In this conversation, they explore why strength may be far more than a physical attribute—touching on its role in brain health, cardiovascular function, and overall quality of life. Dr Keogh unpacks the evidence around resistance training and cognitive outcomes, challenges common assumptions about exercise in older adults, and discusses whether we’ve been too conservative in how we prescribe strength training across the lifespan. They also dive into the practical side of programming—what actually works, what’s often done poorly, and how to strike the balance between safety and meaningful stimulus, even in later decades. Along the way, they explore the psychological and behavioural shifts that occur when people regain strength, and why this may be one of the most powerful tools we have for supporting both physical and mental resilience as we age. This is a wide-ranging, evidence-informed discussion that reframes strength training not just as exercise, but as a cornerstone of lifelong health. Dr Justin Keogh is an exercise scientist and behavioural researcher with a strong focus on translating evidence into practical strategies that improve health, function, and performance. His work centres on the role of exercise—particularly resistance training—in mitigating treatment-related effects in cancer survivors, addressing sarcopenia in older adults, and enhancing athletic performance across a range of populations. His sports science research spans rugby union, powerlifting, sprinting, golf, and strongman, with more recent work extending into Australian rules football and swimming. He has also developed a growing research interest in female athletes, particularly in how strength and conditioning, alongside movement competency, can reduce the elevated risk of lower limb injury. Dr Keogh’s research is especially relevant to ageing populations and those affected by cancer, where he investigates how combined exercise and nutritional interventions can improve body composition, physical function, quality of life, and potentially influence disease progression. Complementing this, he has spent the past decade exploring the behavioural drivers of health, examining the barriers, facilitators, and motivations that influence physical activity and other health behaviours in older adults and cancer survivors using both quantitative and qualitative approaches. He is a Fellow of the International Society of Biomechanics in Sport and the Australian Association of Gerontology. Dr Keogh also contributes to the field through service roles on Exercise and Sport Science Australia’s Sports Science Advisory Group, the Australian Strength and Conditioning Association Conference Committee, and the Sarcopenia Diagnosis Task Force Committee for the Australian and New Zealand Society of Sarcopenia and Frailty Research.

    Mini Mikkipedia - Short Eating Windows: Why Less Time Isn’t Less Food

    In this Mini Mikkipedia episode, Mikki breaks down why short eating windows and time-restricted eating (TRE) don’t always deliver the fat loss results people expect—especially for active women. Drawing on key research, including the TREAT trial and Sutton’s early time-restricted feeding study, she explains how compressing your eating window doesn’t reliably reduce calorie intake and may even compromise body composition. Mikki also explores the interaction between exercise and appetite, highlighting how fasted training combined with delayed eating can amplify hunger signals and drive overeating later in the day. The takeaway? It’s not a willpower issue—it’s physiology. This episode offers a practical, evidence-based look at how to align nutrition with training, appetite, and real-life behaviour for better outcomes.  Highlights:  Why shorter eating windows don’t guarantee lower calorie intake  The risk of increased lean mass loss with TRE  How fasted training + delayed eating drives compensatory hunger  The difference between metabolic benefits vs real-world behaviour  Practical strategies to align eating patterns with training and appetite Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwillidenNZ listeners - save 10% off Calocurb by using the code Mikkipedia10 at www.calocurb.co.nzSave 20% on all Nuzest Products WORLDWIDE with the code MIKKI at www.nuzest.co.nz, www.nuzest.com.au or www.nuzest.comCurranz supplement: MIKKI saves you 25% at www.curranz.co.nz or www.curranz.co.uk off your first order

    Play Your Way to Better Health and Fitness - with Darryl Edwards

    Save 20% on all Nuzest Products WORLDWIDE with the code MIKKIPEDIA at www.nuzest.co.nz, www.nuzest.com.au or www.nuzest.com This week on the podcast, Mikki speaks to Darryl Edwards, movement coach and founder of the Primal Play Method, about rethinking exercise through the lens of play, biology, and human nature. In this conversation, they explore why so many adults lose their natural instinct to move, and how modern, structured exercise may be missing something fundamental. Darryl shares how playful, varied movement aligns more closely with our evolutionary design, and why this approach can support not just physical fitness, but brain function, resilience, and long-term health. They also discuss the psychology of movement—why enjoyment is often the key to consistency, and how play can shift our relationship with effort, discomfort, and motivation. Along the way, they challenge reductionist thinking in health and fitness, highlighting the broader role movement plays beyond calories burned or steps counted. This is a refreshing and thought-provoking conversation that invites a return to movement as something instinctive, engaging, and sustainable for life. Darryl Edwards MSc, FCIMSPA (Chartered), FBSLM, DFSEM(UK), DipExMed, ACSM-CES, CertLM is a London-based movement coach, author, speaker, and founder of the Primal Play Method®, an approach grounded in evolutionary biology, exercise physiology, cognitive neuroscience, and play psychology. With over 15 years of experience coaching and teaching movement, his work focuses on improving long-term adherence through practical, engaging, and sustainable activity rather than rigid exercise models.  After nearly two decades in investment banking technology, he rebuilt his own health using a back-to-basics movement approach, which now underpins his work with individuals, clinicians, educators, and organisations aiming to reduce sedentary behaviour and support both physical and mental wellbeing.  He is a Fellow of the British Society of Lifestyle Medicine, a Chartered Fellow Physical Activity and Health Practitioner with CIMSPA, a Diplomate Member of the Faculty of Sport and Exercise Medicine (UK), and an ACSM Cancer Exercise Specialist®. In 2025, he received the US Play Coalition’s Stephanie P. Garst Distinguished Service Award for his contribution to promoting physical and social health through play, and in 2026 he is a keynote speaker at Playtopia: Make Way for Play in Boston and a speaker at the ESMO Breast Cancer conference.  His TED talk, “Why Working Out Isn’t Working Out,” explores why traditional exercise often fails people and highlights the importance of enjoyable movement for long-term consistency.

    Mini Mikkipedia - Why You’re Starving at Night (And What to Do)

    If you feel in control all day but lose it at night, this episode explains why—and it’s not a discipline problem. Mikki breaks down the physiology behind evening hunger, showing how under-eating earlier in the day, low protein intake, and unstable blood glucose create a cumulative energy deficit your body is wired to correct. She explores the roles of key appetite hormones like ghrelin, leptin, GLP-1, and PYY, along with the impact of stress hormones, cognitive fatigue, and circadian rhythms. This episode reframes nighttime hunger as a predictable biological response, not a personal failure. Mikki also outlines practical strategies—like front-loading protein, structuring meals, and avoiding the “save calories for later” trap—to help regulate appetite and reduce evening overeating. Key Highlights  Why under-eating during the day drives nighttime hunger  The role of protein, GLP-1, and satiety hormones  How blood sugar dips and stress hormones amplify cravings  Circadian biology and why appetite rises in the evening  Practical strategies to stabilise hunger and prevent overeating Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwillidenNZ listeners - save 10% off Calocurb by using the code Mikkipedia10 at www.calocurb.co.nzSave 20% on all Nuzest Products WORLDWIDE with the code MIKKI at www.nuzest.co.nz, www.nuzest.com.au or www.nuzest.comCurranz supplement: MIKKI saves you 25% at www.curranz.co.nz or www.curranz.co.uk off your first order

    Philip Prins - Rethinking Carbohydrates and Endurance Perfomance

For decades, the dominant narrative has been that muscle glycogen depletion is the primary cause of fatigue during prolonged exercise, and that high carbohydrate intake is essential for sustaining performance. But Dr Prins and his colleagues revisit the evidence and ask a deeper question: is that explanation actually supported by the data? In this conversation, they explore the physiology of fatigue, the often-overlooked role of blood glucose and liver glycogen, and the phenomenon of exercise-induced hypoglycaemia as a potential driver of performance limitation. They also discuss how relatively small amounts of carbohydrate can improve performance, why higher intakes don’t always translate into better outcomes, and what this means for current high-carbohydrate fueling recommendations. Along the way, Mikki and Dr Prins unpack fat oxidation in low-carbohydrate-adapted athletes, the importance of individual metabolic differences, and whether fueling strategies for endurance athletes may need to be far more individualised than current guidelines suggest. This is a fascinating discussion that challenges long-held assumptions about carbohydrate, fatigue, and how athletes should actually fuel for performance. Dr. Philip Prins is an Associate Professor of Exercise Science. Dr. Prince earned a B.S. in Kinesiology as well as an M.S. in Exercise Science from Georgia Southern University, and a Ph.D. in Exercise Physiology from the University of Pittsburgh. His research focuses on, among other things, the practical impact of lifestyle on metabolism and how metabolism impacts health, disease and performance outcomes. Among his many areas of expertise are nutritional ketosis, metabolic responses to exercise, and sports nutrition.

    Mini Mikkipedia - Weight Loss Injections: Science, Expectations, Side Effects

    In this Mini Mikkipedia episode, Mikki breaks down the rapidly growing world of obesity pharmacotherapy, focusing on GLP-1 receptor agonists like semaglutide and the newer dual GLP-1/GIP drugs such as tirzepatide. With more people beginning these medications, understanding how they work—and how to use them effectively—has never been more important. Mikki explains the biology behind appetite regulation, the clinical trial data showing significant weight loss, and why these drugs are best viewed as long-term treatments rather than short courses. The episode also dives into the practical realities many people face once they start therapy: managing common gastrointestinal side effects, protecting muscle and bone during weight loss, and setting realistic expectations about outcomes. Whether you’re considering these medications yourself or supporting someone who is, this episode provides a clear, science-based guide to navigating the experience. Highlights: How GLP-1 and GLP-1/GIP medications regulate appetite and metabolismClinical trial results: expected weight loss with semaglutide vs tirzepatideWhy weight regain often occurs after stopping the drugsPractical strategies to manage nausea, constipation, and other GI side effectsProtecting muscle and bone with protein intake and resistance training Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwillidenNZ listeners - save 10% off Calocurb by using the code Mikkipedia10 at www.calocurb.co.nzSave 20% on all Nuzest Products WORLDWIDE with the code MIKKI at www.nuzest.co.nz, www.nuzest.com.au or www.nuzest.comCurranz supplement: MIKKI saves you 25% at www.curranz.co.nz or www.curranz.co.uk off your first order

    Beyond Calories: The Biology of Weight Regulation with Prof Eric Ravussin

    Save 20% on all Nuzest Products WORLDWIDE with the code MIKKIPEDIA at www.nuzest.co.nz, www.nuzest.com.au or www.nuzest.com This week on the podcast, Mikki speaks to Dr. Eric Ravussin, one of the world’s leading researchers in human metabolism, obesity, and energy balance. Over several decades, Dr. Ravussin’s work has helped reshape how scientists think about body weight regulation, moving the conversation beyond the simplistic idea of “calories in versus calories out” to a deeper understanding of the biology that governs appetite, energy expenditure, and fat storage. In this conversation, Mikki and Eric explore the brain’s role in regulating body weight, the influence of genetics and environment, and what his landmark research — including work with the Pima population and the CALERIE trial — has revealed about metabolic adaptation, calorie restriction, and longevity. They also discuss spontaneous physical activity, the concept of a body-weight “settling point,” and the emerging role of GLP-1 medications in obesity treatment. It’s a fascinating look at the physiology of weight regulation and why maintaining weight loss is often far more complex than most people realise. About Dr. Eric Ravussin Dr. Eric Ravussin is an internationally recognised researcher in metabolism, obesity, and energy balance. He is Associate Executive Director for Clinical Science at the Pennington Biomedical Research Center at Louisiana State University, one of the world’s leading institutions for metabolic research. For more than three decades, Dr. Ravussin’s work has focused on understanding the biological drivers of obesity and weight regulation, including energy expenditure, metabolic adaptation, appetite regulation, and the role of genetics in body weight. His research with the Pima population helped illuminate the powerful interaction between genetics and environment in the development of obesity. Dr. Ravussin has also been a principal investigator in the landmark CALERIE (Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy) trial, the first long-term randomised controlled trial examining the physiological effects of sustained calorie restriction in humans, including its potential implications for metabolic health and longevity. He has authored hundreds of scientific publications and remains a leading voice in research exploring how biology, behaviour, and environment interact to shape body weight and metabolic health.
