In this special Q&A episode, Dr. Jason Fung joins TFM Coach Lisa and Community Mentor Patrice Michael to revisit The Cancer Code — five years after its release. Together, they explore how modern science is reframing cancer not as a disease of random genetic "bad luck," but as an evolutionary and metabolic condition deeply connected to insulin, diet, and lifestyle.
Dr. Fung explains how hyperinsulinemia, obesity, and processed foods create fertile "soil" for cancer to grow — and how fasting and nutritional strategies can help restore metabolic balance. He also discusses the link between hormones and cancer risk, new non-radiation screening technologies, and how combining traditional treatments with metabolic interventions may shape the future of cancer care.
Episode #231
🧭 Listener Questions Include:
- What does current research say about fasting's potential role in cancer prevention, particularly for individuals with family histories of cancer?
- How do insulin, IGF-1, and mTOR influence cancer risk — and what information exists comparing ketogenic versus plant-based diets for prevention and overall health?
- For someone with a significant family cancer history (including aggressive cases in young adults), what non-radiation screening or imaging technologies are available?
- Do bioidentical hormone replacement therapies increase cancer risk, and can fasting help reduce that risk?
- What's your view on combining traditional treatments with metabolic interventions?
- Can you tell us about your upcoming book, The Hunger Code?
- If the cancer research community fully embraced your paradigm, what would be the top three research priorities?

💡 Key Takeaway
"Cancer isn't just a disease of bad luck — it's a disease of metabolism. By changing the soil through fasting and nutrition, we can change the outcome."
