Your Sports Nutrition Marketing Sucks.
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!

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.

The Reality of Racing Weight
Join the Feisty Fueled Challenge! Kylee and Zoë wade into the murky waters of "racing weight"—a concept that’s been messing with athletes’ heads since the early days of endurance sports. From ancient Greek wrestlers sweating it out in bathhouses to modern-day endurance athletes chewing gum to spit out extra grams (yes, that’s a thing), the obsession with weight and performance has a long, bizarre history. We unpack the origins of this idea, critique the pseudoscience and harmful messaging it often comes with, and dig into why lighter doesn’t always mean faster. Along the way, we examine why weight has become such a fixation in endurance sports and how that obsession can derail not just your performance, but your overall health. Whether you’ve been told you need to hit an “ideal weight” to perform your best, or you’re just curious about why athletes fixate on the scale, this episode is a deep dive into why chasing racing weight can do more harm than good. Spoiler alert: You’re more than your power-to-weight ratio. Tune in for the history, the science, and the many reasons you don’t need a scale to measure your worth—or your speed. Plus, a surprising history lesson involving figs, bloodletting, and why we don’t recommend using Horny Goat Weed to prep for your next race.

Are Superfoods a Scam?
Are superfoods a scam? From açaí bowls to spirulina smoothies to $40 green powders, the "superfood" label has become a $150 billion marketing machine. But most superfood claims are about branding, not science—and the term itself was invented to sell bananas. In this episode, Kylee and Zoë unpack the history of superfoods: how the word went from a 1940s marketing gimmick to a wellness industry obsession. We debunk popular myths, examine the downsides of being hyper-reliant on any single food or ingredient, and walk through what the evidence actually says about foods that improve athletic performance and adaptation. Spoiler: your banana is doing more than that high-antioxidant powder you're spending $60 on. Plus: some spicy takes about blueberries. Checkmate, atheists!

Is Biohacking Just Diet Culture for Men?
Is biohacking just diet culture repackaged for men? From cold plunges and Bulletproof coffee to ice baths and "optimization" spreadsheets, the wellness industry has found a way to sell restriction to dudes by calling it science. In this episode, Kylee and Zoë trace where biohacking came from, why "one weird trick" thinking is so seductive, and how the trend is feeding disordered eating patterns in male athletes—masked as performance enhancement. We dig into the research on whether any of this actually works, why putting your diet in a spreadsheet doesn't make it healthy, and the question nobody's asking: is biohacking just another way for men to control their bodies under the guise of optimization? If you've ever wondered why the guy at your gym is so passionate about seed oils and morning sunlight, this one's for you.

Is Your Fitness Tracker Helping or Hurting?
Take Our Audience Survey! This podcast is supported by Microcosm Coaching and Fly Nutrition. Is your Garmin making you crazy? Whoop, Oura, MyFitnessPal, Apple Watch—activity trackers promise optimization, but research shows they can fuel anxiety, obsessive behavior, and orthorexia in athletes. The line between "data-driven training" and compulsive self-monitoring is thinner than you think. In this episode, Kylee and Zoë dive into the research on when tracking helps performance and when it hurts your health. We explore the psychology of quantification—why we love turning our bodies into spreadsheets—and how the wellness industry profits from making you feel like you're never optimized enough. If you've ever felt guilty for missing your step goal, panicked over a "bad" HRV score, or wondered whether your recovery app is actually recovering anything, this episode will help you figure out where the line is—and whether it's time to take off the watch.

Should You Trust Fitness Influencers?
YDS is supported by Microcosm Coaching and Fly Nutrition. Should you trust fitness influencers? From ancient Roman gladiators shilling olive oil to today's #fitspo accounts pushing supplements, humans have always been influenced—but social media has supercharged it. Studies show the people we interact with online can have real, measurable impacts on our mental and physical health—and athletes are especially vulnerable. In this episode, Kylee and Zoë unpack why health misinformation spreads so fast, who's most susceptible to influence, and the documented harms of scrolling through heavily filtered images and dubious nutrition advice. We trace the history of endorsement culture, break down the psychology of why we trust strangers on the internet, and offer tools to protect yourself without deleting every app. If you've ever felt worse about your body or your fueling after 10 minutes on Instagram, this episode is your antidote.

Orthorexia: When Healthy Eating Becomes Unhealthy
YDS is supported by ⁠Microcosm Coaching. In this episode, Kylee and Zoë dive into the evolving conversation around Orthorexia—a term for an unhealthy obsession with healthy eating. We explore the impact of societal norms, social media, and misinformation on people's relationship with food, particularly athletes. As more people seek to "clean up" their diets, we’re seeing how rigid rules and an obsession with food purity can disrupt lives. We’ll unpack how Orthorexia isn't officially recognized in the DSM but still significantly impacts mental and physical health, drawing from professional insights and research. We also chat through how athletes and active folks can work towards a more balanced approach to nutrition, and avoid the pitfalls of over-restriction. References Conviser JH, Fisher SD, McColley SA.

Do You Actually Need Supplements?
YDS is supported by ⁠⁠Microcosm Coaching. ⁠ Do you actually need supplements? The sports nutrition industry wants you to believe you can't perform without a cabinet full of pills, powders, and proprietary blends. But what does the research actually say—and how do you separate evidence from marketing? In this episode, Kylee and Zoë break down the supplement landscape: which ones have solid evidence behind them (spoiler: it's a short list), which are a waste of money, and which might actually be harmful. We cover protein powders, creatine, BCAAs, greens powders, and the unregulated Wild West of sports supplements—including the heavy metals and unlisted ingredients that sometimes show up in third-party testing. Whether you're wondering if you need to add something to your stack or looking for permission to simplify, this episode will help you make evidence-based decisions without the hype.

Eating Disorder Myths That Won't Die
YDS is supported by ⁠⁠Microcosm Coaching. ⁠ Most people with eating disorders don't look sick—and that's part of the problem. Eating disorders affect people of every size, gender, race, and athletic ability, but myths about who gets them and what they look like keep millions from getting treatment. In this episode, Kylee and Zoë debunk the most harmful misconceptions: that EDs only affect young white women, that you have to be underweight to be diagnosed, that recovery means "just eating more," and that athletes are somehow immune. We trace the history of how eating disorders have been understood (and misunderstood) in medicine, examine how weight stigma impacts treatment access, and explain why so many cases are labeled "atypical"—even though they're actually the norm. Then, we offer practical solutions for fixing a system that's failing the people who need it most. REFERENCES: Kazdin, C. (2023). What’s eating us. St Martin’s Press.

Athletes, The Microbiome and Gut Health
YDS is supported by ⁠⁠Microcosm Coaching. ⁠ Kylee and Zoë take a magic school bus ride into the microbiome! We go back (waaay back) into the origins of the human microbiome and examine the research on how gut biota affects and interplays with athletic performance. Put your gloves on, because we’re digging into Zoë’s microbiome to get to know her on a very, very intimate level (the microbial level!).

When Diets Become Cults
YDS is supported by ⁠⁠Microcosm Coaching. ⁠ What makes a diet become a cult? From Kellogg's sanitarium to modern wellness retreats, the line between "lifestyle" and "indoctrination" is thinner than you'd think. Restrictive eating communities share surprising similarities with high-control groups: charismatic leaders, us-vs-them thinking, purity rituals, and the promise that following the rules will make you special. In this episode, Kylee and Zoë explore the psychology of why diet communities can feel so consuming—and why leaving them can feel like losing your identity. We trace the history of food-based moral systems, examine the tactics that keep people loyal to restrictive eating patterns, and offer tools for recognizing when "wellness" has crossed into something more controlling. If you've ever felt like your diet had become your whole personality—or watched someone you love disappear into a food ideology—this episode is for you.

Is Alcohol Ruining Your Training?
YDS is supported by ⁠⁠Microcosm Coaching. ⁠ Is alcohol ruining your training? From post-race beers to wine with dinner, drinking is woven into athletic culture—but what does the research actually say about how alcohol affects performance, recovery, and long-term health? In this episode, Kylee and Zoë break down the science: how alcohol impacts sleep, hydration, muscle protein synthesis, and hormonal recovery. We explore why athletes drink (spoiler: it's complicated), what "moderate" actually means, and how to make informed decisions without moralizing your choices. Whether you're wondering if that celebratory beer is sabotaging your gains or just want to understand the trade-offs, this episode gives you the facts without the judgment.
