As we age, muscle mass gradually decreases, a process termed sarcopenia. This can hijack a person’s independence and confidence, making even simple daily tasks, such as lifting groceries or opening a jar, difficult. Losing muscle mass can also increase one’s risk of falling, a major cause of disability.
Sarcopenia develops around the fourth or fifth decade of life, although its rate of acceleration varies due to multiple factors, such as chronic illness, inactivity, or poor nutrition, particularly inadequate protein or calorie intake.
