When most The Biggest Loser contestants are eliminated, they devote themselves solely to their weight loss. But Ruben Studdard is more focused on something else – his career.
“It was difficult leaving,” the American Idol winner told reporters after being eliminated from the NBC weight-loss show. “But I had a lot of work waiting on me when I left the ranch. As soon as the next day started, my work started.”
The “Sorry for 2004” singer is currently working on a new album with producer David Foster and will be heading out on a Christmas tour with CeCe Winans, Peabo Bryson and Melissa Manchester.
“I will be out the whole holiday season so I won’t be home, but if I was, we would definitely be having a healthy Christmas this year,” Studdard, 35, said.
“I don’t think there was at all any conspiracy to bring me back,” said the self-described “sexy” singer. “My only concern was my health.”
Studdard – who arrived at the ranch weighing 462 lbs. – is now down to 349 lbs. and hopes to continue his weight-loss journey through to the finale.
“I celebrate every pound I lose,” said Studdard, who recently completed a 5K run. “I thought after a mile or two I would be winded but I was fine. I’m in much better physical condition.”
And if Studdard happens to win the at-home weight-loss prize, he already has an idea of what to do with the $100,000.
“I’ll probably donate most [of it] to my foundation,” he said.
