Chalene Extreme and calories?

Options
I just started Chalean and trying to figure out how high up I should go on calories?

I'm at my current weight of 116-117 and got there with cardio and dropping to 1200 calories. I know that I should go up in calories cause I'll feel more hungry after these workouts but not sure how high to go up? Thinking 1500 maybe?

Any thoughts would be great! Thx.
