What to Eat When

Internist and anesthesiologist Roizen, author of nine best-selling books (e.g., You: The Owner's Manual; RealAge), teams up with preventive medicine specialist Michael Crupain and health and science writer Ted Spiker to present a 31-day eating plan that complements our circadian rhythms, the 24-hour fluctuations in our bodies tied to the sleep-wake cycle. They suggest that eating in a way that complements our internal rhythms helps our bodies utilize and metabolize food most effectively. In addition to outlining a meal plan and discussing the science behind it, the authors offer a series of "choose your own adventure" chapters that introduce a different emotion, health condition, or situation and what foods best address them. This arrangement makes for a practical guide that can be consulted time and again, as individuals face the challenges of everyday life. If there's one weakness, it's the surprising absence of recipes to support the prescribed "When Way" lifestyle. VERDICT This well-organized, accessible guide to healthful eating by two well-known medical consultants, both affiliated with the Dr. Oz Show, is sure to be widely popular with health-conscious readers.--Crystal Renfro, Kennesaw State Univ., Marietta, GA
