According to the American College of Sports Medicine, lean muscle
mass may decrease by nearly 50 percent between the age of 20
and 90. If you do nothing to maintain muscle mass, you could be
losing muscle and increasing fat. It is also important to know your
muscle mass percentage during weight reduction. At rest, the body
burns approximately 110 additional calories for each kilo of muscle
gained. Benefits of gaining muscle mass include:
• Reversing the decline in strength, bone density, and muscle
mass associated with aging
• Maintenance of flexible joints
• Guided weight reduction when combined with a healthy diet
