This clip from the MetFix Foundations Seminar explains how mitochondria—your cells’ tiny power plants—are central to energy production, metabolic flexibility, and long-term health. Pete Shaw covers how these organelles convert carbohydrates, fats, and proteins into ATP, the body’s primary energy currency, and how healthy mitochondria enable you to switch efficiently between fuel sources. When mitochondrial function is compromised, the body relies more on carbohydrate-dependent anaerobic pathways, which can contribute to chronic disease.

The talk also explores the major energy systems—glycolysis, gluconeogenesis, beta-oxidation, ketogenesis, and the phosphocreatine pathway—using a fire analogy to show how different fuels burn at different speeds. The takeaway: supporting mitochondrial health through nutrient-dense foods, balanced macronutrients, and smart dietary choices is key to preventing disease, maintaining energy efficiency, and sustaining health.
