Looking at that toned physique, it’s hard to believe that former Work Out star Jackie Warner was ever out of shape. But the 42-year-old trainer tells In Touch she had serious weight issues in college, when she ballooned from 118 pounds to 169. “I was alone in LA, and it was a huge culture shock,” recalls the Ohio native. “I was depressed and ate junk food every day.” Now starring on Thintervention (Mondays at 10 p.m. ET on Bravo), which helps people deal with the physical and emotional challenges of food addiction, Jackie opens up about how she took control of her body and life.
