In this episode, Peter sits down with Drs. Marty Makary and Zubin Damania (aka ZDoggMD), both previous guests on The Drive. Marty is a Johns Hopkins professor and public health researcher and ZDoggMD is a UCSF/Stanford trained internist and the founder of Turntable Health. This episode, recorded on December 27, 2021, was in part inspired by some of the shoddy science and even worse messaging coming from top officials regarding COVID-19. In this discussion, Marty and ZDoggMD discuss what is known about the omicron variant, the risks and benefits of vaccines for all age groups, and the taboo subject of natural immunity and the protection it offers against infection and severe disease. Furthermore, they discuss at length the poor messaging coming from our public officials, the justification (and lack thereof) for certain mandates and policies in light of the current evidence, and the problems caused by the highly politicized and polarized nature of the subject. Themes throughout the conversation include the difference between science and advocacy, the messaging which is sowing mistrust in science despite major progress, and a search for what a possible “end” to this situation might look like.  NOTE: Since this episode was recorded over the holiday and published ASAP, this is an audio-only episode with limited show notes.  We discuss: Comparing omicron to delta and other variants [4:15]; Measuring immunity and protection from severe disease—circulating antibodies, B cells, and T cells [13:15]; Policy questions: what is the end game and how does the world go back to 2019?

In this episode, David discusses his framework for assessing the potential harm caused by common recreational drugs and explains how they are regulated, which is oftentimes misaligned with actual risk. He describes in detail the neurobiology, mechanisms of action, and addiction potential of alcohol, opiates, cocaine, and methamphetamine and contrasts those with psychedelics, which have been given a similar regulatory classification despite their relatively low risk of harm and their numerous potential therapeutic uses. Additionally, David explains the promise of psychedelics like ketamine, MDMA, and psilocybin for treating drug addiction and depression and discusses how political pressures have created roadblocks to future necessary research. We discuss: David’s early interest in the brain and experience in psychiatry [2:45]; David’s brief work on government drug policy in the UK [10:15]; A scale for rating the relative harm of certain drugs [13:45]; The contrast in regulation between cannabis vs. alcohol and why research on potential benefits of cannabis is lacking [19:15]; The opiate crisis and rise of fentanyl: the cause and potential solution [25:00]; The science of addiction and the potential use of psychedelics for treating drug addiction [35:00]; Cocaine: mechanisms of action and risks [41:45]; Methamphetamine and crystal meth: mechanisms of action and neurotoxicity [48:15]; How psychedelics came to be classified as schedule I drugs despite their numerous therapeutic uses [52:45]; The history of MDMA and the bad science and political forces leading to its demonization [1:08:45]; History of ketamine, medical use of esketamine, and the waning effects of psychedelics with increasing usage [1:13:30]; Psilocybin for depression: David’s promising research and the roadblocks to more robust experiments [1:20:15];More.

Robert (Bob) Gatenby is a radiologist who specializes in exploring theoretical and experimental models of evolutionary dynamics in cancer and cancer drug resistance. He has developed an adaptive therapy approach for treating cancer which has shown promise in improving survival times with less cumulative drug use. In this episode, Bob explains what brought him into medicine, his search for organizing principles from which to understand cancer, and the mathematical modeling of other complex systems that led him to model the dynamics of tumor cell changes in cancer. He discusses his pilot clinical trial treating metastatic prostate cancer, in which he used an evolutionary game theory model to analyze patient-specific tumor dynamics and determine the on/off cycling of treatment. He describes how altering chemotherapy to maximize the fitness ratio between drug-sensitive and drug-resistant cancer cells can increase patient survival and explains how treatment of metastatic cancer may be improved using adaptive therapy and strategic sequencing of different chemotherapy drugs.

Lawrence Wright is the author of The Looming Tower: Al-Qaeda and the Road to 9/11 which won the 2007 Pulitzer Prize for general nonfiction and was named one of Time's top 100 books of all time.  In this episode, released just before the 20th anniversary of the September 11th attacks, Lawrence and Peter discuss the book and the lasting impact of that day. Lawrence reflects on his personal experiences on that day and how he was first drawn into reporting on the attacks. Lawrence then discusses in detail the history that led up to 9/11 which is really composed of two parallel stories. The first story is of the growing discontent in Muslim countries, the roots of Islamic radicalism, and how two extremists, Osama bin Laden and Ayman al-Zawahiri, joined forces to create the global terrorist organization Al-Qaeda. The second story is about how interpersonal and institutional conflicts between the FBI and CIA led to a massive failure in intelligence and resulted in multiple missed opportunities to predict and prevent the attacks on September 11th, 2001.

In this episode, I sit down with my daughter to discuss the brutal death of George Floyd, and the aftermath we are watching unfold. Though I have no expertise in race relations, law enforcement, or police brutality, I do have some knowledge in the training of physicians, and it is that training of doctors that I’ve been thinking about lately as it may offer one small insight into this crisis. In this very short discussion, we speak about three types of errors in medicine (and medical training), how to distinguish between the two variants that are acceptable, and the one that is unacceptable. My question, ultimately, is if such a framework can be applied to law enforcement?   Learn more: https://peterattiamd.com/ Subscribe to receive exclusive subscriber-only content: https://peterattiamd.com/subscribe/ Sign up to receive Peter's email newsletter: https://peterattiamd.com/newsletter/ Connect with Peter on Facebook | Twitter | Instagram.

In this episode, Mark Hyman, M.D., director of the Cleveland Clinic Center for Functional Medicine and the author of Food Fix, discusses that if we can fix the food system, we can solve many big problems—namely the chronic disease/obesity epidemic, the rising costs of healthcare, as well as the big problems facing the environment. Mark first briefly lays out the health consequences of processed food with a focus on the gut microbiome. From there, Mark discusses the environmental consequences of industrial farming and lays out how we can affect change on the individual level, through policy and regulations, and perhaps most importantly through regenerative agriculture. Additionally, Mark talks about the potential health risks of consuming GMO foods, herbicides, and other chemicals used in industrial farming as well as the environmental consequences, such as the loss of soil, caused by those same fertilizers and methods of farming. We discuss: The negative consequences of the existing food environment [3:25]; What makes processed food so unhealthy? [9:00]; The gut microbiome: Inflammation from gut permeability and how to measure gut health [18:30]; Steps to fixing a bad gut—The Five R’s [24:30]; Some staggering health statistics, and which races might be more genetically susceptible [27:15]; An argument for government regulations and policies to fight back against a massive food industry with unlimited resources (and what we can learn from the tobacco story) [29:00]; Industrial farming and climate change: The degradation of soil and use of fertilizer [41:45]; Regenerative agriculture: Could it be the answer to food waste, our health problems, and the environment? [51:45]; Comparing the Impossible Burger to regeneratively raised beef [1:06:00]; GMO and Roundup—The potential health risks of consuming GMO foods sprayed with Roundup (glyphosate) and other herbicides and pesticides [1:08:15]; How the livelihood of farmers are being affected by big ag companies and the current industrial farming system [1:16:30]; The loss of biodiversity in our food, and what “organic” really means [1:19:00]; What can people do on the individual level to protect themselves as well as affect change to the toxic food system? [1:25:00]; What role does the USDA play in this “toxic” food environment and how do we fix it? [1:30:15]; The top 3 changes Mark would make if he was “food czar” [1:35:15]; Mark’s rebuttal against the argument that it’s best for the environment if we stop farming animals and move to a fully plant-based diet (and his argument for “agriculture 2.0") [1:36:30]; What is Mark’s overall mission with the work that he’s doing? [1:40:30]; Bread in the US vs. Europe: Why does bread (and wheat products) taste different and potentially cause less health problems in Europe versus the US? [1:42:00]; and More.

In this episode, Dr. Iñigo San Millán, Assistant Professor at the University of Colorado School of Medicine, explains the crucial role of mitochondrial function in everything from metabolic health to elite exercise performance.

In this episode, David Light, CEO of Valisure (the company which alerted the FDA to the Zantac cancer concerns), explains the story behind the recent recalls by manufacturers of ranitidine, a common heartburn medication, sold under the trade name Zantac, due to a potential link to increased cancer risk. David breaks down all the evidence, the role of his unique pharmacy company which tests all its drugs before being dispensed to consumers, and the reason behind the FDA’s tempered reaction to the alarming study results. David makes the argument that Zantac/ranitidine is an inherently unstable molecule which explains the grossly excessive amounts of NDMA (a probable human carcinogen) as opposed to just a contamination for which there could be numerous causes. Finally, David and Peter both provide recommendations for what to do if you or someone you know is currently taking Zantac/ranitidine. We discuss: The impetus for starting Valisure, a unique online pharmacy that tests all its medications [6:45]; The story behind the recall of valsartan, and the role which Valisure played [24:30]; Testing Zantac: The shocking results from Valisure’s initial testing with major potential cancer implications [36:00]; NDMA - the probable human carcinogen found in Zantac/ranitidine [48:45]; The epidemiology question: Are we inferring too much from epidemiology? What can we take away from the existing studies? [53:30]; The staggering results from the 2016 Stanford study, why it didn’t alarm more people, and how Valisure found the missing biological link [1:01:30]; Alerting the FDA, the FDA’s tempered response, and question of contamination vs. inherent instability [1:07:30]; How confident is David that the elevated levels of NDMA being found in ranitidine are not due to instrumentation, human error, or temperature contamination? [1:24:15]; The massive risk being taken by the FDA by not doing more to keep ranitidine away from consumers [1:25:15]; If someone is taking Zantac/ranitidine, what should they do? What else do they need to know? [1:27:45]; and More.

In this episode, Jason Fried, co-founder of Basecamp, shares his beliefs around achieving business success in a modern world which tends to disproportionately focus on the massive success stories (the outliers). Jason gives his honest take on companies like WeWork, Uber, and Lyft that may give off the appearance of wild success but may instead provide an example of the dangers of perverse incentives. We get into Jason’s backstory, and how his affinity for optimizing efficiency and production in the workplace culminated with the creation of Basecamp, his very successful web-based project management software business. Perhaps most importantly, we get really deep into all aspects of work-life balance and what it really means to “work hard” (Stay tuned for an AMA-style deep dive into the topic of work-life balance with Jason in the near future). In addition, Jason provides many more valuable nuggets including thoughts on some common mistakes made by businesses today, the value of giving employees autonomy, how to take the right types of risks, why he doesn’t set any goals, and much, much more. We discuss: Jason’s background and his early entrepreneurial spirit [9:45]; Views on completing higher education and the notion of hard work [24:00]; Beliefs around success in business [35:00]; WeWork, Uber, and Lyft: Poor business practices and the dangers of perverse incentives [41:30]; Jason’s early career: his redesign approach and personal motivation [56:00]; The genesis of Basecamp [1:10:00]; Why Jason does not set goals but instead focuses on a vision [1:12:15]; Workplace motivation and hiring practice [1:20:30]; The importance of luck and not overworking [1:32:00]; A framework to work less and optimize for workplace autonomy [1:38:00]; The importance of saying ‘no’ more often (and tips for doing so) [1:55:00]; A shared passion for watches [2:03:30]; Guarding against the perils of phone addiction [2:08:45]; Jason’s views on email and chat for communication [2:15:00] and; More.

In this episode, Katherine Eban, investigative journalist and author of Bottle of Lies, illuminates the prevalence of fraud in generic drug manufacturing which brings into question the idea that generics are identical to brand-name drug as we are lead to believe. Katherine walks us through how this widespread corruption came to be, including the shocking story of one particularly egregious (and unfortunately not uncommon) example of an Indian drug company, Ranbaxy, whose business model was completely dependent on falsifying data in their drug applications to the FDA. We then discuss the subsequent investigation into Indian and Chinese drug manufacturing plants which revealed that nearly 80% of them are tainted with fraud. We conclude this discussion on a positive note with i) how individuals can investigate their own drugs to protect themselves ii) an innovative pharmacy attempting to disrupt the market and iii) some ideas on how to reform to the regulations around generic drugs, the FDA, and more.   We discuss: How Peter found Katherine’s book, and what convinced her to investigate the generic drug industry [5:45]; Branded vs. generic drugs: Why they aren’t the same thing [11:15]; The Food and Drug Administration: Why it was originally created and what it does today [20:45]; How the generic drug industry really got its start in the U.S., and the flaw of the Hatch-Waxman Act [28:20]; PEPFAR: How a well-intentioned plan to help Africa with the AIDS epidemic laid the groundwork for corruption [36:30]; The story of Ranbaxy: An Indian drug company whose business model was fraud and deceit [40:45]; How the FDA approves drugs, the impact of “first to file”, and Peter’s tangent on moral corruption [47:30]; A booming generic drug market and the FDA struggling to keep up [57:15]; Dinesh’s internal investigation finds widespread fraud and falsified data inside Ranbaxy [1:00:15]; Presenting the famous SAR document to Ranbaxy’s board of directors which spells out the company-wide fraud [1:09:15]; Dinesh blows the whistle on Ranbaxy which leads to a raid on their US plant [1:19:45]; Formal investigation of Ranbaxy is launched, but the FDA keeps approving Ranbaxy drug applications [1:33:30]; What role does the culture in India play in the high prevalence of fraud in the drug industry? [1:41:00]; The extreme prevalence of data fraud/manipulation in foreign generic drug factories [1:52:30]; Concluding the Ranbaxy story [2:06:15]; How concerned should you be when buying a generic drug from your local pharmacy?

In this episode, David Sinclair, Ph.D., a Professor in the Department of Genetics at Harvard Medical School and co-Director of the Paul F. Glenn Center for the Biological Mechanisms of Aging, returns to the podcast to discuss the content of his new book, Lifespan: Why We Age - and Why We Don’t Have To. This conversation focuses on the biological mechanisms involved in what David terms the Information Theory of Aging which provides insights into the “clock” that determines our aging and to what degree it can be manipulated. Our discussion on aging of course leads us into interconnected topics of epigenetics, sirtuins, cellular senescence, as well as what compounds David is personally taking for his own longevity. Additionally, we discuss the most up to date information related to NAD and longevity by looking at the potential benefits (if any) of supplemental agents (NAD precursors, NR, NMR, etc.) that pose a promise of increasing NAD. We discuss: SIR genes and cellular identity [8:45]; Sirtuins regulate gene expression [14:30]; DNA is methylated at the deepest layer of the epigenome [17:45]; Methylation pattern and determining cellular age [20:15]; Cellular reprogramming [33:45]; Yamanaka factors to push cells "back in time”  [41:00]; Human cellular reprogramming viability [57:00]; Measuring the rate of aging [1:02:45]; Cellular reprogramming for longevity [1:14:45]; Compounds David takes for his own longevity [1:29:15] NAD precursors (NR, NMN) and pterostilbene [1:40:00]; The current field of sirtuin activators [2:03:15]; David’s artistic work [2:05:15] and; More.

In this episode, Rick Doblin, founder and executive director of MAPS, discusses MDMA, a molecule that has (at a minimum) revolutionary therapeutic benefits for PTSD, but arguably could have, at the highest order, a lasting impact on humanity’s ability to peacefully coexist. Rick details the history of MDMA, what lead to its unfortunate criminalization, and his lifelong work trying to protect MDMA (and other psychedelics) from criminalization (and his subsequent attempt to decriminalize it). Through his founding of MAPS, Rick has made enormous progress in debunking many of the exaggerated risks being claimed against MDMA (neurotoxicity, memory loss, depression, Parkinson’s, etc.), and is very close to getting FDA approval for a psychotherapy technique using MDMA. Additionally, in this discussion, you will learn about the history of LSD, psilocybin, and other psychedelics and how the combination of the misunderstanding of them with the crackdown on drug use in the 1970s lead to their designation of schedule 1 substances. But it’s important to note that you will also realize from this discussion just how different MDMA is compared to the average psychedelic. We end this discussion with a message of hope: there are going to be many people who are going to wonder what can they do to receive this MDMA therapy. We talk about what those clinical trials look like, what the enrollment looks like, and perhaps more importantly, what a compassionate use license would look like, such that if there are patients who are in need of this therapy (prior to its approval) they can have an understanding of the legal paths to doing just that. We discuss: Discovering MDMA, how Rick learned about it and his first experiences with it [9:45]; The timeline of MDMA’s evolution, the reinvention in the 1970s, “ecstasy”, the criminalization of MDMA [21:10]; Explaining the different “schedules” of drugs [30:55]; Rick’s fight to protect it for therapeutic uses, losing to the DEA despite winning in the court, the scientific community, and the media [38:25]; The risks involved with taking MDMA [42:30]; An incredible MDMA-LSD case study: Rick’s story of healing a treatment-resistant PTSD patient in the 1980s [44:45]; How and why MDMA was declared illegal on an emergency basis going against the judge’s recommendation after hearing Rick’s compelling case (and multiple appeals) in court [57:15]; Rick’s decision to study politics to affect change from the inside out, and the recent progress being made with the DEA [1:07:00]; Debunking the exaggerated risks of MDMA (e.g., neurotoxicity) [1:16:30]; Rick’s unbelievable ability to play the long game [1:28:45]; Which patients would not be good candidates for MDMA from a safety perspective? [1:34:30]; How MDMA is different from all other psychedelics, the importance of the setting, and Peter’s experiences with MDMA [1:36:30]; MDMA studies which lead to the crucial designation as a “breakthrough therapy” [1:40:30]; How someone with PTSD can get treated now through “expanded access for compassionate use” [1:46:00]; Rick’s ultimate goal and long term vision for psychedelic clinics [1:50:30]; Trip of Compassion documentary, and how psychedelics could change the world [1:52:30]; Rick’s early life: Resisting the draft, his feeling of wanting to change the world, and his profound experiences with LSD and other psychedelics [1:55:30]; The history of LSD and psilocybin, and the CIA’s interest in psychedelics [2:10:45]; Timothy Leary and the Good Friday Experiment [2:22:00]; Rick’s follow up study to the Good Friday Experiment, and his criticism (and praise) of Tim Leary [2:33:50]; Peter’s experience taking psilocybin [2:44:30]; The Concord Prison Experiment, and Rick’s follow up study 34 years later [2:47:00]; and More.

In this episode, board-certified plastic surgeon, Zol Kryger, enlightens us about the frighteningly loose laws regulating the industry of plastic surgery, paving the way for a majority of cosmetic procedures being performed by doctors that are not board-certified plastic surgeons. We talk about some of the very serious complications that can occur even in “minimally invasive” procedures, where the incidence rate is only increased by the flood of non-certified doctors who want to offer these procedures to augment their income. Fortunately, Zol provides listeners with a very specific list of important questions to ask a surgeon when considering any of the many cosmetic procedures available. We then go into the specifics of the most common procedures and the risk of complications for each of them, including breast augmentation, tummy tucks, liposuction, Brazilian butt lifts, botox and fillers, facial peels and lasers, and more. By the end of this episode, you'll have a really clear understanding of what these risks are and how you can go about reducing those risks by choosing the right physician. We discuss: Why Zol chose plastic surgery [7:30]; The shockingly high percentage of plastic surgery being done by non-board certified doctors, and the laws that allow it to happen [11:20]; 10 Questions to Ask Your Cosmetic Surgeon (PDF Download) [21:00]; Complications: Why you must ask your doctor about potential complications and how they would deal with them [24:20]; Zol’s first complication, how he dealt with it, and how having a partner to check your work is great for the doctor and patient [32:30]; Breast augmentation: What you need to know—types of implants, complication rates, and Zol’s summary of the safest and most effective way to do it [39:10]; Breast reconstruction following a mastectomy [1:06:30]; Tummy tuck: How it’s done, biggest risks involved, scarring, and how it can address hernias and diastasis [1:13:00]; Liposuction: How it works, the potential complications and risks involved, and the importance of choosing the right doctor in the “wild west” of liposuction [1:26:45]; Butt lifts: Rising popularity, major risks, the frighteningly loose laws regulating the industry, and how the butt lift industry is eerily similar to the subprime mortgage crisis [1:37:00]; What is it about plastic surgery (and not other segments of medicine) that compels (and allows for) untrained doctors to offer these procedures? [1:49:45]; Peter asks Zol if he ever feels emotionally conflicted working in an industry that sometimes can feed off the vanity and insecurity of people [1:56:25]; Does Zol ever turn down patients? [2:02:45]; The risks involved with botox, fillers, facial peels, and laser treatments [2:07:45]; and More.

In this episode, Keith Flaherty, director of clinical research and targeted cancer therapy at Massachusetts General Hospital, shares his vast wealth of knowledge in cancer starting with the history of treatment from chemotherapy to radiation to surgical therapy and where those methodologies seemed to have leveled off. He also walks us through the timeline of advancements (and lack there of) from when the War on Cancer was declared in the 1970s, through the sequencing of the entire human genome, and all the way to today. Keith dives into the topic of immunotherapy, probably the most exciting recent development in cancer therapy, and also provides us a rundown of his notion of a different approach to cancer that attacks all the essential pillars of cancer growth and survival. Finally, we talk a little bit about liquid biopsies, we discuss the roles of CRISPR and other potentially over-hyped therapies with respect to cancer.

In this episode, radiologist/engineer, Raj Attariwala, explains how he was able to apply his engineering background to create a unique MRI scanner that is capable of constructing whole-body images with a resolution that is unmatched in the industry. Peter and Raj discuss the implications of such a robust, radiation-free imaging tool on the early detection of cancer. They dive deep into cancer screening and define terms such as sensitivity and specificity that are necessary to really understand this complex space. They then describe the biggest risks involved in this type of screening (false positives) and how Raj’s unique technology and process might drive down this risk substantially. But before that, they discuss all the common imaging technology from X-ray, to CT scan, to PET scans, to ultrasound, to MRI, and more. They touch on the history of each, how they work, the usefulness and limitations of each of them, as well as the varying risks involved such as radiation exposure. If you are interested in cancer screening and/or you’ve ever wondered how any radiology tool works, this episode is for you. We discuss: Raj’s road from engineering to radiology [7:45]; How X-ray works, the risk of radiation exposure, and the varying amounts of radiation associated with the different imaging technologies [18:00]; Computed tomography scans (CT scans): The history of CT, how it works, and why we use contrast [27:45]; Ultrasound: Benefits and limitations, and a special use for the heart [40:45]; Detecting breast cancer with mammography: When is works, when you need more testing, and defining ‘sensitivity’ and ‘specificity’ [51:15]; Magnetic resonance imaging (MRI): How it works, defining terms, and looking at the most common types of MRI [1:03:45]; Brain aneurysms: Using MRI to find them and save lives [1:23:45]; Raj’s unique MRI technology [1:30:00]; The risk of false positives in cancer detection, and how Raj’s MRI can reduce the number of false positives (i.e., increase specificity) [1:43:40]; The unique software Raj created to pair with his MRI machine [1:51:15]; Comparing the radiation exposure of a whole-body PET-CT to Raj’s equipment (DWIBS-MRI) [1:53:40]; How diffusion-weighted magnetic resonance imaging (DW-MRI) has revolutionized cancer screening [1:55:15]; Why a DW-MRI is still not a perfect test [1:59:00]; The potential for advancing MRI technology: Where does Raj think it could improve in the next 5-10 years? [2:03:00]; Are there any commercially available scanners that can match the resolution of Raj’s images? [2:06:00]; Machine learning: When and where might machine learning/AI impact the field of radiology? [2:08:40]; and More.

In this anniversary episode, Olivia, Peter's daughter who initially kicked off The Drive podcast with her sneak peek episode, returns to ask Peter the tough questions on how the podcast is going, what he has learned along the way (and how he plans to make it better), what exciting things are in store for the future, and plenty more.

In this episode, former World Series of Poker champion and author, Annie Duke, explains how poker is a pertinent model system for decision making in the real world, a system which blends imperfect information with some unknown percentage of both luck and skill. We go through the decision-making matrix, and how we spend most of our energy focusing on just one of the four quadrants at the expense of the learning opportunities that come from the other 75% of situations. Annie also shares how this evaluation of only the bad outcomes (and our tendency to judge others more harshly than ourselves in the face of a non-status quo decision), leads individuals, leaders, and teams to avoid bad outcomes at all costs. This avoidance is at the cost of the types of decisions which lead to progress and innovation both personally, and societally, across many realms from poker to sports to business to medicine. We also dive deep into a framework for learning, and the levels of thought required to rise to the top of a given domain. Finally, we talk about something that resonated deeply with me in terms of how I think about extending healthspan, which is the concept of “backcasting”. We discuss: Annie’s background, favorite sports teams, and Peter’s affinity for Belichick [7:30]; Chess vs. poker: Which is a better metaphor for decision making in life (and medicine)? [12:30]; Thinking probabilistically: Why we aren’t wired that way, and how you can improve it for better decision making [18:15]; Variable reinforcement: The psychological draw of poker that keeps people playing [25:15]; The role of luck and skill in poker (and other sports), and the difference between looking at the short run vs. long run [38:00]; A brief explanation of Texas hold ‘em [47:00]; The added complexity of reading the behavior of others players in poker [53:15]; Why Annie likes to “quit fast”, and why poker is still popular despite the power of loss aversion [58:30]; Limit vs. no limit poker, and how the game has changed with growing popularity [1:01:00]; The advent of analytics to poker, and why Annie would get crushed against today’s professionals [1:10:30]; The decision matrix, and the ‘resulting’ heuristic: The simplifier we use to judge the quality of decisions —The Pete Carroll Superbowl play call example [1:16:30]; The personal and societal consequences of avoiding bad outcomes [1:27:00]; Poker as a model system for life [1:37:15]; How many leaders are making (and encouraging) status-quo decisions, and how Bill Belichick’s decision making changed after winning two Super Bowls [1:41:00]; What did we learn about decision making from the Y2K nothingburger? And how about the D-Day invasion? [1:46:30]; The first step to becoming a good decision maker [1:48:45]; The difference between elite poker players and the ones who make much slower progress [1:55:30]; Framework for learning a skill, the four levels of thought, and why we hate digging into our victories to see what happened [1:58:15]; The capacity for self-deception, and when it is MOST important to apply four-level thinking [2:06:15]; Soft landings: The challenge of high-level thinking where there is subtle feedback and wider skill gaps [2:16:45]; The benefits of ‘backcasting’ (and doing pre-mortems) [2:19:30]; Parting advice from Annie for those feeling overwhelmed (and two book recommendations) [2:28:30]; and More.

In this episode, Jason Fung, nephrologist and best-selling author, shares his experiences utilizing an individualized approach to fasting to successfully treat thousands of overweight, metabolically ill, and diabetic patients, and why being a doctor who specializes in kidney disease gives him a unique insight into early indications of metabolic disease. We also have a great discussion on insulin resistance where Jason makes the case that we should actually think of hyperinsulinemia as the underlying problem. We also discuss the difference between time-restricted feeding, intermittent fasting, and dietary restriction (e.g., low-carb) and how they can be used to attack the root cause of T2D, metabolic syndrome, and obesity. We also have a fascinating discussion about the limitations of evidence-based medicine which leads to a conversation where we compare and contrast the scientific disciplines of medicine and biology to theoretical physics.    We discuss: Comparing scientific disciplines: Medicine and biology versus physics [7:25]; The limitations of evidence-based medicine [12:30]; Early signs of metabolic disease: How specializing kidney disease gives Jason a unique insight into early indications of illness [20:50] Insulin resistance, hyperinsulinemia, and the overflow paradigm [29:30]; Why the common treatments for type 2 diabetes seem to make things worse [42:30]; How hyperinsulinemia (not insulin resistance) drives metabolic syndrome [53:15]; Insulin and weight gain, and using fasting to empty the cells of glucose [59:30]; The two step process of developing type 2 diabetes and how they are both manifestations of hyperinsulinemia [1:03:15]; NAFLD and hyperinsulinemia: A vicious cycle [1:08:30]; Are the features and symptoms of diabetes actually protective?

In this episode, Rick Rubin, legendary music producer and co-founder of Def Jam Records and American Recordings, discusses his early foray into music production which started as a hobby as a teenager and ultimately turned into a Grammy award-winning career that produced revolutionary changes in the music industry. Rick has worked with the likes of the Beastie Boys, Red Hot Chili Peppers, and Johnny Cash, just to name a small fraction. Rick talks about the pain and suffering that sometimes drives music and the cycle of drug addiction and how he has been able to help artists through those struggles to make space for their creative genius.

In this episode, Avrum Bluming, hematologist, medical oncologist, and emeritus clinical professor at USC and Carol Tavris, social psychologist and author of Mistakes Were Made (But Not By Me), discuss their collaboration on their recent book, Estrogen Matters. Their book takes on the very polarizing and confusing topic of hormone replacement therapy for women suffering with symptoms of menopause. In many ways, the story and history of HRT is in striking parallel to the bad science that led up to the dietary guidelines being set forth in 1980. Carol and Avrum make a compelling case that most women benefit greatly from being on postmenopausal hormone replacement therapy, and can do so without increasing their risk of breast cancer.

Excited to kick off the podcast with special guest and close friend Tim Ferriss, lifehacker, podcaster extraordinaire, and author of multiple best-selling books that includes The 4-Hour Workweek, The 4-Hour Body, Tools of Titans, and Tribe of Mentors. In this podcast we cover mental health, depression, and our mutual interest in psychedelics as potential therapeutic agents. Tim talks both experientially and from his own deep dive into the literature of psychedelics and mental health. Tim is shifting his focus from investing in startups to funding experiments that he hopes will establish more reliable knowledge and therapeutic options for those suffering from anxiety, depression, and addiction. Tim also shared his list of acquired wisdom he returns to most reliably, which might be worth the price of admission alone.   We discuss: Tim’s history of depression and his TED Talk on his close call with suicide [11:15]; The type of thinking that triggers Tim’s downward spirals [17:15]; Tim’s transformative experience with ayahuasca [48:45]; How Tim’s experience and research has led him to focus on furthering the science on psychedelics and mental health [53:00]; What some of the meditation modalities, and meditation apps, are out there, why meditation can be so hard to do, but also worthwhile to stick with [1:13:00]; Why Tim made a big commitment (more than $1 million) to funding scientific research, and to psilocybin and MDMA research, in particular [1:31:00]; From all the habits and tools that Tim has learned, the five things that he returns to most reliably [2:33:00]; And more.
