Eating disorders are defined as an abnormal attitude towards food, leading to either excessive or insufficient food intake, and causing the sufferer to change her/his eating habits and behavior. Because of this, eating disorders can trigger serious problems related to weight, healthy diet and eating, or body image. Although, eating disorders are known to start more often in teens and young women, a new study from the Eating Disorders Program at the University of North Carolina School of Medicine, USA, found that more than 60 % of women over 50 said their body weight or shape negatively affected their lives.
