Impact of ß-glucan Supplementation on Subjective Appetite and Gastrointestinal Appetite Hormones.

The goal of this clinical trial is to how supplementation with beta -glucan during two days of caloric and carbohydrate restriction impacts subjective appetite and gastrointestinal appetite hormones in healthy overweight adults. In addition, the study aims to investigate the impact on gastric emptying since appetite and energy intake following food or supplement consumption can also relate to their impact on gastric emptying and as reduced hunger and enhanced satiety have been reported to be linked with delayed gastric emptying. The study will also investigate how these interactions impact after meal responses of insulin and glucose and thus insulin sensitivity. The caloric restriction during breakfasts and dinners will be achieved by low-calorie ready meals in the format of the counterweight PRO800 diet and lunches will be low in carbohydrates. It aims to test whether the addition of β-glucan to calorie and carbohydrate-restricted meals amends postprandial responses of appetite hormones and subjective appetite. participated will be assigned in double-blinded randomised crossover study, intervention group will be supplemented with 3g beta-glucan and the control group supplemented with 3g placebo.
