oh dude, you just asked the unanswerable. Okay I'll get the standard answers out of the way first. Look in the article library on this site for great diets. You can drop your caloric intake as low as you can tolerate.
Okay that out of the way, here is my personal advice. First, I'm not a liscensed anything and a bit chubby myself.
You can do as much road work and shadowboxing as you can take. Drop your caloric intake only a little. Keep the carbs low and protein high. Drink Surge or Gatorade or something else carbby when you get ready to go to the gym for your big workout. then have some more carbs right after, try to not consume many carbs the rest of the day.
If your committed you'll lose the weight, of course, if your committed you'll knock off the stupid crap that gets you sent away.
