What does your gut have to do with how well your brain performs? More than you might think. And if your stomach acts up before a big meeting, your gut may be responding to the same stress that is affecting your brain!Kiran Krishnan, research microbiologist with over 20 years of experience in health and nutrition, has conducted more than 50 human clinical trials on digestive health and the microbiome. He co-founded Microbiome Labs and now co-founds five other health and wellness companies, and has published in peer-reviewed journals and written chapters for global medical textbooks.In this episode, we explore the gut-brain axis and why the relationship between your gut and brain goes both ways. Kiran explains what stress can do to digestion, why chronic stress can contribute to leaky gut, and how poor sleep, stress, diet and other lifestyle factors can affect the health of your gut microbiome. We also unpack the five practical pillars he recommends for improving gut health, including fiber, polyphenols, stress management, sleep, exposure and supplementation, with simple strategies that can actually fit into a busy professional life.Timestamp00:00 Intro02:41 Why brain performance depends on gut health05:12 How the gut repairs the brain during sleep08:02 The gut brain axis as a two way superhighway11:39 How stress physically disrupts digestion16:45 Stress, inflammation and leaky gut19:10 What exactly is leaky gut?30:32 Common signs and symptoms of leaky gut34:20 Why you can assume you have leaky gut36:28 The habits that make leaky gut worse38:43 The five pillars for improving gut health1:00:25 How to get deeper into Kiran's workWhat We CoverWhy the brain needs a healthy gut to repair itself overnightHow the gut brain axis works as a two-way communication highwayWhy stress can trigger bloating, constipation, diarrhoea and other digestive symptomsWhat leaky gut actually meansWhy leaky gut is linked to anxiety, depression, joint pain, and blood sugar issuesThe everyday habits that quietly worsen leaky gut, from alcohol to poor sleepThe five pillars of gut healthWhy fiber and polyphenols are the most powerful tools for gut repairHow movement, even in small bursts, lowers stress and supports the gutWhy sleep quality matters more than sleep quantity for gut and brain repairThe gut-brain connection and cognitive performancePractical strategies for high performers who do not have time for a complete lifestyle overhaulKey TakeawaysYour gut and brain are in constant communication. What happens in one can influence the other.Stress physically damages your gut. Chronic stress is a major driver of leaky gut and the inflammation that follows.Leaky gut has a real name. Metabolic endotoxemia is the clinical term, and it is linked to conditions far beyond digestion.Stress does not stay in your head. It can directly affect how your digestive system functions.You don't need to overhaul your life. Small, consistent changes to diet, movement, stress and sleep can make a meaningful difference.Fiber and polyphenols matter. They help support the bacteria and compounds involved in maintaining the gut barrier.You cannot supplement your way out of poor lifestyle habits. Supplements come last, after the foundations are in place.Guest ResourcesLearn more about Kiran Krishnan: https://www.sivcare.comConnect With Me🌍 Website: https://charlenegisele.com📸 Instagram: https://instagram.com/charlenegisele💼 LinkedIn: https://www.linkedin.com/in/charlène-gisèle-bourliout/✉️ Subscribe to my Life Less Burnt Out Newsletter: https://charlenegisele.com/newsletter/
