Yes: get liposuction, or amputate a limb.

Seriously, though, it's impossible. Your body won't do it. Remember: to lose a pound of fat you have to burn off 3200 calories above and beyond what you consume. That's presuming a *normal* metabolism. If you crash diet, your metabolism gets way below normal. Plus, the more times you do this, the slower you permanantly make your metabolism.

You can try it, but if you lose 20 lbs in ten days without surgical intervention, I'll eat my computer.

So lemme guess: you have a big party or trip next Friday. It's too late to be sweating over weight, just try to have fun, anyway.
