Grip strength is a powerful predictor of longevity, linked to lower risks of cancer, heart disease, and all-cause mortality. Jain discusses Goodhart's Law and suggests a holistic approach to health, incorporating compound weightlifting, cardio, mobility exercises, and other health measures like waist-to-hip ratio, HbA1c, and lipids. The key takeaway is that grip strength is a side effect of a healthy, active lifestyle, not the cause of longevity. This is a public episode.

In this episode of Evolving, Nita Jain talks with Richard Sprague, a software engineer, quantified self enthusiast, and co-founder of personal health tracking startups. Sprague discusses the complexities of the microbiome, the limitations of single-point microbiome testing, and the importance of longitudinal sampling.He shares insights from his extensive self-experimentation data collection, discussing fasting, probiotics, and the impact of alcohol on glucose levels. Sprague also touches on how personal science can empower individuals to optimize their health by tailoring approaches to fit their unique biological responses.The Journey into Personal ScienceRichard Sprague's journey into personal science began with his background in software engineering and an early fascination with computers. Observing the parallels between computer systems and human biology, he developed an interest in tracking genes and other biological markers. This led him to explore how personal experimentation can inform individual health insights—a theme central to the quantified self movement.Are We Human or Are We Computers?Sprague dives into the complexities of the human microbiome—an intricate system comprising trillions of microorganisms living in and on our bodies—and emphasizes that comparing the microbiome to a computer algorithm oversimplifies its complexity. The human microbiome is a dynamic system influenced by a myriad of factors, including genetics, environment, and lifestyle.Jain and Sprague discuss the challenges of microbiome testing and the importance of longitudinal sampling to capture a more accurate picture of the gut microbiome. Richard emphasizes that single-point microbiome tests can be misleading due to the natural diurnal variation and the inherent compositional problem in sampling.Promise & Pitfalls of Microbiome TestingOne of the key pitfalls in interpreting microbiome results is the variability introduced at multiple stages of microbiome testing, from sample collection to data processing. Sprague highlights the significance of working with the same lab using consistent protocols to ensure reliable results. He also emphasizes the importance of understanding that many factors can skew microbiome readings, leading to potentially misleading conclusions.The Power of Self-ExperimentationSprague introduces the concept of personal science, or n-of-one studies, where individuals engage in self-experimentation to find what works best for their unique biology. He shares insights from his own experiments with kombucha, probiotics, and dietary interventions like fasting, highlighting how these experiences have informed his understanding of his microbiome and overall health.Embracing Curiosity and MindfulnessSprague stresses the importance of maintaining curiosity and skepticism about health practices and recommendations and encourages listeners to be mindful of their own body and health, considering personal experimentation as a powerful tool for gaining insights and making informed decisions.Subscribe to the podcast at nitajain.com!Time Stamps00:00 Richard Sprague’s Background00:45 Journey into Tech and Personal Science02:32 Complexity of Human Biochemistry vs. Computers05:24 Microbiome Testing and Its Challenges06:52 Pitfalls in Interpreting Microbiome Results16:57 Personal Science and Self-Experimentation25:06 The Impact of Microbiome on Health25:47 Personal Microbiome Discoveries27:19 Critical Windows for Microbiome Development28:00 Manipulating the Microbiome31:58 Microbiome and Disease Hypotheses36:25 Fasting and Microbiome Health39:11 Personal Science and Self-Experimentation45:17 Surprising Personal Experiment Results47:19 Conclusion and Final Thoughts This is a public episode.

In this week’s episode, writer, coach, consultant, and Ironman athlete Charlie Rogers talks about training for a triathlon, overcoming injury, maintaining an Olympic mindset, and building a portfolio career.Listen now on Apple, Spotify, Amazon Music, and YouTube.Chapter Summaries:[00:00:45] Charlie began running at the age of 14 when a coach recognized his raw talent. During his first year at university, he collapsed during a race. A cardiologist informed him that his high heart rates while running could be due to stress.[00:05:31] Biological mechanisms can help facilitate successful conditioning. Exercise creates changes in blood flow, which are detected by a protein called Piezo1. This protein then begins to remodel the vasculature in order to bring more oxygen and nutrition to your muscles, enabling them to grow and recover faster.[00:08:17] Physical exercise is necessary to keep our brains and blood vessels healthy, protect against cognitive decline, and ensure healthy longevity. Modern Western lifestyle isn't conducive to physical activity, so the onus is on us to put in the reps.[00:11:36] Charlie uses fitness trackers to record his workouts and monitor overall health. Tracking too much health data information can become overwhelming. Taking time to be present and sit in solitude can help combat data fatigue.[00:16:11] The oft-quoted goal of 10,000 steps per day has very little scientific backing and began as part of a marketing ploy for a Japanese Pedometer company in the 1960s. The typical daily step count for Charlie while training for triathlons is about 15,000.[00:19:45] We should be mindful of the risk of doing permanent bodily damage by pushing too hard during exercise. Most of us want to live longer but also maintain autonomy into later decades of life. Gaining more muscle during your 20s and 30s can help offset the 1% loss in muscle mass every year after the age of 50.[00:23:09] Charlie tracks his sleep quality using a sleep tracker on his watch but doesn't use this data to directly inform training routines. His coach, however, takes his sleep and body battery data into account.[00:28:14] Fitness trackers can be cost prohibitive and have limitations in terms of accuracy. Consumers are often faced with trade-offs between reliability and affordability.[00:31:17] The quantified self movement was born out of a desire to make sense of health data through n-of-1 experimentation. Accurately guessing our heart rates and listening to hunger cues relies on a skill called interoception, which describes our ability to sense internal signals from our bodies. We can rely on intuition while still being data-driven in our approach to health and fitness.[00:38:03] Charlie describes how he uses delayed gratification to stay motivated and push through obstacles like stomach cramps while running. Abiding by the aphorism “train hard, race easy” can help prevent lactate threshold issues.[00:42:27] Working out in a fasted state can backfire in women by blunting fat oxidation, but consuming adequate protein instead of carbohydrates before a workout can help women see more improvements in strength and lean body mass compared to post-exercise nutrition. It’s important to train with the same nutrition with which you intend to race.[00:47:00] As technology continues improving in terms of sportswear, more records will be broken. For example, Eliud Kipchoge’s shoes with carbon fiber plates allow runners to rebound faster. Accusations of doping often accompany an athlete’s rapid rise to success.[00:50:15] The gut microbiome determines how different foods and drugs are metabolized. Continuous glucose monitoring can help athletes determine which foods will keep their blood sugar levels stable and provide lasting energy.[00:54:40] Charlie has built a portfolio career as a self-employed writer, coach, and consultant. Although he’s not a professional athlete, Charlie takes his sport very seriously and invests a significant amount of time and energy into training.[00:57:33] Charlie’s Substack newsletter, Mastery in Your 20s, is a self-improvement resource detailing the business skills that one needs in order to create something meaningful in the world. Blogging a book is a great way to obtain real-time audience feedback during the writing process.[01:02:14] The Dawn of Everything dispels myths surrounding the origins of humanity and discusses the erroneous use of the “primitive” label in describing incredibly complex pre-historic societies.Connect with Charlie on LinkedIn, Strava, & Goodreads, and subscribe to his newsletter below!If you’d like to support the show, you can become a paid subscriber!
