16,000 Calories Later: The Science & Physiology of Ultra Endurance with Dr. Andrew Creer

·1 hr 5 min·4 clips

The runners finished in just over 32 hours and burned almost 16,000 calories.

The episode opens with Kyla Chanel setting the tone: science first, hype later. She explains her work in performance nutrition, especially around sex differences in sport, and reminds listeners that the podcast is educational rather than medical advice. From there, the episode moves into ultra-endurance physiology. Kyla and her guest unpack a study that followed two runners over a little more than 32 hours, with the pair finishing together after pacing each other through the effort. That coincidence mattered because it let the team compare two athletes under similar race conditions. The discussion keeps circling back to energy expenditure, because the runners ended up close to 16,000 calories over the event. They also compare the athletes' body weights, since one started around 75 kilos and the other around 60 kilos. The episode lingers on the measurements because the similar values in two different people make the result more interesting. A second thread runs through the race data: the practical problem of wearable tech. Both Garmin devices failed before the finish, which meant the team lost the watch comparison they hoped to make. The conversation also reflects the show's habit of cutting through social-media noise. Kyla says she feels a duty to share real information because misinformation is everywhere. The end of the episode turns outward again. She mentions staying active on Instagram and Facebook and points listeners toward the newsletter and website for more updates. The overall feel is warm, inquisitive, and practical. It sounds like an endurance nutrition consult recorded for a wider audience. Listeners get the story, but they also get the numbers that make the story useful. That balance is what gives the episode its value.

The episode centers on an ultra-endurance race study, with Kyla Chanel returning again and again to the race-day numbers. Two runners finished in just over 32 hours and burned almost 16,000 calories, and the discussion stays close to body weight, calorie expenditure, and the…
