1. Introduction to Dr. Valter Longo

Rich Roll welcomes Dr. Valter Longo for his third appearance on the podcast. Dr. Longo is a renowned researcher in longevity, fasting, and age-related diseases, recognized as one of Time magazine's 50 most influential people in healthcare. He serves as the director of the Longevity Institute at USC, a professor of gerontology and biological sciences, and leads the Longevity and Cancer Program at the Institute of Molecular Oncology in Milan, Italy.

[03:23] Rich Roll: "Returning for his third appearance on the podcast, I'm very pleased to welcome back Dr. Valter Longo..."

2. Impact of NIH Funding Freeze

The conversation begins with a discussion about the temporary freeze on NIH grant review panels, a decision made during the Trump administration. This has caused concern among scientists reliant on NIH funding for essential research.

[06:49] Dr. Valter Longo: "We're very worried... This is a big problem."

Key Points:

• NIH allocates approximately $47 billion, crucial for a wide range of research beyond pharmaceutical studies.
• Dr. Longo emphasizes the importance of NIH funding in supporting clinical trials and translational science, especially for diseases that lack pharmaceutical interest.

3. Advances in Fasting and Longevity Science

Dr. Longo highlights recent advancements in fasting research, particularly focusing on time-restricted eating and the fasting mimicking diet (FMD). He explains the benefits of a 12-hour fasting window as a safe and effective approach to improve health outcomes.

[10:16] Dr. Valter Longo: "At least in my opinion now the more clear evidence for fasting is in the time restricted eating domain."

Key Points:

• A 12-hour fasting window (e.g., eating between 8 AM and 8 PM) aligns with historical eating patterns of centenarians.
• Research indicates that reducing the eating window can enhance metabolic switches, increase energy expenditure, and improve sleep quality.

4. The Fasting Mimicking Diet (FMD)

Dr. Longo delves into the specifics of the FMD, a plant-based, low-calorie, low-sugar, and low-protein diet designed to mimic the physiological effects of water-only fasting without its associated challenges.

[14:02] Dr. Valter Longo: "The fasting mimicking diet was about can we get the same effects as this phenomenal effects that calorie restriction has been demonstrated to have."

Key Points:

• FMD cycles typically last five days and can be repeated every few months.
• Clinical trials show promising results in disease prevention and treatment, including diabetes and kidney disease.
• FMD promotes stem cell activation and metabolic switching, aiding in tissue regeneration and reducing inflammation.

5. Diet Composition and Longevity

The discussion shifts to the role of daily diet in healthspan and lifespan. Dr. Longo emphasizes the importance of amino acid profiles over merely protein intake, advocating for a pescatarian, plant-based diet.

[19:38] Dr. Valter Longo: "What do you eat every day is going to have a huge impact on your health span and lifespan."

Key Points:

• Differentiates between plant-based and animal-based proteins, highlighting the significant variations in amino acid compositions.
• Low but sufficient amino acid intake is crucial for reducing aging markers like IGF1 and leptin.
• Emphasizes personalized diets to account for individual sensitivities and genetic factors.

6. Protein Intake Debate

Contrasting views on protein intake are discussed, particularly the balance between maintaining muscle mass and reducing aging processes. Dr. Longo challenges the notion that higher protein intake is universally beneficial, especially concerning aging and longevity.

[64:43] Dr. Valter Longo: "It's pretty clear that you don't need a lot of proteins. Right."

Key Points:

• High protein diets may accelerate aging by increasing growth factors that drive aging processes.
• Plant-based proteins are favored over animal-based proteins due to their favorable amino acid profiles.
• The optimal protein intake varies with age, suggesting higher needs earlier in life and lower needs in later years.

7. FMD in Cancer Treatment

A significant portion of the discussion revolves around the application of FMD in cancer therapy. Dr. Longo shares insights from clinical trials indicating that FMD, when combined with traditional treatments like chemotherapy and immunotherapy, can enhance remission rates and overall survival.

[92:57] Dr. Valter Longo: "The fasting mimicking diet is making survival better, making also the pathological response better."

Key Points:

• FMD has shown to nearly double remission rates in certain breast cancer patients compared to chemotherapy alone.
• Animal studies demonstrate that FMD can significantly reduce tumor growth and enhance the efficacy of cancer treatments.
• Emphasizes the need for personalized and carefully monitored applications of FMD in cancer patients to avoid potential adverse effects.

8. The Role of AI in Longevity and Healthspan Extension

The conversation touches on the potential and risks of Artificial Intelligence (AI) in advancing longevity science. While Dr. Longo acknowledges AI's capability to streamline research, he also expresses concerns about the uncontrolled evolution of AI systems.

[112:34] Dr. Valter Longo: "I'm very scared of AI, so I don't like it at all."

Key Points:

• AI could accelerate the identification of cancer escape pathways and the development of targeted therapies.
• Dr. Longo warns about the unpredictable evolution of AI, drawing parallels with biological evolution that can lead to unintended consequences.
• Advocates for stringent regulation to harness AI's benefits while mitigating its existential risks.

9. Practical Advice and Future Directions

Dr. Longo offers guidance for individuals facing chronic diseases or obesity, emphasizing a comprehensive approach that includes the longevity diet, FMD, time-restricted eating, and exercise. He also discusses the importance of personalized treatment plans and collaboration with healthcare professionals.

[36:27] Rich Roll: "If somebody's really like in a, you know, like a really acute unhealthy state?"

Key Points:

• Encourages gradual adoption of dietary changes to ensure sustainability and adherence.
• Highlights the role of specialized dietitians and multidisciplinary teams in implementing effective treatment protocols.
• Stresses the potential of FMD in disease reversal, particularly when conventional treatments are ineffective.

10. Conclusion and Resources

The episode concludes with Dr. Longo promoting his book, Fasting Cancer, and directing listeners to his foundation and social media for more information.

[121:38] Dr. Valter Longo: "Professor Valter Longo on Instagram and also the Create Cures foundation. That's, you know, createcurious.org."

Key Takeaways:

• Fasting, particularly the FMD, holds significant promise in extending lifespan and improving disease outcomes.
• Personalized nutrition and lifestyle interventions are crucial for maximizing healthspan and longevity.
• Ongoing research and clinical trials are essential to fully understand and harness the benefits of fasting in medical treatments.
