MFP&Insanity

Hi all,
Im doing insanity and trying to use the myfitnesspal app at the same time. Im getting confused with how I should log it. Insanity has you use the harris benedict formula to calculate your calorie intake. I did mine and it is around 2200 calories per day... With a 500 deficit its taking me down to 1700 a day. Should I just make goal calorie on the app 1700 and change the calorie fat and protein percentages to what insanity requires? If I do this then I don't have to add my workouts.(calorie wise). Im not sure how to do it? this whole net calorie thing on the app is confusing me because I know with working out im supposed to have 1700-2200 calories per day. Thanks!
