Nourish Balance Thrive

There’s no doubt this is a time of uncertainty. COVID-19 has changed the way most of us live, and it’s not clear when or if we’ll be able to resume the activities we took for granted just a year ago. Rather than waiting for the government to figure it all out, our best defence against infectious disease is optimising metabolic health and immune function. For that, sleep is arguably the keystone behaviour. Today I’m joined again by our resident sleep expert, Greg Potter, PhD to talk about the effects of sleep on the immune system. Greg explains how poor sleep and sleep disorders profoundly impact the body’s ability to combat infections, including the common cold, pneumonia, and COVID-19. He also discusses the importance of getting enough sleep in the days leading up to vaccination and offers pandemic-specific tips for better sleep.

Paul Laursen, PhD is an athlete, author, endurance coach, high-performance consultant and entrepreneur. He’s published over 125 peer-reviewed papers in exercise and sports science journals, and his work has been cited more than 8,000 times. We’ve had Paul on the podcast before to talk about High-Intensity Interval Training (HIIT), as described in his book and brought to life in his online course.  On this podcast, Paul describes how he’s taken HIIT training to a new level by creating the Athletica software, to help athletes train smarter, not harder. Using the principles in his book, this software can adapt a plan based on your current fitness levels, goals, training sessions and life. As an athlete and software developer, I couldn’t resist asking Paul some tough questions about how it all works.

Over time we’ve seen an increasing number of clients come to us with symptoms of histamine intolerance, including seasonal allergies, headaches, skin issues and digestive problems. And although doctors would likely treat these as separate conditions, we believe common root causes are certainly at play. We’ve learned that histamine problems often originate in the gut, but environmental and lifestyle factors can definitely make them worse. On this podcast, NBT Scientific Director and coach Megan Hall and I discuss histamine intolerance, including causes, symptoms, and potential treatments. We talk about why this condition is difficult to diagnose, and some of the signs that suggest your “histamine bucket” is overflowing. Megan describes the best options for fixing the problem at the source, including diet, supplements, and environmental changes. Be sure to see the show notes to get the outline Megan wrote to prepare for this podcast. It’s an excellent resource for anyone who has seasonal allergies or suspects they may have histamine intolerance.

These days it’s easy to find yourself feeling tense or anxious. If social distancing and the threat of a global pandemic aren’t enough, just add a dose of political mayhem or a strained relationship and you’ve got a recipe for stress. What I’ve learned from performance psychologist Simon Marshall is that your brain and nervous system manage everything about you, including your ability to cope and overcome the difficulties of life. In this podcast, Simon and I are discussing some cutting edge ways to master your nervous system and manage stressful moments. Simon shares some evidence-based techniques that involve breathing, vocalization, and eye movement, to manage stress and help you avoid limbic system overwhelm. And as powerful as these practices are, I know they are just a few of the tools Simon has in his performance coaching arsenal. If you enjoy this podcast, I hope you’ll consider joining us in the upcoming Coping Resilience and Mental Toughness Workshop, with Simon and world champion triathlete Lesley Paterson. The workshop content is approximately five hours of prerecorded video and is largely self-paced, along with four 30-minute live group coaching sessions with Simon and Les to answer questions and help you navigate real-world situations.

David Raichlen, PhD. is a Professor of Human And Evolutionary Biology at the University of Southern California. His work explores how physical activity drove key aspects of human evolution, helping to explain how and why inactivity underlies many chronic diseases today. Combining aspects of biomechanics, physiology and neuroscience with analysis of movement patterns of ancient humans, his work helps to explain how we can use an evolutionary context to improve modern-day health. On the podcast today, David talks about the links between human evolution, physical activity, and health across the lifespan. He discusses the impact of exercise on brain health and neurogenesis and explains why an active lifestyle may be critical for those genetically predisposed to Alzheimer’s disease. He also describes the biological mechanism behind the “runner’s high” that suggests humans are “wired to run”.

Abel Romero, DPT, TPI, RYT 200 is a licensed physical therapist and movement coach with a Doctorate of Physical Therapy from UC San Francisco/San Francisco State University. He has worked with a wide range of clients, from high-performing athletes to women postpartum and seniors. He is fascinated not only with helping others achieve a high level of health and well-being, but also with the science and art of improving skill, preventing pain, and having fun through movement. On this podcast, Abel and I discuss how humans evolved to move, and the role of pain in avoiding injury. Abel talks about some of the common issues that lead to pain in our culture and why moving harder and faster is critical for long-term fitness and healthspan. I’m excited to announce Abel has partnered with us to lead a group program in January 2021. He’ll be working with us on how to avoid chronic pain, improve mobility and feel total confidence in lifting through mindful movement practice, functional training, and plyometric and power training. By the end of the program, you’ll have greater control, ability to generate power, and awareness of how your body interacts with its environment.

Mikki Williden, PhD is a Registered Nutritionist in Auckland, New Zealand specializing in sports and performance nutrition. I met Mikki at the Ancestral Health Symposium in Boulder, Colorado in 2016, and she has recently launched a new podcast called Mikkipedia as an exploration of all things health, well being, fitness, food and nutrition. She kindly invited me on as a guest, which of course is a role reversal for me. On this podcast, Mikki and I discuss my personal health journey and what motivated me to start NBT. We get into some detail, including what my life looked like before I knew anything about health and the specific steps that got me headed in the right direction. We talk about bike racing and business and how both have evolved for me, as well as the habits that I’ve built to maintain my current state of health and performance.
