Your Diet Sucks

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!

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.
