Polycystic ovary syndrome (PCOS) affects £10 % of women of reproductive age in the UK (1) . Obesity and insulin resistance are common features of the syndrome with approximately 33 % of UK women with PCOS (wPCOS) being obese (2) and £80 % of wPCOS being insulin resistant (3) . Low-glycaemic index (GI) diets have been shown to be effective at improving insulin sensitivity and are proposed as a useful strategy for the management of insulin resistance in wPCOS (4) . The present research aims to

Dietary intake, GI and glycaemic load (GL) using a 7 d food diary were compared in thirty-eight wPCOS and twenty-eight age-and weight-matched controls (overall mean age 30.2 (SD 6.1) years). Weight and height were measured and BMI calculated. Fasting and 2 h insulin and glucose following a 75 g glucose tolerance test were measured and insulin resistance (HOMA index) calculated.
