Losing Weight Fast

[UCF THAYER]

I know there have been lots of "Losing Weight" threads, so i apologize, but i think my question is unique enough for a new thread.

Me and my friend(similar in size and weight) have made a $1000 bet on who will lose the most weight by New Years. I am 5'9 and 200 lb's.
What is the fastest way to lose weight, solely for winning the bet?
I don't care if i'm "just going to gain it all back - and then some", I just want to lose the most possible weight i can in the next 40 days.

What should i do?

Excercise a whole lot?
Don't eat any bread(carbs)?
Live off water and vitamins?
Eat alot of Fiber?
Any special pills?

I appreciate any feedback.
