(PEOPLE) — Ruben Studdard has already won the title of American Idol. Now he may become The Biggest Loser.
The “Velvet Teddy Bear,” who won season 2 of the Fox singing competition in 2003, will compete on the NBC weight loss show as he attempts to battle his obesity – a task he has attempted previously with limited success.
“I was losing weight, but I was exhausted. It was making me sick,” the 35-year-old told PEOPLE in 2006 after attempting an intense workout regimen on about 1,200 calories a day with trainer Gunnar Peterson. “I’m a big man. There was no way to do those workouts on that amount of food, so everything was contradicting itself.”
