To clarify the math.
If you hit your goal exactly, with 0 calories left over, that means you have a 500 calorie deficit for the day. It's already built into your 1 pound per week goal. 1 pound per week = 7 days * 500 calorie deficit per day = 3,500 kcal weekly deficit, the amount of calories in a pound of fat.
