What is muscle loss?

Muscle loss, also known as muscle atrophy, occurs when muscle cells shrink or degrade as a result of aging, illness, or lack of physical activity. This leads to a loss of muscle mass, strength, and function over time.

Some key points about muscle loss include:

• It can begin as early as age 30. Most adults lose about 3-5% of their muscle mass per decade after 30.
• Lack of exercise accelerates muscle loss. Without strength training, most adults lose 30-50% of their muscle mass between ages 50-80.
• Diseases like cancer, heart failure, arthritis, and diabetes are linked to rapid muscle loss. This often stems from increased inflammation or hormonal changes.
• Muscle loss leads to fatigue, weakness, mobility issues, increased injury risk, and reduced quality of life. It also slows metabolism.
• Strength training with resistance bands, weights, or bodyweight exercises can help rebuild and maintain muscle mass at any age. Aim for 2-3 sessions per week.
• Getting enough protein through food or supplements assists muscle growth and recovery from exercise. Most adults need 0.36-0.45g of protein per pound of body weight daily.
• Proper sleep, stress management, and treatment of underlying illnesses also prevent excess muscle loss over time.

In summary, muscle atrophy is the wasting or loss of muscle tissue. It gradually decreases strength and mobility, but strength training and protein can help counteract the loss. Seeking treatment for illnesses that inflame or break down muscle tissue may also slow muscle wasting.
