Good Energy by Casey Means, MD

Good Energy by Dr. Casey Means is built around one big idea: our health and longevity depend on how efficiently our cells make and use energy. When our mitochondria are working well, we have “Good Energy”—showing up as vitality, mental clarity, stable moods, and resilience. But when modern life (processed food, poor sleep, chronic stress, toxins, screen time) disrupts that system, we slip into “Bad Energy,” which Dr. Means links to many of today’s chronic illnesses—from diabetes and heart disease to anxiety and infertility.
The book mixes science, stories, and practical steps. Means critiques our healthcare system for treating symptoms instead of addressing root metabolic dysfunction, then offers readers a blueprint for taking back control. She outlines a four-week plan that emphasizes real food, circadian rhythm alignment, movement, stress management, and mindful living. Recipes and daily tools make the ideas feel doable, while the “Good vs. Bad Energy” framework helps readers connect the dots between everyday choices and long-term health. Ultimately, Good Energy is both a call to action and a hopeful guide for creating a healthier future by focusing on cellular energy as the foundation of well-being.
