On The Biggest Loser Season 15 final, we learned (again) that Ruben Studdard can definitely sing.

The former American Idol champion - and eliminated NBC reality show contestant - belted out a ballad about following one's dreams. Such a sentiment certainly applied to all three finalists.

But, between David Brown, Rachel Frederickson and Bobby Saleem, only one would see his/her dream of winning $250,000 fulfilled?

Who would it be? Bobby hopped on the scale first, showing off an impressive loss of 188 pounds, equal to 52.5 percent of his original body weight.

Rachel then took her turn and beat him out, shedding an amazing 59.6 percent of hers.

Could David top that figure? Nope. His 54.3 percent was impressive, but not good enough to deny Rachel this weight loss crown.

"I was shocked," Frederickson told People after being named season 15 champ. "I came here to gain back my life, and I did exactly that. I've found that proud, confident girl that has so much respect for herself."
