  Gut Health 101 and Dr. Emily's Dissertation Research 18.08.2026 1год 26хв

  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. Emily walks us through her dissertation research on resistance training, mood state, and intestinal permeability, and we use a case study to talk through bloating, fiber tolerance, probiotics, gut repair supplements, and why symptoms do not automatically mean your gut is broken.

  Cortisol: The Internet's Favorite C-Word 11.08.2026 1год 14хв

  Cortisol has become the wellness world's favorite scapegoat: blamed for belly fat, fatigue, poor sleep, training plateaus, and basically every difficult season of life. In this episode, we unpack what cortisol actually does, why acute rises with exercise, food, waking, fasting, and stress are often normal, and when cortisol patterns may genuinely reflect chronic dysregulation or clinical concern. We also discuss under-fueling, sleep restriction, training load, caffeine, cortisol testing, "adrenal support" marketing, and why the better question is usually not "How do I lower cortisol?" but "How do I manage my overall stress load?". Cortisol is not the villain. Bad explanations are.   This episode is sponsored by MacroFactor, a premium nutrition app that combines fast food logging with adaptive nutrition coaching.

  Fueling for Performance vs. Body Composition 04.08.2026 1год 25хв

  Do you want to perform well, or do you want to be lean? The internet loves forcing that binary. We do not. 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 and fat loss harder. Fueling is not reckless eating, and dieting is not supposed to mean feeling terrible all the time.
