Chicken doesn't build muscle or burn fat. It is a high protein, low fat food. If you are working hard the protein helps your muscles recover and repair itself. If you are overloading the muscles, they will grow larger and they need protein to do that but the protein by itself doesn't do this.
Chicken doesn't burn fat at all. It is a low fat and no sugar food so it helps you not add fat but it doesn't "burn" any fat. To lose fat you must burn more calories than you take in. Its very simple but true. Theoretically, a pound of fat is 3500 calories. So if you could burn an extra 500 calories each day while eating 500 calories less each day then you would lose 2 pounds per week.
These numbers are theoretical but they are a good foundation to base your diet and exercise program on.
