 ”Part memoir, part manifesto, there isn’t another voice in the zeitgeist as cogent, urgent, and powerful as Casey’s. The gauntlet’s been thrown down — consider yourself warned.”

—Robert Lustig, MD, MSL, emeritus professor, UCSF, author of Metabolical

Praise for Good Energy

  • “Fitness and healthy food should be at the center of how we think about preventing and reversing disease and obesity — but they aren't. Good Energy explains why this is the case and provides readers tactical tips to take their power back. Calley and Casey Means are bold siblings on a mission who communicate timeless and accessible metabolic principles that anyone can implement." 

    — Jillian Michaels
    Fitness and nutrition expert, author, and entrepreneur

  • “Good Energy is a powerful vision for a brighter future - for both people and the planet. Dr. Means presents an empowering action plan for health of the mind, body, and spirit that everyone can benefit from.”

    — Jay Shetty, #1 New York Times bestselling author and host of the On Purpose podcast

  • “A tour de force on how metabolism underpins most major diseases and what we can do to feel better and live longer. Everyone will benefit from reading Good Energy.”

    — Mark Hyman, MD
    15x NYT bestselling author, senior advisor for Cleveland Clinic for Functional Medicine, founder of The UltraWellness Center

  • “The final document I signed when I retired in 2011 was entitled ’Total Force Fitness,’ a directive focused on improving the comprehensive fitness of our over two million men and women who serve. Its objective was to improve and sustain the mental, moral, physical and spiritual fitness of every Soldier, Sailor, Airman and Marine, which I felt was a National Security imperative. Dr. Casey Means has now provided the prescription for this in 'Good Energy.' For too long we have created a "health care" system that is really a “sick care” system. Its outcomes are too often marginal in improving our overall and long term health. Improving the metabolic health of Americans is an urgent national security priority. We are in a health crisis in our military and our nation. The path prescribed herein optimizes our metabolic habits while modernizing our health system to fix the root causes. Brilliant, timely, and remarkably impactful. Read this book. Tell your friends.”

    — Mike Mullen, Admiral USN (Ret.), 17th Chairman, Joint Chiefs of Staff

  • “Dr. Casey Means brilliantly illuminates the pivotal role of disturbed metabolism in setting the stage for chronic degenerative diseases, and offers a comprehensive roadmap for enhancing and maintaining metabolic health. This book is a must-read for healthcare professionals and individuals alike, seeking to understand and improve their overall health. With her insightful and loving guidance, Dr. Means is handing us the keys to the kingdom, prolonging our healthspan, making this book a game-changing, invaluable resource in our journey towards lasting wellness.”

    — David Perlmutter, MD, FACN
    Author of the #1 New York Times bestsellers, Grain Brain and Drop Acid

  • "Casey's experience as a doctor and her deep passion for helping people understand their health shines through in her book. Get ready for the best deep dive and needed explanations into the diseases that plague us all today, along with what to do to heal.”

    — Jessie Inchauspe, biochemist, New York Times bestselling author and founder of the Glucose Goddess movement

  • “Dr. Casey Means slid down the rabbit hole — malfunctioning mitochondria, dinosaur doctors, fake food, pharma failure, health harms, and political payoffs. Good Energy tells the story of a medical system run amuck, and yet how you can be the good you want to see in the world.”

    — Robert Lustig, MD, MSL, Professor emeritus of Pediatrics, UCSF, author of Metabolical

  • "Good Energy should be required reading for every medical student and healthcare practitioner. As a system and as individuals, we must adopt a metabolic, mitochondria-focused lens for health and vitality. Autoimmunity — along many other chronic illnesses —  are closely tied to metabolic dysfunction and insulin resistance.  Foundational to better energy and health outcomes  is getting metabolic health and blood sugar under control. Dr. Means shows readers how." 

    — Dr. Terry Wahls, MD
    Author of The Wahls Protocol - A Radical New Way to Treat All Chronic Autoimmune Conditions Using Paleo Principles

  • “Good Energy is a life-changing book full of accessible science and practical strategies for metabolically healthy living and blood sugar control. Dr. Means's book is unique in connecting the dots on diverse aspects of health from the cellular level to the spiritual, and from soil biodiversity to healthcare incentives. Readers will be inspired and empowered by her hopeful message on the key strategies and tools for how to thrive. People at all phases of life benefit from a metabolic framework to feel their best, and Casey paints a clear case for why, and how to achieve it."

    — Sara Gottfried, MD
    New York Times bestselling author, and Director of the Precision Medicine Program at the Marcus Institute of Integrative Health at Jefferson Health

  • “In Good Energy, Dr. Means makes a bold case for why food — and particularly regenerative agriculture — must be at the very center of healthcare. She has emerged as one of the strongest physician voices teaching doctors and patients that we will never achieve optimal human health without optimal soil health and biodiversity— a message that the healthcare system would be wise to pay attention to.  Dr. Means makes it clear that we can't drug our way out of a broken food system. Good Energy will inspire you to care about how the soil your food is grown in affects your overall health.”

    — Will Harris
    Regenerative agriculture leader and owner of White Oak Pastures

  • “An empowering book which argues we have much more control over our health than we’re led to believe.” 

    — Max Lugavere
    Health and science journalist, filmmaker, and bestselling author of Genius Foods

  • “In Good Energy, Casey and Calley Means powerfully explain how we can use metabolic health tools and strategies to support our own health and that of our children and families.”

    — Kelly Leveque
    Celebrity nutritionist, author, and entrepreneur

  • "In Good Energy, Dr. Means challenges the conventional dogma of healthcare and presents a compelling case for a metabolic-focused approach to longevity, health, and weight management. Good Energy is full of actionable steps to be mentally and physically strong, and revitalize your life.”

    — Dr. Gabrielle Lyon
    Author of the New York Times bestseller Forever Strong

Good Energy offers a new, cutting-edge understanding of the true cause of illness that until now has remained hidden. It will help you optimize your ability to live well and stay well at every age.

ABOUT THE BOOK

What if depression, anxiety, infertility, insomnia, heart disease, erectile dysfunction, type 2 diabetes, Alzheimer’s dementia, cancer and many other health conditions that torture and shorten our lives actually have the same root cause?

The truth is, they do. And our ability to prevent and reverse these conditions - and feel incredible NOW - is under our control and simpler than we think. The key is our metabolic function: the way we make energy in our cells and bodies. The ability to make GOOD ENERGY in our bodies is the most important and least understood factor in our overall health, and the biggest blindspot in healthcare.
