His book, The Longevity Diet, outlines an everyday eating pattern inspired by centenarian populations, combined with periodic FMD cycles.

• Core Principles:
  • Predominantly plant-based, with occasional fish.
  • Low protein intake.
  • Periodic FMD for cellular renewal.

Dr. Andrew Huberman: The Practical Neuroscientist

Dr. Andrew Huberman, a neuroscientist and professor at Stanford School of Medicine, translates complex neuroscience into practical, actionable advice via his Huberman Lab podcast. His approach to longevity centers on optimizing the nervous system and body through foundational, science-backed protocols. Huberman emphasizes the importance of basic pillars of health that impact all biological systems, making his methods accessible to a broad audience.

• Top-Tier "Levers" for Longevity:
  1. Sleep: Prioritizing and optimizing sleep quality.
  2. Light Exposure: Getting morning sunlight and avoiding light at night to regulate circadian rhythm.
  3. Exercise: A consistent mix of cardiovascular and resistance training.
  4. Stress Management: Controlling stress through deliberate practice and lifestyle choices.

Dan Buettner: The Blue Zones Researcher

Author and explorer Dan Buettner offers a population-based perspective on longevity by identifying and studying the "Blue Zones"—geographic areas with the world's highest concentrations of centenarians. His work demonstrates that longevity is not solely dependent on individual biohacking, but heavily influenced by communal, environmental, and lifestyle factors. The Blue Zones project highlights the power of living in a supportive environment with purpose, regular natural movement, and a plant-heavy diet.
