Love Hunger Weight-Loss Workbook is very helpful although some of the dietary suggestions aren't as healthy as they were believed to be when this book was first written in 1he 90s (for instance using margarine instead of butter).
As regards recovering from food addiction, the information is solid and still applies. All that's needed is a newer or more current books on health and nutrition and you're good to go. Overall, very supportive with helpful guidelines and exercises.
