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!

Brandon's back! The Truth About Exercise and Energy Burn

Brandon offers his take on how constrained energy expenditure has been misrepresented to suggest that exercise is ineffective for weight loss, and he brings both data and coaching insights to the conversation.They also explore the concept of metabolic adaptation, sustainable metabolic scope, and what the research really says about the relationship between physical activity and body composition over time. This conversation is essential listening for anyone navigating the complexities of energy balance, fat loss, and exercise science.Brandon DaCruz at his website https://www.brandondacruzfit.com/, and on Instagram @brandondacruz_Chasing Clarity https://podcasts.apple.com/us/podcast/lyle-mcdonald-challenging-the-constrained-energy/id1619611966?i=1000709417044Brandon DaCruz is an online nutrition and physique coach and sports nutritionist.

Mini Mikkipedia - Mastering Cognitive Restraint: The Skill That Transforms Your Diet
Sign up to Mondays Matter Xmas Edition https://www.mikkiwilliden.com/mondays-matterIn this Mini Mikkipedia Monday, I’m diving into the concept of cognitive restraint — the intentional, often skill-based ability to say “no thanks” to food when it doesn’t align with your goals. This isn’t about deprivation or dieting harder, but about building an empowering skill that helps you align your actions with your intentions. I share how cognitive restraint is developed over time (it’s not just something you’re born with), reflect on my own experience with overeating, and offer a practical roadmap of mindset shifts and tools to make restraint feel easier and more automatic. Whether you’re on a fat loss journey or just trying to regain control over your eating habits, this episode offers strategies you can start using today.Highlights:Why cognitive restraint is a skill, not willpowerThe reframe that changes “restriction” into “empowerment”Practical strategies to build restraint (meal planning, mindfulness, visualisation)How your environment and daily habits impact your ability to follow throughThe power of identity and self-talk in long-term dietary success
