Description of intervention(s) / exposure
This will be a double-blind crossover trial in which 77 healthy adults will eat trifle for lunch containing either 73g of sucrose or isomaltulose. The order in which participants receive the trifles will be randomised to each person. There will be a 2 week washout between test days. After an overnight fast of 8h, on the mornings of the test days, participants will be provided with the same breakfast cereal to standardise the mormings food intake. The breakfast will be consumed at a time convenient to the participant, but at the same time on both test days. Between finishing breakfast and lunchtime, participants will be asked to abstain from food and drink, apart from water. At 12pm, participants will eat 446g of trifle within 15 minutes. Eating lunch and assessment of satiety questions will be under the supervision of the study investigators. Participants will record food and beverage intake throughout each test day (midnight to midnight)

Outcomes
Primary outcome [1] 306537 0
Satiety assessed via the use of visual analogue scales (Likert) in response to four appetite questions (subjective).
Timepoint [1] 306537 0
The set of four questions will be asked at baseline and at 30, 60, 90, 120 and 150 minutes after eating the trifles. The primary timepoint will be a summary measure area-under-the-curve up to 150min.
Primary outcome [2] 306538 0
Participants will record 24h food and beverage consumption via a weighed food record
Timepoint [2] 306538 0
24h period covering midnight to midnight on each test day. The primary outcome will be a summary measure of intake commencing after trifle consumption to 12am of the test day.
Secondary outcome [1] 348807 0
Blood glucose concentration in response to trifle ingestion
Timepoint [1] 348807 0
Baseline, 60 and 120 min following trifle ingestion

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All participant names will be entered into a dataset. A random number generator will be used to generate a random number next to each participant. The dataset will be sorted in ascending random number order. On the first test day, the first 39 participants in the sorted dataset will be allocated one treatment and the last 38 participants the alternative treatment; on the second test day, the treatments will be reversed (crossover). Randomisation and the supply of trifles to participants will be undertaken by a University staff member otherwise uninvolved in the study. Allocation concealment will be achieved by central randomisation by computer.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
The people assessing the outcomes
The people analysing the results/data

Efficacy
Statistical methods / analysis
A sample of 60 will be required to detect a difference of 0.5 standard deviations for all outcomes in standardised form. A larger number of participants will be recruited to allow for dropout. The study will have 90% power to the 1% significance level to detect this difference. Mixed effects regression analysis will be used to test for differences in satiety questions with participant as a random effect. Estimates will be adjusted for baseline and for the randomised order in which the participants received their trifles.
