Mikkipedia

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

2026/05/17

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

Mikkipedia ·

2026/05/03

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

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

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.
