Hmm.

HIIT is a good start, as are compound lifts (as I am sure you know), and your sedentary BMR is likely somewhere around 2200-2400 calories. A good rule of thumb is to eat 1g per pound of bodyweight per day, so that's 410 calories there if you were eating straight protein (obviously not possible).

You probably want to be at or around 2600-3000 calories per day while you are doing HIIT and an intense compound lift-centric workout schedule. The most important part is to eat multiple small meals throughout the day - ideally 4-6 meals that are appropriately timed (PWO shakes, a good breakfast, small snack before bed, etc).
