Purpose. This study identified restaurant manager/owner factors that may contribute to adoption of a restaurant-based healthy eating program, Eat Fit. Findings may be used to engage restaurants in efforts to increase access to and availability of healthy foods, promote healthy food choices, and work toward improving diet and lowering obesity and chronic disease risk in the community. Methods. Cross-sectional survey data were collected from restaurant managers/owners interested in partnering with Eat Fit. Variables included restaurant manager/owner beliefs, perceived staff knowledge/skills, support, self-efficacy, outcome expectancies, and barriers and facilitators to implementation. Results. Forty-nine managers/owners participated. Most managers/owners held positive beliefs about offering healthy food items in restaurants (83.7%). Most agreed that restaurants could influence eating behaviors (83.7%) and that restaurants have a responsibility to offer healthy options (77.6%). Most managers/owners perceived high levels of support (83.7%) and were confident in their ability (95.9%) to implement the Eat Fit program. The most cited barriers were customer preference, ingredient availability, staff knowledge, and operational challenges. The most common reasons for involvement in the program were a desire to increase access to healthy food, to entice customers looking for healthier food, a belief that restaurants should offer healthy food, and opportunities to market through Eat Fit. Conclusions. This research contributes to knowledge about beliefs and perceptions of restaurant manager/owners. Efforts to engage restaurants should focus on benefits of offering healthy food and the role restaurants can play in promoting health. Furthermore, programs may benefit from enhanced restaurant staff training, customer-targeted marketing, and educational efforts.
