Description of intervention(s) / exposure
This study will investigate the potential of two dairy derived extracts to improve symptoms of the Metabolic Syndrome, including fatty liver, serum lipid and glucose profiles & markers of inflammation, in individuals with the Metabolic Syndrome. The target population would be individuals identified as overweight with central adiposity, metabolic syndrome, abnormal liver function and fatty liver as shown by an ultrasound scan.

Participants will be randomised to recieve one of the 2 dairy fractions or a control for a period of 3 weeks, followed by a minimum 3 weeks wash out period between active treatments or control. All participants will complete the three treatment arms.

The dairy fractions differ from each other in that one is a high-carbohydrate fraction while the other is a high-lipid (fat) fraction. The dose of the carbohydrate fraction is 10g/day (138kJ) while the dose of the lipid fraction is 4g/day (138kJ). The doses were selected so as to match treatments for total energy (kJ). The dose of the control treatment is 6.5g/day (138kJ).

The administration vehicle for this study will be a chocolate dairy dessert. All treatments will be incorporated into 150g fresh dessert and consumed daily.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
This is a randomised, cross-over trial. Randomisation is carried out using a Latin square design, whereby next patient registered is allocated to the sequential randomisation code. Participants are randomized to receive all 3 treatments.
Allocation is not concealed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A Latin square will be used to randomise the subjects to each of the 3 intervention arms. Each participant is randomized to complete all 3 intervention arms.
Masking / blinding
