203.2. - trying to lose 15lbs in a month

I've been floundering a bit since the BJJ tourney, not sure if I wanted to bulk up or lose weight.  So, I've decided to try to drop another 15 lbs.  that would get me down a weight class and make me able to cut a bit of weight to then drop another weight class for competitions.  

Then I will have lost most of the weight I have to lose and can start slowly adding muscle.
