Does a calorie deficit amount to a loss in body fat (abdominal area)?

I am around 10% body fat which is relatively low...as an 18 year male. I eat a pretty healthy diet, at least in terms of maintaining a low fat percentage. Typically low in carbs, high in protein, high in figer, and average in fat (but typically good fats). However, I can not seem to lose the fat around my abdominal/torso area of the body. Virtually no other places on my body have fat, so this would be regarded as "stubborn fat." I have somewhat of an aversion to cardio exercise (running, etc). However, I have no problem walking 3 hours a day on the treadmill, burning 700 calories or so (which I do not currently do). So the real question is, will creating a calorie deficit equate to a loss of more body fat and ultimately a very low percentage? Does the heart HAVE to be at a max rate for stubborn fat to be lost as opposed to the body being in starvation mode and burning muscle tissue? Again, the goal really isn't to put on lots of lean tissue here, it is simply to lower my body fat percentage from 10% to 6-7%...can it be done without hard core cardio, considering that a healthy diet has hit a plateua at this point?Much appreciated.

How do you know your 10%? Search up george st pierre and hes about 8 or 9% bodyfat. If you make a 1000 calorie deficit a day you would lose 2 pounds of fat a week. Also why do you have a low carb diet? Also its a myth that you need all that protein you only need about 70 grams of protein a day. Your diet should be 60% complex carbs 30% protein and 10% fat But that's a perfect diet. Also why are you walking why not run to work your heart more and increase your performance
