Host Roy Bejarano welcomes Dr. David Katz, a globally recognized expert in preventive medicine, nutrition science, and public health. Dr. Katz shares his journey from traditional medicine to becoming a pioneer in lifestyle medicine, advocating for diet-based disease prevention and healthcare innovations that prioritize nutrition, exercise, and behavioral change over reactive treatments.

The conversation covers healthcare industry insights on the obesity epidemic, processed foods, nutrition policy, healthcare leadership, and the economic sustainability of healthcare. They discuss the intersection of healthcare policy, intelligence policy, and public health, and how food industry regulation, AI in healthcare, and national security threats impact healthcare trends in the U.S.

• [00:00] Introduction to the podcast and guest, Dr. David Katz
• [02:00] How a cardiologist’s son became a global leader in preventive medicine and nutrition science
• [06:30] The obesity epidemic: How the U.S. food industry manipulates diet and public health
• [18:00] The science of food addiction and the role of ultra-processed foods in chronic disease
• [30:00] Public health vs. healthcare policy: Why the U.S. system focuses on disease care instead of prevention
• [45:00] The role of government and regulation in curbing the influence of Big Food and Big Tobacco
• [55:00] AI, medical innovation, and the future of healthcare leadership in preventing chronic disease
• [1:10:00] Addressing misinformation in healthcare: How distrust, AI, and media distort public health efforts
• [1:30:00] The biggest healthcare challenge of the future: Preventing disease through better knowledge, not just better medicine

• Healthcare needs to shift from disease care to prevention. Dr. Katz explains how the U.S. healthcare industry profits from treating chronic disease rather than preventing it. Nutrition, exercise, and behavioral health should be primary, not secondary, concerns in healthcare leadership.
• The food industry profits from poor health. Ultra-processed foods are scientifically engineered to be addictive, leading to obesity, diabetes, and heart disease. Better regulation and public health education are critical to reversing this trend.
• AI & technology could revolutionize healthcare – or make it worse. AI-driven healthcare innovations can personalize preventive care, but misinformation and commercial interests must be addressed to ensure true healthcare industry insights.
• Public health and national security are connected. The U.S. healthcare system is at risk of economic collapse due to rising chronic disease rates. Preventive healthcare isn’t just a medical issue—it’s a public health and intelligence policy issue.
