Matt explains what metabolic psychiatry actually is, how it differs from conventional psychiatric approaches, and why factors like insulin resistance, inflammation, and mitochondrial dysfunction are now being considered key drivers in conditions such as depression, anxiety, and more severe psychiatric disorders.They explore the growing interest in nutritional and metabolic interventions, including dietary strategies like carbohydrate restriction, and how these may influence brain energy, neurotransmitter function, and symptom outcomes. The discussion also touches on where the evidence currently sits, what clinicians should be cautious about, and how to think about integrating these approaches alongside standard care.It's a thought-provoking conversation that challenges traditional models of mental health, while offering a more biologically grounded way of understanding and supporting the brain.Dr. Matt Bernstein is a highly respected clinical psychiatrist and a leading voice in metabolic psychiatry, with 25 years of experience helping individuals achieve full mental health and functional recovery.He graduated summa cum laude from Columbia University in English literature and earned his medical degree from the Perelman School of Medicine at the University of Pennsylvania. Trained at MGH/McLean, he served as chief resident and later held leadership roles including psychiatrist-in-charge and assistant medical director of the schizophrenia and bipolar inpatient program. He also serves as chief medical officer at Ellenhorn, developing community-based strategies to optimize mental health.For the past five years, Dr. Bernstein has focused on metabolic psychiatry, first in his private practice, and then at Ellenhorn. More recently, he created Accord's comprehensive program and is sharing his expertise through podcasts, national conferences, and briefings for members of Congress. He co-organized the first public conference on metabolic psychiatry, and co-leads a privately funded study evaluating outcomes of Accord's pioneering interventions.He serves on advisory and non-profit boards, including Metabolic Mind, Meru Health, The Metabolic Revolution, and the Coalition for Metabolic Health, helping advance the field both clinically and publicly.https://accordmh.com/our-team/matt-bernstein/ Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwilliden

In this Mini Mikkipedia episode, Mikki explores whether fruit and vegetables really “boost” immunity in the way we often hear during winter. While produce absolutely supports health, the clinical evidence suggests its immune benefits are more specific than the marketing implies, especially for those starting from a low intake. Mikki unpacks research on fruit and vegetable intake, vaccine response, vitamin C loss in stored produce, and why frozen vegetables deserve more respect. She then broadens the conversation into what actually moves the needle for immune resilience: adequate energy intake, sufficient protein, correcting true vitamin D and zinc deficiencies, and supporting gut health through fermented foods and dietary variety. The takeaway? Your immune system does not need hype; it needs enough fuel, enough protein, and the right nutrients. Tiny old-school truth bomb, really. Highlights / Topics Covered: Why “boosting immunity” is an oversimplified claim  What human trials show about fruit, vegetables, and immune function  How storage affects vitamin C in fresh produce  Why frozen vegetables can be a smart nutritional choice  The hierarchy of immune support: food, protein, vitamin D, zinc, and gut health 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

Save 20% on all Nuzest Products WORLDWIDE with the code MIKKIPEDIA at www.nuzest.co.nz, www.nuzest.com.au or www.nuzest.comThis week on the podcast, Mikki speaks to Brad Currier, Science Lead at Timeline Nutrition and lead author of the recent American College of Sports Medicine position stand on resistance training.In this episode, the conversation begins with Urolithin A and Mitopure, exploring what it is, what it does in the body, and why it has become an area of interest for mitochondrial health and muscle function. Brad explains the proposed mechanisms, the current human evidence, and what outcomes have actually been shown to improve, from cellular-level changes through to potential real-world benefits.Mikki and Brad also discuss who may be the best fit for a supplement like this, including older adults, athletes, and those already doing the fundamentals well, while also addressing the limitations of the current research and how to think about bias when science and industry intersect.The conversation then shifts to resistance training, where Brad shares key takeaways from the ACSM position stand he led, including what matters most for strength, hypertrophy, and health, and what people can probably stop overthinking.It's a balanced, evidence-informed conversation about mitochondrial health, supplementation, strength training, and the practical foundations that still matter most.Brad Currier is the Science Lead at Timeline Nutrition, where his work focuses on translating emerging research on mitochondrial health into practical, evidence-based applications. In particular, he has been closely involved in the science and communication around Urolithin A, the active ingredient in Mitopure, and its potential role in supporting muscle function, cellular energy, and healthy ageing.With a background in exercise science and resistance training research, Brad brings a dual lens to his work—combining performance-focused insights with a broader interest in longevity and metabolic health. He has contributed to large-scale evidence syntheses in resistance training, helping clarify what actually matters for strength, hypertrophy, and overall health, and where the field may have overcomplicated things.At Timeline, his role sits at the intersection of research, education, and application, helping bridge the gap between mechanistic science, clinical relevance, and real-world use—particularly as interest grows in interventions that support muscle and mitochondrial function across the lifespan.Brad Currier https://www.instagram.com/bradcurrier.phd/• ACSM Position Stand on Resistance Training (2026) - https://journals.lww.com/acsm-msse/fulltext/2026/04000/american_college_of_sports_medicine_position.21.aspx• Timeline Nutrition - https://www.timeline.com• Curranz Supplement: Use code MIKKIPEDIA to get 20% off your first order - go to www.curranz.co.nz  or www.curranz.co.uk to order yours NZ listeners - save 10% off Calocurb by using the code Mikkipedia10 at www.calocurb.co.nzContact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwilliden

In this Mini Mikkiepdia episode, Mikki takes a fresh look at omega-3 fatty acids beyond the usual “good for your heart and brain” message. She explores emerging and lesser-known research on omega-3s and their potential role in protecting muscle during immobilisation, supporting fertility and oocyte quality, reducing period pain, improving submaximal exercise efficiency, and possibly influencing dementia and colorectal polyp risk. Mikki also discusses the difference between marine omega-3s like EPA and DHA, and plant-based ALA, including surprising findings in motor neurone disease research. With practical dosing context, cautions around study limitations, and a reminder to consider omega-3 index testing, this episode is a useful listen for active people, women in perimenopause, athletes, and anyone interested in targeted supplementation. Highlights / Topics Covered: How omega-3s may reduce muscle loss during injury, surgery, or immobilisation  The role of EPA and DHA in fertility, period pain, and inflammatory pathways  Emerging research on omega-3s, APOE4, dementia risk, and brain structure  Why athletes may benefit from improved submaximal heart rate and perceived effort  Practical dosing considerations and why the omega-3 index matters 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

The discussion explores the difference between being naturally flexible and having true hypermobility, along with the often-overlooked symptoms like chronic pain, fatigue, and proprioceptive challenges. Melissa explains what's happening beneath the surface with joint stability and connective tissue, and why traditional approaches to exercise can sometimes do more harm than good.The conversation then shifts into what actually works. From strength training and motor control to pacing, recovery, and rebuilding trust in the body, Melissa shares a clear framework for managing hypermobility safely and effectively. They also touch on the role of muscle mass, nutrition, and daily habits in supporting long-term function.It's a grounded and reassuring conversation for anyone navigating a body that feels unpredictable, offering both clarity and practical direction.Melissa is a physical therapist with over two decades of experience, specialising in hypermobility, joint pain, and movement rehabilitation. She lives with hypermobile Ehlers-Danlos Syndrome (hEDS) herself, giving her a unique perspective on both the clinical and lived realities of the condition.Originally a nationally competitive level 10 gymnast, Melissa's flexibility was once a strength but ultimately contributed to a series of injuries, including a career-ending stress fracture in her lower back. Ongoing pain led her to explore different movement modalities, including Pilates, yoga, and strength and conditioning. While each offered benefits, it was the integration of these approaches that proved most effective.Melissa went on to develop the ChimeraFit method, a system that combines elements of Pilates, yoga, strength, and balance training to support people with hypermobility, arthritis, and chronic joint pain. She has been teaching this approach for over 20 years, helping individuals build strength, stability, and confidence in their bodies through safe and effective movement.https://www.instagram.com/dr.melissakoehl.pt/https://www.chimera-health.com/ground-control-september-2026-waitlisthttps://www.chimera-health.com/  Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwilliden

This week's Mini Mikkipedia takes a closer look at multivitamins, nutrient status, and whether a daily broad-spectrum supplement may support cognitive ageing. Mikki discusses the COSMOS trial, a large randomised, double-blind, placebo-controlled study that examined multivitamin use in older adults, with a particular focus on the cognitive findings from its ancillary studies. While the parent trial did not show significant benefits for cancer or cardiovascular disease, the cognitive studies found consistent benefits for episodic memory, with effects estimated to be equivalent to slowing cognitive ageing by around two to three years. Mikki also unpacks the limitations, including modest effect sizes, population generalisability, supplement formulation, and why supplements should support, not replace, the fundamentals of nutrition, exercise and sleep. Highlights: Why calorie deficits can increase the risk of micronutrient insufficiency  What the COSMOS trial tells us about multivitamins and brain ageing  The difference between observational research and randomised controlled trials  Why episodic memory may be particularly responsive to nutrient status  Why supplement quality, nutrient forms, and baseline deficiency risk matter  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

Save 20% on all Nuzest Products WORLDWIDE with the code MIKKIPEDIA at www.nuzest.co.nz, www.nuzest.com.au or www.nuzest.comThis week on the podcast, Mikki speaks to Dr Matt Nagra, a naturopathic doctor and researcher known for his evidence-based perspective on nutrition, with a particular focus on plant-based diets and chronic disease.In this episode, the conversation tackles one of the most debated topics in nutrition right now: protein. Matt helps unpack why protein has become such a focal point, how to interpret the current evidence, and what outcomes actually matter when we're talking about intake and health. They explore the long-standing protein RDA and what it was designed to represent.The discussion then moves into protein quality, addressing common claims around plant versus animal protein, and why mechanistic research doesn't always align with long-term health outcomes. Matt also provides important context around dietary patterns and chronic disease risk, helping to separate the role of protein itself from the broader way people eat.They finish with a dive into choline, covering its role in the body, how it interacts with other nutrients like folate and betaine, and what this means for people following predominantly plant-based diets.It's a thoughtful, nuanced conversation that cuts through the noise and brings clarity to some of the biggest questions in modern nutrition.Dr Matt Nagra is a naturopathic doctor who graduated from the Boucher Institute after completing a Bachelor of Science in Microbiology at the University of Victoria. He holds additional board certifications in prescriptive authority, immunisations, advanced injection therapies, intravenous therapies, and acupuncture.

In this Mini Mikkipedia episode, Mikki explores the concept of metabolic memory—a powerful and often overlooked driver of long-term health. Drawing on landmark studies like DCCT and UKPDS, she explains how periods of poor metabolic health can leave a lasting imprint, continuing to influence disease risk even after markers like blood glucose are brought back under control. But it's not all bad news. Mikki also unpacks the flip side: how positive adaptations from training, nutrition, and metabolic challenges can create a beneficial “memory” that helps the body rebound faster and perform better over time. From epigenetics to mitochondrial function, this episode highlights why timing matters and why early intervention—and consistency—can shape your metabolic future. Highlights: What metabolic memory is and where the concept originated  The “legacy effect” in diabetes research and why early control matters  Cellular mechanisms: epigenetics, oxidative stress, and AGEs  The positive side: training, ketosis, and metabolic flexibility  Why your past habits—good or bad—continue to influence your health 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

Don walks through the historical context behind early guidelines, including where things may have gone off track, particularly around the treatment of fat, cholesterol, and protein-rich foods.From there, the discussion moves into the science. Don outlines the limitations of relying heavily on observational nutrition research and contrasts this with findings from controlled trials, particularly in relation to protein requirements and metabolic health. He explains why he recommended a shift to the new protein targets to better support muscle, satiety, and overall health.Dr. Donald Layman is Professor Emeritus in the Department of Food Science & Human Nutrition at the University of Illinois at Urbana-Champaign.

In this Mini Mikkipedia episode, Mikki breaks down one of the most persistent nutrition debates: are high-protein diets actually harmful? Drawing on a recent perspective paper published in the American Journal of Clinical Nutrition, she unpacks common claims around kidney damage, bone loss, diabetes risk, and reduced longevity. Rather than dismissing concerns outright, Mikki walks through what the research truly shows, highlighting key methodological flaws, the limits of observational data, and the importance of context. From overfeeding studies to real-world dietary patterns, this episode challenges headline-driven narratives and brings nuance back into the conversation. If you've ever questioned whether your protein intake is “too high,” this is a grounded, evidence-informed discussion to help you cut through the noise and make more confident decisions.Highlights: Why the “protein turns to fat” claim doesn't hold up in real-world studies  The truth about protein intake and kidney health in healthy individuals  How higher protein diets impact bone density and fracture risk  The nuance behind protein, insulin resistance, and type 2 diabetes  Why observational data often misleads protein-related health claims 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

This week, Mikki breaks down one of the most common (and misunderstood) questions in fat loss and health: what should your body fat percentage actually be? Drawing on current research, she explains why body fat isn't just “dead weight” but an active endocrine organ that plays a critical role in metabolism, hormones, and overall health. Mikki unpacks the difference between subcutaneous and visceral fat, why where you store fat matters, and how risk increases at higher levels. She also explores the lack of a universal “ideal” number, highlighting how factors like age, sex, and ethnicity influence healthy ranges. Finally, she cuts through the noise on body composition measurements, from DEXA to BIA, and offers practical guidance on what to focus on instead of chasing a single number. Key Highlights: Why body fat is metabolically active and essential for health  The critical difference between subcutaneous and visceral fat  Evidence-based body fat ranges for men and women  Limitations of common measurement tools like BIA and DEXA  Why health is more than just a body fat percentage  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

Prof Scott unpacks why muscle mass and function are critical for healthy ageing, and how this becomes increasingly complex in the context of obesity, weight loss, and modern treatment approaches.Mikki and Prof Scott explore the tension between improving metabolic health and preserving muscle, including what happens to lean mass during weight loss and why muscle quality matters as much as quantity. They also discuss practical strategies around resistance training and protein, and how these may need to shift across the lifespan.The discussion then turns to GLP-1 receptor agonists and their growing role in obesity management, examining what we know so far about their impact on muscle mass, strength, and long-term health outcomes.This is a broad, evidence-based conversation that brings muscle back to the centre of the metabolic health discussion, with clear takeaways for both clinicians and individuals.David Scott is a Professor of Clinical Epidemiology at Monash University, with a research focus on musculoskeletal health, ageing, and body composition.His work centres on understanding and preventing age-related declines in muscle mass and function, including sarcopenia and frailty. He has a particular interest in how lifestyle factors such as nutrition, physical activity, and body weight influence muscle quality, strength, and overall functional capacity across the lifespan.Professor Scott's research also explores the intersection of obesity and muscle health, including the concept of sarcopenic obesity, as well as the effects of weight loss and emerging therapies on lean mass and physical function. His work contributes to the development of evidence-based strategies to support healthy ageing, maintain independence, and reduce the burden of chronic disease.Professor Dave Scott: https://www.monash.edu/medicine/scs/researchers/david-scott  Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwilliden

This week, Mikki breaks down a major 2025 study using UK Biobank wearable data to challenge one of the most widely accepted rules in exercise science. For decades, we've been told that one minute of vigorous activity equals two minutes of moderate activity. But the data tells a very different story. Drawing from over 73,000 participants, this episode unpacks how vigorous movement may be four to ten times more effective depending on the health outcome. Mikki explains what actually counts as “vigorous” (it's more accessible than you think), the physiological mechanisms driving these benefits, and how small bursts of effort throughout your day can meaningfully impact long-term health. This is a practical, evidence-based rethink of how to approach movement for metabolic health, cardiovascular fitness, and longevity.Key Highlights: Why the long-standing 1:2 activity ratio doesn't hold up  What “vigorous” really means in real-world terms  How short bursts of effort impact cardiovascular and metabolic health  The surprising limits of light activity for disease risk reduction  Practical ways to incorporate high-value movement into daily life 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

Save 20% on all Nuzest Products WORLDWIDE with the code MIKKIPEDIA at www.nuzest.co.nz, www.nuzest.com.au or www.nuzest.comThis week on the podcast, Mikki speaks to returning guest Associate Professor José Areta to unpack one of the most debated topics in sports nutrition: energy availability, and what really happens when intake drops below demand.José takes a clear, physiology-first approach to explaining what energy availability actually means, why it has become such a dominant concept in exercise science, and whether the current narrative has become overly black-and-white. They explore his recent study examining the effects of a short, aggressive energy deficit, including what happens not just at a whole-body level, but deep within muscle tissue itself.In this conversation, they discuss the hormonal and metabolic responses to rapid weight loss, surprising findings around mitochondrial protein synthesis, and what changes in muscle and connective tissue might actually represent. José also reframes energy deficit as a biological stressor — one that may be adaptive in the right context — and challenges assumptions around how common and harmful low energy availability truly is.This is a nuanced, evidence-driven discussion that cuts through the noise and offers a more balanced perspective on energy deficit, performance, and long-term health.José L Areta currently works as an associate professor in Sports Nutrition and Metabolism at the School of Sport and Exercise Sciences at LJMU.José examines how nutrition interacts with exercise to shape both performance and health, with a focus on macronutrient timing and composition, the role of supplements in optimisation, and the hormonal and metabolic responses to energy restriction.José can be found at:https://profiles.ljmu.ac.uk/13460-jose-areta Paper: https://pubmed.ncbi.nlm.nih.gov/41182317/Previous appearance https://podcast.mikkiwilliden.com/124  Curranz Supplement: Use code MIKKIPEDIA to get 20% off your first order - go to www.curranz.co.nz  or www.curranz.co.uk to order yours NZ listeners - save 10% off Calocurb by using the code Mikkipedia10 at www.calocurb.co.nzContact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwilliden

In this Mini Mikkipedia episode, Mikki unpacks one of the most common yet misunderstood issues in modern health: the interplay between cortisol, stress, poor sleep, and elevated heart rate. Using a real community question as the foundation, she explains why feeling “wired but tired” isn't a personal failing, but a physiological response to chronic, unresolved stress.Mikki walks through how cortisol actually works, why both exercise and life stress use the same biological pathways, and what happens when your system never fully downregulates. She also explores the role of the HPA axis, autonomic nervous system imbalance, and why tools like HRV and resting heart rate can offer insight—but also create more stress if misused.Most importantly, this episode delivers practical, evidence-based strategies to help restore balance and build resilience. Key Highlights: Why cortisol is not the villain—and what it actually does  The difference between acute stress and chronic, unresolved stress  What a high morning heart rate is really telling you  How lifestyle, hydration, and training load impact your stress response  Practical tools to downregulate your nervous system 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

This week on Mini Mikkipedia, Mikki breaks down one of the most misunderstood topics in fat loss: the difference between visceral fat and stubborn subcutaneous fat. While often lumped together, these two fat types behave very differently—and require completely different strategies.Mikki explains why visceral fat, despite being more harmful metabolically, is actually easier to lose and highly responsive to aerobic exercise—even without weight loss. She also unpacks why stubborn fat (think lower belly, hips, thighs) is slower to shift, driven by different receptor biology and requiring sustained consistency over time.This episode is especially relevant for women navigating perimenopause, where hormonal changes can shift fat distribution without changes on the scale. If you've been frustrated by lack of progress, this conversation will help you understand what's really going on—and what to do next. Highlights: Why visceral fat is dangerous—but easier to lose  The hormonal drivers of fat redistribution in perimenopause  Why aerobic exercise outperforms resistance training for visceral fat  The physiology behind “stubborn” fat and why it resists change  Practical strategies to target both fat types effectively 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

Save 20% on all Nuzest Products WORLDWIDE with the code MIKKIPEDIA at www.nuzest.co.nz, www.nuzest.com.au or www.nuzest.comThis week on the podcast, Mikki speaks to Dr Jocelyn Wittstein, orthopaedic surgeon and researcher, about the often overlooked intersection between nutrition, metabolism, and musculoskeletal health in women.With a background that uniquely bridges nutrition and medicine, Dr Wittstein brings a broader lens to joint, bone, and tendon health—moving beyond purely mechanical explanations to explore how lifestyle, dietary patterns, and metabolic health shape outcomes across the lifespan. In this conversation, they dive into why conditions like frozen shoulder disproportionately affect women in midlife, the role of oestrogen in tissue resilience, and how shifts during menopause influence muscle, bone density, and injury risk.They also unpack the impact of protein intake on musculoskeletal integrity, alongside the emerging links between insulin resistance, inflammation, and joint health. This is a practical and thought-provoking discussion that reframes menopause as not just a reproductive transition, but a critical window for protecting long-term strength, mobility, and resilience.Dr. Wittstein is a practicing orthopaedic surgeon, researcher, and associate professor at Duke University specialising in sports medicine and the female athlete across the lifespan. She's also a former collegiate gymnast and mother of five. Her research focuses on frozen shoulder, ACL injuries in female athletes, and the musculoskeletal syndrome of menopause. As president of the Forum for Women in Sports Medicine, Dr. Wittstein is changing how we understand the intersection of hormones, movement, and independence in women's bodies.Jocelyn Ross Wittstein, MD (Duke Health)Jocelyn Wittstein, MD (Instagram) “The Complete Bone and Joint Health Plan: Help Prevent and Treat Osteoporosis and Arthritis,” by Dr. Jocelyn Wittstein and Sydney Nitzkorski, MS, RD Curranz Supplement: Use code MIKKIPEDIA to get 20% off your first order - go to www.curranz.co.nz  or www.curranz.co.uk to order yours NZ listeners - save 10% off Calocurb by using the code Mikkipedia10 at www.calocurb.co.nzContact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwilliden

In this Mini Mikkipedia episode, Mikki breaks down a newly published narrative review examining whether menopause truly slows metabolism. While the common narrative suggests an inevitable metabolic decline, the reality is far more nuanced. Mikki walks through the evidence on resting metabolic rate, fat oxidation, physical activity, and sleep—highlighting where menopause may play a role and where age, muscle mass, and behaviour are more influential. She also unpacks a key overlooked factor: sleep disruption, and its downstream effects on fat oxidation and energy balance. Importantly, this episode challenges the idea that menopause overrides energy balance, instead reinforcing that foundational habits—muscle maintenance, movement, protein intake, and sleep—remain the primary drivers of metabolic health. A grounded, evidence-based take for women navigating midlife changes.Key Highlights: Why resting metabolic rate changes are inconsistent—and often linked to muscle mass, not menopause  The role of reduced fat oxidation and what it actually means for fat gain  How sleep disruption (and progesterone) may influence metabolism  Declines in physical activity: hormonal vs behavioural drivers  Practical strategies to maintain metabolic health through menopause Article https://pubmed.ncbi.nlm.nih.gov/41860241/ 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

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.Justin bio https://research.bond.edu.au/en/persons/justin-keogh/Podcast Stronger Through the Ages https://open.spotify.com/show/69bzn3LApQ9ohOmx2Q26sN  Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwilliden

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

Save 20% on all Nuzest Products WORLDWIDE with the code MIKKIPEDIA at www.nuzest.co.nz, www.nuzest.com.au or www.nuzest.comThis 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®.

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.Darryl Edwards: https://www.primalplay.com/who-is-darryl-edwards Curranz Supplement: Use code MIKKIPEDIA to get 20% off your first order - go to www.curranz.co.nz  or www.curranz.co.uk to order yours NZ listeners - save 10% off Calocurb by using the code Mikkipedia10 at www.calocurb.co.nzContact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwilliden

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

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.Dr Prins can be found here: https://www.gcc.edu/Home/Academics/Faculty-Directory/Faculty-Detail/philip-prins Dr Prins Researchgate: https://www.researchgate.net/profile/Philip-PrinsStudy https://academic.oup.com/edrv/article/47/2/191/8432248 Previous podcasts https://podcast.mikkiwilliden.com/190 and https://podcast.mikkiwilliden.com/348  Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwilliden

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

Save 20% on all Nuzest Products WORLDWIDE with the code MIKKIPEDIA at www.nuzest.co.nz, www.nuzest.com.au or www.nuzest.comThis 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 RavussinDr. 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.Prof Ravussin's faculty profile:https://www.pbrc.edu/research-and-faculty/faculty/Ravussin-Eric-PhD.aspx  Curranz Supplement: Use code MIKKIPEDIA to get 20% off your first order - go to www.curranz.co.nz  or www.curranz.co.uk to order yours NZ listeners - save 10% off Calocurb by using the code Mikkipedia10 at www.calocurb.co.nzContact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwilliden

In this conversation, she brings her trademark ability to connect physiology with lived experience, unpacking why she so often says, “fix iron first.”Together, they explore iron beyond the anaemia narrative — diving into its role in neurotransmitter production, thyroid function, metabolism, perimenopause, and even ADHD. They discuss why iron deficiency remains under-recognised in teenage girls and health-conscious women alike, how inflammation and gut health can silently impair absorption, and why wide reference ranges don't always reflect optimal wellbeing.Dr Libby also shares practical insights on testing, common absorption mistakes, and the health stories women need to stop accepting as “normal.” This is a grounded, physiology-first discussion that reframes fatigue, anxiety and “just hormones” through a biochemical lens — and offers clear, practical takeaways for women who want to feel genuinely well, not just told they're normal.Libby https://drlibby.com/pages/about-dr-libbyBioblends (incl iron) https://www.bioblends.com/  Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwilliden

Is breakfast really the key to weight loss—or is that just a decades-old narrative we've never properly questioned?In this Mini Mikkipedia episode, Mikki unpacks what the highest-quality research actually says about breakfast and fat loss. While observational data suggests breakfast eaters tend to be leaner, randomized controlled trials tell a different story: simply adding breakfast doesn't cause weight loss—and may even increase daily calorie intake.But that's not the end of it. When we zoom in on meal timing and breakfast composition, a more useful pattern emerges. A protein-rich, substantial breakfast eaten earlier in the day may improve appetite regulation, reduce evening overeating, and support long-term adherence to a calorie deficit.If you've ever wondered whether you “should” be eating breakfast for fat loss, this episode delivers the nuance you actually need.What You'll LearnWhy RCTs show breakfast alone doesn't drive weight lossHow front-loading calories can improve hunger regulationThe 30g protein + 350 calorie breakfast thresholdWhy meal timing affects appetite more than metabolismWhen skipping breakfast might still work

Sign up to my free unlocking fat loss succeess webinar: https://www.mikkiwilliden.com/unlocking-fatloss-success Artificial sweeteners—especially aspartame—have become one of the most controversial topics in nutrition. Does aspartame spike insulin? Trigger hunger? Disrupt metabolism? Increase diabetes risk?In this Mini Mikkipedia episode, Mikki breaks down a comprehensive meta-analysis published in Advances in Nutrition reviewing over 100 human randomized controlled trials on aspartame. The findings challenge many of the common narratives circulating online.You'll learn what actually happens to blood glucose, insulin, appetite hormones, and calorie intake when people consume aspartame—and why the feared “insulin spike without glucose” mechanism doesn't hold up physiologically.

She clarifies the difference between occasional overeating and true binge episodes, including the defining feature of loss of control, and outlines the DSM-5 criteria for binge eating disorder (for education, not self-diagnosis). Mikki then unpacks the physiology and psychology driving the restriction–binge cycle: dopamine and reward circuitry, cortisol and stress, shifts in ghrelin and leptin during calorie deficits, and the classic “what-the-hell effect” described in restraint theory. Most importantly, she offers practical strategies — predictable meals, adequate protein and energy, flexibility over rigidity, understanding whether you're a moderator or abstainer, and building alternative coping tools — so you can decide whether fat loss is appropriate now or if foundational work comes first.HighlightsBinge eating vs overeating: the critical differenceDSM-5 criteria explained clearly and practicallyWhy calorie restriction increases biological pressure to overeatRestraint theory and the “what-the-hell” effectPractical steps to break the restriction–binge cycle Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwillidenSave 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

Most people don't quit fat loss at the start, when motivation is high, or at the end, when results are obvious. They quit in the middle. In this Mini Micropedia episode, Mikki unpacks why the middle phase of fat loss feels so uncomfortable, confusing, and tempting to abandon—and why it's actually where success is decided. Drawing on Seth Godin's concept of The Dip, Mikki explains how slowing scale changes, rising hunger, reduced novelty, and fuzzy feedback loops can make perfectly normal progress feel like failure. She breaks down the physiological and psychological shifts that happen during sustained fat loss, the three common lies people tell themselves in the middle, and why chasing a “new plan” is usually the worst move. This episode reframes the middle not as a problem to fix, but as the work itself—and shows how staying the course builds habits, self-trust, and sustainable results.Highlights / Topics CoveredWhat “The Dip” is and why it shows up in fat lossWhy slow progress doesn't mean stalled progressThe three lies that derail people mid-journeyReframing success as adherence, not scale movement Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwillidenSave 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

Molly specialises in working with women whose services are ahead-of-their-time—paradigm-shifting, often unseen, and not always easily explained by mainstream frameworks.In this conversation, Mikki and Molly explore energy healing and its impact on health, intuition, and decision-making, as well as the interplay between masculine and feminine energy in life and business. This episode is a grounded, thoughtful discussion for anyone navigating the space between intuition, embodiment, and running a financially viable business.Molly Hamill is a business energetics intuitive and mentor who supports female business owners to transform their inner knowing into income—without diluting the depth of their work. She is best known for working with women whose offerings sit outside the mainstream: energy healers, intuitive practitioners, coaches, and service providers whose work is often misunderstood, invisible, or difficult to articulate in conventional business language.After building a successful Reiki healing and coaching practice that allowed her to leave a senior corporate executive role, Molly experienced firsthand the tension many women feel between deep service and talking about money. While she knew her work was changing lives, learning how to communicate her offers, value, and pricing in a way that felt aligned—not performative or fear-based—became a turning point in her career.Today, Molly bridges intuition and strategy, helping women understand how energetic alignment, emotional intelligence, and balanced masculine–feminine dynamics underpin both impact and financial sustainability.

Is body fat gain simply “calories in, calories out”—or is insulin the real puppet master? In this Mini Micropedia episode, Mikki unpacks the loudest argument in nutrition science and explains why both camps are touching real physiology… but neither tells the full story alone. You'll hear what the carbohydrate–insulin model (CIM) actually claims, how insulin resistance works at the cellular level (IRS/PI3K/AKT, lipid intermediates, inflammation), and why insulin affects appetite, satiety, and nutrient partitioning. Mikki also uses classic refeeding data (including the Minnesota Starvation Experiment and modern refeeding trials) to show that rising insulin doesn't automatically mean instant fat gain—energy balance still sets the boundary conditions. The practical takeaway: target a calorie deficit, but design it to improve insulin sensitivity and keep hunger manageable.Highlights / topics coveredWhat the carbohydrate–insulin model gets right (and where it overreaches)Insulin resistance mechanisms: ectopic fat, DAG/PKC signalling, inflammationAppetite regulation: central insulin resistance, leptin signalling, food rewardRefeeding lessons: glycogen/lean tissue restoration vs “insulin = fat gain”The integrated model: calories as the constraint, insulin as the difficulty dial Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwillidenSave 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

This week on Mini Mikkipedia, Mikki unpacks one of the most counter-intuitive truths in fat loss: eating better often means eating more food, not less. Many people equate weight loss with shrinking portions and constant restriction, yet this approach usually backfires. In this episode, Mikki explains the critical difference between food volume and energy density, and why swapping ultra-processed, calorie-dense foods for whole, nutrient-dense meals leads to greater satiety, quieter hunger, and more consistent fat loss.She explores how protein, fibre, and meal structure work together to reduce grazing, decision fatigue, and “food noise,” while supporting long-term weight maintenance. If fat loss has felt like white-knuckling through hunger, this episode reframes success as eating adequately, calmly, and sustainably—without relying on willpower or deprivation.Key Topics CoveredVolume vs energy density and why plate size can increase while calories dropThe role of protein and fibre in satiety and appetite regulationHow under-eating drives grazing, snacking, and food noiseWhy structured meals beat constant restraint for long-term fat loss Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwillidenSave 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

We love supplements for their promise of better sleep, recovery, gut health, and performance—but what happens when they don't work the way they're supposed to? In this Mini Mikkipedia episode, Mikki unpacks why evidence-based supplements like magnesium, melatonin, probiotics, and creatine can have very different effects from person to person.You'll learn why magnesium threonate and glycinate can feel stimulating instead of calming, why melatonin's dose-response is often counterintuitive, how probiotics can miss the mark without strain specificity, and why creatine may worsen bloating, sleep, or luteal-phase symptoms for some women—especially in perimenopause.The key message: “evidence-based” does not mean universally effective. Individual physiology, hormones, stress, fuel availability, and life stage matter. This episode is about applying nutrition science in the real world—where context and self-monitoring trump supplement dogma.Key Topics & HighlightsWhy magnesium can improve sleep—or disrupt itMelatonin: when lower doses work better than higher onesThe problem with generic, shotgun probioticsCreatine, fluid retention, and sleep in perimenopauseHow to troubleshoot supplements instead of blindly persisting Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwillidenSave 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

They discuss the physiology that keeps the body stuck in survival rather than being able to heal. They also dive into peptides, what is and isn't appropriate and Curtis' recommendations for out of the box treatments. Curtis Gillespie Sayers is a health practitioner and systems thinker specialising in mitochondrial health, nervous system regulation, and recovery from chronic illness.After spending much of his early life in and out of hospital with significant respiratory and cardiometabolic complications — including severe sleep apnoea, hypertension, dyslipidaemia, and pre-diabetic markers — Curtis entered the health space initially through bodybuilding. While improving his physique helped some symptoms, it also revealed a deeper truth: external fitness does not guarantee internal health.Driven by a desire to understand what was happening beneath the surface, Curtis shifted his focus toward the interaction between mitochondria, the nervous system, immune signalling, and environmental inputs such as light, sleep, and stress. His work now centres on helping people who feel “stuck” — those who have tried diets, supplements, and protocols without lasting improvement — by addressing the biological signals that determine whether the body can actually heal.Curtis takes a pragmatic, data-informed approach, viewing tools like nutrition, supplements, and peptide therapy as supportive levers rather than shortcuts, and emphasising the importance of safety, adequacy, and rhythm in long-term recovery.Curtis https://lifestylempowerment.ca/Curtis https://www.instagram.com/funct.med.curtis/ Curranz Supplement: Use code MIKKIPEDIA to get 20% off your first order - go to www.curranz.co.nz  or www.curranz.co.uk to order yours Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwilliden

Can zinc genuinely improve sleep—or is it just another supplement riding good marketing? In this Mini Mikkipedia episode, Mikki unpacks what the research actually shows about zinc and sleep, with a specific lens on midlife women and endurance athletes. She walks through the proposed mechanisms—GABA-A receptor modulation, neurotransmitter balance, melatonin synthesis, and circadian rhythm regulation—before cutting to the critical point: zinc only appears to improve sleep when it corrects a deficiency. Drawing on a 2024 systematic review of randomised trials, Mikki explains why benefits show up in populations like older adults, shift workers, and clinical patients, but not in well-nourished athletes using ZMA. The episode also covers zinc deficiency risk factors, menopause-specific considerations, copper–zinc balance, testing strategies, and practical dosing guidance—so listeners can make evidence-based decisions rather than chasing “super sleep” promises.Key Topics CoveredHow zinc influences sleep physiology (GABA, melatonin, circadian genes)What human trials actually show about zinc supplementation and sleepWhy ZMA fails in well-nourished athletesZinc deficiency risk in athletes and midlife womenCopper–zinc ratio, testing, and safe supplementation guidelines Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwillidenSave 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

They discuss the difference between body awareness and body trust and how historical and cultural medical narratives shape the way women interpret symptoms.The conversation also challenges the idea that health must always be pursued at the level of optimisation, introducing the concept of being “healthy enough”—not as a lowering of standards, but as a way of letting health support life rather than dominate it.This episode will resonate with anyone who has felt exhausted by the constant focus on hormones, symptoms, and self-improvement, and is looking for a more grounded, humane way to think about women's health.Lara Briden is a naturopathic doctor and bestselling author of the books Period Repair Manual and Hormone Repair Manual — practical guides to treating period problems with nutrition, supplements, and bioidentical hormones. With a strong science background, Lara sits on several advisory boards and is the lead author of a 2020 paper published in a peer-reviewed medical journal. She has more than 20 years' experience in women's health and currently has consulting rooms in Christchurch, New Zealand, where she treats women with PCOS, PMS, endometriosis, perimenopause, and many other hormone- and period-related health problems.Reach Lara at www.larabriden.com, IG: https://www.instagram.com/larabriden/Lara's books  https://larabriden.com/lara-briden-books/Lara's previous appearance on Mikkipedia https://podcast.mikkiwilliden.com/33  and https://podcast.mikkiwilliden.com/248 and https://podcast.mikkiwilliden.com/264  Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwilliden

In this first Mini-Mikkipedia of 2026, Mikki breaks down why fat gain—especially around the midsection—can occur even when you're “doing everything right” on paper. Tracking calories, training consistently, and eating well may still fall short if chronic stress is driving the hormonal environment. This episode unpacks the physiology behind stress-induced fat storage, with a particular focus on cortisol, visceral adiposity, and disrupted fuel partitioning. Mikki explains why stressed bodies are more likely to lose muscle, store abdominal fat, and struggle with fat oxidation—despite being in a calorie deficit. She also explores how under-eating, poor sleep, and excessive training compound the problem, creating a metabolic perfect storm. The key takeaway: stress management isn't optional. It's a foundational pillar of metabolic health, fat loss, and long-term body composition success.Key Topics CoveredHow chronic cortisol drives visceral fat storageFuel partitioning: why stressed bodies burn muscle, not fatWhy eating less and training more can backfire under stressThe role of sleep, recovery, and energy availability in fat lossPractical stress-management strategies that actually move the needle Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwillidenSave 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

Kyal unpacks his core philosophy that many of today's health challenges are predictable outcomes of the environments and lifestyles we now inhabit—and why targeted supplementation and protocols may be necessary to offset those exposures.They explore peptides as a bridge between naturopathic and conventional medicine, including when they are appropriate, how delivery routes change outcomes, and how to differentiate common compounds like BPC-157, GHK, KPV, and lorazotide. They discuss  GLP-1 agonists—their risks, misconceptions, gut-motility paradoxes, and why “fixing the gut first” is non-negotiable, and much more.Kyal Van Der Leest is a qualified Nutritionist, Naturopath, and functional health strategist with a deep-rooted passion for human optimisation and evidence-based supplementation. He is the founder and formulator behind LVLUP Health, a science-driven wellness brand dedicated to developing advanced practitioner-grade supplements that support the body's innate healing systems. Kyal's journey into health innovation began in clinical and retail environments—including hyperbaric oxygen therapy and high-volume supplement settings—where he saw firsthand the limitations of conventional products and protocols. This sparked his mission to create targeted formulations that combine clinically relevant compounds, peptides, and high-quality actives to simplify and enhance health outcomes. Today his products are stocked globally and recognised for their efficacy within both practitioner and biohacking communities.

As the year wraps up, this Mikkipedia episode invites you to pause—not to reinvent yourself, but to reassess what's no longer serving you. Rather than buying into “New Year, New You,” Mikki reframes this season as a strategic checkpoint. She explores what it might look like to let go of outdated training practices, rigid nutrition rules, chronic restriction, unexamined supplement habits, and an overreliance on data.The episode also tackles the less obvious clutter: self-limiting identity narratives, all-or-nothing thinking, guilt around rest, and the pervasive belief that perimenopause equals inevitable decline. Finally, Mikki turns to the modern challenge of our digital diet—fear-based health content, conflicting advice, and chronic doom-scrolling—and explains why curating your information intake matters as much as curating your training or nutrition.This is about creating space for strategies that fit where you are now—and letting the rest go.Key Topics CoveredWhen fasted training and fasting stop being strategicThe hidden cost of chronic restriction, junk miles, and overtrainingReleasing self-limiting identity stories and comparison to your past selfLetting go of guilt around rest, recovery, and changing capacityCurating your digital diet to reduce stress and decision paralysis Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwillidenSave 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

A former broadcaster turned software developer based in Dunedin, Brendan describes a lifelong struggle with weight, the shame and “try harder” messaging, and the moment he realised the issue wasn't a character flaw—it was the advice. After being pointed toward Professor Tim Noakes and a low-carb approach, Brendan ran a deliberate self-experiment: change the food first, track the results, and let hunger be the guide. The payoff wasn't just the scale—it was satiety, routine, confidence, and a practical framework for staying the course when life (and “eat normal”) pressure shows up.Highlights / topics coveredWhy “eat less, move more” failed him—and what shifted when the food changed firstThe early wins: scales, clothing fit, and appetite finally calming down“Success over compliance”: choosing what works over what's orthodoxBuilding guardrails: simple routines, fewer decisions, and sustainable structureNavigating social pressure, setbacks, and the long game of metabolic health Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwilliden

In this Mini Mikkipedia episode, Mikki breaks down a refreshingly sane approach to Christmas eating — one that ditches guilt, detoxes, and “earning your food,” and instead works with your physiology. Using a simple three-phase framework — Prime, Process, Restore — Mikki explains how small, practical behaviours before, during, and after Christmas Day can dramatically improve blood sugar control, digestion, energy, and overall metabolic resilience. From protein-anchored meals and strategic movement to post-meal walks and nervous system regulation, this episode is about supporting the machinery that handles abundance — not punishing yourself for it. No calorie counting, no biohacker gadgets, no January regret. Just evidence-based habits that help you enjoy Christmas as a celebration, not a metabolic crisis.HighlightsWhy Christmas food isn't “good” or “bad” — and why behaviour ≠ characterHow movement primes insulin sensitivity and glycogen storageThe power of protein anchoring to prevent dysregulated eatingWhy post-meal walks are non-negotiable metabolic goldHow stress and guilt impair digestion more than food ever could Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwillidenSave 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

Save 20% on all Nuzest Products WORLDWIDE with the code MIKKIPEDIA at www.nuzest.co.nz, www.nuzest.com.au or www.nuzest.comThis week on the podcast, Mikki speaks to Dr Lise Alschuler — a naturopathic oncologist, professor of clinical medicine, and one of the most respected voices in integrative cancer care worldwide. Dr Alschuler is known for bridging rigorous evidence with deeply human practice, helping people navigate not just cancer treatment, but the long arc of survivorship that follows. Her work spans circadian biology, metabolic health, botanical therapeutics, lifestyle medicine, and the psychology of living well after cancer.Their conversation travels through the evolving landscape of survivorship, delves into what high-quality follow-up care actually looks like, how to integrate whole-person philosophy within a conventional and often fragmented medical system, and what an ideal post-treatment care pathway would include. From insomnia to fatigue, melatonin to magnesium, morning light to meal timing, they unpack the practical tools that genuinely help restore circadian regulation — and why circadian disruption is far more consequential than most oncology guidelines acknowledge.They also explore exercise as a survival enhancer, how to guide intensity safely for those wary of over-exertion, and why maintaining muscle may be one of the most under-recognised cancer-prevention strategies. Adaptogens, botanicals, and supplement selection all feature, with clear insight into what works, for whom, and where caution is needed.They close with a deep dive into insulin resistance, nutrition strategies, carbohydrate restriction, soy, alcohol, processed food, vitamin D, and the broader metabolic terrain influencing recurrence risk.Dr. Alschuler is past-President and past-Board member of the American Association of Naturopathic Physicians and a founding board member and Past-President of the Oncology Association of Naturopathic Physicians. She has been an invited speaker to more than 350 scientific/medical conferences, published over 27 peer-reviewed articles, been an investigator on 8 research studies, written 9 chapters for medical textbooks, and has co-authored two books, Definitive Guide to Cancer, now in its 3rd edition, and Definitive Guide to Thriving After Cancer. The American Association of Naturopathic Physicians (AANP) recognized Dr. Alschuler in 2014 as Physician of the Year. She also received an honorary degree from the Canadian College of Naturopathic Medicine and the Joseph Pizzorno Founders award from Bastyr University in the same year. She was honored with the AANP President's award in 2016 and received the Impact award from the National Association of Nutrition Professionals in 2017. In 2020, she received the Sheikh Zayed International Award in Naturopathy. She holds the rank of Professor at Sonoran University and also retains her rank as a Professor of Clinical Medicine at the University of Arizona where she previously served as the Associate Director of the Fellowship in Integrative Medicine at the Andrew Weil Center for Integrative Medicine.For over 10 years, Dr. Alschuler has co-hosted a podcast, Five To Thrive Live! about living more healthfully in the face of cancer and chronic disease. She was the founding Executive Director of TAP Integrative, a nonprofit web-based educational resource for integrative practitioners. Previously, she was the VP of Quality and Education for Emerson Ecologics, a distributor of dietary supplements to healthcare professionals. Prior to that, she was department head of naturopathic medicine at Midwestern Regional Medical Center – Cancer Treatment Centers of America, a JCAHO-certified 95-bed regional medical center. She was also the clinic medical director and botanical medicine chair at Bastyr University. She was on the faculty of Southwest College of Naturopathic Medicine in its early years, helping to establish its botanical medicine curriculum.Outside of her professional commitments, she enjoys early morning walks with her two dogs, relaxing outdoor evenings with her spouse, honing her golf game, and cultivating a deeper sense of purpose and authenticity.https://www.sonoran.edu/faculty/dr-lise-alschuler/https://www.drlise.net/work.html Curranz Supplement: Use code MIKKIPEDIA to get 20% off your first order - go to www.curranz.co.nz  or www.curranz.co.uk to order yours Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwilliden
