FEASIBILITY OF A GENDER- AND CULTURALLY-SENSITIVEWEIGHT LOSS INTERVENTION FOR HISPANIC MALES

The investigators propose to 1) assess the feasibility, acceptability and preliminary efficacy of a gender- and culturally-sensitive weight loss intervention in 48 overweight/obese Hispanic males ages 18-64 over 12 weeks; 2) assess participant characteristics and process measures related to the uptake of mobile-health (mHealth) technology in overweight/obese Hispanic males over 12 weeks; and 3) assess pathologic changes in the liver in Hispanic men enrolled in a 12-week weight loss intervention using a non-invasive MRI as a therapeutic response biomarker.
