In this episode, Melissa breaks down what EDS actually is in practical terms, how it shows up day-to-day, and why so many people go years without a diagnosis. 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-waitlist https://www.chimera-health.com/  Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwilliden

    Mini Mikkipedia - Can Multivitamins Slow Brain Ageing?

    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

    Rethinking Protein and Plant-Based Health with Dr Matt Nagra

    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 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. Using an evidence-based approach, he creates individualised treatment protocols tailored to each patient’s health goals and lifestyle. He has a particular passion for plant-based and vegan nutrition, physical medicine, and chronic disease treatment. With additional training in nutrition, he holds a Plant-Based Nutrition Certification from Cornell University and the T. Colin Campbell Center for Nutrition Studies, where he has also authored multiple articles. His work aims to support individuals in thriving on plant-based diets, while bridging the gap between lifestyle-based interventions and medical care.

    Mini Mikkipedia - Metabolic Memory: Why Your Body Remembers Everything

    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

    Mini. Mikkipedia - What’s a Healthy Body Fat Percentage?

    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
