Study type
Interventional
Description of intervention(s) / exposure
The study is a randomised 2x2 factorial design with a high/low fibre beverage consumed with a high (65%)/moderate (40%) fat breakfast test meal. Participants will maintain a typical 'western diet' (total fat providing 30% of daily Energy) for the duration of the intervention. Participants will consume each of the 4 test meals over a two week period to allow for adequate washout period (4 days)between test meals. Dietary compliance will be assessed by dietary records. Ileal efflux is collected at regular intervals (2 hours) for the duration of the study to measure fat excretion.

Statistical methods / analysis
Recruitment of 6 participants will give 80% power to detect a 2.5 fold difference in ileal fat excretion. Withdrawal rate in these interventions is low to nil so there will be a maximum recruitment of 8 participants required.
