In this episode, John interviews gastroenterologist and nutritionist Dr. Sulaiman Bharwani (&quot;Dr. Sal&quot;) of Gut Rewire to unpack how the gut microbiome drives everything from heart health and brain function to anxiety, ADHD symptoms, and long-term disease risk - and exactly how to fix leaky gut naturally through food, sleep timing, breathing, and fasting.</p><p>Dr. Sal breaks down his &quot;7 Pillars&quot; framework (A–G: Avoid ultra-processed food, Breathe diaphragmatically, Count colors and plants, Drink water, early sleep, Fasting, and Go with movement), explains why the body can&#39;t actually digest fiber (the microbiome does that work for us), and makes the case that 30 different plants a week matters more than counting macros. </p><p>The conversation also covers the surprising, research-backed link between ADHD and gut symptoms, what really happens to the microbiome during a course of antibiotics, the current (and future) state of fecal transplants, and why the hours between 10 PM and 2 AM may matter more for gut repair than how many total hours of sleep you get.</p><p><strong>Key Topics:</strong></p><ul><li><li>Why the gut microbiome is now considered the body&#39;s most influential organ system, and its role in heart, brain, and immune health.</li></li><li><li>The real reason fiber matters (hint: it&#39;s not for you, it&#39;s for your bacteria).</li></li><li><li>Why &quot;eat more vegetables&quot; isn&#39;t useful advice anymore, and what 30 plants a week actually looks like.</li></li><li><li>What antibiotics do to your microbiome, and how to proactively protect it.</li></li><li><li>The gut-brain axis: how microbiome health shapes anxiety, sleep, focus, and decision-making.</li></li><li><li>A surprising research link between ADHD and GI symptoms in kids and adults..        </li></li><li><li>What leaky gut actually is, how it develops, and its downstream effects on inflammation, heart disease, and cognitive decline.</li></li><li><li>Fecal microbiota transplants: where the science stands today, and the open questions that still worry Dr. Sal.</li></li><li><li>The physiology of intermittent fasting, why 12–14 hours is the evidence-backed sweet spot, and why fasting may help your body clear out damaged cells.</li></li><li><li>Dr. Sal&#39;s &quot;7 Pillars&quot; (A–G) framework for rebuilding gut health.</li></li><li>
