  • How Environmental Toxins Are Destroying Your Health - The Best of PDL
    Feb 26 2026

    Tired of the status quo health advice? Discover why traditional medicine isn't enough and how you can take control of your health today. This episode is a compilation of the most compelling conversations with guest experts Del Bigtree, Jay Campbell, JP Sears, Joe Polish, and Dr. Nathan Goodyear.

    Mark and these experts explore how factors like environmental toxins, food quality, and lifestyle choices are contributing to a weakening society, with reduced testosterone levels and increased rates of chronic illness, including cancer and autoimmune diseases. They explore the importance of addressing root causes and how biohacking tools can help mitigate these issues.

    The conversation also addresses the rise of self-improvement and empowerment among individuals, particularly fathers, as they step into their roles with newfound purpose. Each guest shares insights on how people can take charge of their health rather than relying solely on pharmaceutical treatments. It's a call to embrace functional and integrative medicine and optimize the body for longevity.

  • The Hidden Cause of Cancer Most Doctors Ignore With Dr. Christy Kesslering
    Feb 19 2026

    Cancer may not start where most people think, and the first treatment might not have to be a drug. In this episode, Mark Young interviews radiation oncologist turned metabolic health practitioner Dr. Christy Kesslering to explore a radically different view of cancer: not as purely genetic bad luck, but as a metabolic and mitochondrial problem.

    Together, they discuss why simply cutting calories or relying on medication isn’t enough and how modern habits damage mitochondria. The conversation also covers ketogenic nutrition, fasting around therapy, sleep, toxins, and how optimizing metabolic health may improve treatment tolerance and outcomes.

    The episode ultimately reframes cancer as a signal — a “check engine light”—and emphasizes patient empowerment. Instead of choosing between conventional or alternative care, Mark and Dr. Kesslering explain how combining approaches and supporting the body’s terrain can dramatically change the trajectory of chronic disease.
