Evening dietary habits may affect endocrine activity and glycemic response the following morning. This may influence the high fasting glucose levels often observed in type 2 diabetics (Dawn Effect). This study determined the effect of evening milk consumption on morning glycemic response. Healthy subjects (19 ± 1 yr; BMI 23 ± 1) were randomized into groups that consumed either 355 mL of 2% cow's milk (n=43; 183 Cal) or 355 mL water (control; n=42) nine hours prior to an oral glucose tolerance test (OGTT=50g/255 ml). Following an overnight fast from all foods/beverages except water and a 15‐minute acclimation period after lab arrival, baseline blood glucose was measured (0 min). Blood glucose was re‐assessed 30, 60, 120 minutes post‐OGTT. Blood glucose in evening milk consumers at 0, 30, 60, and 120 min was 84.6 ± 1.4, 136.8 ± 3.7, 138.1 ± 4.0, and 103.8 ± 2.8 mg/dL, respectively. Control blood glucose was 82.4 ± 1.5, 130.8 ± 3.3, 130.7 ± 4.2, and 105.0 ± 3.0 mg/dL, respectively. Blood glucose AUC for milk‐ and water‐ pre‐OGTT was 13710.8 ± 316.6 and 14089.7 ± 313.0. Glycemic responses displayed no significant differences between milk and control treatments. Evening milk consumption does not appear to alter morning glycemic response in healthy, non‐diabetic subjects. However, influence of evening milk on AM glycemic status remains to be tested in type 2 diabetics.
