Obesity is a serious health issue and is a key discussion and research area in many disciplines from the social sciences and physical education to the health sciences. The Encyclopedia of Obesity is a comprehensive set containing nearly 500 entries that addresses the broad scope of the obesity epidemic, from molecular and genetic causes to the treatment of this disease at a large scale, public policy level. The editors have chosen topics that capture the current climate of obesity research, while still addressing and defining the core concepts related to this disease. Additionally, the majority of entries have been provided by experts from the medical and scientific research community. In many cases, entries are written by pioneering or premiere researchers in the topic at hand. This two-volume Encyclopedia provides a catalogue of entries from a variety of expert contributors from a vast array of disciplines, including molecular biology, psychology, medicine, public health and policy, food science, environmental health, pharmaceuticals, and many others to summarize pertinent topics in obesity, and related health conditions. Scholars, educators, researchers, physicians, and the general public will be able to access this resource for current, factual details on topics related to this growing epidemic.

It will for the first time, allow scholars who are conducting research to access hundreds of topics related to obesity, all within a single text. The convenient organization of this text will assist readers most when they have a specific term they wish to investigate, however, for readers who do not know the specific search term, each article is cross-referenced with other article headings.
