Macros and Fitbit

just a little advice! I want to lose 10lb especially round my belly I'm male 5'11 33 years old and have set mfp to sedentary and to lose 2lb per week, I've also attached a Fitbit to my account! I'm confident enough to stay under my calorie goal easy! But I'm worried about macros I'm always high on fat and carbs! Does this really matter??
