 Overweight and obese men in rural Northeast Nebraska are an unrepresented, at-risk group exhibiting rising rates of cardiovascular disease, poor access to preventive care, and a rural milieu that contributes to their sedentary physical activity and unhealthy diet. This study proposes to use a pragmatic randomized controlled trial and community engaged research approaches to 1 determine the feasibility and acceptability of a smart phone self-monitoring app Lose-It Premium plus text-based coaching and daily weighing via Wi-Fi scale intervention for achieving weight loss, 2 determine preliminary efficacy of this intervention group to a comparison group receiving only a self-monitoring app Lose-It Basic in achieving the outcomes of weight loss kilogram and improved dietary and physical activity behaviors secondary at 3 and 6 months post-baseline, and 3 determine quantitative and qualitative indicators of community capacity to support a contextually relevant weight loss intervention. Eighty men ages 40-65 with body mass index of 28-45, randomly assigned 1:1 ratio to intervention group or comparison group. Men will complete baseline assessments weight, body fat, body mass index height, blood pressure, health history, dietary intake, physical activity frequencyintensity and receive orientation to the mobile technologies Lose-It app features, text messaging, Wi-Fi scale. Men will track their dietary intake, physical activity, and weight on the Lose-It app for 12 weeks. After the 3-month intervention, post-measure assessments weight, body fat, BMI, dietary intake, PA frequencyintensity, technology usability surveys will be collected at 3 and 6 months post-baseline. At 6 months post-baseline, two groups n8 each of intervention completers will be purposively selected to share their perceptions of the intervention efficacy in an evaluative focus group. A community advisory board comprising local leaders within the mens social network, together with investigators and rural student nurses will guide community outreach efforts for study recruitment, implementation and evaluation. Study findings will be evaluated with the community to inform local dissemination, future intervention revision, and determination of community capacity for support of a larger clinical trial.
