Location: Mobile, Alabama
Episode Theme: How personalized data and preventive medicine are reshaping modern healthcare.

In this episode, David sits down with Dr. Grant Zarzour, a board-certified orthopedic surgeon who performs over 650 joint replacements each year, and the founder of Sperity Health—a cutting-edge longevity and health optimization company based in Alabama.

Dr. Zarzour shares how years in the operating room inspired him to move upstream—focusing not just on repairing joints, but on preventing disease and optimizing human performance through data-driven, personalized care.

Together, they unpack what “Medicine 3.0” really looks like in practice and how Sperity is empowering clients to take control of their health with measurable results.

1. Sperity’s Mission & Medicine 3.0

Dr. Zarzour explains how “Medicine 3.0” represents a shift from reactive treatment to proactive, precision-based health optimization, where doctors become health coaches rather than crisis responders.

2. VO₂Max Testing & Longevity

Often thought of as an athlete’s metric, VO₂Max is one of the strongest predictors of lifespan. Dr. Zarzour breaks down why Sperity tests this for every client and how improving cardiovascular efficiency can literally add years to your life.

3. GLP-1 Therapies & Metabolic Health

While GLP-1 medications like semaglutide have gained massive attention for weight loss, Dr. Zarzour shares a balanced view—when they can be helpful, who benefits most, and why long-term metabolic health must remain the goal.

4. Sleep as a Foundational Pillar

Sperity treats sleep as one of the most underappreciated drivers of recovery, performance, and hormone balance. Dr. Zarzour outlines how they assess and improve sleep quality using technology, environment design, and behavior tracking.

5. Data, Testing & Early Detection

From MRI scans and deep blood panels to wearable devices, Sperity uses a full spectrum of diagnostics to uncover issues early—and turn complex data into clear, actionable health roadmaps for each member.

6. Measurable Outcomes

Dr. Zarzour highlights real-world results—improved body composition, cardiovascular capacity, inflammation markers, and longevity scores—that demonstrate how a personalized, whole-person approach to medicine produces lasting change.

7. The Future of Health Optimization

Looking ahead 5–10 years, Dr. Zarzour shares his excitement about AI-driven predictive health, continuous monitoring, and the growing collaboration between medical specialists, coaches, and technologists.

• VO₂Max is the new cholesterol — the single most powerful metric for longevity.

• Sleep optimization isn’t optional; it’s foundational.

• GLP-1s can be a tool, not a crutch, when combined with lifestyle interventions.

• Medicine 3.0 is data-driven, preventive, and personalized.

• Health optimization should feel like coaching — not clinical care.
