Imagine you have been told that so many of your favourite dishes are now off-limits: chocolate, cake, roast potatoes, or whatever. Well, that's the prospect that doctors deal out to increasing numbers of patients every day. With this in mind, we commissioned Good Housekeeping writer, Carolyn Humphries, to devise a diet plan, which removed the harmful fat and salt without removing all the favourite 'sinful' foods as well. Here, Carolyn explains the health issues and then, in a seven-day recipe programme, shows readers how they can change their eating habits without sacrificing good, enjoyable, satisfying food.
