Steady readers will know that I'm a big proponent of treatment for food addiction. In 1991, I got it — nine weeks in the eating disorders unit of an accredited psychiatric hospital, and it was one of the most important interludes of my life.

I don't want to go into the reasons why, but that sort of treatment is far less available today, and making a case for the diagnosis of food addiction, so that insurance will support its treatment, is the primary reason I wrote my book.
