It depends on how lean you are right now. If you're as lean as I am, I would say that losing more than 4-5 pounds of fat in that period would be difficult, if you intend to maintain 100% of your lean mass. If you can't see your abs, then it should be easier to lose more.
Have you considered using something like clenbuterol or albuterol to assist the fat loss? That could help preserve muscle mass while cutting.
