Would you run 100 miles without eating? Some athletes have tried — but should you?

In this episode of Your Diet Sucks, we explore the history and science of fasting for endurance athletes. From early experiments in “train low” strategies to the modern hype around intermittent fasting, we dig into why runners and athletes are drawn to the idea of doing more with less fuel. We break down the potential benefits of fasting — fat adaptation, metabolic flexibility, and simplicity — alongside the risks and downsides, like reduced performance, higher injury risk, and impaired recovery.

If you’ve ever wondered whether fasting can actually help your running or if it’s just another diet trend, this episode gives you the evidence-based answers.

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.
