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?!?

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.

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!

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.

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).

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.)

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.
