Distinguishing his approach from diet and fitness books, physiologist Greene (Make the Connection) prescribes lifestyle changes to get "back in shape, physically and emotionally." Greene, Oprah Winfrey's personal assistant and a frequent guest on her show and contributor to O
magazine, first encourages readers to change thought and behavior patterns, by being honest with themselves, committing to change and undertaking such deceptively simple measures as hiding their remote controls and walking instead of driving. From there he prescribes signing a contract with oneself, keeping a "happiness journal" and, of course, specific exercise, stretching and dietary practices. Readers looking for a jump-start to making big changes will find this gung-ho guide manageable. (Jan. 8)
