In this episode, I host Dr. Samer Hattar, Ph.D., Chief of the Section on Light and Circadian Rhythms at the National Institute of Mental Health. Dr. Hattar is a world-renowned expert on how viewing light at particular times adjusts our mood, ability to learn, stress and hormone levels, appetite, and mental health. We discuss how to determine and use your individual light sensitivity to determine the optimal sleep-wake cycle for you. We also discuss how to combine your light viewing and waking time with the timing of your food intake and exercise in order to maximize mental and physical functioning. Dr. Hattar is credited with co-discovering the neurons in the eye that set our circadian clocks and regulate mood and appetite. He explains why even a small shift in daylight savings leads to outsized effects on our biking because of the way that our cells and circadian clocks integrate across many days. And he offers precise tools to rapidly adjust to jet lag, shift work, and reset your clock after a late night of work or socializing. This episode is filled with cutting-edge data on the biological mechanisms of human physiology and practical tools for people of all ages.  Read the full show notes for this episode at hubermanlab.com.

This episode I describe science-supported nutrients for brain and performance (cognition) and for nervous system health generally. I describe 10 tools for this purpose, including specific amounts and sources for Omega-3 fatty acids which make up the "structural fat" of neurons (nerve cells) and allow them to function across our lifespan. I also review data on creatine, phosphatidylserine, anthocyanins, choline, glutamine and how they each impact brain function in healthy people seeking to reinforce and improve their cognition and in those combatting cognitive decline. I describe both food-based and supplement-based sources for these compounds, and their effective dose ranges based on peer-reviewed literature. Then I review the 3 factors: gut-brain signaling, perceived taste, and learned associations that combine with the metabolic and blood-sugar-elevating effects of food to determine what foods we seek and prefer. Amazingly, it's not just about what tastes good to us. Next, I explore how we can leverage the neural circuits of learned food preference toward seeking and enjoying the right foods for brain health and performance. I also review new data on non-caloric sweeteners and why consuming them with glucose-elevating foods can be detrimental, in some cases rapidly leading to insulin dysregulation. This episode covers more than 10 actionable tools for those seeking to improve and/or maintain brain function, and it explains modern neuroscience underlying of our sense of taste, our food seeking preferences and brain metabolism.

This episode I discuss the science and practice of fasting also called time-restricted feeding. I review the data on how limiting food intake to specific portions of every 24-hour cycle (or fasting longer) impacts weight loss, fat loss specifically, liver health, mental focus, muscle, longevity and more. I explain how "fasted" is contextual, and relates to blood glucose levels and their downstream effects, and how the depth of fasting can be adjusted with behaviors such as different types of exercise, or with glucose disposal agents. I also discuss the optimal fasting protocol: and both the absolute (non-negotiable) and variable (contextual) features of a fasting/time-restricted-feeding protocol that will allow you to get the most benefits. I also discuss what does and does not break a fast, the effects of fasting on hormones like testosterone and cortisol and on fertility. I also review how different feeding windows of 8 or 10 or 4 hours differentially impact the effects of fasting, and why the classic 8 hour feeding window came to be but also might be ideal. I discuss mechanisms and offer tools to discern the optimal fasting duration and timing for you.  Read the full show notes for this episode at hubermanlab.com.
