Caulfield takes us quickly through the research and bafflegab about diet, fitness and genetics to give a few key messages about healthy living. In the book he talks to many experts and cites many studies but he also puts theory to practice by taking his own advice which adds some fun to the story. Caulfield is supportive of evidence based research and very critical of most alternative therapies and medicine but he also slams the pharmaceutical industry and how it has co-opted parts of the medical establishment. If you are interested in health and fitness this is a thought provoking and entertaining read.
