Abstract
The purpose of this study was to examine whether different types of posts differentially affect participant engagement and if engagement with social media enhances weight loss. Data are a subanalysis from a randomized weight loss study with a 4-month follow-up support period via private Facebook groups and monthly meetings. Counselors posted five different post types/week based on social cognitive theory (weight-related, recipes, nutrition information, poll votes, or requests for suggestions). Types of participant engagement (likes, comments/poll votes, and views) were assessed. Poll votes were the most engaging (mean number of votes or comments/poll 14.6 ± 3.4, P < 0.01) followed by suggestions (9.1 ± 2.7 posts, P < 0.01) and weight-related posts (7.4 ± 3.1 posts, P < 0.01). Engagement with Facebook was significantly associated with weight loss during the 4-month maintenance period (B = −0.09, P = 0.04). The findings provide evidence for ways to provide social support during weight loss interventions using remote methodology.

Implications
Practice: Prompts soliciting feedback, such as polling features and suggestions, prompt the most engagement among participants and should be used in the context of social media based interventions for weight loss.
Policy: Future public health initiatives may want to consider offering group support via social media when face-face support from clinical staff decreases.
Research: Future studies should examine if social support provided via social media groups differs from support delivered in traditional clinical settings.
