Unpacking Ultra-processed Foods
Follow us on Instagram @yourdietsuckspod!This week, Kylee and Zoë take a deep dive into ultra-processed foods: what they are, where they came from, how they’re designed to light up your brain’s reward systems, and what role they play in athletic nutrition. 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.

Your Nutrition Documentary Sucks.
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.

Body Image Bulls*ht, Fitness Culture, and Athletes

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especially vulnerable.From social media-fueled comparison traps (looking at you, Facetune) to toxic fitness culture and outdated coaching methods, we explore why so many athletes struggle with body image—and what actually helps.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.

Your Sports Nutrition Marketing Sucks.
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!

Make America Healthy, Actually
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.
