Why Zach Bitter Went High Carb After 14 Years of Low Carb Fueling
Episode 131
Thursday, 19 February, 2026
What if the fueling strategy you’ve followed for years is no longer the one that best supports your performance?In Episode 131 of The Eat for Endurance Podcast, I’m joined by elite ultrarunner and coach Zach Bitter for a thoughtful conversation about his experience with both low and high carb fueling.After following a low carb diet for 14 years, including when he broke the World and American Records in the 100-mile distance, he decided to change course and try high carb fueling. It's been 8 months now of experimenting with more carbs, and so far, he’s had a very positive experience.Zach and I discuss:Why he originally went low carb as a younger ultrarunnerWhat his particular flavor of low carb fueling looked like in practiceWhat motivated him to dramatically increase his carb intake last yearHow high carb fueling has influenced his recent training and racingWhy you shouldn't make one single diet your whole identityThe importance of curiosity and flexibility for long-term health and performanceThis episode is full of nuance, and underscores the fact that there is no one-size-fits-all diet. As Zach says in the episode, don't be afraid to try something new, because if it doesn't work out, you can always go back to what you were doing before!🎧 Tune in to learn more!Links & ResourcesFollow Zach Bitter on Instagram and visit Zach’s WebsiteInterested in comprehensive, in-depth 1:1 coaching?
