Mikkipedia is an exploration in all things health, well being, fitness, food and nutrition. I sit down with scientists, doctors, professors, practitioners and people who have a wealth of experience and have a conversation that takes a deep dive into their area of expertise. I love translating science into a language that people understand, so while some of the conversations will be pretty in-depth, you will come away with some practical tips that can be instigated into your everyday life. I hope you enjoy the show!

Mini Mikkipedia - Why the Scale Misleads Women in Midlife
In this Mini Mikkipedia episode, Mikki unpacks why fat loss in midlife never feels as straightforward as it used to — even when your strength is climbing, your shape is changing, and you know you’re doing everything right. She breaks down the hormonal shifts after menopause that make the scale far more chaotic, from cortisol-driven water swings to vasopressin turning you into a temporary camel. Mikki also explores the mindset piece: why new habits feel heavy at the start, why slow progress is still genuine progress, and how to build anchor behaviours that keep you steady when life isn’t. It’s a mix of physiology, reassurance, and practical strategy to help you stay the course without letting one number steal the win.HIGHLIGHTS • Why weight loss naturally slows after menopause • How cortisol + vasopressin create confusing water weight • What “slow but steady” fat loss really looks like • The mindset shift that stops overwhelm and all-or-nothing thinking • Anchor habits to keep you on track through messy weeks

She also covers meds, alcohol, smoking, and what realistic “reversal” of osteopenia looks like in your 50s, 60s and 70s.Episode HighlightsHow much bone density women typically lose after menopauseThe most effective training mix: resistance, impact, and where weighted vests/vibration fitThe surprising role of sleep and stress in bone buildingProtein, calcium, K2, D, magnesium, collagen, creatine & omega-3 for bone healthWhy osteopenia can be improved—and what success really looks like

Mini Mikkipedia - Fat Loss in the Festive Season
The festive season doesn’t have to derail your hard-won progress. In this Mini Micropedia, Mikki unpacks why holiday weight gain (often ~0.45–1.0 kg) tends to stick around and which habits most often tip us off track—overcommitting, grazing instead of meals, early “holiday mode,” and a bit too much booze. She lays out a practical plan: prioritise sleep, ring-fence training (and rack up NEAT—aim ~8,000+ steps), keep protein front and centre, and use calorie cycling with planned indulgences (hello, PSMF structure) to enjoy social events without spiralling. You’ll learn simple boundary-setting scripts, environment hacks to reduce temptation, and mindset shifts—discipline over willpower, self-compassion over perfectionism—to carry you into January feeling calm, in control, and confident.

Mini Mikkipedia - Supplements: Check the Label, Not the Hype
A lot of “natural” stress aids aren’t harmless—because they actually work. In this Mini Mikipedia, Mikki breaks down how popular adaptogens and nutrients interact with your HPA axis (the body’s stress-response command centre) and when that’s a blessing versus a blind spot. You’ll learn what the evidence says for ashwagandha, rhodiola, holy basil, phosphatidylserine, and why liquorice root is uniquely risky. Mikki covers dose ranges used in studies, who should be cautious (thyroid issues, pregnancy/breastfeeding, low cortisol, meds), how to test cortisol properly, and why cycling supplements beats “more is better.” She also revisits the basics that move the needle—sleep, protein-centred meals, training balance, boundaries, and connection—so supplements can supplement a solid plan, not replace it.HighlightsHow HPA axis modulation can help—or hinder—stress recoveryLiquorice root and pseudoaldosteronism: real risks, not theoryPhosphatidylserine blunts cortisol; context and cycling matterRhodiola and holy basil: mixed/early evidence, variable extractsTesting (4-point saliva, timing), interactions, and quality assurance
