how much protein and calories

Options
I'm looking for help on how much protein and calories to eat. I'm 140 pounds with 17% body fat, I'm currently doing insanity 6 days and also running 3 times a week for 3-4 miles. I been seeing results but feel tried and was told that I'm not eating enough which is causing my muscle to break down. Please can someone give me some info on what to do.

    Did you doing that BMR calculation? I know that it's in the meal plan book in Insanity to calculate how many calories you eat.....?

    17% body fat? You should be pretty ripped at 17%.

    Most body builders say to aim for 1 to 2 grams of protein per pound of lean body mass. You should have your calories set at near maintenance at this point to preserve muscle mass.
