Good Energy books by Dr. Casey Means

Overview

In Good Energy books: The Surprising Connection Between Metabolism and Limitless Health, Dr. Casey Means, a physician and co-founder of Levels, challenges everything you think you know about health. This book isn’t just about metabolism—it’s about energy, vitality, and the cellular foundations of optimal living.

Instead of narrowly focusing on calories or macros, Dr. Means expands the concept of energy to include mitochondrial health, inflammation, and the connection between lifestyle and chronic disease. This is functional medicine with a data-driven, empowering twist.

Key Takeaways

• Metabolism = Health: Your metabolic health isn’t just about weight—it’s a root marker of chronic disease and mental clarity.
• Cellular Energy Production: The body’s ability to convert food into usable energy efficiently is the core of limitless health.
• Mitochondrial Function: Damaged mitochondria = fatigue, brain fog, and inflammation.
• Lifestyle > Medication: Sleep, movement, light exposure, and diet can heal what pills often cannot.
• Glucose Awareness: The future of personalized health includes real-time glucose and biomarker tracking.
