Treating all calories the same ignores the fact that the body does different things with Carbs, Fats, and Proteins. Proteins help build muscle which raises a person's resting metabolic rate. A diet that is deficient in proteins will result in muscle loss and will lower metabolic rate. The scale only tells half the story. 200 lbs of lean muscle burns much more calories than 200 lbs of fat. What you eat directly contributes to this composition and therefore impacts your ability to burn calories.
