When in a calorie deficit does it depend on genetics, diet and/or exercise how your body prioritizes the source of fuel it uses and to what ratio and order it uses?

So, let's say you are in a calorie deficit of 500 calories per day and you are at a 15% body fat level. What does it depend on what your body starts using among the different available sources of fuel (body fat, dietary fat, dietary protein, lean muscle tissue, dietary carbs, glycogen stores, etc) to keep you alive?

Does it depend on how, when and what you eat; how, when, for how long and what you exercise, your genetics?

Curious to hear your opinions.
