No, it wasnt Rosemary Conley. It was called something like the 'Fat Unit Diet' and I think the magazine was called, Slimmer. Found a few bits and bobs on it at home, and its basically eat less than 30g of fat per day, and sensibly otherwise.
I will keep my research up and let you know if I come across any more info on it, I remember it was easy at the time, but old age and memory loss doesnt help

Good luck everyone,
TC
