These include books, magazines and Internet based diets and programmes. There is a vast choice available of widely varying quality. Some can be very helpful, and many are fad diets. Apply the British Dietetic Association’s ‘It’s a fad diet’ test (see below) to check a new diet out. If it isn’t a fad, see how it rates against the ‘responsible diet’ guide at the start of this section.  Since different approaches suit different people, an Internet or self-help book may be the approach that suits you best.
