Gut Training for Athletes with Dr. Roxanne Vogel - Ep. #223

from Inside Sports Nutrition · host Bob Seebohar and Dina Griffin

Is more carbohydrate always better, or does your gut need to be trained like your legs?In this episode, we sit down with Roxanne Vogel, PhD, Director of Research and Education at GU Energy Labs, to unpack what gut training actually means, how carbohydrates use different transport systems, and why carbohydrate tolerance varies so much between athletes. We also explore the "why" behind gut training, high carb feeding, metabolic flexibility, the role of hot environments, and what personalized carbohydrate strategies may look like in the near future.More about our guest:Roxanne Gonzales Vogel is a scientist, athlete, and adventurer. As the Director of Research and Education at GU Energy Labs, she oversees the brand’s Performance Lab and works with elite athletes to optimize nutrition for performance, health, and longevity. She holds a PhD in Exercise Physiology from Southern Cross University in Australia, where her research focused on environmental physiology and strategies to improve athletic performance in the presence of environmental stressors, including heat, cold, and hypoxia. Roxanne’s research interests are largely inspired by her pursuits as a high-altitude mountaineer and ultra-endurance athlete. In May of 2019, she summited Mount Everest in a fraction of the time it normally takes—two weeks as opposed to two months— using a novel pre-acclimation protocol and custom nutrition products she developed to make the record-breaking ascent possible. Roxanne is also an experienced trail runner, competing primarily in mountain ultramarathons, including the iconic Leadville 100 where she placed 4th in 2022. She has spent the past 15 years studying nutrition and its impact on body composition, athletic performance, and cognitive function. Roxanne currently lives and trains in Mammoth Lakes, CA.-------Drop a question in our free Patreon Community and get access to bonus content with Bob and Dina by upgrading to the Gold Level membership.
