At last, here's a book that synthesizes the increasingly popular CR (Calorie Restriction) diet for the layperson. CR is not a diet primarily about weight loss, although readers will lose weight. CR is about eating highly nutritious foods to extend your healthy years. Here's the concept: eat fewer calories and choose foods more carefully. This will reallocate how your metabolism uses its resources to convert food into energy; in other words, what goes in will be used more efficiently. You will feel better and function better—and the big bonus: the CR diet slows aging. CR lengthens the periods of youth and middle age and substantially reduces the risk of virtually all the diseases of aging. Brian Delaney and Lisa Walford, two longtime CR practitioners, will take you on a handheld stroll through the process, including an introduction to CR, how to do it, some of the key issues in the current dialogue, and the skinny on superfoods.
