This episode, I discuss grief and the challenges of processing losses of different kinds. I explain the biological mechanisms of grief, including how neural circuits for emotional and factual memory combine with those for love and attachmen...

My guest is Dr. Wendy Suzuki, Ph.D., Professor of Neural Science and Psychology and soon-to-be Dean of New York University, whose research focuses on memory, attention, brain plasticity and simple daily habits that can be leveraged to impro...

This episode I explain the mechanisms by which different types of memories are established in our brain and how to leverage the amount and timing of key neurochemicals and hormones, such as adrenaline (aka epinephrine) and cortisol, to impr...

This episode I describe the neural mechanisms that activate and control aggressive states and behaviors and the role of hormones—estrogen and testosterone—in mediating violent and/or competitive aggression. I also describe tools that can be...

My guest is Rhonda Patrick, Ph.D. She earned her doctoral degree in biomedical science from St. Jude Children’s Research Hospital at the University of Tennessee Health Science Center and has become one of the leading public health educators...

I describe the mechanisms by which deliberate heat exposure impacts body temperature, metabolism, heart health, hormone production, exercise recovery, cognition, mood, and longevity. I detail specific protocols for deliberate heat exposure,...

I describe the mechanisms by which different wavelengths of light impact the cells, tissues and organs of the human body, and how specifically timed light exposure of specific wavelengths can be used to improve sleep, enhance alertness, mod...

My guest is Dr. Kyle Gillett, MD, a dual board-certified physician in family medicine and obesity medicine and an expert in optimizing hormone levels to improve overall health and well-being in both men and women. We discuss how to improve...

I describe mechanisms by which deliberate cold exposure can enhance mental health, physical health, and performance. I detail specific protocols to safely engage in deliberate cold exposure, including minimal exposure times, time-of-day eff...

My guest is Dr. Andy Galpin, Professor of Kinesiology at California State University, Fullerton and one of the foremost experts in the world on the science and application of methods to increase strength, hypertrophy and endurance performan...

I explain how to blunt sugar cravings through fundamental knowledge of how sugar is sensed, metabolized, and utilized within the body. I explain how sugar is processed through the digestive tract and nervous system and how both the taste an...

I discuss the role of salt (sodium) in the nervous system and the key role that it plays in mental performance, physical performance and health. I explain how the brain senses salt levels in our body and how that relates to our feelings of...

My guest this episode is Dr. Justin Sonnenburg, Professor of Microbiology and Immunology at Stanford University. Dr. Sonnenburg’s research focuses on how microbes in our gut impact our mental and physical health and how diet and environment...

In this episode, I discuss the profound effect the gut has on the nervous system. I cover the structure and function of the gut-brain axis and the role of the gut microbiome in the brain and overall health. I describe how the gut controls h...

My guest is Dr. David Spiegel, MD, Associate Chair of Psychiatry & Behavioral Sciences, Director of the Center on Stress and Health and Director of the Center for Integrative Medicine at Stanford University School of Medicine. Dr. Spiegel h...
