 As part of routine care these patients will be seen by a dieticiandiabetes specialist nurse DSN before and after intervention. Patients will be asked to prospectively complete food diaries on three consecutive days which are representative of their usual dietary intake. The first food diary will be completed three months to two weeks pre intervention. Another four food diaries will be completed post intervention: at one, three months, 6 months and one year. Total energy intake and macronutrient composition comparisons pre and post intervention will form the basis of our analysis.
