Join our Patreon and get access to monthly bonus episodes and more nutriton content!Can fasting really slow aging? Does calorie restriction work for humans, or just for mice and yeast? And how much protein do you actually need to age well? This week on Your Diet Sucks, we break down the evidence behind the most talked-about interventions in the longevity space, what holds up under scrutiny, what doesn't, and why you might not need a supplement stack to live longer, and enjoy life. We dig into:The actual science on calorie restriction, fasting, and supplements—and where the evidence stopsWhat inflammation, oxidative stress, and telomeres have to do with how we ageThe best-researched dietary patterns for living longer (hint: it's not sexy, but it might include red wine)Why protein becomes more important as we ageThe difference between lifespan and healthspan, and why quality of life needs to be part of the conversation

We cover nutrition claims, pesticide exposure, antioxidant levels, and whether organic food impacts inflammation, gut health, or performance. We also dive into the environmental trade-offs of organic farming, the high cost of certification, and why that $19 strawberry feels morally superior.

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 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.

What happens when the pressure to perform collides with the pressure to look a certain way? 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.

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.

Zoë and Kylee dive into the science, myths, and psychology behind habit formation—and why your January goals are destined to flop without a game plan.

Join the Feisty Fueled Challenge! Sponsored by Microcosm Coaching and Fly Nutrition. Happy New Year! It's the season of crash diets and bad advice, so we're here to cut through the noise with evidence-based answers to your nutrition questions. In this episode, we're covering: How to pick the best protein powder (and why Kylee has a lot of opinions). The secret to knowing if you're eating enough without counting calories. Tips for finding the right gel without losing your mind. How to challenge bad diet advice when you hear it. Does compression therapy actually work, or is it a scam?

Start your year off with smarter fueling and real talk—no BS, no quick fixes, just sustainable solutions that work.

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.

Ask Kylee and Zoë Anything! We're looking for listener questions for an "Ask Us Anything" episode in the New Year! Follow us on the 'gram. In this episode, Kylee and Zoë dive unpack the history of superfoods and why the term might have more to do with marketing than science (spoiler alert, I guess?). We debunk some popular superfood myths and examine the downsides of being hyper-reliant on any one food or ingredient when it comes to maximizing health and performance. Then, we walk through the foods with a strong base of evidence for improving athlete performance and adaptations. Plus, some spicy takes about bananas. Checkmate, atheists!

Kylee and Zoë dive deep into the culture and science of biohacking, from cold plunges to Bulletproof coffee to see why we're all obsessed with the idea that "one weird trick" can have huge results. We unpack where the idea of biohacking came from, and how it has become a major factor in many athletes, especially men's diets. We'll look at some studies that show how the trend is feeding into many men's disordered relationships with food, and ask the question: is biohacking just another way for dudes to mask disordered eating under pseudoscience?

Take Our Audience Survey! This podcast is supported by Microcosm Coaching and Fly Nutrition.  Does tracking your sleep, steps, and nutrition actually make you healthier? In this episode of Your Diet Sucks, Kylee and Zoë dive into the research on when activity trackers help and when they might hurt your health. Whether it's orthosomnia or jogging laps around the parking lot, we examine how the quest for optimization can undermine your well-being and how obsessively tracking your metrics and stats can actually lead to worse health outcomes - and even bad sex?!?

YDS is supported by Microcosm Coaching and Fly Nutrition. How influential are influencers, anyway? Studies show that the folks we interact with (or don't!) virtually on social media can have a real impact on our mental and even physical health.  From ancient Roman gladiators shilling olive oil and wine to today's #fitspo influencers shilling supplements and diet hacks, everyone has the capacity to be influenced. In this episode of Your Diet Sucks, Kylee and Zoë unpack why misinformation spreads so quickly online, who is the most susceptible to influence - and the potential harms that mindless scrolling through idealized and heavily doctored images can have on athletes.

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.

Kylee and Zoë dive into the Wild West of supplementation for athletes. We unpack the history of how athletes have been trying to gain an edge since the very first Olympics (with figs!) and how a lack of regulation makes it tough to know what substances are backed by evidence and what supplements belong in a gas station bathroom. We discuss what athletes should know about contamination and competition and what questions everyone should ask themselves if they're considering taking a supplement. Plus - the many uses of Horny Goat Weed!

If you or someone you know is struggling with an eating disorder, help is available. Reach out here.  At least 30 million Americans have an eating disorder, but only 1 in 10 people gets the treatment they need. Why? Kylee and Zoë debunk common myths about eating disorders, from who they affect to how they're treated. We dive into the history of eating disorders and how common misbeliefs about mental illness shape their treatment today. We examine how weight stigma impacts treatment and why so many EDs are considered “atypical.” Then, we offer some practical solutions for fixing a f*cked-up system by debunking common misconceptions.  REFERENCES: Kazdin, C.

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!). We also discuss common and uncommon causes of GI distress and what athletes can do to support their gut health (spoiler alert: you probably don't need all that kombucha). Yong, E. (2018).

Zoë and Kylee break down why diets feel so...culty lately. From Paleo bros to Keto fanatics, we dive into why people are drawn to rigid ways of eating, and how to know if you just might be in a diet cult yourself!

In this episode, Kylee and Zoë explore the complicated history that humans have with alcohol and athletics. We dive into the deep past (shoutout to our simian ancestors!) and see why scientists think humans developed a taste for something that seems counterproductive to passing on our genes (looking at you, Smirnoff blue raspberry). We try to parse out why alcohol is so closely tied to endurance sports and take a deep dive into what the research says about this substance (spoiler alert: three shots of whiskey do NOT make you better at running on a treadmill.)

Would you run 100 miles with zero calories? Should you? In episode two, we break down the history - and the science - of fasting. We dive into why athletes seem drawn to a mentality of doing more with less fuel and the potential benefits of fasting compared with the downsides.

Welcome to episode one! Get to know hosts Kylee Van Horn and Zoë Rom and why they're endlesslessly fascinated with food. In this episode, we ask why athletes seem so prone to diet bullsh*t and pseudoscience. We discuss how social media has hastened the spread of pseudoscience and why “experts” tend to overstate their experience. We conclude with a discussion of Bullsh*t Red Flags to help you identify diet nonsense in the wild.  References: Melin A., Tornberg Å.B., Skouby S., Møller S.S., Sundgot-Borgen J., Faber J., Sidelmann J.J., Aziz M., Sjödin A.
