Many people occasionally suffer from a negative body self-image but, for an increasing number of people, this can turn into a more serious preoccupation.

Body image problems can cause significant distress and can lead to further problems such as anxiety, eating disorders and social phobia. It has long been recognised that negative body image problems are a factor in the onset and maintenance of many eating disorders. However, they can be successfully treated with cognitive behavioral therapy techniques like those in this book.
