In this episode, I discuss Methyl​enedioxy​methamphetamine (MDMA), which is also commonly known as “ecstasy” or “molly,” including how it works in the brain to cause short- and long- term-shifts in emotional processing and its clinical applications for the treatment of post-traumatic stress disorder (PTSD), alcohol and other substance-use addictions. I discuss the neuronal mechanisms for how MDMA elevates mood, empathy, motivation, social engagement, and reduces “threat detection” and how these effects can synergistically support talk therapy. I also explain the ongoing debate about the potential neurotoxicity of MDMA, myths about the origins and treatments for post-MDMA “crash,” the evolving legal landscape around MDMA use for clinical purposes, and I caution recreational users about the extremely dangerous additives (e.g., fentanyl) now commonly found in black market MDMA. This should be of interest to those curious about MDMA, neuropharmacology, the origins of emotional processing in the brain, empathy, PTSD, neuroplasticity, mental health and psychiatry.

In this episode, I explain how medications such as Adderall, Ritalin, Vyvanse and other stimulants work to increase focus and treat attention-deficit/hyperactivity disorder (ADHD). I explain the brain circuits involved in focus and the key roles dopamine and norepinephrine play in their regulation. Then I explain how stimulants such as Adderall and Vyvanse can increase focus and reduce hyperactivity in kids or adults with ADHD, and how and why Ritalin and other medications (e.g., Modafinil, Guanfacine) may work better for some. I explain the long-term effects of ADHD medications on height, cardiovascular health, hormones, predisposition to addiction and psychosis, and whether these treatments can be used and then stopped. I also discuss the immense individual variation in dosage sensitivity for these medications and the negative side-effects that occur from recreational use. This episode ought to benefit anyone with ADHD, their parents, those on ADHD medications or anyone curious about how these medications work. For the full show notes, visit hubermanlab.com.

In this episode, my guest is Robin Carhart-Harris, PhD, distinguished professor of neurology and psychiatry at the University of California, San Francisco. He is one of leading researchers in the study of how psychedelics such as psilocybin, LSD and DMT can change the human brain and in doing so, be used to successfully treat various mental health challenges such as major depression, anorexia, obsessive-compulsive disorder (OCD) and addiction. He explains how psilocybin induces sustained changes in adaptive brain wiring and cognition. We discuss the key components of safe and effective psychedelic journeys, the role of hallucinations, the use of eye-masks to encourage people to “go internal,” and music, as well as what effective therapist support consists of before, during and after the session (also known as integration). We discuss micodosing vs. macrodosing and how researchers control for placebo effects in psychedelic research. We also discuss the current legal landscape around psychedelic therapies. Psychedelic therapies are fast emerging as powerful and soon-to-be mainstream treatments for medical health disorders, but they are not without their risks. As such, this episode ought to be of use to anyone interested in brain plasticity, mental health, psychology or neuroscience. For the full show notes, visit hubermanlab.com.

In this episode, I discuss what psilocybin is (chemically) and how it works at the cellular and neural circuit level to trigger neuroplasticity, which is our brain’s ability to rewire itself in ways that lead to long-lasting shifts in our emotional, cognitive and behavioral patterns and abilities. I discuss the emerging clinical trial evidence for the use of psilocybin in the treatment of depression, addictions and other psychiatric challenges. I explain the typical duration and phases of a psilocybin journey, the different categories of dosages often used and I explain the importance of set, setting and support when using psychedelics. I explain which groups of people place themselves at great risk by taking psilocybin as well as groups that could benefit, and I highlight the rapidly changing legal and medical landscape around psilocybin. This episode is a thorough exploration of psilocybin from the scientific and clinical literature perspective and ought to be of interest to anyone curious about psilocybin, mental health, neuroplasticity and/or psychedelics more generally.

In this episode, my guest is Noam Sobel, PhD, professor of neurobiology in the department of brain sciences at the Weizmann Institute of Science. Dr. Sobel explains his lab’s research on the biological mechanisms of smell (“olfaction”) and how sensing odorants and chemicals in our environment impacts human behavior, cognition, social connections, and hormones. He explains how smell is a crucial component of “social sensing” and how we use olfaction when meeting new people to determine things about their physiology and psychology, and he explains how this impacts friendships and romantic partners. He explains how smell influences emotions, hormone levels, memories and the relationship between breathing and autonomic homeostasis. He describes how smell-based screening tests can aid disease diagnosis and explains his lab’s work on digitization of smell — which may soon allow online communication to include “sending of odors” via the internet. Dr. Sobel’s work illustrates how sensitive human olfaction is and how it drives much of our biology and behavior. For the full show notes, visit hubermanlab.com.

In this episode, my guest is Matthew MacDougall, MD, the head neurosurgeon at Neuralink. Dr. MacDougall trained at the University of California, San Diego and Stanford University School of Medicine and is a world expert in brain stimulation, repair and augmentation. He explains Neuralink’s mission and projects to develop and use neural implant technologies and robotics to 1) restore normal movement to paralyzed patients and those with neurodegeneration-based movement disorders (e.g., Parkinson’s, Huntington’s Disease) and to repair malfunctions of deep brain circuitry (e.g., those involved in addiction). He also discusses Neuralink’s efforts to create novel brain-machine interfaces (BMI) that enhance human learning, cognition and communication as a means to accelerate human progress. Dr. MacDougall also explains other uses of bio-integrated machines in daily life; for instance, he implanted himself with a radio chip into his hand that allows him to open specific doors, collect and store data and communicate with machines and other objects in unique ways. Listeners will learn about brain health and function through the lens of neurosurgery, neurotechnology, clinical medicine and Neuralink’s bold and unique mission. Anyone interested in how the brain works and can be made to work better ought to derive value from this discussion. For the full show notes, visit hubermanlab.com.

In this episode, I explain the biology of hair, hair growth, why hair growth slows and what causes hair to stop growing and/or “fall out.” I discuss the essential role of hair stem cells and other supporting biological factors for healthy hair growth. Then I describe various approaches (mechanical and chemical) to slow hair loss by increasing blood flow to hair stem cells, including minoxidil, tadalafil, PRP, microneedling, Botox and ketoconazole treatments. I also discuss how age-related hormone changes cause hair loss and explain the effectiveness of treatments such as caffeine, saw palmetto, growth hormone, finasteride and dutasteride. For all hair growth options, I describe potential side effects, how soon to expect results and the amount of hair regrowth to expect and I highlight effective combination treatments for hair regrowth even in hair “dead” (bald) zones. For many listeners, thinning, brittle hair, or pattern baldness are a source of anxiety and stress.

In this episode, my guest is Elissa Epel, Ph.D., professor and vice chair of the department of psychiatry at the University of California San Francisco (UCSF) and the author of a new book entitled "The Stress Prescription." We discuss her work showing how stress impacts mood, eating behavior, mental health, physical health, and aging. She explains stress intervention tools using “top-down” techniques (e.g., radical acceptance, mindfulness, reframing), body-based methods (e.g., breathwork) including the Wim Hof Method, exercise, meditation, body scans, and environmental shifts proven to help people cease unhealthy rumination patterns. We discuss how stress can positively impact psychology and sense of purpose, how stress affects cellular aging, how our narratives of stressful events impact our mood and biology, and how to effectively reframe stress. She explains science-based techniques to break stress-induced cycles of craving and overeating and thereby improve insulin sensitivity and metabolic health. Dr. Epel provides a wide range of tools shown to be effective in reducing stress and improving various aspects of our health. For the full show notes, visit hubermanlab.com.

In this episode, I explain how dopamine dynamics — meaning changes and interactions between our baseline and peak levels of dopamine drive our cravings and sense of motivation. I also explain how to leverage dopamine dynamics to overcome procrastination. I cover behavioral, cognitive, nutrition-based and supplementation-based tools to optimize baseline and peak dopamine levels to ensure a persistently motivated state. I also discuss how to boost motivation when you are in a rut, why you might not want to stack behaviors/substances that spike dopamine and how to build and maintain a “growth mindset” for pursuing goals of any kind. Dopamine is an incredibly powerful neuromodulator involved in basic functions (e.g., hunger, romantic attraction, etc.) and feats of cognitive and physical performance; by understanding the dynamics of dopamine, listeners ought to be better positioned to overcome procrastination, maintain motivation, and improve confidence.

In this episode, my guest is Satchin Panda, PhD, professor and the director of the Regulatory Biology Laboratories at the Salk Institute for Biological Studies. We discuss his lab’s discovery that “time-restricted eating” (TRE) aka intermittent fasting, is beneficial effects for metabolic health and longevity. Dr. Panda explains how TRE, and also longer fasts, can positively impact obesity, diabetes, cardiovascular health, age-related chronic diseases, and improve mood and cognitive performance. He also describes how the timing of eating, light exposure and exercise that ~50% of all people engage in, negatively impacts their health and explains how specific simple adjustments to these can positively shift their subjective feelings of health and biomarkers of cardiovascular function, glucose regulation and metabolism. We discuss how our circadian behaviors, which include our patterns of eating, sleeping and socializing, have an enormous impact on our biology, mood and health and how by simply confining our calorie consumption to a semi-regular daily window, can positively impact our physical health, mental health and longevity.

In this episode, I discuss our body’s most vital and essential nutrient—water. I explain the structure of water and how it is used by the cells and tissues of our body, how much water we each need to drink and when in order to optimize our mental focus and physical performance; and I include how exercise, humidity, heat, and caffeine affect our hydration needs. I explain how temperature and pH influence water’s physical properties and if there is any scientific basis for drinking so-called “pH water” or “alkalized water” to improve health. I explain how to test your tap water for contaminants (e.g., endocrine disruptors) and the documented problems with fluoride in drinking water. I provide options for filtering drinking water and describe different water types (e.g., reverse osmosis, hydrogen-enriched, electrolyzed reduced, deuterium depleted, etc.). Since the human body is mostly water (55-80% depending on one’s age) and water has essential roles in health, disease and cellular function, everyone ought to benefit from understanding how best to clean our tap water, hydrate effectively and in some cases, adjust the type of water we drink to allow our brain and body to function optimally in regard to health and performance.

In this episode, my guest is Oded Rechavi, Ph.D., professor of neurobiology at Tel Aviv University and expert in how genes are inherited, how experiences shape genes and remarkably, how some memories of experiences can be passed via genes to offspring. We discuss his research challenging long-held tenets of genetic inheritance and the relevance of those findings to understanding key biological and psychological processes including metabolism, stress and trauma. He describes the history of the scientific exploration of the “heritability of acquired traits” and how epigenetics and RNA biology can account for some of the passage of certain experience-based memories. He discusses the importance of model organisms in scientific research and describes his work on how stressors and memories can be passed through small RNA molecules to multiple generations of offspring in ways that meaningfully affect their behavior. Nature vs. nurture is a commonly debated theme; Dr. Rechavi’s work represents a fundamental shift in our understanding of that debate, as well as genetic inheritance, brain function and evolution.

In this episode, I explain the biology of breathing (respiration), how it delivers oxygen and carbon dioxide to the cells and tissues of the body and how is best to breathe—nose versus mouth, fast versus slow, deliberately versus reflexively, etc., depending on your health and performance needs. I discuss the positive benefits of breathing properly for mood, to reduce psychological and physiological stress, to halt sleep apnea, and improve facial aesthetics and immune system function. I also compare what is known about the effects and effectiveness of different breathing techniques, including physiological sighs, box breathing and cyclic hyperventilation, “Wim Hof Method,” Prānāyāma yogic breathing and more. I also describe how to breath to optimize learning, memory and reaction time and I explain breathing at high altitudes, why “overbreathing” is bad, and how to breathe specifically to relieve cramps and hiccups. Breathwork practices are zero-cost and require minimal time yet provide a unique and powerful avenue to improve overall quality of life that is grounded in clear physiology. Anyone interesting in improving their mental and physical health or performance in any endeavor ought to benefit from the information and tools in this episode.

She discusses tools to enhance your quality of sleep, increase deep sleep, rapid eye movement sleep and growth hormone release-- a key hormone for health, immune function and vitality. Dr. Poe explains how a specific brain area, the locus coeruleus, facilitates the processing of emotions, helps relieve traumas and how to maximize locus coeruleus function. She also explains sleep’s vital role in opiate addiction recovery and how anyone can determine their optimal sleep timing and duration. This episode is rich with basic science information and zero-cost tools to enhance quality and effectiveness of sleep for sake of mental health, physical health and performance.

This is episode 3 of a 6-part special series on fitness, exercise and performance with Andy Galpin, PhD, professor of kinesiology at California State University, Fullerton. He explains protocols to improve the various kinds of physical endurance: muscular endurance, anerobic capacity, maximum aerobic output, and long duration endurance. He also explains how the body uses different energy sources (carbohydrates, proteins, fats) during rest and exercise. He also explains the mechanisms underlying fat loss and how and why exercise accelerates rates of fat loss. We cover the many concepts related to endurance training and fat loss such as metabolic flexibility, breathwork training for exercise performance and recovery, lactate production and regulation, how to improve blood flow to muscles, anaerobic vs. aerobic metabolism, exercise fatigue, low-carbohydrate diets and fat loss, and how to combine different types of workouts to improve overall endurance. This episode in intended for everyone ranging from novice and recreational exercisers to elite endurance athletes. Anyone wishing to improve their physical health and performance stands to benefit from the information. For the full show notes, visit hubermanlab.com.

I discuss the mechanisms by which human eggs and sperm are generated, the ovulatory/menstrual cycle, the conception process and overall fertility in males and females. I also explain how, regardless of whether you seek to conceive children, optimizing egg and sperm health is directly related to vitality and longevity. I cover nutritional, behavioral, supplemental, and medicinal approaches to optimizing egg and sperm health, the ovulatory/menstrual cycle and fertility. In addition, I explain lifestyle choices that greatly assist or harm fertility—several of which are very surprising. I provide science-based protocols for those trying to conceive children. The tools and principles I discuss can also improve overall vitality and longevity for everyone, regardless of age.  Thank you to our sponsors AG1 (Athletic Greens): https://athleticgreens.com/huberman LMNT: https://drinklmnt.com/huberman Waking Up: https://www.wakingup.com/huberman Momentous: https://www.livemomentous.com/huberman Timestamps (00:00:00) Fertility, Vitality & Longevity (00:04:24) Sponsors: LMNT (00:08:20) Eggs & Sperm, Genes, Fertilization (00:18:28) Puberty: Gonadotropin Releasing Hormone (GnRH), Melatonin & Leptin (00:23:38) Onset Trends of Puberty, Odors Effects (00:27:44) Female Puberty, Luteinizing Hormone (LH), Follicle Stimulating Hormone (FSH) (00:31:46) Sponsor: AG1 (00:36:34) Ovulatory & Menstrual Cycle (00:40:36) Follicular Phase: Egg Maturation & Ovulation, FSH & Estrogen (00:51:09) Luteal Phase: Progesterone & Estrogen, Menstruation (00:58:14) Ovulation & Libido; Luteal Phase & Malaise; Individual Variability (01:04:18) Sex Chromosomes, Sperm (01:11:40) Tool: Testicular Temperature & Fertility (01:17:22) Sperm Production, Seminal Fluid, Vasectomy (01:24:07) Sperm Cells, Mitochondria & Motility, Intercourse Frequency & Fertilization (01:28:31) Sperm Production, GnRH, FSH, LH & Testosterone (01:36:21) Ejaculate Quality, Sperm Counts, Fertilization, Ectopic Pregnancy (01:44:14) Tool: Sexual Intercourse Frequency & Fertilization (01:53:24) Tools: Tracking Ovulation, Libido, Lubricants (01:56:42) Fecundability: Egg Quality & Woman’s Age, Cumulative Pregnancy Rate (02:08:17) Miscarriages, Chromosomal Abnormalities (02:11:23) Female Fertility: Age, Follicle Testing & Anti-Mullerian Hormone (AMH) Testing (02:18:51) Male Fertility: Sperm Analysis, Age (02:24:52) Fertility & Hormone Analysis, Age (02:29:07) Fertility Effects of Sleep, Cortisol/Stress, Cannabis/Nicotine & Alcohol (02:42:40) Fertility, Sexually Transmitted Infections (STIs), Viral Infection & Cystic Fibrosis (02:47:42) Tool: Testicular Temperature & Fertility (02:51:26) Tool: Phones & Sperm Quality (02:58:06) Deliberate Cold Exposure & Fertility, Testicular Temperature, Cortisol/Stress (03:05:43) Fertility, Exercise & Mitochondrial Health; Intermittent Fasting (03:14:46) Testosterone Replacement Therapy & Sperm Production; Supplements (03:20:36) Sex Determination in Offspring, In Vitro Fertilization (IVF), Sperm Fractions (03:32:23) Postcoital Female Position & Fertilization, Sperm Quality (03:36:57) Cannabis & Sperm Motility, Libido, Pregnancy (03:42:33) Acupuncture, Fertility & Pregnancy (03:49:25) Fertility Supplements: L-Carnitine & Allicin, Coenzyme Q10 (03:56:18) Fertility Supplements: Inositol, Omega 3 Fatty Acids (04:02:50) Supplements for Hormones: Tongkat Ali, Shilajit, Zinc (04:13:02) Fertility & Prescription Medications (04:16:44) Human Reproduction & Fertility (04:20:12) Zero-Cost Support, YouTube Feedback, Spotify & Apple Reviews, Sponsors, Momentous, Social Media, Newsletter

In this episode, I explain how to design a supplementation protocol to support maximum mental and physical health and performance depending on your specific needs, nutrition, lifestyle and finances. When most people hear about “supplements,” they think they are vitamin supplements, but there are many compounds that are powerful and sold over-the-counter that can enhance our health in performance and that can’t be obtained from foods. First, I discuss “foundational” supplements to support overall health, including water and fat-soluble vitamins, minerals, digestive enzymes, adaptogens, and prebiotics/probiotics. Then I explain how to use single-ingredient supplements to enhance specific aspects of your physiology, such as aiding sleep, cognitive enhancement, and focus supporting healthy hormone levels (e.g., testosterone, estrogen and growth hormone, thyroid). Finally, I explain when it makes sense to add supplements to your lifestyle and discuss how best to use supplements, including how to determine dosage, sourcing, continuous schedules and cycling, and how to layer different supplements most effectively. This episode will explain how to design the safest, most biologically effective, cost-effective supplementation protocol to meet your particular goals and support your overall health, including vitality and longevity.

My guest is Sam Harris, Ph.D. Sam earned his bachelor’s degree in philosophy from Stanford University and his doctorate (Ph.D.) in neuroscience from the University of California, Los Angeles (UCLA). He is the author of multiple best-selling books and is a world-renowned public-facing intellectual on meditation, consciousness, free will, psychedelics and neuroscience. He is also the creator of Waking Up and the host of the "Making Sense" podcast. In this episode, we discuss meditation as a route to understanding “the self” and experiencing consciousness, not just changing one’s conscious state. Sam describes several meditation techniques and their benefits, including how meditation fundamentally changes our worldview and how it can be merged seamlessly into daily life. It can help us overcome universal challenges such as distractibility and persistent, internal dialogue (“chatter”) to allow for deep contentment and pervasive shifts in our awareness, all while acknowledging the more immediate stress-lowering and memory-improving effects of meditation. We also discuss the therapeutic use of psychedelics and the mechanistic similarities between the benefits of a psychedelic journey and long-term meditation practices. And we discuss the rationale behind Sam’s recent decision to close his social media (Twitter) account. This episode should interest anyone wanting to learn more about the higher order functions of the brain, the brain-body connection, consciousness and, of course, meditation and why and how to meditate for maximum benefit.

My guest is Jocko Willink, a retired Navy SEAL officer and author of multiple books on effective leadership and teamwork, self-discipline and mindset, and host of the Jocko Podcast. We discuss how people can build and sculpt their identity and psychology through specific mindsets and actions and how to adapt the self to novel and challenging situations, using specific daily routines. We consider how “energy” actually stems from physical action and describe practical tools and scientific mechanisms for leveraging exercise, cold exposure, nutrition, fasting, hydration, sunlight, mindset and music to make us feel more energized and what that, in turn, does for our life. Jocko explains how discipline and specific daily routines allow for productivity and creativity. And we discuss the qualities of successful leaders, including how to build confidence and real bonds when working with a team or family/friends. Jocko describes a particularly powerful tool of using perspective shifts to allow for ‘detachment’ as a unique way to identify novel solutions to problems. We also discuss the power of early developmental narratives and how experiences of friendship, love, connection and loss can serve as pillars for making us better human beings in all aspects of life. Our conversation covers a wide range of topics, including mental health, physical health and performance, and provides actionable tools that anyone, regardless of age or profession, can apply to live a more effective and meaningful life.

In this episode, I explain how the brain engages in creative thinking and, based on that mechanistic understanding, the tools to improve one’s ability to think creatively and innovate in any area. I discuss how convergent and divergent thinking are essential for generating creative ideas and provide three types of meditation tools (open monitoring meditation, focused attention meditation & non-sleep deep rest; NSDR), which improve our ability to engage in these creative thinking patterns in specific and powerful ways. I also discuss how dopamine and mood contribute to the creative process and describe behavioral, nutritional and supplementation-based approaches for increasing dopamine to engage in creative thought and implementation. I explain how movement and storytelling (narrative) approaches can generate novel creative ideas and how substances like alcohol, cannabis, and psilocybin impact our creative ability. Excitingly, creativity is a skill that can be cultivated and enhanced; this episode outlines many tools to help anyone access creativity and apply creative patterns of thought to different domains of life.

My guest is 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. We discuss how to optimize male hormones using a range of nutritional and behavioral tools, exercise, and supplementation (including discussions on tongkat ali, fadogia agrestis, creatine, peptides and more). We explain how puberty and aging affect hormone levels, how to use bloodwork to monitor hormone levels, how hormone health impacts fertility, libido, hair loss, and prostate health, and describe behaviors that negatively impact testosterone levels. We also discuss how to approach prescription hormone therapies, including which biomarkers to monitor when using these approaches and how to optimize synergistic hormones (e.g., growth hormone and thyroid hormone) to support complete hormone health safely and rationally. Dr. Gillett offers numerous actionable tools that can be tailored to specific goals and age ranges to attain and maintain optimal levels of male hormones for overall health, well-being and longevity.  For the full show notes, visit hubermanlab.com.

Welcome to a preview of the second Ask Me Anything (AMA) episode, part of the Huberman Lab Premium subscription. The Huberman Lab Premium subscription was launched for two main reasons. First, it was launched in order to raise support for the standard Huberman Lab podcast channel — which will continue to come out every Monday at zero-cost. Second, it was launched as a means to raise funds for important scientific research. A significant portion of proceeds from the Huberman Lab Premium subscription will fund human research (not animal models) selected by Dr. Huberman, with a dollar-for-dollar match from the Tiny Foundation.

In this episode, I explain how to use caffeine to enhance mental and physical health and performance, including the optimal dosages and intake schedules for caffeine. I explain how caffeine powerfully reinforces the consumption of certain foods and drinks—thereby increasing how much we like their tastes and seek them out. I discuss the mechanisms by which caffeine increases focus, alertness and mood and reduces sleepiness. I also explain many practical tools for caffeine use, including delaying caffeine intake after waking, intermittent caffeine use, during fasting, before and during exercise, and the use of theanine to curb jitters caused by caffeine. I also discuss the positive effects of caffeine on overall health and longevity and address several myths about caffeine. Since caffeine is one of the most commonly used substances (more than 90% of adults use caffeine daily!), this episode provides actionable tips for adjusting caffeine consumption to positively impact performance and health, including sleep.

My guest this episode is Chris Palmer, M.D., a board-certified psychiatrist and assistant professor of psychiatry at Harvard Medical School. He explains the important connection between nutrition, metabolism and mental health and his pioneering work using the ketogenic diet to successfully treat patients with various mental illnesses, including depression and schizophrenia. Dr. Palmer explains how the ketogenic diet is an evidenced-based treatment for epilepsy, mimics the fasted state and can offset the cognitive decline in Alzheimer’s. He describes the key roles of mitochondria in mental health, how certain conditions likely arise from mitochondrial dysfunction, and how low-carbohydrate diets increase mitochondrial turnover to improve mental health. He also explains how low-carbohydrate diets positively impact the gut microbiome and weight loss, important risk factors for mitochondrial health such as marijuana and alcohol, and the best way to increase circulating ketones depending on individual needs. We also cover how a ketogenic diet impacts mood, sleep, and fertility. Dr. Palmer’s work stands as a revolutionary approach to mental health and disease that, given the prevalence of mental health challenges, should be of interest to people of all backgrounds and ages.

I explain the science of happiness, including the different types of happiness and how our actions, circumstances and mindset control them. While it is difficult to standardize happiness from one person to the next, I outline a structured framework of what is critical to increasing your innate “natural happiness,” including financial security, purposeful work and relationships, and I explain specific tools to increase internal happiness (so-called “synthetic happiness”). I review how specific types of human connection and attention to our choices (or lack thereof) can increase or undermine our level of happiness. I also discuss the importance of certain types of physical contact, gratitude, financial choices and volunteer contributions that research shows can maximize happiness. And I discuss how factors such as children, pets, physical well-being, substance use, prior traumas and life-phase milestones affect our quest for and depth of happiness.

My guest is Layne Norton, Ph.D. — one of the world’s foremost experts in nutrition, protein metabolism, muscle gain and fat loss. We discuss the science of energy utilization and balance, the efficacy of different diets (e.g., ketogenic, vegan, vegetarian, carnivore, omnivore), and how best to build lean muscle mass and lose fat. We also discuss optimal protein and fiber intake, the best sources of protein, the correlation between appetite, satiety signals and exercise, along with male and female-specific needs. Dr. Norton also explains how to support a healthy gut microbiome and offers insight into sugar and artificial sweeteners, processed, cooked, and raw foods, supplements, seed oils, and the relationship of LDL/HDL levels to cardiovascular health. This episode serves as a master class in nutrition, metabolism and exercise and is sure to benefit people of all ages and with different health and fitness goals.

Welcome to a preview of the first Ask Me Anything (AMA) episode, part of Huberman Lab Premium subscription. The Huberman Lab Premium subscription was launched for two main reasons. First, it was launched in order to raise support for the standard Huberman Lab podcast channel — which will continue to come out every Monday at zero-cost. Second, it was launched as a means to raise funds for important scientific research. A significant portion of proceeds from the Huberman Lab Premium subscription will fund human research (not animal models) selected by Dr. Huberman, with a dollar-for-dollar match from the Tiny Foundation.

In this episode, I discuss the biological mechanisms of the state changes that occur during different types of meditation and describe how to develop the meditation practice optimal for you. I explain key meditation principles, such as using specific breathwork patterns and adjusting your perception to specific locations along the continuum between interoception, exteroception and dissociation. I discuss how meditation practices lead to long-term trait changes and neuroplasticity, including changing your default mood, reducing baseline anxiety/depression, increasing your ability to focus, enhancing relaxation, improving sleep, and increasing your overall happiness level. I also explain the concept behind the “third-eye center,” what mindfulness is from a biological standpoint, the power of ultra-brief meditations and how to select the best meditation and time and duration to meditate to meet your need. I also explain a novel open-eyed perception-based meditation that may enhance focus, relaxation and task-switching ability. Whether you are a novice or an experienced meditator or simply interested in how our brain controls different aspects of conscious awareness and self-regulation, this episode should interest you.
