Yeah, mine is around 1,100-1,300 max. I exercise/lift at least every other day and I have an active job. But my short female body will gain weight at and above 1,300.  My 1,300 max is if I did a heavy leg day with a jog and sprints. Or a heavy stairmaster day, with jogging sets in-between, then my leg day routine.  I agree, 2,000 is a bit excessive, however if you are in an academy, training hard every day, a lot of weighted cardio or weighted HIIT programs, or even a 8-10hr construction day will need that many calories.  Calories are fuel for our body! If we don't need it, then don't eat it.
