Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will be asked to present at 4 x test sessions of approximately one hour duration, facilitated by the Chief Investigator of this research project. Participants will be served a breakfast to be taken ad libitum. The degree of satiation will be assessed via the measurement of the energy intake of food consumed prior to the voluntary cessation of eating and by the recording of patient appetite sensations using Visual Analogue Scales (VAS). There will be two intervention arms. Arm 1: a preload containing 20g of fat followed by a low energy dense carbohydrate meal; and Arm 2: a preload containing 60g of fat followed by a low energy dense carbohydrate meal. Consumption of the preload will be verified and recorded by the researcher. After a period of fifteen minutes the subject will be asked to consume the test meal. Subjects will be asked to eat at a consistent rate by means of a metronome but only until a point of pleasant fullness has been reached. Meals will be matched for palatability prior to the commencement of the study.

Comparator / control treatment
The control will consist of two arms. Control Arm 1: a preload containing 20g of fat followed by a higher energy dense carbohydrate meal; and Control Arm 2: a preload containing 60g of fat followed by a higher energy dense carbohydrate meal.

Outcomes
Primary outcome [1] 326080 0
Before the commencement of the meal, the dish containing the meal will be weighed. At the completion of the meal the dish will again be weighed, the difference in the weight of the dish between the commencement and completion of the meal being the weight of food consumed. Energy intake of food will be calculated by measuring net quantity of food consumed by participants and assessing the number of kilojoules ingested by means of the nutrition app FoodWorks.
Timepoint [1] 326080 0
Point of participant satiation (meal termination).
Secondary outcome [1] 390059 0
Minutes to meal termination as assessed with a timer to be activated at the point where participant has been instructed to consume the test meal
Timepoint [1] 390059 0
Point of participant satiation (meal termination).

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation involved contacting the holder of the allocation schedule who was "off-site" or at central administration site.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (i.e.
https://www.random.org/lists/)
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?

Efficacy
Statistical methods / analysis
Difference in energy intake and time to satiation between the low energy density carbohydrate and higher energy density carbohydrate groups will be analysed by a t-test. Difference in VAS scores between the two groups will be analysed by a Wilcoxon signed rank test.
