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.

    Mini Mikkipedia - Breakfast and Fat Loss: What the Evidence Really Says

    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 Learn Why 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

    Mini Mikkipedia - Aspartame, Insulin & Weight Loss: What Science Shows

    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. Mikki also unpacks concerns around methanol and amino acid breakdown products, and explains why observational studies often drive misleading headlines. If you enjoy a diet drink and worry it’s sabotaging your fat loss or metabolic health, this episode offers clarity grounded in human clinical data—not fear-based speculation. Highlights Why aspartame does not trigger insulin spikes in human trialsWhat the research shows about hunger, appetite hormones, and calorie intakeThe difference between observational studies and randomized controlled trialsMethanol, phenylalanine, and aspartic acid: dose, context, and perspectiveWhether diet drinks interfere with weight loss or metabolic flexibility 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 - Binge Eating: Why “Just Eat Less” Backfires

    On this episode of Mikkipedia, Mikki tackles binge eating behaviours and why the traditional “just eat less” approach often fails. 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. Highlights Binge 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/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 - The Most Dangerous Phase of Fat Loss

    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 Covered What “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/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
