Gale, how do you feel at those levels? What were you eating calorie/carb wise before you started working out like this? Has it changed? Do you feel hungrier?

If you maintain at 2500 calories then eating 300-500 below that consistently with the exercise will result in a deficit - assuming everything is working properly metabolism wise. You've been maintaining for a while now - did you keep track of calories/carbs/protein that whole time? If so you'll find playing with the numbers now eaiser.
