About The Cover

Although a nursery rhyme would have us believe otherwise, the regulation of body weight is a complex process involving environmental, physiological, and behavioral factors (depicted whimsically around a feasting Mr. and Mrs. Jack Spratt). These factors and advances in preventing and treating disorders of weight regulation are discussed in the special section beginning on 1363. Hidden in the illustration are the names of 13 proteins associated with weight regulation (answers on 1363). [Illustration: David Galchutt]
