I WANNA LOSE 40 POUNDS IN A MONTH! HELP!?

okay please, you will have no chance of getting best answer if you say "thats unhealthy" or anything related to that. I want to look pretty for school coming soon, and impress this boy :P i know i should be happy with my body and i shouldnt just do this for some guy, but i also want to do it for my health. Anyway, what can i do? should i starve myself, work out a lot, eat only 3 portions a day? lol IDC ill do anything (and yes, i know i sound like a freak right now) but yea. im 5'6 but i dont feel comfortable sharing my weight. im not really heavy, i just need to shed some pounds. k thanks! :)
