Study type
Interventional
Description of intervention(s) / exposure
The aim of this trial is to assess the effect of the particle size of orally ingested dairy-derived lipid emulsions on hunger, satiety and energy intake at a single ad libitum meal in human volunteers.
This study involves 4 visits to the Human Nutrition Unit. The first will be a brief screening visit (~30 minutes) where subjects will give their consent & complete questionnaires concerning their medical history, weight loss history & food preferences. We will also gather demographic & anthropometrical data (age, gender, ethnicity, height, weight, body mass index (BMI) and waist & hip circumference). The trial design is a 3 treatment crossover, single day intervention study, comprising 20 lean male subjects (BMI = 18-25kg/m2) aged 18-65 years. At 9am on the morning of each visit subjects will be provided with a yoghurt breakfast containing of one of the 3 dairy treatments (10g emulsion or non-emulsion). Subjects must consume the breakfast meal in full. 3 hours later an ad libitum lunch meal will be provided. There will be a washout period of 3 days between study visit days. Each participant will complete all study arms of the study in a randomized order.

The 3 treatments are:
A = Small particle size dairy lipid/phospholipid emulsion
B = Large particle size dairy lipid/phospholipid emulsion
C = Non-emulsified dairy lipid/phospholipid

The breakfast meals will comprise 10g of the dairy lipid treatment mixed in to a 190g yoghurt (total weight = 200g)

The lunch meal will provide items served in moderate excess & participants will be instructed to eat as much or as little as they like until they feel comfortably full.

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 was 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
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
