The series volumes are not the outcome of a symposium. Rather, each editor has the potential to examine a chosen area with a broad perspective, both in subject matter as well as in the choice of chapter authors. The editors, whose trainings are both research- and practice-oriented, have the opportunity to develop a primary objective for their book, define the scope and focus, and then invite the leading authorities to be part of their initiative. The authors are encouraged to provide an overview of the field, discuss their own research, and relate the research findings to potential human health consequences. Because each book is developed de novo, the chapters are coordinated so that the resulting volume imparts greater knowledge than the sum of the information contained in the individual chapters. The Management of Eating Disorders and Obesity, Second Edition, edited by David J. Goldstein clearly exemplifies the goals of the Nutrition and Health Series. The first edition was widely acclaimed for its emphasis on data-driven clinical applications of the newest scientific discoveries in the areas of bulimia, anorexia, binge eating, and the complex, chronic disease of obesity. Dr. Goldstein, who is an internationally recognized leader in the fields of obesity and eating-disorder research, has enhanced the contents of the first edition even further with the addition of three timely, new chapters. The first two new chapters cover the internet and its value in the education and potential treatment of eating disorders in one chapter, and the use of the internet in education and treatment of obesity in a second chapter. The third critically important chapter reviews the role of hunger and satiety in obesity treatment. All of the original chapter authors, the most authoritative leaders in obesity and eating-disorder research, have updated the contents and have included recent references, figures, and graphs. Thus, Dr. Goldstein has devel- oped a second edition that is destined to be the benchmark in the field because of its extensive, in-depth chapters covering the most important aspects of eating disorders and obesity, with emphases on human physiology, treatment, and disease prevention. The book chapters are logically organized to provide the reader with a basic understanding of the clinical conditions of bulimia nervosa, anorexia nervosa, and obesity in the first chapter of each of the book’s three major sections. Each section also v Goldstein_2nd_FM_Final 5 11/2/04, 2:46 PM vi Series Editor’s Introduction contains chapters that address treatment options as well as prevention strategies. This logical sequence of chapters provides the latest information on the current standards of practice for clinicians, related health professionals including the dietitian, nurse, pharma- cist, physical therapist, behaviorist, psychologist, and others involved in the team effort required for successful treatments. This comprehensive volume also has great value for academicians involved in the education of graduate students and postdoctoral fellows, medical students, and allied health professionals who plan to interact with patients with eating disorders including obesity. Cutting-edge discussions of the roles of growth factors, hormones, cellular and nuclear receptors and their ligands, gene promoters, adipose tissue, and all of the cells directly involved in fat metabolism are included in well-organized chapters that put the molecular aspects into clinical perspective. Of great importance, the editor and authors have provided chapters that balance the most technical information with discussions of its importance for clients and patients as well as graduate and medical students, health professionals, and academicians. Separate chapters in the three sections include specific, detailed information on the counseling of patients with bulimia and the pharmacological treatment of bulimia. There is a unique chapter that looks at the role of nutrition and dietary factors in the prevention of eating disorders. The anorexia section includes four chapters devoted to basic infor- mation, treatment strategies, detailed information on pharmacological therapies, and the new chapter on internet resources. The third section is the largest and contains three chapters on general aspects of obesity including the etiologies of obesity, medical consequences of obesity, as well as benefits of weight loss and a very practical chapter on binge eating in the obese. Thirteen chapters are devoted to the treatment of obesity. These include an overview of current treatment options as well as a discussion of future treatments that are already in development. Critical to any weight-reduction program is exercise, and there is a comprehensive chapter on the role of physical activity, exercise, and nutrition in weight control. The importance of a team approach to the treatment of obesity as a chronic disease is extensively discussed in the chapter on lifestyle modification in the treatment of obesity. Specific treatment modalities are reviewed in separate chapters on very low- calorie diets, pharmacotherapies, combination therapies, the potential for genetic inter- ventions, the new chapter on hunger and satiety, and surgical interventions that are discussed in detail, including drawings that depict the specific types of surgeries currently available. Each of these chapters presents an objective evaluation of the treatment and identifies the positives and negatives that have been seen during clinical studies, as well as cumulative data derived from clinical practice. The final four chapters in the obesity treatment section examine the clinical experi- ences in a comprehensive weight-management program, the importance and value of a multidisciplinary team in the management of obesity, the potential for the internet to help in obesity treatment, and a most candid chapter on the barriers to obesity treatment. The final book chapter reviews the most medically relevant alternative to treatment–preven- tion of obesity—and examines the signs that could alert the health professional to the potential for the development of obesity, as well as outlines the steps to take to help prevent the overweight patient from moving to frank obesity. Goldstein_2nd_FM_Final 6 11/2/04, 2:46 PM Series Editor’s Introduction vii There is a clear, data-driven message throughout the obesity section of the volume that obesity is a chronic disease. As with hypertension that can be controlled by drug therapy, so with obesity—therapy cannot stop once a particular weight-loss goal is reached. Like hypertension that reappears without chronic treatment, obesity can easily reappear if not treated as a chronic disease. Detailed tables and figures assist the reader in comprehending the complexities of the disturbances in eating behaviors. Modulators of eating responses that are covered in this section include adrenergic receptors, cholecystokinin, γ-aminobutyric acid, histamine and serotonin receptors, insulin, leptin, neuropeptide Y, galanin, ghrelin, growth hormone, as well as substances that can be consumed in diet and/or supplements such as caffeine, ephedrine, aspirin and lithium, olestra, and yohimbine. Novel treatment options that are of great interest to clients and patients are included in several chapters that review more than 50 therapeutic agents. In-depth descriptions of behavioral modification programs, mental states, evaluation tools for documentation of patient eating habits, and many other valuable treatment aids are included in numerous chapters. Thus, The Management of Eating Disorders and Obesity, Second Edition is focused on answering questions commonly asked by clients and patients about why some diets do not work and why some “professional” sources advocate certain products that are available over the counter but may not “work.” The overriding goal of this volume is to provide the health professional with the balanced documentation to assure the client/patient that eating disorders and obesity are complex states that transcend the simplistic view of just losing a few pounds. Hallmarks of all chapters include bulleted key points at the beginning of each chapter as well as a detailed table of contents; complete definitions of terms with the abbrevia- tions fully defined for the reader and consistent use of terms between chapters. There are numerous relevant tables, graphs, and figures as well as up-to-date references; all chapters include a conclusion section that provides the highlights of major findings. The Management of Eating Disorders and Obesity, Second Edition contains a highly annotated index and within chapters, readers are referred to relevant information in other chapters. This important text provides practical, data-driven resources based on the totality of the evidence to help the reader understand the basics, treatments, and preventive strategies that are involved in bulimia, anorexia, and obesity. The overarching goal of the editor is to provide fully referenced information to health professionals so they may have a balanced perspective on the value of various treatment options that are available today as well as in the foreseeable future. In conclusion, The Management of Eating Disorders and Obesity, Second Edition, edited by David J. Goldstein provides health professionals in many areas of research and practice with the most up-to-date, well-referenced and easy-to-understand volume on the importance of identifying and treating those already suffering from bulimia, anorexia, and/or obesity as well as providing strategies to prevent the development of these chronic, serious diseases. This volume will serve the reader as the most authoritative resource in the field to date and is a very welcome addition to the Nutrition and Health Series Adrianne Bendich, PhD, FACN Series Editor Goldstein_2nd_FM_Final 7 11/2/04, 2:46 PM Foreword The 6 years since the publication of the first edition of The Management of Eating Disorders and Obesity has seen a sea change in our view of obesity. At the time of the first edition, obesity was still viewed as a fairly simple problem, with unfortunate, but not necessarily dire, consequences. Since that time, the importance of obesity has broken into our general awareness and into the medical literature in particular. The enormous increase in obesity, to the extent that two-thirds of Americans are overweight or obese, is now termed an “epidemic.” This epidemic is destined to become even more severe as the huge increase in childhood obesity has its impact on obesity in later life. The serious health consequences of obesity are being increasingly recognized and Syndrome X has become a household word. This situation in the treatment of obesity is a major reason for the consternation caused by the removal of fenfluramine from the market just as the first edition of this volume was published, because fenfluramine was the most effective pharmacological agent for the treatment of obesity yet employed and was a sound basis for medical treatment of the disorder. No other medication for obesity has yet taken its place. In the face of the uncontrollable increase in obesity, the public is turning increas- ingly to popular fads. The explosion of interest in the Atkins Diet, and “low carbs” illustrates a near hysteria on the part of the general public. Forty million Americans are said to be currently following the not entirely benign Atkins Diet. In these frantic days, an important task of the practitioner is to forestall the more needless, and even harmful, results of the hysteria. As befits an epidemic, public health efforts are being introduced in increasing measure to schools, communities, and in public communication, as through the internet. The focus of these methods is on the favorable changes in lifestyle that may help to prevent obesity from developing, control it when it develops, and, in some cases, reduce it. As outlined in Food Fight by Brownell and Horgen (1), the beginning of this effort is to think differ- ently about foods, not as “good” or “bad,” but in total calories of food intake. Next, public health and medical efforts should be combined to increase physical activity and to establish simple but sound eating habits that include smaller portion sizes. These activities had not been ones that, until now, the practitioner would have been able to pursue under the circumstances prevailing because they require services that had not been reimbursed. Awareness of the epidemic nature of obesity has led to the salutary conse- quence of the US Food and Drug Administration labeling obesity “a disease.” This long- delayed action has important consequences. It makes it possible for the treatment of obesity to be reimbursed. For the first time, practitioners may be able to devote the time necessary for the successful treatment of obesity. Furthering at the individual level the efforts made at the public health level means that the practitioner can, for the first time, be able to advise patients on favorable lifestyle changes. ix Goldstein_2nd_FM_Final 9 11/2/04, 2:46 PM x Foreword The eating disorders, in contrast to obesity, have been the subject of only modest change since the first edition of this volume. The greatest improvement has been in the management of bulimia nervosa. Intensive research has produced improvements in both the pharmacological and behavioral treatments of bulimia nervosa, and in their combi- nation. The treatment of bulimia nervosa is still largely the province of specialists devoted to treatment of the disorder. But there is a critical role for the clinician in diag- nosing it and referring patients for treatment. The earlier the treatment begins, the better its results, both in the short term and in the long term. Patients with bulimia nervosa should not be allowed to suffer without the effective help that is now available. Binge-eating disorder has received increasing attention in recent years and it is now recognized as a widespread problem. A number of studies of pharmacological and psy- chological treatment have shown that these agents improve the symptoms of binge eating. This improvement, however, has not produced weight loss and the usefulness of this diagnosis has been questioned (2). The problem of anorexia nervosa is the most challenging among the eating disorders. Despite continuing research, little progress in treatment has been made. The most effec- tive treatment for anorexia nervosa may well be Russell’s (3) decades-old program of family therapy for young anorectics. As with bulimia nervosa, the practitioner can pro- vide a valuable service in identifying patients with anorexia nervosa and carrying out the difficult task of getting them into treatment. The current status of the disorder is well described in the four chapters devoted to it. Albert J.
