Diagnosing insulin resistance via an OGTT can be costly and impractical. However, this information can be useful in recommending proper diet for individuals interested in losing weight. This study examined the association between responses to a 36 question carbohydrate intolerance questionnaire (CIQ) and responses to an OGTT in 108 women (31.6±13 yr, 34.7±7% body fat, 25.3±4 kg/m 2 ). Participants submitted to DEXA body composition, health marker determination, and underwent a serial sampled (0, 30, 60, 90, and 120 minutes) 75 g OGTT. We examined the relationship between CIQ questions and the 2hr OGTT sampling (G 120 ) and glucose AUC (G AUC ). Results revealed significant correlations (p<0.05) between G 120 (112±25 mg/dl) and perceptions of being >25 lbs overweight (r=0.25), waist:hip ratio (r=0.28), and BIA body fat (r=0.22). Results also revealed significant correlations (p<0.05) with G AUC (264±46 mg/hr/dL) to being overweight throughout life (r=‐0.19), being overweight since youth (r=‐0.27), gaining weight after age 30 (r=0.20), eating 3 meals/d (r=‐0.19), and waist:hip ratio (r=0.33). These findings indicate that OGTT G 120 and G AUC results correlate with simple CI questions and basic body comp/health measures that may help practitioners make more informed recommendations about appropriate diet interventions.
