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).
