I know its over simplified but so long as you expel more than you eat.
Running an hour in the morning should do quite a bit, since you not only burn calories during the hour but your metabolism is heightened the rest of the day.
Tochange up my cutting diet, and get myself out of a stall in both the bf% and weights, I actually increased my calories above maintance but did more cardio ect... It worked started to lose again, and my weights actually improved w/ all the added protein intake, though I couldn't keep it up I quickly burnt myself out.
I was eating alot though, so if you don't go crazy it may be possible, other contributing things however are what your curent bf% is since as you get lower it gets harder to remove the fat but is much easier at higher lvls its one of the reasons there seems to be so many sticking points in our cutting diets where all of a sudden we stop losing.
