Subtle Signs of Eating Disorders
Cooking elaborate meals for others
Although people with anorexia may refuse food themselves, they are often eager to see others eat, sometimes going so far as to prepare elaborate meals for friends and family. This may be a form of vicarious pleasure, or eating "through" others.
Similar behavior was observed in the famous Minnesota Starving Experiment, conducted in the mid-1940s. Volunteers who were semi-starved and lost more than 25% of their body weight became obsessed with food and eating. Several of the men became collectors of cookbooks and recipes, a behavior that has been noted in people with anorexia as well.
