Overweight and obesity threaten the health, functionality and quality of life of 77.2% men in West Virginia. The purpose of this study was to evaluate the feasibility and effectiveness of a 12-week primary care referred telenutrition weight loss intervention. Fifty-nine 40–70-year-old men with obesity were randomized to either the intervention group (n = 29) or an enhanced usual care (EUC) (n = 30) group. Participants from both groups were prescribed a moderate energy restricted diet (500–750 kcal/day below energy requirements) and provided diet-related educational materials; but, only those in the intervention group received weekly support from a registered dietitian nutritionist via telephone and videoconferencing. Both groups significantly reduced body weight, waist circumference, percent body fat and caloric intake and improved diet quality from baseline (p < 0.0001). Groups did not differ after controlling for time (all p > 0.30) and none of the group by time interactions were statistically significant. At week 12, a greater proportion of participants from the intervention group than the EUC group lost at least 5% of their baseline weight, (70.4% vs. 41.4%, p = 0.035). Retention rates and participant-reported adherence and satisfaction rates were ≥80% in the telenutrition group, thereby meeting the a priori criterion for feasibility of a larger trial. Primary care referred telenutrition interventions have the potential to improve access to dietary counseling for obesity treatment in health disparate populations. A larger longer-term trial is warranted.
