This study was conducted to determine the glycemic responses, glycemic index (GI) and appetite effects of brown rice bars containing Hoodia gordonii and Kappaphycus alvarezii. After overnight fasting, twelve healthy volunteers consumed either HK1 (H. gordonii: 0 g, K.alvarezii: 0 g), HK2 (H. gordonii: 0 g, K. alvarezii: 2.8 g), HK3 (H. gordonii: 1.6 g, K. alvarezii: 0 g), HK4 (H. gordonii: 1.6 g, K. alvarezii: 2.8 g) or a reference (white bread) containing 50 g carbohydrates in five sessions. In each session, blood glucose and appetite assessments were performed before (0 min), and 15, 30, 45, 60, 90 and 120 min after food consumption. The energy intake (EI) assessment was performed at 120 min. Results showed that only HK3 was a medium GI food, whilst others were categorised as high GI. Consumption of HK3 provided the highest satiety and, the lowest motivation to eat and prospective food intake scores compared with other groups, but no significant difference (p>0.05) was shown. HK3 also significantly (p0.05) compared with HK4 and reference food. No significant difference (p>0.05) was shown by K. alvarezii in any of these parameters. In conclusion, consumption of H. gordonii affected GI, appetite and EI that may have potential in body weight regulation.
