Reddit reviews Overcoming Your Eating Disorder, Workbook: A Cognitive-Behavioral Therapy Approach for Bulimia Nervosa and Binge-Eating Disorder (Treatments That Work)

It’s called Overcoming Your Eating Disorder Workbook. It’s blue and gold. I got it off amazon.

Here’s the link: Overcoming Your Eating Disorder

You should find a therapist that does Cognitive Behavioral Therapy, the gold standard for psychotherapy, especially for BED. You can also start with a good CBT book, such as this one. I have that book, and love it. It is not especially about BED, but the skills it teaches can definitely help with BED. There are other ones especially for BED, like this one, which I don't know anything about.

Either those CBT books, and others, can be used alongside a therapist, and they may have more to recommend.
