BACKGROUND: There is limited evidence for effective obesity treatment programs that engage men. PURPOSE: This study evaluated the efficacy of two gender-tailored weight loss interventions for men, which required no face-to-face contact. METHODS: This was a three-arm, randomized controlled trial: (1) resources (n = 54), gender-tailored weight loss materials (DVD, handbooks, pedometer, tape measure); (2) online (n = 53), resources materials plus study website and e-feedback; and (3) wait-list control (n = 52). The interventions lasted 3 months and were grounded in social cognitive theory. RESULTS: At 6 months, significantly greater weight loss was observed for the online (-4.7 kg; 95% CI -6.1 to -3.2) and resources (-3.7 kg; 95% CI -4.9 to -2.5) groups compared to the control (-0.5 kg; 95% CI -1.4 to 0.4). Additionally, both intervention groups significantly improved body mass index, percent body fat, waist circumference, blood pressure, physical activity, quality of life, alcohol risk, and portion size, compared to controls. CONCLUSIONS: Men achieved significant weight loss after receiving novel, minimal-contact, gender-tailored programs, which were designed for widespread dissemination.
