Michael Klaper, MD Is Educating The Next Generation of Doctors

Dr. Will Bulsiewicz is a gastroenterologist, one of the world's foremost authorities on the gut microbiome, and author of “Plant Powered Plus.” This conversation explores the gut-immune connection as the root determinant of chronic inflammation—the silent driver behind three out of five deaths. We discuss the four nutritional workhorses, why your microbiome is nocturnal, and what happens when you eat after dark. Dr. B also opens up about a decade-long estrangement from his father—an unexpected reminder that healing isn't always biological. Sometimes it's emotional. This is our third exchange together. Our best yet. Enjoy!

Mark Manson is the author of The Subtle Art of Not Giving a F*ck and host of the Solved podcast. Back for his third appearance (eps. 476, 882), we skip the backstory and pull questions from a fishbowl. We discuss vanity goals versus values-aligned goals, why procrastination is really about emotional avoidance, the trap of people-pleasing, how to distinguish intuition from impulse, and the delusion of passive manifestation. I also share my own shifting perspectives on positive thinking and the dissolution of self. Mark is the anti-guru. And this conversation is your New Year intervention. Enjoy!

The finale is here. Let's close this thing out. Part 2 explores courage, honesty, creativity, relationships, and balance. Bravery. Addiction. Love. Mastery.

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 and author of "Food Intelligence: The Science of How Food Both Nourishes and Harms Us. "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.

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.
