Try and replace regular potatoes with sweet potatoes. There is more fiber and minerals such as Potassium and calcium in sweet potatoes.
If your schedule allows try for more sleep too as this will aid in recovery.
Lastly, how do you feel about barbell compound movements such as bench, deadlift and squats? Do you have access and are there any injuries that would prevent you from doing these movements. I see a lot of isolation work but compound movements will work more muscle groups simultaneously therefore burning more calories. You can run a 5x5 stronglifts or Wendlers 5/3/1 program while still incorporating a couple of isolation movements.
