Effect of kcal and PACE Labelling on Self-served Portion Size

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).

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • United Kingdom residents
  • Age ≥ 18
  • Fluent in English
  • Have access to a computer and Internet

Exclusion criteria

  • Have any dietary restriction (vegetarian, vegan, gluten-free, sugar-free, diary or lactose free, food allergy)

Treatment and study plan

Kcal labelling

Behavioral

Real-time kcal counter synchronised with the food amount changes

PACE labelling

Behavioral

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

Primary outcomes

  1. Total self-served energy (kcal)

    Time frame: 10 minutes (the time frame denotes time taken to perform the portion selection task and there is no follow up)

    Energy content of the portion selected for each dish.

Secondary outcomes

  1. Kcal influence

    Time frame: 3 minutes (the time frame denotes time taken to fill in the debriefing questionnaire and there is no follow up)

    Whether kcal content influences the quantity of self-served food

  2. PACE influence

    Time frame: 3 minutes (the time frame denotes time taken to fill in the debriefing questionnaire and there is no follow up)

    Whether physical activity energy equivalent influences the quantity of self-served food.
