Episode 32: Low-Carbohydrate Performance and Ultrarunning with Zach Bitter

June 21, 2021

In this episode of Science & Chill, I interview ultra-endurance runner Zach Bitter.

Zach is the previous world record holder in the 12-hour run on the track and the 100-mile run on the track (which he actually ran in the same race). He also holds the world record for the fastest 100 miles run on the treadmill. In this episode we talk about these records and put them into perspective, so you all will get an idea of how fast he is running these insane distances. 

Zach is also a fascinating guy because he is interested in the nuances of metabolic health and performance. He is famously known as the “low carb endurance runner” in nutrition and running circles. Through his appearance on the Joe Rogan podcast and affiliation with the carnivore doctor Shawn Baker, Zach has gained a reputation as someone who thrives on a low carbohydrate diet. This is the main thing I wanted to talk to Zach about — what he actually eats, how he structures nutrition and thinks about fueling, and some of the nuances surrounding low-carb diets when it comes to optimal human performance.
