Calorie change up for P90X?

So I'm about to start doing the P90X program today, and in the past 4 months I've been eating around 1200 calories a day. Although I have been losing weight, I was wondering if I should kick it up to 1300 due to the intensity of the P90X workout.
What do you think?

Yikes. Those are both way too low... unless all you do is sleep all day. 

The P90X program recommends 1700 calories, on the low end! It's intense, and those extra calories will be put to good use. I say you should aim for at least 1500 calories per day.  

Or try consuming 1500-1700 on the days that you work out, and 1300-1400 on your rest days (this may be a bit more mentally easy for you)

When starting any intense program, it's not a good idea to starve yourself!! The calories that you eat right now is even too low for most people on a regular basis.
