Gut health is about much more than what you eat. In this episode, Dr Karan Rajan speaks with Kaitlin Colucci about the gut-brain connection, IBS, bloating, stress, sleep, meal timing, yoga, and the nervous system.

	Why Nothing Feels Fun Anymore: Dopamine, Phones & Brain Rot	04 May 2026	00:53:59
Your phone is not just distracting you, it may be changing what your brain finds rewarding. In this episode of Dr Karan Explores, Dr Karan Rajan speaks with neuroscientist TJ Power, founder of DOSE Lab, about dopamine, phone addiction, AI, “brain rot,” digital anhedonia, and why modern technology can make ordinary life feel less pleasurable. TJ’s DOSE framework focuses on dopamine, oxytocin, serotonin, and endorphins, the four brain chemicals he says are being disrupted by the way modern humans live. This conversation explores why so many of us feel stuck in loops of scrolling, distraction, apathy, and low motivation, and what it takes to reset our relationship with stimulation without pretending technology is “bad.” TJ shares why he believes 72 hours without screens can feel transformative, why boredom is harder than it sounds, and why becoming a “professional unplugger” may be one of the most important skills for the next generation. In this episode, we cover: What dopamine actually does beyond the online “dopamine detox” clichés Why phones, short-form content, sugar, alcohol, and AI can hijack reward pathways “Digital anhedonia”: Why normal life can start to feel dull or boring The 72-hour unplugged experiment and what happens by day two and day three Why boredom, stillness, walking, and doing nothing can restore creativity The default mode network and why your best ideas may need silence AI, “brain rot,” passive screen time, and outsourcing your thinking How to become a “professional unplugger” without quitting modern life 🎬 Chapters 01:13 – Why Modern Life Is Rewiring Our Brains 03:18 – What Dopamine Actually Does 06:06 – Phones, Short-Form Content & Dopamine Overload 09:28 – Why Nothing Feels Fun Anymore 12:27 – How to Break the Stimulation Loop 14:01 – 72 Hours Without Screens: What Happens to Your Brain 17:49 – Boredom, Creativity & the Default Mode Network 21:41 – Instant Gratification and the Collapse of Waiting 22:47 – AI, Brain Rot & Outsourcing Your Thinking 29:34 – Passive Screen Time vs Active Technology Use 32:37 – Are Some Brains More Dopamine-Hungry? 39:04 – Stillness, Silence & Rebuilding Attention 42:35 – AI Relationships, Oxytocin & Artificial Connection 46:10 – Why Technology Evolves Faster Than the Human Brain 48:27 – Dopamine and Why Time Feels Faster 52:03 – Becoming a Professional Unplugger 53:31 – Final Takeaway: Quiet Mornings, Coffee & No Phone 💩 Head to https://loamscience.com/products/loam-prebiotic-fiber-formula?utm_source=youtube&utm_medium=social&utm_campaign=drkaranexplores to try LOAM - and get an additional 10% with code POD10.💊 Get my free weekly newsletter filled with easy to action health tips, interesting facts and science to fill your curiosity: https://drkaran.beehiiv.com/subscribe🚽 Discover Throne's incredible new smart toilet device at http://thronescience.com📘 For more useful science for your everyday life, grab my best selling book "This Book May Save Your Life": https://geni.us/DrKaranBook📕 Get my new book, This Is Vital Information, here: https://linktr.ee/ThisisVitalInformation🤖 Discover my digital twin here: http://DrKaran.ai🧬 Sign up for my Microbiome Course waitlist: https://drkaran.kit.com/microbiome-course-waitlistAbout Dr Karan:Dr. Karan Rajan is a doctor, author, and educator dedicated to making health and medical science accessible to all.

	The Secret To Reducing Arthritis in 8 Weeks...	20 Apr 2026	00:53:12
Sleepwalking into arthritis isn’t inevitable. And some changes can show up faster than most people expect. In this episode, Dr Karan Rajan speaks with Professor Tamiko Katsumoto about why arthritis rates are rising, the differences between rheumatoid arthritis and osteoarthritis, and what the best evidence says about reducing joint inflammation, including a lifestyle medicine intervention where benefits were seen as early as 8 weeks (with the primary endpoint at 16 weeks). This isn’t about “miracle cures.” It’s about stacking the odds in your favour: Diet quality, fibre, fermented foods, weight and metabolic health, sleep, stress, movement. And how these interact with inflammation, the gut, and joint symptoms. In this episode, we cover: ∙ RA vs OA: Classic symptom patterns and why they’re treated differently ∙ Why treatments for osteoarthritis can feel limited (and why lifestyle is still worth discussing) ∙ “Food as medicine” and why joints are a symptom you can actually feel change ∙ The “Plants for Joints” study: What changed at 8 weeks and what the 16-week endpoint showed ∙ The gut-joint axis: Gut barrier, microbial diversity, and immune regulation ∙ Why some patients flare on ultra high meat / fibre-free approaches (and what to do instead) ∙ Practical “build my plate” guidance for joint and inflammation support #Arthritis #JointPain #RheumatoidArthritis #Osteoarthritis #Inflammation 💩 Head to https://loamscience.com/products/loam-prebiotic-fiber-formula?utm_source=youtube&utm_medium=social&utm_campaign=drkaranexplores to try LOAM - and get an additional 10% with code POD10. 💊 Get my free weekly newsletter filled with easy to action health tips, interesting facts and science to fill your curiosity: https://drkaran.beehiiv.com/subscribe 🚽 Discover Throne's incredible new smart toilet device at http://thronescience.com 📘 For more useful science for your everyday life, grab my best selling book "This Book May Save Your Life": https://geni.us/DrKaranBook 📕 Get my new book, This Is Vital Information, here: https://linktr.ee/ThisisVitalInformation 🤖 Discover my digital twin here: http://DrKaran.ai 🧬 Sign up for my Microbiome Course waitlist: https://drkaran.kit.com/microbiome-course-waitlist About Dr Karan: Dr. Karan Rajan is a doctor, author, and educator dedicated to making health and medical science accessible to all.

	The Best Sleep Schedule (According To Science)	09 Mar 2026	00:51:30
The best sleep schedule (according to science) isn’t just “8 hours”, it’s timing + consistency. In this episode, Dr Karan Rajan speaks with Professor Gina R.

In this conversation, we cover: Why sleep consistency is repeatedly linked with performance and healthier ageing outcomes A practical “best schedule” window (and why earlier sleep helps catch key deep-sleep biology) How light at night disrupts circadian timing (and why dim red light matters) Naps: when they help, and when they can backfire on night sleep Temperature and why overheating can reduce REM sleep Meal timing (“chrononutrition”) and why late meals can fragment sleep Plus: REM sleep, sleep spindles, memory, alcohol, and why some sedatives alter sleep architecture 🎬 Chapters 01:03 – Introducing Professor Gina R.

We track our steps, sleep, calories… even glucose. So why are we STILL getting sicker?
