Even after losing 42 lbs., dropping five dress sizes and winning the fourth season of VH1’s Celebrity Fit Club, Tina Yothers still didn t realize how much her body had changed – until she tried to toast her victory at one of her favorite L.A. eateries, In-N-Out Burger.
At the drive-through, Yothers ordered her usual, a double-double burger, but couldn’t finish it. “I took, like, three bites – that s all I could do! she tells PEOPLE.
Besides cutting back on portions (she follows the NutriSystem plan), Yothers, 33, continues to work out three times a week with her trainer, doing lots of cardio (jumping rope is a favorite) as well as lunges and squats, and is down to a size 8.
“We call each other from our workout sessions and we’re huffing and puffing,” says fellow Fit Club-er Carnie Wilson, who became good friends with the actress during the show.
Yothers – who a year ago hit 210 lbs. while pregnant with daughter Lillian Grace – now celebrates by showing off. “We’ve gone to the river three times this year,” she says, “and I ve worn a bikini every time!”
