miss A's Fei talked about competing on a survival cooking program during her KBS 2TV 'Happy Together 3' appearance on December 10!

"I always had a competitive streak," she started, "but I became even more competitive while doing the survival program.  The survival program kept going for about four to five months.  I got so stressed filming a survival program for a couple months.  In particular, it was difficult finding food ingredients or recipes written in Korean.  Because of my character, I had to know all recipes and food ingredients perfectly in Korean, so I always fell asleep reviewing them in Korean."

She then surprised everybody with the news that she lost 42 kg (~ 93 lbs) during the trial! You'd think you would eat more while on a cooking show, but she must've been way too stressed for that!
