Do a shit load of cardio and drop calories down to less than 10X calories per pound and cycle on and off with a major refeed (reserve a 'cheat' day that requires tons of carbohydrates and low in fats), and presto, you should lose some fat albeit some muscle too. Hey, that's the price you payy for trying to lose a shit load of fat in the last minute.
So here's a basic schedule..
Day 1-3: Eat 10X bw, ISO or somewhat of a low carb diet, eat 6-10g of Fish Oil
Day 4: Cheat day consisting of a weight training workout in the earlier part of the day followed by a massive supercompensation. Basically, eat a shit load of carbs in the form of mainly glucose (and also sucrose so that you can recarb the liver with the fructose from sugar so to speak to get yourself in the anabolic state along with indirectly raising the hormone leptin).
You should eat around 30% above your maintenence calories on this day.
Repeat
It works, of course, it's nowhere near as good as using DNP, but at least you should lose a good amount of fat.
The best strategy overall if you did have more time is to SEVERAL days of hypocaloric dieting (eating between 10-12Xbw) followed by a day or two or refeed (depending on your bodyfat levels and how long you have been dieting before)
