20 lessons I only learned after becoming a Gastroenterologist & Hepatologist: 👇

1. The microbiome you have at 40 is not the one you were born with. You built it. You can rebuild it. 2. Fiber is the most underrated medicine in existence. 3. Most people eat less than half the fiber their body needs. Every single day. 4. Colonoscopy age dropped from 50 to 45 because colon cancer is rising in young people. That’s not a coincidence. That’s diet. 5. Fatty liver has no symptoms until it’s serious. Get your labs. 6. The gut talks to the liver. The liver talks to the brain. It’s one system. 7. Your microbiome needs diversity. Eating the same 10 foods is slowly starving it. 8. Leaky gut is real. It just has a better name in medical literature: increased intestinal permeability. 9. Butyrate is one of the most powerful compounds for gut health. Your bacteria make it. From fiber. That you eat. 10. Blood sugar stability is a gut health issue, not just a diabetes issue. 11. The vagus nerve connects your gut to your brain directly. Stress lives in your gut. 12. You can reverse early fatty liver completely. Most people don’t know that. 13. I’ve scoped thousands of colons. The healthiest ones belong to people who eat the most fiber. 14. Fermented foods aren’t a trend. They’re what humans ate for thousands of years. 15. The liver can fully reverse early-stage fat accumulation. It is one of the only organs that can regenerate. Give it the chance. 16. 800 million people globally have Type 2 diabetes. It is largely a fiber gap problem wearing a different name. 17. I had pre-diabetes and early fatty liver — as a gastroenterologist. The gap between knowing and doing is real. 18. I lost 30 pounds not through extremes — but by closing my own fiber gap. 19. Small, consistent changes beat dramatic cleanses. Every time. 20. The body isn’t working against you. It’s sending signals. Learn to read them. — Dr. Sethi Comment “CHEAT” and I’ll send you the fiber cheat sheet I share with my patients in clinic. #GutHealth #FiberGap #GutBrainAxis #FattyLiver #doctorsofinstagram
