"From the author of Identically Different comes a new look at nutritional health, showing us that breakthrough research on microbiomes--the microbes in our stomachs--could hold the key to healthy, balanced diets,"--Novelist. Most diet plans prove to be only short-term solutions, and few strategies work for everyone. Spector believes the key to health and weight loss isn't which foods we eat-- it's the essential digestive microbes already inside us. He explores the hidden world of the microbiome, and demystifies the common misconceptions about fat, calories, vitamins, and nutrients. Only by understanding what makes our own personal microbes tick and interact can we overcome the confusion of modern nutrition, allowing us to regain natural balance in our bodies.
