Here's what hit me hardest: 70% of your immune system lives in your gut, and there's now evidence that dementia might actually start there, not in the brain. We spend two hours diving deep into how your gut bacteria literally text messages your brain (there's one that triggers the same hormone as a passionate kiss!), and Dr. Li revealed the simple changes that can transform your health without expensive biohacking. This conversation changed how I think about longevity. It's not about chasing a number, it's about nurturing the 39 trillion bacteria that determine whether you thrive or just survive.</p><p><a href="https://www.youtube.com/c/drwilliamli" target="_blank">Dr. William Li on YouTube</a></p><p><a href="https://amzn.to/4bxF2lo" target="_blank"><i>Eat to Beat Disease</i> by Dr. William Li</a></p><p><a href="https://amzn.to/41LuprQ" target="_blank"><i>Eat to Beat Your Diet</i> by Dr. William Li</a></p><p>In this episode you will:</p><ul><li>Discover the four specific gut bacteria found in super-centenarians that you can actually cultivate through simple food choices - no expensive supplements required</li><li>Transform your understanding of dementia and brain health by learning how gum disease and gut bacteria might be the hidden triggers we've been missing</li><li>Break through the confusion about processed foods by understanding exactly what happens when they enter your body versus whole foods (Dr. Li's symphony analogy is unforgettable)</li><li>Unlock your body's natural healing systems with Dr. Li's practical 5-step reset plan that costs nothing but can change everything</li><li>Revolutionize your sleep by understanding the glymphatic system - your brain's hidden sewer system that only opens when you get deep sleep</li></ul><p>For more information go to <a href="https://lewishowes.com/1811" target="_blank">https://lewishowes.com/1811</a></p><p>For more Greatness text PODCAST to +1 (614) 350-3960</p><p>More SOG episodes we think you’ll love:</p><p>Dr. Michael Greger – <a href="http://greatness.lnk.to/1583SC" target="_blank">greatness.lnk.to/1583SC</a></p><p>Dr. Will Bulsiewicz  – <a href="http://greatness.lnk.to/1621SC" target="_blank">greatness.lnk.to/1621SC</a></p><p>Glucose Goddess – <a href="http://greatness.lnk.to/1575SC" target="_blank">greatness.lnk.to/1575SC</a></p> <p></p><p>Get more from Lewis! </p><p><a href="https://lewishowes.com/money" target="_blank">Get my New York Times Bestselling book, <i>Make Money Easy</i>!</a></p><p><a href="https://open.spotify.com/show/1jWO57cwx0cXxHEwbfw85j?si=b570febb9a234e9f" target="_blank">Get The Greatness Mindset audiobook on Spotify</a></p><p><a href="https://greatness.lnk.to/chat" target="_blank">Text Lewis AI</a></p><p><a href="https://www.youtube.com/lewishowes" target="_blank">YouTube</a></p><p><a href="https://www.instagram.com/lewishowes/" target="_blank">Instagram</a></p><p><a href="http://lewishowes.com/" target="_blank">Website</a></p><p><a href="https://www.tiktok.com/@lewis" target="_blank">Tiktok</a></p><p><a href="https://www.facebook.com/lewishowes/" target="_blank">Facebook</a></p><p><a href="https://twitter.com/LewisHowes" target="_blank">X</a></p>
