Eat more and train more, simplest method. 4,500 to 5,000 calories a day, I am stable weight and can produce six pack to order with no difficulty.
I am about 15% too, and to be fair I find that this is ideal to maintain sensible all round ability. If you start going more toward aesthetic, especially regarding body fat, there is the potential for you not to have the energy you want to put into your training. It can of course be done and many do manage, but I doubt they quadruple their intake one day a week.
If you need a treat have one thing a day that you really enjoy, as a reward.
There is something I learned about known as the starvation system which means what you are proposing could easily make your aim impossible and your lifestyle dangerous.
If you consume too little food your body will cut metabolism etc. to avoid wastage and conserve energy, you require to live. If this goes to a point where the body decides you are in starvation it will start shutting down non-essential systems, leaving you less healthy and open to infections.
If you suddenly load up on calories after starvation, your body will grab everything it can and store more than previous in case of future starvation episodes when this will be needed. A smart move on the bodies part and why yoyo dieting results in overall increase in weight and body fat.
