    Kylee and ZoĂ« 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!

    · Your Diet Sucks

    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.

    Ep. 1 - Why Athletes Fall For Diet Bullsh*t

    · Your Diet Sucks

    Welcome to episode one! Get to know hosts Kylee Van Horn and ZoĂ« 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.
