During his two performances at the CMAs last week, Zac Brown Band frontman Zac Brown put his musical prowess on display, but fans might have also noticed that the 'Goodbye in Her Eyes' singer has been looking trimmer and healthier these days.

Brown says he's cleaned up his eating habits, which has him looking thinner. "I've been on a raw diet. I've been trying to eat good and feel better," Brown told radio station KNIX. "I've got four girls at home and all these businesses and building this camp, so I've got to be on it, man. It's definitely pushing my food expiration to a whole other thing."

Brown, an avid businessman, has several new projects in the works, including his Southern Ground recording studio that just opened in Nashville, as well as Camp Southern Ground in Fayetteville, Ga., which provides a place for children of differing abilities, socioeconomic backgrounds, races and religions to experience personal growth through a range of recreational and educational activities.

The singer reveals that his healthy new diet consists largely of  raw vegetables, raw fruits, raw nuts and other clean foods. "I will eat some sushi occasionally. I try to eat everything that's not cooked," Brown reveals. "There's a whole lot of stuff out there. If I ever go back to a balance of a regular thing, I definitely have some new arsenal to go to for flavor."

This makes us wonder if more raw foods might show up on the menu for the band's popular eat-and-greets prior to their concerts!
