Skeletal muscles are your body's natural fat burners, according to exercise physiologist William McArdle in "Exercise Physiology: Energy, Nutrition, and Human Performance." Muscles constantly use fat and carbohydrates to keep you warm and provide you with energy for movement.

One pound of muscle burns about 6.5 calories per hour. Muscles burn 5.5 times more calories than fat tissues, which burn about 1.2 calories per pound per hour.
You can increase your muscle mass by strength training, which stimulates your body to develop thicker muscle fibers. You can use various methods to increase muscle size, such as weight training, calisthenics, sprinting and jumping.
Basal Metabolic Rate
Your basal metabolic rate is the amount of energy you expend, or calories you burn, when you are at rest. The more muscles you have, the more calories you burn when you exercise and rest.
