What COVID has taught us about the benefits of a plant-predominant diet

The relationship between the microbiome, metabolic health, and weight management

How the microbiome affects cognition, brain health, and mental health

The adaptability of the microbiome

This week, I am joined by Tanya O’Callaghan, a musician, speaker, and activist, to discuss her unconventional journey from Ireland to a globally touring rock musician dedicated to advocacy. She talks about her roots volunteering at an animal shelter, her unexpected rise through LA’s music scene after a chance encounter with Maynard Keenan of Tool, and her commitment to a plant-based lifestyle even while on tour playing alongside legendary acts like Whitesnake, Puscifer, Iron Maiden’s Bruce Dickinson, and Dee Snider. Tanya discusses touring, the evolving food landscape in Ireland, and her deeply personal projects—a touring documentary promoting plant-based diets, and an upcoming film highlighting how plant-based nutrition can support veteran health and well-being. She also emphasizes staying true to your passions, engaging in respectful dialogue, and using storytelling to drive positive change.

Plant-Based Bassist Tanya O'Callaghan On How Changing Your Plate Can Change The World

This week, I am joined by Jonathan Haidt, an NYU professor and best-selling author, to discuss the significant negative impact of technology and social media on young people’s mental health and well-being. This phenomenon was catalyzed between 2010 and 2015 when smartphones were introduced and platforms like Instagram and Snapchat rose in popularity. He explains the harmful effects of hyper-connectivity, including loneliness, depression, self-harm, and suicide, as well as the foundational harms of social deprivation, sleep deprivation, cognitive fragmentation, and addiction. We examine the gender differences surrounding the impact of technology on mental health. Jonathan highlights the addictive nature of social media platforms and the collective action problem that prevents individuals from disengaging. He proposes potential solutions, such as setting clear norms for smartphone and social media use, implementing phone-free school policies, and restoring childhood independence. We also discuss the need for regulation and bipartisan support to address the toxic effects of social media on children's mental health.

Jonathan Haidt On How Social Media Is Rewiring Childhood

This week, I am joined by Scott Galloway, NYU professor, best-selling author, serial entrepreneur, and podcaster, to discuss the multifaceted challenges many young men face today. He underscores the lack of empathy and understanding many experience, attributing it to societal expectations and the impact of technology. Scott emphasizes the winner-take-most economy, which limits opportunities for many young men. Drawing from personal understanding, he stresses the importance of education, support, and the presence of positive male role models. The discussion encompasses economic challenges, the decline of mentorship programs, and the need for reform in higher education institutions. Addressing societal constructs of masculinity and the importance of vulnerability and integrity, Scott advocates embracing emotions and seeking help to navigate life’s hurdles. He stands apart as a model of healthy, grounded masculinity—one defined by humility, emotional intelligence, and a commitment to uplifting the collective rather than indulging narrow self-interest.

The Dean of Stanford Medical School on How AI Is Shaping The Future of Health Precision

This week, I’m joined by Michael O’Brien, a former executive, and father of two who experienced a profound transformation after a life-altering cycling accident. Previously consumed by 65-hour work weeks, his perspective shifted when an SUV collided with him head-on. While being airlifted to medical care, he vowed to relinquish his pursuit of happiness, propelling him toward personal growth. Michael shares his resilience journey post-accident, labeling the day of the incident as “My Last Bad Day.” He discusses the pivotal role of perception in confronting life’s adversities, narrating his 11-year journey towards forgiveness for the driver accountable, inspired by the power of forgiveness. Embracing uncertainty, he reflects on physical limitations, debunking the illusion of control. Michael advocates for mindfulness, emphasizing gradual habit formation and lifestyle development. Michael imparts universal lessons on resilience, self-discovery, and growth. Please enjoy!
