Operating at a calorie deficiency as you describe is counter-productive, as you are forcing your body into calorie conservation (starvation) mode while trying to build strength and conditioning.
Eat all you want, your body will take up the calories it needs, and discard the rest.
If, and this is the big if, your endocrine system (read: insulin response) is not compromised by eating fast carbs and sugar.
Ever wonder how cavemen ate, 50 thousand years ago? They ate what they could kill, or forage. Their staple was animal products, not grains or sugars, as these were never in abundant supply. Modern man is adopted to this diet, genetically, and only recently, in geolithic time, has any other diet but this been available.

I don't think human physiology has a reliable way to simply expel excess calories in real time.
Urine should be free of carbohydrates. Glucose expelled into urine = Diabetes.
Protein in urine is similarly considered to be pathologic and an early sign of kidney failure.
AFAIK, there isn't a smart or variable regulation of nutrient absorption at the level of the small intestine. The gut just cleaves whatever it can into it's most basic building blocks of carbs/protein/fats with enzymes and dumps the smallest nutrient molecules into the bloodstream for other metabolic systems to sort out later.
Fecal waste from the large intestine compromises mostly undigestible components of food like dietary fibre. I don’t believe calories can be excreted this way.
