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.

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.For the full show notes, visit hubermanlab.com.Thank you to our sponsorsAG1 (Athletic Greens): https://athleticgreens.com/hubermanLMNT: https://drinklmnt.com/hubermanSupplements from Momentoushttps://www.livemomentous.com/hubermanTimestamps(00:00:00) Food & Brain Function Introduction(00:02:08) Summary: Critical Aspects of Time Restricted Feeding/Fasting(00:04:36) Sponsors: AG1, LMNT(00:08:24) Neuroplasticity Super Protocol (Zero-Cost Tools) Online(00:09:22) Eating to Enhance Brain Function & Foundational Aspects of Brain Health (00:13:00) Eating Fats for Brain Health, EFAs Phospholipids (Tool 1: 1-3g EPA Omega-3/day) (00:20:35) Phosphatidylserine (Tool 2: 300mg/day)(00:22:15) Choline, Egg Yolks (Tool 3: 1-2g/day Threshold)(00:28:26) Hydration & Electrolytes (Tool 4)(00:29:50) Liquid Fish Oil/Capsules (2-3g EPA per day; 300mg Alpha GPC 2-4X/week)(00:32:22) Creatine for Cognition (Tool 5: 5g/day) (00:36:28) Anthocyanins, Dark Skin Berries (Tool 6-10mg/day (Extract), 1-2 cups Berries) (00:41:19) L-Glutamine (Tool: 1-10g/day) & Offsetting Apnea & Inflammation(00:49:23) Neural Basis of Food Preference, Yum, Yuck, Meh; Taste, Guts, & Beliefs(00:55:25) Taste is 100% In your Head(00:59:50) Gut Neurons Controlling Food Preference: Neuropod Cells; (Tool 7: Fermented Foods) (01:06:14) Capsule Probiotics, Brain Fog (01:07:16) Learning to Like Specific Tastes: Sweetness & Brain Metabolism(01:12:11) Hard-Wiring & Soft-Wiring(01:13:25) Artificial & Non-Caloric Sweeteners: Safe or Harmful Depends on (Glucose) Context(01:18:15) Non-Caloric Sweetener & Insulin; (Tool 8: Don’t Have w/Glucose Elevating Foods)(01:22:17) Beliefs & Thoughts; The Insula; (Tool 9: Pairing-Based Reshaping Food Preferences) (01:30:42) Liking Neuro-Healthy Foods & Bettering Brain Metabolism (Tool 10); Food Wars(01:36:05) Food Reward & Diabetes, Obesity; Important Review Article (See Caption)(01:38:28) Synthesis, Zero-Cost Support, Future Topic Suggestions, Sponsors, SupplementsTitle Card Photo Credit: Mike BlabacDisclaimer

In this episode, I host Dr. Samer Hattar, 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 jetlag, 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.

This episode discusses metabolism and how our thyroid hormone and growth hormone control our metabolism. I also clarify that metabolism isn't just about burning energy, it’s about converting energy from different sources into fuels for building and repairing our tissues such as muscle, brain, and tendons and mobilizing energy from body fat storage. I discuss the role of iodine, selenium, and salt for thyroid health, and how specific exercise protocols, amino acids and temperature can dramatically shift levels of growth hormone release in waking and in sleep. I also describe the current landscape of prescription compounds, peptides and other factors for changing levels of thyroid and growth hormone, and some of their risks. Throughout the episode, mechanisms and tools grounded in specific mechanisms are discussed.Supplements from Thornehttps://www.thorne.com/u/hubermanTimestamps(00:00:00) Introduction(00:06:05) Thyroid & Growth Hormone(00:08:44) Food Shapes: Do They Matter?(00:11:43) Stevia: Naming & Impact(00:13:30) Metabolism 101: Your Brain the Furnace(00:17:33) Releasing Hormones From Your Brain, Stimulating Hormones from Your Pituitary(00:21:04) Thyroid Hormone’s Real Effects: Growth, Repair and Energy Consumption of Tissues(00:22:45) Iodine, L-Tyrosine & Selenium: The Trio Essential For Thyroid Function(00:26:05) How Much Iodine Do We Need?

This episode I discuss the science and practice of learning physical skills: what it involves at a biological level, and what to focus on during skill learning at each stage to maximize learning speed and depth. I also describe what to do immediately after a training session (note: this is different than the optimal protocol for cognitive skill training) and as you progress to more advanced levels of performance. I also cover the science of skill-based visualization which does have benefits, but only if done correctly and at the correct times. I discuss auto-replay of skill learning in the brain during sleep and the value of adding in post-training ‘deliberately idle’ sessions. I cover how to immediately improve limb-range-of-motion by leveraging cerebellum function, error generation, optimal repetition numbers for learning and more. As always, scientific mechanism, peer-reviewed studies and science-based protocols are discussed.

In this episode, I discuss how hormones such as testosterone and estrogen and their derivatives impact the early development of the brain and body and their maturation. I review published data on environmental factors shown to powerfully alter hormone pathways in animals and humans and the effects of cannabis, alcohol and cell phones on testes, sperm, ovaries and hormones. I describe the predictable relationship between genes, beard growth and balding patterns, and the importance of estrogen for brain development in people of all chromosomal sexes. Finally, I discuss how the hormones we are exposed to in the womb shape the relative length of our finger digits, the sounds our ears make (yes you read that correctly), and how those correlate with people's self-reports of their sexual preferences.

In this episode, I discuss the biology of emotions and moods in the context of relationships. I focus on the science of how early infant-caregiver attachment, combined with adolescence and puberty shape our adult patterns of attachment. I explain the three universal aspects of emotions, the reality of right-brain versus left-brain personalities, and how the roots of adult attachment are also grounded in specific aspects of puberty. I review what factors determine when puberty starts and ends, and the role of oxytocin and other chemicals in controlling how we perceive and remember others. As always, I refer to various practical tools including new tools for understanding and predicting our emotions before they occur, and neurochemicals that shape human connection.

This episode explains the science of motivation and drive. I describe how dopamine-- a chemical we all make in our brain, underlies our desire for and pursuit of our goals, as well as our capacity to move and experience pleasure. I describe how we can leverage specific behaviors, reward schedules and dopamine-prolactin balance to help ensure we can maintain motivation and capacity for pleasure over the long term. I also discuss dopamine in the context of ADHD, craving and addiction, and some absolutely amazing results about specificity of drug effects based purely on belief.For the full show notes, visit hubermanlab.com.Thank you to our sponsorsAG1 (Athletic Greens): https://athleticgreens.com/hubermanLMNT: https://drinklmnt.com/hubermanWaking Up: https://www.wakingup.com/hubermanMomentous: https://www.livemomentous.com/hubermanTimestamps(00:00:00) Introduction(00:00:30) Sponsors: AG1, LMNT, Waking Up(00:04:22) Announcement: Spanish Subtitles(00:05:06) Emotions, Addiction & Mindset(00:06:22) Motivation & Movement: The Dopamine Connection(00:07:29) A Double-Edged Dopamine Blade(00:08:56) Dopamine Fundamentals: Precursor to Adrenalin(00:10:15) The Reward Pathway: An Accelerator & A Brake(00:12:10) Motivation= Pleasure Plus Pain(00:14:14) The Dopamine Staircase: Food, Sex, Nicotine, Cocaine, Amphetamine(00:16:15) Subjective Control of Dopamine Release(00:17:40) Social Media and Video Games(00:18:15) Addiction & Dopamine: Progressively Diminishing Returns(00:18:48) Novelty, Sensation-Seeking & Anticipation(00:20:15) Craving: Part Pain, Part Pleasure & Pain Always Prevails(00:23:11) Desire Scales With Pain: The Yearning Function(00:24:43) The Croissant Craving Circuit(00:25:45) “Here and Now” Molecules: Serotonin, Bliss & Raphe Nucleus(00:26:26) In Your Skin Or Out In the World(00:27:25) Cannabinoids Lethargy & Forgetfulness(00:28:15) The Almond Meditation(00:29:30) Drugs That Shift Exteroception Versus Interoception(00:30:36) Emotional Balance, Active & Passive Manipulation(00:32:36) Procrastination: Leveraging Stress, Breathing, Caffeine, L-Tyrosine, Prescription Drugs(00:37:04) When Enough Is Never Enough; How Dopamine Undermines Itself(00:38:58) Dopamine-Prolactin Dynamics: Sex, Reproduction & Refractory Periods(00:40:30) The Coolidge Effect: Novelty-Induced Suppression of Prolactin(00:42:22) Vitamin B6, Zinc As Mild Prolactin Inhibitors(00:43:25) Schizophrenia, Dopamine Hyperactivity and Side Effects of Anti-Dopaminergic Drugs(00:45:08) Prolactin, Post-Satisfaction “Lows” & Extending the Arc of Dopamine(00:48:00) The Chemistry of “I Won, But Now What?”(00:49:00) Healthy Emotional Development: Child and Parent(00:50:03) Never Say “Maybe” (Reward Prediction Error)(00:52:02) Surprise!(00:52:59) Are You Suppressing Your Drive and Motivation By Working Too Late?(00:54:50) Disambiguating Pleasure and Drive: Dopamine Makes Us Anti-Lazy(00:58:00) Beta-Phenylethylamine (PEA), & Acetyl L-Carnitine(01:00:00) Attention Deficit Disorders, Cal Newport Books, Impulsivity & Obesity(01:03:55) Leveraging Dopamine Schedules(01:05:22) Subjective Control of Dopamine and Drug Effects: The “Adderall” Experiment(01:09:03) Caffeine May Protect Dopamine Neurons, Methamphetamine Kills Them(01:10:57) Nicotine: Dopamine, Possible Neuroprotection, Prolactin Increase(01:11:53) Gambling, Intermittent Reinforcement, & Persistent Goal Seeking (Bad and Good)(01:14:14) Intermittent Halting of Celebration; Enjoy Your Wins, But Not All of Them(01:18:38) A Story Example of Intermittent Reward to Maintain Long-Term Drive and Motivation(01:21:25) Corrections & Notes About Spanish Captions & Other Languages Soon(01:24:00) Synthesis & Framework, Zero-Cost Support & A Note About SponsorsTitle Card Photo Credit: Mike BlabacDisclaimer

This episode explains the brain-body connections that allow the specific foods we eat to control our moods and motivation. I discuss the vagus nerve and its role in dopamine and serotonin release in the brain. I review Omega-3 fatty acids and the key role of the gut microbiome in supporting (or hindering) our mental and emotional states. Many actionable tools are reviewed and discussed related to fasting, ketogenic and plant-based diets, probiotics, fermented foods, fish oils, artificial sweeteners, specific supplements that promote dopamine and serotonin, and some remarkable behavioral (and belief) effects.For the full show notes, visit hubermanlab.com.Thank you to our sponsorsAG1 (Athletic Greens): https://athleticgreens.com/hubermanLMNT: https://drinklmnt.com/hubermanWaking Up: https://www.wakingup.com/hubermanMomentous: https://www.livemomentous.com/hubermanTimestamps(00:00:00) Introduction(00:00:31) Sponsors: AG1, LMNT, Waking Up(00:05:00) Emotions: Aligning Mind & Body(00:06:41) Nutrients, Neurochemicals and Mood(00:08:39) Primitive Expressions and Actions(00:12:30) The Vagus Nerve: Truth, Fiction, Function(00:15:45) “Vagus Stimulation”: A Terrible Concept(00:16:35) Polyvagal Theory(00:18:27) Vagus Senses Many Things, & Moves Our Organs(00:19:35) Sugar Sensing Without Perception of Sweetness(00:23:00) Eating-Induced Anxiety(00:27:30) We Eat Until Our Brain Perceives “Amino Acid Threshold”(00:29:45) Reward Prediction Error: Buildup, Letdown and Wanting More(00:32:01) L-Tyrosine, Dopamine, Motivation, Mood, & Movement(00:34:04) Supplementing L-Tyrosine, Drugs of Abuse, Wellbutrin(00:38:29) Serotonin: Gut, Brain, Satiety and Prozac(00:43:38) Eating to Promote Dopamine (Daytime) & Serotonin (Night Time)(00:44:30) Supplementing Serotonin: Sleep, & Caution About Sleep Disruptions(00:46:40) Examine.com An Amazing Cost-Free Resource with Links to Science Papers(00:48:05) Mucuna Pruriens: The Dopamine Bean with a Serotonin Outer Shell(00:51:00) Emotional Context and Book Recommendation: “How Emotions Are Made”(00:54:55) Exercise: Powerful Mood Enhancer, But Lacks Specificity(00:56:45) Omega-3: Omega-6 Ratios, Fish Oil and Alleviating Depression(01:01:00) Fish Oil as Antidepressant(01:02:40) EPAs May Improve Mood via Heart Rate Variability: Gut-Heart-Brain(01:07:24) Alternatives to Fish Oil to Obtain Sufficient Omega-3/EPAs(01:09:05) L-Carnitine for Mood, Sperm and Ovary Quality, Autism, Fibromyalgia, Migraine(01:16:29) Gut-Microbiome: Myths, Truths & the Tubes Within Us(01:21:55) Probiotics, Brain Fog, Autism, Fermentation(01:25:20) Artificial Sweeteners & the Gut Microbiome: NOT All Bad; It Depends!(01:28:00) Ketogenic, Vegan, & Processed Food Effects, Individual Differences(01:33:20) Fasting-Based Depletion of Our Microbiome(01:35:20) How Mindset Effects Our Responses to Foods: Amazing (Ghrelin) Effects!(01:38:30) How Mindset Controls Our Metabolism(01:41:03) Closing Comments, Thanks, Support & ResourcesTitle Card Photo Credit: Mike BlabacDisclaimer

This episode explains what stress is, and how it recruits our brain and body to react in specific ways. I describe the three main types of stress, and how two of them actually enhance the function of our immune system making us less vulnerable to infections. I review tools that allow us to control our stress in real-time, as well as tools to prevent long-term stress, burnout and stress-induced illness and anxiety. As always, we cover behavioral tools and supplements that can assist or hinder stress control.

In this episode, I describe how to access focused learning bouts, creative states, and the underlying neural circuitry involved. I frame this in the context of our daily 24-hour cycle in order to make it practical, clear and precise about timing. I review the role of fasting, meal timing and specific types of nutrients for promoting certain states of mind. I also review various other tools and biological factors that directly or indirectly gate brain function and that we can control. I answer commonly asked questions about the science of psychedelics, binaural beats, and visualization.

In this episode, I discuss how we can use specific types of behavior to change our brain, both for sake of learning the movements themselves and for allowing us to learn non-movement-based information as well. I describe the key role that errors play in triggering our brains to change and how the vestibular (balance) system can activate and amplify neuroplasticity. As always, I cover science and science-based practical tools. Thank you in advance for your questions and for your interest in science!

This episode introduces neuroplasticity—which is how our brain and nervous system learn and acquire new capabilities. I describe the differences between childhood and adult neuroplasticity, the chemicals involved and how anyone can increase their rate and depth of learning by leveraging the science of focus. I describe specific tools for increasing focus and learning. The next two episodes will cover the ideal protocols for specific types of learning and how to make learning new information more reflexive.

This episode is all about the two major kinds of dreams and the sorts of learning and unlearning they are used for. I discuss REM-associated dreams that control emotional learning and their similarity to various trauma treatments such as ketamine and EMDR. I also discuss Non-REM dreams and their role in motor learning and learning of detailed, non-emotionally-laden information. I relate this to science-backed tools for accessing more of the types of sleep and learning people may want. Other topics are listed in the time stamps below.

Today’s episode provides an introduction to how the nervous system works to create sensations, perceptions, emotions, thoughts and behaviors, as well as how we can change our nervous system—a phenomenon known as neuroplasticity. The information sets the stage for all Huberman Lab podcast episodes that follow by covering neurons, synapses, brain chemicals and the rhythms that control our ability to focus, learn and sleep… and more. Thank you for your interest in science. We'll see you next week!
