Lab Rat Radio
Lab Rat Radio is a long-form conversation about human physiology, nutrition, exercise science, and evidence-based health. Hosted by lifelong lab rats and current university professors Dr. Emily Dow and Dr. Nathan Jenkins, the show bridges research, teaching, coaching, and real-world application. Topics include metabolism, fueling for performance, hormones, gut health, training adaptations, and supplements. The podcast aims to separate scientific evidence from online exaggerations for curious listeners.

Gut Health 101 and Dr. Emily's Dissertation Research
In this episode, we unpack what “gut health” actually means, from symptoms, motility, digestion, and the microbiome to intestinal barrier function, immune signaling, gut-brain communication, and exercise-related GI distress.

In this episode, we use the case of an athlete who is afraid to fuel to explore the large overlap between performance nutrition and body composition nutrition. We talk energy balance, carbohydrates, protein, recovery, low energy availability, and why under-fueling can make both performance an
Introduction to Lab Rat Radio
