In this episode, I discuss the importance of oral health for dental and microbiome health and general physical and mental well-being. I explain science-supported protocols for strengthening your teeth and gums, including how to remineralize your teeth. I cover the best approaches and timing for brushing and flossing, tongue, gum, and oral microbiome care and how oral health is critically important to offset metabolic, cardiac, and brain diseases, including dementia. I also discuss proper nutrition for oral health, fluoride, and how sugar and mouth breathing can accelerate tooth decay. This episode ought to be of interest to everyone seeking to improve their physical health, mental health, and lifespan, given the critical role that oral health plays in all of these.

In this episode, my guest is Dr. Kay Tye, Ph.D., Professor of Systems Neurobiology at the Salk Institute for Biological Studies and a Howard Hughes Medical Institute (HHMI) Investigator. We discuss the neural circuit basis of social interactions and loneliness. We also discuss how animals and people establish themselves in a group hierarchy by rank and how the brain responds to dominance and subordination. Much of our discussion relates to how social media impacts our sense of social connectedness or lack thereof. The topics covered in this episode are directly relevant to anyone interested in the neuroscience of mental health, work-life balance, abundance versus scarcity mindset, and interpersonal dynamics.

In this episode, I discuss working memory, which is critical for learning and productivity, strategy setting, goal seeking, and navigating new environments. I explain the key role of dopamine and the biological mechanisms underlying working memory and how working memory differs from both short- and long-term memory. I also describe science-supported tools to enhance working memory and attention—including zero- or low-cost behavioral, supplemental and pharmacologic approaches. I include how to assess your working memory and how to use memory tasks to determine your baseline dopamine levels in certain brain circuits. This episode provides listeners with highly actionable tools to assess and improve their attention to specific tasks and task-switching capacity and to enhance their overall productivity.

In this journal club episode, my guest is Dr. Peter Attia, M.D., a Stanford and Johns Hopkins-trained physician focusing on healthspan and lifespan and the host of The Drive podcast. We each present a peer-reviewed scientific paper chosen because it contains novel, interesting, and actionable data. First, we discuss a paper on how bright light exposure at sunrise and throughout the day and dark exposure at night independently improve mental health and can offset some of the major symptoms of mental health disorders such as depression and anxiety. Then, we discuss an article that explores a novel class of immunotherapy treatments to combat cancer. We also discuss some of the new data on low-calorie sweeteners and if they are safe. This episode should be of interest to listeners curious about maximizing their vitality and longevity and to anyone seeking science-supported ways to improve mental health and lifespan.

In this episode, I explain the biology of the common cold and flu (influenza) and how the immune system combats these infections. I describe behavior, nutrition and supplementation-based tools supported by peer-reviewed research to enhance immune system function and better combat colds and flu. I also dispel common myths about how the cold and flu are transmitted and when you and those around you are contagious. I explain if common preventatives and treatments such as vitamin C, zinc, vitamin D and echinacea work. I also highlight other compounds known to reduce contracting and duration of colds and flu.  I discuss how to use exercise and sauna to bolster the immune response. This episode will help listeners understand how to reduce the chances of catching a cold or flu and help people recover more quickly from and prevent the spread of colds and flu. Correction: I misspoke in the episode. A micron is 1/10,000 of a centimeter, not 1,000. Additionally, 1 millimeter equals 1/10 of a centimeter, not 1/100.

In this episode, my guest is David Goggins, retired Navy SEAL, highly accomplished ultramarathoner, best-selling author, and influential public speaker. David explains how he mastered his inner dialogue to build extraordinary levels of discipline and mental and physical toughness. He describes how confronting his early hardships, including physical and mental abuse, learning disorders, and obesity, became a practice of deep and excruciating self-reflection — eventually allowing him to transmute those experiences into a superhuman work ethic. This conversation is a unique window into David Goggins’ process in that it focuses both on the underlying science and how David manages and directs his inner dialogue. It’s a conversation that will inform and inspire anyone wondering how exactly to go about building discipline and confidence and reach their potential. Note: This conversation includes profanity. Some content might not be suitable for all audiences and ages.
