NCT05981404

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Changes in gastrointestinal appetite hormones and appetite scores between the two groups.

    Taking blood samples every 30 minutes to test the changes in appetite hormones. Asking participants to answer questionnaires which will be calculated by Validated Visual Analogue Scale (VAS). The scale is 100 mm in length with words anchored to a minimum and a maximum of the ''desire to eat'', ''fullness'', ''hunger'' and ''satiety'' the point corresponding to their sensations.

    On day 2 of each experimental trial.

Study Arms (2)

Low calorie and low carbohydrate meals with β-glucan.

EXPERIMENTAL

On day 1, a low-calorie breakfast will be consumed at the metabolic investigation laboratory at New Lister Building (NLB) of Glasgow Royal Infirmary but low carbohydrate lunch and low-calorie dinner at home. On day 2, breakfast and lunch will be consumed at the laboratory and, prior to the breakfast, 1000mg of paracetamol will be taken, blood samples, breath hydrogen tests, appetite questionnaires will be obtained for 7 hours after the completion of breakfast. 3g β-glucan will be consumed with each meal on both days.

Dietary Supplement: β-glucan

Low calorie and low carbohydrate meals with placebo.

Eligibility Criteria

Age18 Years - 50 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Participants will be asked to confirm whether they had stable body weight for at least 3 months and are not following a diet to gain or lose weight. They will also be asked to confirm that they are non-smokers, not on long-term medication, not pregnant or lactating, and have no known food allergies to the ingredients in test meals and to Paracetamol.

You may not qualify if:

  • Participants will be excluded if they are smokers and have irregular menstruation cycles, use any type of medication, exercised more than 75min a week, were pregnant or lactating. Participants will be required to be free of any medical condition, including having food allergies and stable body weight for at least 3 months preceding the study. Participants will be excluded if they are allergic to paracetamol and any types of food and were following any weight loss diet for the last 3 months, are vegan or vegetarian or follow any diet other than the typical Western diet. Participants will be expected to be not on any kind of dietary supplement at the time of the study.
