An earlier version of this episode incorrectly stated that each participant in the AdventHealth Translational Research Institute study consumed a 2000-calorie diet. In fact, study participants were given customized menus so that the calories matched each person’s energy expenditure. This episode has been updated to reflect this correction.

What’s really going on inside your gut, and why should you care? In this episode, host Cristina Quinn explores the inner workings of the gut microbiome with Trisha Pasricha, a gastroenterologist and instructor at Harvard Medical School.

Pasricha explains how the gut microbiome acts as a key player in our overall health and why fiber may be one of the most underrated tools in supporting it. She also offers insight into what science currently understands about gut function and what’s still being uncovered.

Want to be a better conversationalist, listener, and all-around great company? In this special episode, host Cristina Quinn talks with Pulitzer-Prize-winning journalist and author Charles Duhigg ("Supercommunicators" and "The Power of Habit") about the science of effective communication.

Duhigg breaks down why some conversations feel effortless while others leave us frustrated — and how simple skills like asking deeper questions, practicing active listening, and matching emotional tones can make a difference.

They discuss the concept of “neural entrainment” — how our brains sync up during great conversations — and why feeling understood is more important than agreeing.

You’ll walk away with three easy tips to practice right away, plus a new mindset that could transform how you connect with friends, colleagues, and even strangers.

If you're ready to take back control of your attention, here’s where to start. Host Cristina Quinn chats with Washington Post tech columnist Geoffrey Fowler about self-binding — creating intentional boundaries with your devices to reduce distractions and reclaim your focus.

Geoffrey shares his own experiments and practical strategies, such as reorganizing a home screen and resetting algorithms. They also grapple with why traditional time limits on apps often backfire and how something as simple as moving an app off your home screen can shift your relationship with your phone.

Many of us are caught in a loop of instant gratification, driven by the brain’s reward system. In this episode, host Cristina Quinn talks with psychiatrist and addiction expert Anna Lembke about how to break free from compulsive digital habits and reset our dopamine levels.

Anna explains how our brains become desensitized to pleasure over time, making us crave more and more stimulation. The good news? A 30-day “abstinence trial” can help reset our baseline and bring our dopamine levels back into balance. But quitting isn’t easy — temporary withdrawal symptoms like anxiety, irritability and boredom often surface before things improve.

Through her own experience overcoming an unexpected addiction, Anna shares strategies to resist temptation, set up barriers to consumption and replace addictive behaviors with more fulfilling activities.

Reclaiming our attention isn’t just about cutting back — it’s about learning to be present, engage with the world around us and rediscover what truly brings us joy.

Ever wonder why you can’t stop scrolling, even when you know you should? It probably comes down to dopamine, a key neurotransmitter that drives pleasure and motivation. In this episode, host Cristina Quinn talks to psychiatrist Anna Lembke, author of “Dopamine Nation,” about the neuroscience behind digital addiction.

Anna explains how our devices keep us hooked by triggering dopamine surges — and why, over time, this actually leaves us feeling worse. She breaks down the “plenty paradox,” the idea that having unlimited access to pleasure might be making us more anxious and less happy.

But the good news? We can reset our dopamine levels and regain control of our attention. This episode lays the groundwork for understanding the science behind our tech habits — so we can start making intentional changes.
