It is a pleasure to present, Nutrition and Exercise in Obesity Management, for reference and textbook use. The text is an outgrowth of the Obesity Weight Control Track of the 1982 La Crosse Health and Sports Science Symposium, sponsored annually by the La Crosse Exercise Program, University of Wisconsin-La Crosse. With versatile faculty, topics, and attending professionals, the Obesity-Weight Control Track stimulated an effort to produce interdisciplinary resources on obesity. Out of this effort, three books have been compiled and edited. The first book, Evaluation and Treatment of Obesity, introduces an inter disciplinary, practical approach to obesity management. This book, Nutrition and Exercise in Obesity Management, compiles the information specifically related to nutrition and exercise management of obese indi viduals. The third book, Behavioral Management of Obesity, relates be havioral theories to the modification of eating habits and activity patterns. These three books apply the latest information from the fields of medi cine, nutrition, exercise, and psychology to the problem of obesity. The information is intended to guide health professionals in the interdisci plinary management of obesity. In 1983 the Obesity-Weight Control Track focused on controversial issues of theoretical and practical concern. The speakers from this track contributed their expertise to the compilation of two additional books. Thus, Trends and Controversies in Obesity Research and Innovation in Obesity Program Development will complete the series. Consider the five volumes a consolidated, comprehensive reference related to the growing, interdisciplinary field of weight control.
