Well as somebody who has done a lot of research on hormone stuff, I can tell you that starvation drops your testosterone levels into the garbage. You'll lose a lot more doing that, if you aren't super careful with it. And also the vast majority of what you loose on a super quick cut like that is water weight, so it's kind of pointless.
Here's what I would recommend, take a break from the scale for a bit, focus on other measures of improvement (like gym capacity and what-not) keep your diet consistent and then weigh yourself after you're going to be closer to where you want to be. That way the temptation isn't there.
