Obesity is a medical condition in which the body is characterized by excessive amounts of fat. The leading cause of obesity is consuming a higher number of calories than can be utilized or burnt through the routine activities of the body. Eating disorders include several psychological conditions characterized by abnormal eating behaviors that negatively impact a person’s physical and mental health. Some of the common eating disorders are binge eating disorder, anorexia nervosa, pica disorder, and avoidant/restrictive food intake disorder. There are two types of eating disorders associated with obesity, including night-eating syndrome (NES) and binge-eating disorder (BED). The management of obesity and eating disorders involves weight loss through increased physical activity and changes in dietary patterns aimed at reducing calorie intake. It also requires lifestyle changes such as adopting healthier choices and restricting certain foods. This book outlines the management of obesity and eating disorders in detail. It will serve as a valuable source of reference for graduate and postgraduate students of medicine.
