Change Your Environments

Eric Berg, D.C., (The Knowledge Doc®) is the world's most-watched health educator, with 40.8 million subscribers on his YouTube channels and 110 million monthly views on social media. For more than 36 years he's been focused on one question: why does chronic disease develop, and what has to change to reverse it? His answer: it's not genetics, it's environment — and most of it is fixable. Dr. Berg is the founder of the Chronic Disease Project and the WellnessMAP research platform.

Praise for Change Your Environments“If you are like most people, you are overwhelmed with the full-time, even around-the-clock, job that just living life and staying healthy has become. Microplastics, pesticides, mercury, don't eat this or that, ultra-processed foods . . . What should you believe and how can you distill it down to truly manageable strategies before you throw your hands up in frustration? In Change Your Environments, Dr. Berg brings his signature straight-talking style and provides a virtual GPS for navigating all the complexities and nuances of these issues, providing clear, straightforward advice that even your teenager can manage.”—William Davis, MD, #1 New York Times bestselling author of Wheat Belly, Super Gut, andSuper Body“In Change Your Environments, Dr. Eric Berg offers a practical and thought-provoking framework for understanding how our daily surroundings shape our health. The book reminds us that many of the most powerful health interventions are not complicated. Whether it is spending more time outdoors, improving sleep, reducing environmental stressors, or redesigning daily habits, Dr. Berg provides a roadmap for creating conditions in which health can flourish. It is a timely reminder that sometimes the path to better health begins not with adding something new, but with reconnecting to what has been there all along.”—Roger Seheult, MD"Some health care experts are good at theory and have a great knowledge of the literature of health and medicine, but what they know is through the eyes and experience of others. Dr Berg is no such doctor. He gets down into the nitty gritty of food and environmental control, and the living dirt on his farms to really know what he is talking about because he has lived it and is doing it, and then as a master teacher, communicating these principles, so others can learn them and live them. In this book, you will understand the essential tools to live healthy and long. What better gift could an author give?”—David I. Minkoff, MD"As a heart surgeon, I see every day how the environments we live in drive the metabolic disease that lands patients on my operating table. Dr. Eric Berg’s Change Your Environments gives you the missing map: nine key environments, a simple audit to identify your highest-leverage fixes, and the insight that improving one upstream environment creates powerful cascading improvements in the others. This is the practical redesign tool that finally makes sustainable metabolic health achievable — without needing more willpower.”—Philip Ovadia, MD, author of Stay Off My Kitchen Table“In my work helping patients reverse diabetes, I see firsthand that chronic metabolic issues aren't a failure of willpower. Your hormones are simply reacting to a chaotic modern lifestyle. In Change Your Environments, Dr. Berg skips useless band-aids like calorie counting and focuses entirely on fixing the spaces where we live and work. By changing the simple inputs around you, you let your body naturally reset your blood sugar, sleep, and weight. It’s a practical, real-world guide that gets straight to the root cause.”—Dr. Roshani Sanghani, endocrinologist and author of Turn Around Diabetes: A Step-by-Step Guide"For thirty years I watched patients arrive with a drawer full of single answers: one pill, one diet, one exercise that was going to fix everything. It almost never did, because health is not a single problem to be solved. It is many connected systems, and you cannot repair one while the others keep doing damage. This book is the first I have seen that addresses the whole picture and provides an actionable, easy-to-follow map. Specific steps, no generalities. It shows you where your own weak point is and exactly what to do about it. A must-read."—Dr. Dimitris Tsoukalas, MD, PhD, founder of Metabolomic Medicine® Clinics“In Change Your Environments, Dr. Berg delivers a powerful, practical reframing of health: lasting change is not about forcing more discipline, but redesigning the surroundings that shape our biology and behavior every day. This book gives readers a clear map for transforming the hidden environments behind eating, sleep, movement, stress, focus, social connection, and long-term health. It is an empowering guide for anyone frustrated by willpower alone—and a smarter path to making better choices automatic. ”—Dr. Rob Cywes, MD“Change Your Environments is packed with practical, actionable advice that can genuinely improve people's lives. Even after more than fifteen years of nutrition research, I found many valuable insights that I've already put into practice myself. I highly recommend this book.”— Chris Knobbe, MD, founder of AncestralHealth.ai
