Happy holidays from the RRP mothership.

Another year in the rearview. Time for what's become one of my favorite traditions, our annual “Best Of.” 12 years running now.

This year was packed with an astonishing array of guests—too many to feature here.

Part 1 revisits the year's most powerful moments: longevity science, neuroplasticity, happiness research, emotional regulation, consciousness, and what it actually takes to change.

I'm filled with gratitude for our guests, my team, and most of all—for you. I don't take your attention and support for granted. Here's to growing together in 2026.

Kevin Hall, Ph.D., is a physicist-turned-nutrition scientist whose rigorous research has upended some of our most sacrosanct beliefs about metabolism, dieting, and weight loss.

This conversation explores why diets fail, the truth behind the "slow metabolism" myth, how ultra-processed foods hijack our biology, and why the 800-pound gorilla driving the obesity epidemic isn't willpower—it's our toxic food environment.

He also opens up about his decision to leave the NIH after 20 years due to political interference with his research.

Kevin is an honest actor, always trying to set matters to rights amidst a hurricane of nutritional misinformation. Enjoy!

Rutger Bregman is a Dutch historian, bestselling author, and the guy who went viral telling Davos billionaires to pay their taxes.

This conversation is a salve for the crisis of meaning percolating through modern life. We explore Rutger's pragmatic antidote—moral ambition—and discuss why a quarter of workers believe their jobs are socially useless, what the abolitionists teach us about coalition-building, and why factory farming may be the ethical abomination future historians judge us for most harshly.

Rutger's conviction is rare and infectious. By the end of our conversation, I was so inspired that I committed $25K to his organization’s new US Food System Reform Program, a cause area that is deeply important to me.

Final Note: Through December 31st, every dollar to moralambition.org/food is matched.  I hope you’ll consider joining me today in making a donation to this impactful organization. See the links in our newsletter, on our website, and in our Substack. Let’s lean into our own moral ambition and do something truly meaningful, together.

Gregg Renfrew is the founder of Beautycounter and now Counter—a pioneer in the clean beauty movement.

Five years after our first exchange, Gregg returns with her story about navigating imposed change. After losing her company, she bought it back out of foreclosure in 48 hours—then let it die to save it. Today, we explore identity collapse, decoupling self-worth from success, why selling control means losing it, and the beauty industry's toxin loopholes.

Along the way, we confront rebuilding when everything you've created is stripped away.

This is an honest conversation about ego, humility, and the courage to begin again. Enjoy!

Roll On returns! Just in time for the holiday gauntlet.

Adam Skolnick and I unpack three questions the season demands: how to navigate family gatherings when the same dynamics play out like clockwork, what rock bottom actually means (hint: it's a launchpad for transformation, not a life sentence), and why I've traded rigid goals for something more like trajectory.

We get into the superpower of extreme neutrality, why everyone is right from their perspective, and morning pages as the unlock you didn't know you needed. We also celebrate Adam's debut novel “American Tiger”—finally out in the world!

Last but not least, we crown our favorite films of 2025. Enjoy!

Todd Marinovich is a former NFL quarterback, USC Rose Bowl champion, and the subject of the ESPN 30 for 30 documentary "The Marinovich Project."

This conversation explores the duality of engineered perfection and performance-based love. We discuss his father's authoritarian methods, the identity crisis of living someone else's dream, his harrowing addiction, the moment his father's approval paradoxically ended his motivation, and his journey toward self-compassion through art and recovery.

Through it all, Todd elucidates what it means to reclaim your humanity after decades of self-defiance.

Todd's story is raw and achingly human. And his message is clear—hope is a decision. Enjoy!

Oliver Burkeman is a bestselling author, journalist, and the mind behind “Four Thousand Weeks: Time Management for Mortals” and “Meditations for Mortals.”

We explore our broken relationship with time and Oliver's philosophy of imperfectionism, which dismantles the delusion that productivity is a moral imperative. Oliver explains why we're all chasing an infinite backlog, how perfectionism keeps us from doing the work, the path from overwhelm to agency, why acceptance isn't resignation, and the mystical energy of completion.

Along the way, Oliver diagnoses my biggest malfunction and exposes an uncomfortable truth about my people-pleasing tendencies.

Oliver's work is vital. And this conversation might just change your life. Enjoy!

This Fasting Compilation features Dr. Alan Goldhamer, Dr. Valter Longo, and Dr. Michael Greger to discuss the science of strategic deprivation.

We explore why visceral fat behaves like a tumor secreting inflammatory molecules that drive chronic disease. How many health conditions stem from dietary patterns rather than requiring medication alone. The evolutionary mechanism of insulin resistance and the reality that when you eat can matter as much as what you eat, with the same calories producing opposite metabolic outcomes depending on meal timing.

I also share my own challenges. Knowing the science doesn't make implementation easy.

Listen. Learn. And discuss with your healthcare provider what makes sense for you. Enjoy!

CRITICAL SAFETY NOTE: Under no circumstances should anyone undertake a water fast of any length without medical supervision. Do not attempt this at home.

Katie Couric is a journalist and the first woman to solo-anchor a major network evening newscast. 

We explore the disintermediation of news media, institutional distrust, and the fragmentation of shared truth in America. Katie shares her experiences navigating the CBS boys club, her perspective on the Sarah Palin interview, the craft of asking great questions, her cancer advocacy work after personal tragedy, and what she's learned about happiness. 

Along the way, Katie admits she's never been addicted to anything—until now. 

With four decades of perspective, Katie doesn't hold back. Enjoy!
