the more muscle mass you have, the more energy it takes to burn calories, therefore, you burn more fat and calories. yes, the body does need calories, but it also needs protein which helps build muscles and in turn, burning more calories. try googling it to find out more info.
The only time that you need to be in a caloric surplus to add muscle is when you are at low fat percentages. However, you will need a surplus of NUTRIENTS (especially carbs and protein) to add muscle.
For example, someone who weighs 200 lbs and has 20% body fat will have a lean mass of 160 lbs and a resting metabolic rate of around 1950 calories per day.
If he eats 250 grams of carbs, 130 grams of protein, and 40 grams of fat per day, he will get adequate protein and carbohydrates while only consuming 1880 calories per day.
This will put him in a caloric deficit even when you do not factor in the calories that he will be burning from exercise. If he is lifting weights, he will be gaining muscle while slowly losing fat due to the caloric deficit.
Here is an article about muscle growth and a calorie estimator for gaining muscle while losing fat.http://www.spartafit.com/main/muscle%20g…http://www.spartafit.com/main/calories%2…
Also, the increased muscle from working out will burn more calories.
