Announcing: Dr. Casey Means’ new book, Good Energy

Levels Co-Founder's new book—Good Energy: The Surprising Connection Between Metabolism and Limitless Health—releases May 14; available for pre-order today



We are thrilled to announce that Levels Co-Founder, Dr. Casey Means, is publishing her first book, Good Energy, on May 14! Pre-order your copy here!

The book chronicles what inspired Casey to leave her career as a surgeon, co-found Levels, and devote her life to the metabolic health crisis. It’s a clear, step-by-step action plan for optimal metabolic health and glucose control (with learnings from the Levels dataset!).

Readers of Good Energy will get:

  • The 13 key blood tests everyone should get – and the optimal ranges to target (that are often very different from official recommendations).
  • The 6 principles of good energy eating that apply to any dietary pattern or philosophy, from vegan to carnivore.
  • Quizzes to take stock of where there is the most room for optimization of good energy in your own diet and lifestyle.
  • 25 good energy habits for metabolic health, and exactly how to implement them in your life.
  • 30 good energy recipes with details on how they support metabolic function.
  • The wearables, tools, and at-home testing that you can use to understand your body and tailor lifestyle and dietary choices.
  • Detailed lists of good energy foods and bad energy foods and how to shop and source for healthy food.
  • How to reset your biological clock, which includes a focus on sleep, meal timing, and light exposure.
  • Steps to “replenish what modernity took away”– including exercise, temperature exposure, and reducing environmental toxins.
  • Lists of non-toxic home care and personal care products and tools that support good energy.
  • The ultimate guide to blood sugar stabilization strategies based on research literature and the Levels dataset.
  • 15 steps to heal the mindsets and limiting beliefs that undermine optimal metabolism.

The ultimate message is simple: Metabolic health = GOOD ENERGY = The simple answer to achieving incredible health, for ourselves, our children, our parents, and the planet. Be the first to get it by pre-ordering a copy today.

“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 with many other chronic illnesses — is 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.”
Terry Wahls, MD, author of The Wahls Protocol – A Radical New Way to Treat All Chronic Autoimmune Conditions Using Paleo Principles
