Clinical Trial Summary

Participants will take part in an online survey. They will be asked to choose the amount of food they would like to eat based on pictures of 18 dishes sequentially displayed on the screen. They will be randomly allocated to four different groups: kcal labelling, PACE labelling (Physical Activity Calorie Equivalent: minutes to walk to burn off the calories), kcal and PACE labelling combined, no labelling, in a between subject design. The main outcome variable is the total "self-served" energy for each dish (in kcal).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Total self-served energy (kcal)	Energy content of the portion selected for each dish.	10 minutes (the time frame denotes time taken to perform the portion selection task and there is no follow up)
Secondary	Kcal influence	Whether kcal content influences the quantity of self-served food	3 minutes (the time frame denotes time taken to fill in the debriefing questionnaire and there is no follow up)
Secondary	PACE influence	Whether physical activity energy equivalent influences the quantity of self-served food.	3 minutes (the time frame denotes time taken to fill in the debriefing questionnaire and there is no follow up)
