I'll assume that you are being serious, which I would hope that you are smart enough to NOT be serious about this. If you are serious and do consider yourself to be intelligent, are you a narcissist that is starving for attention?
How much research have you done into the Biggest Loser? What makes you think they would pick you to be on their show? Wouldn't you think that they would want some history of a weight issue? Do you think they would risk their reputation by taking on someone foolish enough gain weight on purpose just to be on their show?
So that leads me to believe that either you are:
1) a troll
3) a narcissist
So which is it?
