Dr. Will Bulsiewicz Speaking Topics

Gut Health & Sustainable Performance

High performance shouldn’t come at the cost of long-term health. In this talk, Dr. Will Bulsiewicz (“Dr. B”) explains how the gut microbiome serves as the foundation for sustainable energy, focus, immunity, and recovery—and why so many high achievers unknowingly undermine their performance through chronic inflammation, circadian disruption, and poor gut resilience. Drawing from cutting-edge research and clinical experience, this session connects nutrition, sleep, stress, and the gut–immune–brain axis to show how small daily habits compound into durability over time. Attendees leave with a clear, evidence-based framework for building performance that lasts—without burnout, extremes, or biohacking fads.

Burnout, Energy & Its Gut Origins

Burnout isn’t just psychological—it’s biological, and the gut is often where it begins. In this eye-opening talk, Dr. Will Bulsiewicz (“Dr. B”) reveals how gut inflammation, microbiome imbalance, and a compromised gut barrier quietly drain energy, blunt motivation, and lock people into cycles of fatigue and stress. By unpacking the gut’s role in immune activation, stress hormones, neurotransmitters, and metabolic health, Dr. B reframes burnout as a reversible physiological state—not a personal failure. This session gives audiences a science-backed roadmap to restore energy, calm the nervous system, and rebuild resilience from the inside out.
