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.
