, bulletproof coffee, and the latest TikTok hacks. We break down what metabolism actually is, why you probably don’t need to “hack” it, and what really matters for long-term health and performance. We talk about why spicy food won’t magically melt fat, the truth about cold water, apple cider vinegar, and green tea, and the real factors that impact metabolism, like muscle, sleep, and eating enough. We also dig into how under-fueling and diet culture can actually slow you down.

From adrenal fatigue (not real) to seed cycling (also not real), Zoë and Kylee cut through the pseudoscience and explain what actually supports hormone health—like eating enough, managing stress, and getting some damn sleep. We also take a look at the unhinged history of hormone manipulation (yes, monkey testicle transplants come up), why cortisol isn’t your enemy, and what to do if your hormones actually feel off.

Support us on Patreon!Thanks to Skratch Labs for sponsoring the podcast! Get a free sample pack on us!This week on Your Diet Sucks, we’re digging into one of the most misunderstood—and over-marketed—topics in endurance sports: nutrition for female athletes.You’ve probably heard the myths: women should eat for their body type, avoid carbs during their cycle, or that we're not just small men when it comes to fueling. But most of that advice isn’t based on solid science; it’s based on outdated research, rigid stereotypes, and a whole lot of pseudoscience.In this episode, Kylee and Zoë unpack:​Why most sports science has ignored female athletes for decades​How hormonal fluctuations, birth control, and life stage transitions affect fueling​What’s actually different about female endurance physiology​The truth about somatotypes (ectomorph, mesomorph, endomorph) and why they’re BS​Evidence-backed nutrition strategies for training, recovery, and long-term health​Why research gaps are still being filled by grifters, and how to stay skepticalWhether you're menstruating, on birth control, pregnant, postpartum, or in perimenopause—or you coach or care about someone who is—this episode is your myth-busting guide to what women really need to fuel their performance.Thanks to Janji for supporting the podcast!

We talk about everything from cereal meant to prevent sinning to the low-fat diet craze, the war-time origins of shelf-stable food, and the engineering behind the foods that are hyper-palatable.We also get into the landmark NIH study that showed just how much processing—not just calories or macros—can influence how much we eat, how full we feel, and how our bodies respond to food. This episode is about helping you understand the systems at play, so you can make choices that support your health and performance without getting caught in fear or shame about the food you eat. Because when it comes to ultra-processed foods, context matters—especially for athletes.💥 This episode is fueled by:🧪 Skratch Labs Whether you’re training, racing, or just trying to stay upright during a long day—real ingredients matter.

Support us on Patreon!This week on Your Diet Sucks, Kylee and Zoë take a hard look at health documentaries, specifically the cult classic Game Changers—aka, the boner experiment film—and other nutrition flicks that have people rethinking their entire diet for about a week. They break down why these documentaries always go full fear-mongering mode, how they cherry-pick studies to push an agenda, why they obsess over masculinity and strength, the biggest nutrition myths they keep pushing, and how to actually fact-check food and health claims so you don’t get duped. Plus, Zoë does what she does best: fact-check their questionable science in real-time, rage-Google studies, and ask the real questions—like, who decided we needed a documentary about penis blood flow?Hit play, grab your popcorn (or, I don’t know, a block of cheese like we did), and let’s get into it.SponsorsJanji – The only running shorts we trust, period.

This week, we’re tackling body image in sports and fitness—breaking down the differences between body dysmorphia, body dissatisfaction, and body dysmorphic disorder (BDD), and why athletes are especially vulnerable.From social media-fueled comparison traps (looking at you, Facetune) to toxic fitness culture and outdated coaching methods, we explore why so many athletes struggle with body image—and what actually helps. Plus, a deep dive into why traditional body positivity isn’t the answer and why frameworks like body neutrality, fat liberation, and radical body acceptance are changing the conversation.💥 Spoiler: It’s not your body that’s broken—it’s the system.Resources & Further Reading:📖 The link between social media and body dysmorphia📖 Athletes, disordered eating, and performance pressures📖 How fitness culture reinforces body dissatisfactionShoutout to Our Sponsors!🎉 Big thanks to Tailwind Nutrition and Janji for making this episode possible.

Support us on Patreon!Follow us on Instagram! Your Diet Sucks is back, and today Zoë and Kylee are diving into the Wild Wild West of sports nutrition marketing—where sugar is the enemy, ketones are tactical, and somehow, gels need to be “guilt-free.”In this episode, we break down how sports nutrition marketing plays on fear, misinformation, and diet culture to sell you products that may or may not actually help you perform. We unpack why terms like “guilt-free” are designed to manipulate you (as if your fuel choices require moral absolution), how brands sneak in buzzwords like “clean” or “sugar-free” to stoke carb paranoia, and why influencer culture has turned sports nutrition into a race to see who can make the most dramatic, pseudoscientific claims.We also dig into the science—or lack thereof—behind metabolism-boosting formulas, carb-phobic electrolyte mixes, and products that promise you won’t experience GI distress (bold claim, considering we’ve all been betrayed by a burrito at some point).Hold onto your ketones—we’re debunking, demystifying, and dunking on pseudoscience.So what should you actually look for in a sports nutrition product? We got you. We break down how to separate marketing BS from real science, so you don’t end up under-fueled, overcharged, or spending $5 on a single gram of carbs.Thanks to our sponsors, Janji and Microcosm Coaching!

You came here for nutrition tips and maybe some good-natured dunking on diet fads—not a deep dive into politics. But here’s the thing: food and health are political. And with Robert F. Kennedy Jr. pushing his "Make America Healthy Again" (MAHA) agenda, it's impossible to ignore how his take on fitness, food, and public health is pulling people into his camp. On the surface, MAHA taps into real concerns—ultra-processed foods, chronic disease, corporate influence on health policy. But beneath the slogans, the movement leans hard on personal responsibility while offering little in the way of actual solutions. We’re not here to dunk on anyone for questioning the status quo—critical thinking is good! But when it comes to making America healthy, actually, we need solutions that go beyond slogans.
