Brief summary
This study aims to assess the effects of a new approach to food labelling called physical activity calorie equivalent (PACE) labelling. PACE food labelling provides the public with information about how many minutes (or miles/kilometres) of physical activity (e.g. walking or running) are equivalent to the calories contained in foods.
Interventions
BEHAVIORALPACE plus calorie labelling information
The intervention group will be exposed to PACE plus calorie labelling information via Instagram and Twitter social media posts every day for 13 weeks.
BEHAVIORALCalorie-only labelling information
The comparator group will be exposed to calorie-only labelling information via Instagram and Twitter social media posts every day for 13 weeks.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in eating behaviour of discretionary foods at 13 weeks | Pre-baseline (one time point prior to randomisation) and post-intervention (one time point after week 13) | Eating behaviour of discretionary foods will be assessed by a modified version of Online Food Frequency Questionnaire (eNutri FFQ), designed to measure habitual food intake. Participants will record frequencies of discretionary food and drink items eaten during the last month (e.g. 1/week or 1/day). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Cognitive restraint of eating | Pre-baseline (one time point prior to randomisation) and post-intervention (one time point after week 13) | A modified version (R18) of the Three-Factor Eating Questionnaire (TFEQ) will be used to measure cognitive restraint. |
| Physical activity | Pre-baseline (one time point prior to randomisation) and post-intervention (one time point after week 13) | Self-reported physical activity behaviour will be assessed using the 7-day International Physical Activity Questionnaire (IPAQ) |
| Body weight | Pre-baseline (one time point prior to randomisation), mid-intervention (week 7) and post-intervention (one time point after week 13) | Weight will be self-reported via participants own weighing scales. Participants will electronically send via email photograph evidence of readings of their fasted morning weight from weighing scales, following standardised instructions. |
