Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Kcal labelling

Participants allocated to this group will see on the screen the amount of food increasing or decreasing based on how many times they tap on the corresponding keys and a real-time kcal counter synchronised with the food amount changes (i.e., increasing/decreasing).

Group Type EXPERIMENTAL

Kcal labelling

Intervention Type BEHAVIORAL

Real-time kcal counter synchronised with the food amount changes

PACE labelling

Participants allocated to this group will see on the screen the amount of food increasing or decreasing based on how many times they tap on the corresponding keys and a real-time PACE counter (as minutes needed to walk to burn off the calories) synchronised to the food amount changes (i.e., increasing/decreasing) with 4 min being equivalent to 20 kcal.

Group Type EXPERIMENTAL

PACE labelling

Intervention Type BEHAVIORAL

Real-time PACE counter (as minutes needed to walk to burn off the calories) synchronised to the food amount changes

Kcal and PACE labelling

Participants allocated to this group will see on the screen the amount of food increasing or decreasing based on how many times they tap on the corresponding keys and a real-time kcal and PACE counters synchronised to the food amount changes (i.e., increasing/decreasing).

Group Type EXPERIMENTAL

Kcal labelling

Intervention Type BEHAVIORAL

Real-time kcal counter synchronised with the food amount changes

PACE labelling

Intervention Type BEHAVIORAL

Real-time PACE counter (as minutes needed to walk to burn off the calories) synchronised to the food amount changes

No labelling

Participants allocated to this group will only see on the screen the amount of food increasing or decreasing based how many times they tap on the corresponding keys.

Group Type NO_INTERVENTION

No interventions assigned to this group
