High glycemic carbohydrates (CHO) foods provide an elevated glucose response resulting in lower food intake at a later meal. The present study was designed to test if the glycemic response of CHO predicts satiety and food intake (FI). Mashed potatoes (MP) and white bread (WB) were compared to oats, chick peas (ChP) and water (control). Twelve young normal‐weight female volunteers consumed the test foods providing 50g available CHO after an overnight fast once a week in random order. Both visual analogue questionnaires to measure appetite and finger prick blood glucose testing were taken at 0, 15, 30, 45, 60, 90 and 120 min. An ad libitum pizza meal was consumed at 120 min to assess FI. Incremental area under the curve (iAUC) for both blood glucose and appetite was higher after MP and WB (p<0.001). FI (calories mean ± SD) was lower after ChP (533±112) b and oats (607± 128) b than after MP (745± 35) a , WB (742± 176) a and water (762 ± 147) a (p<0.0001). FI had a positive (p<0.0001) correlation with appetite yet no correlation (p=0.9) with glycemic response We conclude that 1) glycemic response is not a reliable predictor of food intake, 2) low glycemic foods prevent rapid rise in blood glucose and 3) suppress both appetite and FI in young female Kuwaiti adults.
