In this ground-breaking guide, New York Times bestselling author and leading natural health practitioner Dr Joseph Mercola explains how nearly all disease - including cancer - is caused by defective metabolic processes. This astonishing truth could revolutionize our understanding of other diseases and show us a radical new path to optimal health.

Dr Mercola breaks down complicated science into easily digestible facts to help you understand how a damaged metabolism affects your health, and how to begin healing it. Using this book, you'll come to understand how:

- your metabolism goes haywire when dysfunction takes place in the mitochondria, the body's natural powerhouse
- a cyclical ketogenic diet - low in carbohydrates and high in healthy fats - is the way to optimize the biochemical processes that suppress disease and support healing
- following a ketogenic diet can boost brain power, increase energy, assist weight loss and bring about many more health benefits

This simple but powerful diet manifesto can help not only to treat and prevent serious illness, but will also empower you to take control of your health simply by giving your body the proper fuel it needs for healing and thriving.
