NCT07048483

Brief Summary

The goal of this study is to examine how different types of health messages affect people's self efficacy for healthy eating and diet quality. Eligible adult participants with overweight/obesity will be randomized into one of two groups: the intervention group, which will engage with audio-visual messages per week for four weeks, or the control group, which will not engage with any audio-visual messages but will receive written educational materials about healthy eating per week for four weeks.
