Needing to Lose Weight Quick

I just realized it is a few more weeks until I will be attending a very important event. Time sure does fly these days. I was thinking I need to figure out some diets for quick weight loss. I haven't got time to spare if I plan on being a certain weight by the time for this important social event. I have had it on my calendar for months, so you would have thought I wouldn't have waited until the last minute. But just as always, I scrabble around a panic when it comes down to the last minute.
