Summary

This study is a pilot trial of a smartphone app to promote sustainable and healthy eating, running for 10 weeks. The app is called "See Yourself Differently" (syd), which aims to promote general wellbeing in the working population. The investigators are interested in the feasibility and acceptability of the plant-based recipes and information pages, so the focus will be on how people engage with these features and how they meet their needs.

Participants will be randomised into three groups:

1. General information (no app)
2. syd app (app as it stands)
3. syd app with recipes and food education messages (app + messages)

Data on demographics and food choice will be collected at the start and end of the intervention. A subset of participants will also take part in short interviews to talk about their experiences.

Interventions

DEVICE

The "See Yourself Differently" app

As the app has not been evaluated before in terms of its impact on dietary change, the first intervention group will have the app as it stands. The overall aim of the syd is to improve general wellbeing across several health-related domains, which is achieved through engaging with its main features (the daily plan, journal, user profile, and chat function).

DEVICE

The "See Yourself Differently" app + messages

The plant-forward recipes and information pages available on the app will be made more salient for app users in this group through sending them via targeted messages in the chat function at specific times. Each day, the information pages will be sent at 09:30 and the recipes will be sent at 13:00.

BEHAVIORAL

General information

The (no app) control group will be sent general health and sustainability information via email immediately after randomisation is done. To incentivise participation in both baseline and follow-up assessments, the control group will be offered lifetime access to the app and a summary of their self-reported food intake at week 10. The control group will be sent one email reminder halfway through (week 5) to remind them that they are involved in the study, provide them with instructions on the follow-up assessment, and that they will receive the intervention and dietary feedback at week 10.
