Study Summary
This randomized controlled trial will assess the effects of External Cues focused messaging (i.e., government recommendations of MyPlate) compared to Internal Cues focused messaging (i.e., intuitive eating). The investigators will collect data on within-person changes in psychological (e.g. affect) and physiological (e.g. heart rate variability) outcomes in female college students. Participants will be randomly assigned to one of two study conditions. In condition one, participants will view a five-minute video focusing on traditional nutrition education principles. In condition two, participants will view a five-minute video focusing on intuitive eating principles.
Primary Outcome
Heart rate variability measures the variation in time between each heartbeat. This will be measured using Firstbeat Electrocardiograms (ECGs) that participants will attach to their chest using two electrodes.
