This document summarizes a study that explored young adults' perceptions of how social media influences their health behaviors related to diet and exercise. The study conducted focus groups and interviews with 34 young adults. It found that social media was perceived to both motivate and act as a barrier to exercise. Participants also felt that social media expanded their food choices through recipes and sharing food photos, but could also distract from making healthy choices. Many reported posting about exercise on social media. The study discussed these findings in the context of social ecological theory and how social media may impact individual health factors.
