Procedure
Participants were invited to take part in a two-part online study on Prolific, after which they were reimbursed for their participation (for both parts; £6.00/h). Before agreeing to take part in the study, participants were informed that they would need to consume a chocolate bar before the study commenced and that they would need to eat chocolate during the study. Participants first viewed the participant and consent forms, and upon consenting, completed a demographics page and the MEBS-T. On completion of the MEBS-T, participants were randomly allocated to either the experimental or control group. Both groups were then directed to the chocolate that they were asked to bring for this study. Along with a 10-min countdown, a written message was presented on the screen: “At this point, you get 10 min to enjoy your chocolate. Please have your chocolate (ideally a chocolate bar), and after 10 min you will be directed to finish the study. If you finish your chocolate before the 10 min, press the button below to continue.”The experimental group further received the Mindful Eating Behaviour Practice (MEBP—see Additional file 1) [
