I'm not sure where the misconception is coming from about calories. A calorie is a calorie is a calorie. Different types of calories serve your body in different ways.

A pound of fat is 3500 (estimated) calories to gain or lose. The type of calorie is of no consequence.

So, to lose a pound a week, eat 3500 fewer protein calories, or 3500 fewer carb calories or 3500 fewer fat calories, etc. It doesn't really matter, but it's best to cut across the board rather than cut one segment of your diet.
