 The investigators propose a pragmatic, randomized controlled trial RCT to examine the feasibility, acceptability, and preliminary efficacy of a MT intervention for weight loss in overweight and obese men in a practical, real-life rural environment. This 6-month pilot RCT includes a 3-month intervention with 6-month post-baseline follow-up. The intervention group n40 will receive a 3-month MT intervention using the Lose-It Premium mobile phone app with social comparison group, behavior change text messaging, and daily self-weighing via Wi-Fi scale. The comparison group n40 will receive the Lose-It Basic mobile phone app only MT. Primary efficacy outcome will be loss of body weight kg body weight at 3 and 6 months. Secondary outcomes will be improved diet and increased physical activity PA. A multi-method formative evaluation of the intervention student outreach, community advisory board CAB, community capacity surveys, focus group, community dissemination will occur across the study. Primary feasibility outcomes will include recruitmentretention rates and community resource development for program sustainment. The multi-modal feedback will help 1 facilitate recruitment of a hard-to-reach population, and 2 inform intervention feasibility and acceptability. These local insights may foster minimized attrition and improve future study outcomes. The specific aims of this study are:
