Even though this is not a long book, Sarah Whittle packs in a ton of information about fasting and the safe way to go about starting a diet and sticking to it. There was a lot in here that I learned that I hadn't know about before. This is a great book for anyone interested in detoxifying their body, exercising, and getting back on a healthy track with their diet. “Fasting and Weight Loss - The How to Guide” is an easy way to improve your lifestyle and eliminate complications that come with today’s fast-food unhealthiness.
