In The Wahls Protocol, pioneering medical researcher Dr. Terry Wahls offered a paradigm-shifting approach to treating autoimmune disease, dramatically transforming the lives of readers. Now, Dr. Wahls presents clinical evidence and a completely updated full spectrum health program that can prevent or address all chronic disease. As Dr. Wahls illustrates, the root of chronic disease is the body's underlying cellular dysfunction that erodes its ability to perform optimally over time. The Wahls Spectrum is designed to restore cellular health, stabilize blood sugar, contain inflammation, strengthen the microbiome, and create a ripple effect of repair and the restoration of vitality, energy, and function. This book provides a 5-stage, customised program, along with essential guidance including: the dietary strategies most proven to prevent or manage chronic disease. Interventions to address warning signs of impending disease, like headaches, mood imbalance, low energy, and test results that are borderline or only slightly abnormal. The benefits of a temporary elimination diet to help calm inflammation and understand persistent symptoms. The power of ketosis for managing severe metabolic or neuropsychiatric illness, including treatment-resistant mental health issues. When to introduce foods back in your diet as your health changes or improves. How to safeguard your health, even if you have a family history of genetic disease or have a genetic disease yourself. What to know before trying intermittent fasting, a very low-fat diet, or the carnivore diet. Whether readers seek prevention, early intervention, or improvement of digestive, metabolic, neurodegenerative, neuropsychiatric, or autoimmune disease, they will find effective strategies and inspiration. Dynamic and flexible, The Wahls Spectrum will help you create powerful new habits for lasting results, and live a happier, healthier, longer life.
