Time to break fast

So my strategy didn't work.  After a few days, I ended up weighing myself and I was still stuck in the 187's.  So I decided to eat like shit for a couple days.  Now I'm going to attempt a 24-48 hour fast.  I'm hoping my body will respond well.  I hope I can successfully complete a 48 fast.  Then I'll return to consuming 500 calories a day.  I've been in this situation before.  I just need a breakthrough weightloss and I'm back in the saddle.  I'm not giving up.  I've come too far to give up.  150 is still my goal.
