During the 1970s, Dr Howard worked with Dr Ian McLean-Baird, of the West Middlesex Hospital, to develop what they regarded as the "perfect diet". Supported by a lectureship from Downing College, Cambridge, and various grants, the pair set up a research project at the West Middlesex Hospital. Their aim was to create a formula food with excellent weight loss properties but no undesirable side effects. It needed to contain the right level of protein to protect lean tissue; the right level of carbohydrate to promote a mild ketosis and eliminate hunger, and the right level of vitamins, minerals, trace elements and essential fatty acids to maintain good health.
Cambridge Weight Plan continues to pioneer research in Very Low Calorie Diets and has helped millions of people worldwide to reach and maintain a healthy weight.
