Oh I have that somewhere
Unfortunately Paul McKenna did not make me skinny but I remember the book made a whole lot of sense and explained the mentality of dieting or of growing up being told to finish your plate
I followed it for a while and listened to the CD a lot (same as you- about 10years ago)
Tempted to try to find it for a bit of a read
I follow low calorie and low carb but I incorporate ideas from other diets like 5:2 or 5-bite
