Health at Its Origins: Food, Lifestyle, and Planetary Well-Being with David and Catherine Katz

Dr. David Katz takes us on a journey through the evolution of lifestyle medicine and its critical role in addressing our dual crises of chronic disease and environmental degradation. With characteristic wit and wisdom, he explains how our healthcare system has become primarily "disease care," waiting for patients to "fall off the wall" rather than preventing falls in the first place.Drawing on decades of experience in preventive medicine, Dr. Katz reveals the stark reality that diet quality has become the number one predictor of all-cause mortality in the United States. More sobering still is his assertion that 60% of COVID-19's impact in America was attributable to our population's poor metabolic health—a preventable tragedy had we addressed the "prior neglected pandemic" of lifestyle-related diseases.The conversation takes a delightful turn when Catherine Katz, neuroscientist and French foodie, joins to share how theory meets practice in their kitchen. Through her website Cuisinicity, she demonstrates that healthy eating need not be bland or restrictive. Her innovative approach transforms traditional recipes by maintaining the sensory experience while dramatically improving the nutritional profile—like her fiber-rich, protein-packed chocolate mousse that satisfies both the body and the most discerning palates.Together, the Katzes offer a masterclass in "taste bud rehab," explaining how our preferences can adapt to healthier foods in just weeks. They contrast this natural approach with ultra-processed foods engineered to maximize consumption before satiety signals activate. Their message is ultimately one of integration: we need both acute care for emergencies and systems that build "vitality at its origins," recognizing that the shifts in personal behavior that benefit human health also redound to the benefit of our planet.Ready to transform your relationship with food and health?
