No supporting scientific documentation is available for human "entropy." It is assumed that the question was meant to be worded instead as "atrophy." According to Healthline, muscular atrophy can be treated with regular exercise and balanced nutrition.
Muscular atrophy is caused by a lack of muscle use and movement. According to HealthGrades, individuals who lead sedentary lifestyles are most likely to develop a loss of muscle tissue. Other causes of muscular atrophy are injuries such as broken bones, and illnesses which may cause an individual to lose range of movement, such as osteoarthritis, Guillain-Barre syndrome, Lou Gehrig's disease or paralysis. Muscular atrophy develops over time. It's a common occurrence in the elderly, as activity levels and range of motion naturally decrease with age. Muscular atrophy can also be caused by malnutrition
According to Healthline, muscular atrophy is usually easy to reverse with regular weight-bearing exercises and physical therapy. Healthline recommends scheduling an appointment to see a physician if muscular atrophy is suspected. Doctors use blood tests, magnetic resonance imaging, muscle biopsies and X-rays to identify the cause or causes of the muscle degeneration and construct an effective plan to improve muscle density and functioning. In the most extreme cases, surgery may be required.
