You are eating too little. You will hit a wall and then loss in body fat will stop.
I could see eating like that if you were untrained and carrying more body fat, but if those stats are real, you have quite a bit of muscle that you are NOT feeding....so it will NOT stick around.
You will start losing more muscle than fat.
I would add at least 500 cals or more and approach this differently. Follow the bodybuilders.
