"Congratulation on excellent book: informative, readable, broad in its coverage, and very useful to those of us who are not neuroscientists.I particularly appreciated the several concluding chapters that articulated and evaluated the nature, strengths, and shortcomings of models."(Dr Michael Levine, Emeritus Professor of Psychology, Kenyon College, Gambier, USA, November 2102) “This is a very good contribution to the psychiatric literature that will help clinicians, researchers, and neuroscientists in general to understand eating disorders from a biopsychosocial perspective. It gives a very explicit definition of eating disorders as well as treatment options and future overviews.”  (Doody's, 25 May 2012)"Well written and well edited, nicely balanced between academic reviews and integrative theoretical syntheses, the readable chapters will inform readers who lack deep knowledge about biological aspects of eating disorders as well as those who are better informed. Chapters are scholarly without being stuffy, and contributors summarize pertinent studies in structural and functional neuroimaging, neuropsychology, and the neuroscience of body image. For serious eating disorders clinicians as well as academicians, there’s much in this book to study and ponder." - EATING DISORDERS REVIEW “There has been an important paradigm shift in thinking about eating disorders in that the brain is receiving  more  attention.  The Academy of Eating Disorders has published a position paper placing the brain more centrally within these highly complex multifaceted disorders.  This book is an important addition to the literature: the authors are all expert communicators and are able to make the topic simple, enjoyable  and easy to understand.”  - Janet Treasure, Professor of Psychiatry, Guy’s, King’s & St Thomas’ Medical School, London, UK
