Under the guidance of the Consumers' Association, dieticians have produced a definitive diet for health. First, you must share your personal details with the computer; then, in response, the computer will help you choose an appropriate and individual weight-loss plan.

Next it offers you a calorie counter and a series of apposite menu suggestions to help stimulate your imagination when you just can't think what to eat. All this is set in the context of advice about the composition of your diet and its affect on your health. Finally, once a week, you can go to the computer and ask it how well you are doing.
