In this episode, my guest is Dr. Gabrielle Lyon, D.O., a board-certified physician who did her clinical and research training at Washington University in geriatrics and nutrition. She is also an expert in how diet and exercise impact muscle and whole-body health and longevity. Dr. Lyon is a bestselling author and public educator. We discuss how healthy skeletal muscle promotes longevity, brain health, disease prevention, ideal body composition, and the health of other organs and bodily systems. She makes specific nutritional recommendations for optimal health: what to eat, how much to eat, the timing of meals, the essential need for adequate quality protein (including animal and plant-based options), supplementation, and how our dietary requirements change with age. She explains why specific types of resistance training are essential to build and maintain muscle and overall metabolic health. She also describes how to include resistance training as part of your exercise regimen — regardless of age or sex.  She also provides specific mindset tools to encourage sustained adherence to healthy eating and exercise practices. Women and men of all ages will benefit from Dr. Lyon’s practical, evidence-based protocols to improve muscle and whole-body appearance, function, and health.

In this episode, my guest is Dr. Zachary Knight, Ph.D., a professor of physiology at the University of California, San Francisco (UCSF), and Howard Hughes Medical Institute (HHMI) investigator. We discuss how the brain controls our sense of hunger, satiety, and thirst. He explains how dopamine levels impact our cravings and eating behavior (amount, food choices, etc) and how we develop and can change our food preferences and adjust how much we need to eat to feel satisfied. We discuss factors that have led to the recent rise in obesity, such as interactions between our genes and the environment and the role of processed foods and food combinations. We also discuss the new class of medications developed for the treatment of obesity and diabetes, including the GLP-1 agonists semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro). We discuss how these medications work to promote weight loss, the source of their side effects, and the newer compounds soon to overcome some of those side effects, such as muscle loss. Dr. Knight provides an exceptionally clear explanation for our sense of hunger, thirst, and food cravings that translates to practical knowledge to help listeners better understand their relationship to food, food choices, and meal size to improve their diet and overall health.

In this episode, my guest is Dr. Jonathan Haidt, Ph.D., professor of social psychology at New York University and bestselling author on how technology and culture impact the psychology and health of kids, teens, and adults. We discuss the dramatic rise of suicide, depression, and anxiety as a result of replacing a play-based childhood with smartphones, social media, and video games. He explains how a screen-filled childhood leads to challenges in psychological development that negatively impact learning, resilience, identity, cooperation, and conflict resolution — all of which are crucial skills for future adult relationships and career success. We also discuss how phones and social media impact boys and girls differently and the underlying neurobiological mechanisms of how smartphones alter basic brain plasticity and function.  Dr. Haidt explains his four recommendations for healthier smartphone use in kids, and we discuss how to restore childhood independence and play in the current generation.  This is an important topic for everyone, young or old, parents and teachers, students and families, to be aware of in order to understand the potential mental health toll of smartphone use and to apply tools to foster skill-building and reestablish healthy norms for our kids.

In this episode, my guest is Dr. Diego Bohórquez, PhD, professor of medicine and neurobiology at Duke University and a pioneering researcher into how we use our ‘gut sense.’ He describes how your gut communicates to your brain and the rest of your body through hormones and neural connections to shape your thoughts, emotions, and behaviors. He explains how your gut senses a range of features such as temperature, pH, the macro- and micronutrients in our foods, and much more and signals that information to the brain to affect our food preferences, aversions, and cravings. Dr. Bohórquez describes his early life in the Amazon jungle and how exposure to traditional agriculture inspired his unique expertise combining nutrition, gastrointestinal physiology, and neuroscience. We discuss how the gut and brain integrate sensory cues, leading to our intuitive “gut sense” about food, people, and situations. This episode provides a scientific perspective into your gut sense to help you make better food choices and, indeed, to support better decision-making in all of life.
