The ancestry of anorexia - blame biology, not parenting

The ancestry of anorexia
Blame biology, not parenting, new theory suggests
By Ellen Ruppel Shell, Globe Correspondent, 12/30/2003

Anorexia, the most lethal of psychiatric disorders, afflicts as many as 1 percent of young women and about a tenth as many men, and casts a Svengalian spell, leading its victims to willingly starve themselves in the midst of plenty. Now, psychologist Shan Guisinger has developed a radical new view of anorexia that she says explains both the bizarre features of the illness -- self starvation and hyperactivity -- and its resistance to treatment by traditional psychotherapy.

Anorexia, she contends, is not primarily a psychological condition brought on by a troubled childhood -- as is often thought -- but a disorder based in biology, specifically in the appetite regulation mechanism in the brain. Her theory postulates that anorexics have a biological adaptation to weight loss that causes their bodies to shut off hunger signals, and to ratchet up physical activity, even as their flesh melts away.
