In this “Ask Me Anything” (AMA) episode, Peter and Bob discuss all things related to testosterone: what happens when testosterone levels are low, and the potential benefits and risks of testosterone replacement therapy (TRT). They explain the physiology of testosterone, how it works, and how its level changes over the course of a person's life. They have a detailed discussion about existing literature, which reveals vast potential structural, functional, and metabolic benefits of testosterone replacement therapy. They also take a very close look at potential risks of this therapy, with a focus on the controversial effects on cardiovascular disease and prostate cancer.

In this episode, David Epstein, best-selling author of Range and The Sports Gene, discusses the evidence around the most effective ways to improve long-term performance and learning in our specialties, our sports, our careers, and our lives. David makes a compelling case that a range of experiences and skills are more likely to lead to expert performance compared to early specialization, and offers an in-depth critique of the much-publicized 10,000-Hour Rule. David also provides insights into our role as parents in the process of encouraging exposure to many things, the concepts of when to push them, when to give them space, and when to allow them to quit. Furthermore, David goes into many other fascinating topics such as the role of talent, genetics, and practice in reaching expert status, what differentiates a kind vs. wicked learning environment, the importance of “informal training,” and many case studies that suggest strategies for short-term success may not be best for long-term development.

We discuss:

• A shared interest in Ayrton Senna, and pondering the value in participating in sports [2:30];

• Examining the 10,000-Hour Rule, and the importance of questioning existing dogma [15:00];

• How the medical profession is affected by bad science, and the importance of understanding individual variation [28:00];

• David’s most surprising findings when writing The Sports Gene [35:45];

• Kind versus wicked learning environments [40:45];

• How and why strategies for short-term success may not be best for long-term development [47:30];

• Contrasting the success stories of Tiger Woods and Roger Federer—which path is more common, and an argument for diversified training and experiences [59:15];

• Is there an age-range or “critical window” during which exposure is necessary to reach a certain level of proficiency or mastery of a skill or knowledge? [1:14:00];

• How diversifying your interests and unraveling your identity from your speciality could lead to more enjoyment and actually improve performance in your speciality [1:22:15];

• The undervalued importance of “informal training” [1:29:15];

• Advice for increasing match quality in your work—where interests and abilities align—to optimize both job performance and fulfillment [1:41:15];

• Would David want his own son to attend college given the current state of higher education? [1:51:15];

• The role of a parent—how to encourage sampling, when to push them, when to allow them to quit, and insights from the childhoods of Tiger Woods and Wolfgang Mozart [1:55:45];

• The need for varied perspectives and the ability to improvise—insights gained from the Space Shuttle Challenger tragedy [2:08:45];

• How a diversified background and identity could be the difference in life or death—the Hotshot firefighters case study [2:22:15];

• David’s takeaways from the inspiring story of Frances Hesselbein [2:29:00]; and

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];

• 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];

In this episode, Paul Grewal, internal medicine physician and co-author of Genius Foods, discusses what has got him so focused on lifestyle changes for metabolic health which was partly brought on by his own experience of losing almost 100 pounds at two points in his life. Paul and Peter discuss how the results from a NuSI-funded study has impacted their feelings about the supposed “metabolic advantage” of a low-carb diet. Paul then makes the case for what he calls the “active poisoning” of the American food supply, defines his five phenotypes of obesity manifestation, as well as lays out his nutritional and training approach with his patients (as well as himself personally). Overall, this discussion is a treasure trove of topics from endocrinology, insulin resistance, caloric restriction, fasting, exercise, causes of obesity, LDL and heart disease, and much more.

We discuss:

• Paul’s health story—two instances of major weight loss [3:15];
  
• The multiplication of adipocytes after weight loss, and why an obese adult that was overweight in childhood is harder to treat than adult-onset obesity [7:30];

• Relationship between heart disease and fatty acids (SFA, PUFA, seed oils, etc.) [1:04:30];
  
• Paul’s nutritional approach with patients [1:12:30];
  
• High-carb/low-fat diet for muscle gain, and the “reverse diet” to combat the slowdown of metabolism after caloric restriction/weight loss [1:15:00];
  
• Fasting—ideal duration, how to preserve muscle mass, and the ultimate tool of medicine [1:23:30];
  
• The 5 phenotypes of obesity, and the impact of carbs, cortisol, and sleep on adiposity [1:28:30];
  
• Uric acid [1:38:15];

In this episode, Rick Johnson, Professor of Nephrology at the University of Colorado, explains how his research into the causes of blood pressure resulted in a change of research direction to focus more on how fructose has such profound metabolic effects. Rick discusses the relationship between salt and high blood pressure, provides a masterclass into uric acid, and expertly reveals the mechanisms and pathways by which sugar (specifically fructose) can profoundly impact metabolic health. From there, he explains how he applies this information to real life patients, as well as touches on some of the most promising ideas around pharmacotherapy that are being developed in response to the epidemics of fatty liver, insulin resistance, diabetes, and obesity. Furthermore, Rick gives his take on artificial sweeteners compared to real sugar, discusses cancer’s affinity for fructose, and much more.

We discuss: 

• The connection between blood pressure and fructose that shifted Rick’s professional focus [4:00];
  
• The relationship between salt and blood pressure (and the role of sugar) [5:45];
  
• Defining fructose, glucose, and sugar [19:30];
  
• An ancient mutation in apes that explains why humans turn fructose into fat so easily [23:00];
  
• The problems with elevated uric acid levels, and what it tells us about how sugar causes disease [31:30];
  
• How sugar causes obesity—explaining the difference in glucose vs. fructose metabolism and the critical pathway induced by fructose [40:00];
  
• Why drinking sugar is worse than eating it [50:00];
  
• Unique ability of sugar to drive oxidative stress to the mitochondria, insulin resistance, and diabetes [54:00];

In this episode, Damon Hill, 1996 Formula 1 World Champion, opens up about his personal struggles with depression, feelings of inadequacy, loss of identity, and his ultimate path to healing following his remarkable racing career. Damon’s life was given a tragic jolt at 15 years of age when his father and legendary F1 driver Graham Hill died suddenly—the common string that ties together so much of his life and has forged so much of who he is to this day. We discuss Damon’s unique and remarkable racing career including his legendary battles with Michael Schumacher as well as Damon's firsthand account of what happened that tragic day on May 1st, 1994, when his teammate, Ayrton Senna, died at Imola. But this is not just about racing; rather it’s a human story that's cloaked in a racing one.

In this episode, Dr. Debra Kimless and Steve Goldner share their knowledge on the science, policy, and market evolution of medicinal cannabis. We start with the differences between THC and CBD, how they work in the body, and how they act on the brain. We discuss the many potential benefits of using CBD, THC, hemp in the various forms of administration (smoking, vaping, edibles, oils, etc.) as well as some of the safety issues including the recent uptick in incidents of hospitalization and death linked to vaping. Debra and Steve are both involved with the company, Pure Green—Debra the Chief Medical Officer and Steve the founder and CEO—whose aim is to create the safest, most efficacious form of delivery of cannabis. Their bigger mission is to shift the perception of the cannabis plant, garner acceptance of its medicinal benefits, and ultimately get it descheduled on a federal level so more people can access cannabis for a range of chronic ailments.
