Sarcopenia: Why Muscle Disappears With Age—and What You Can Do
Sarcopenia is the age-related loss of muscle strength and muscle mass. It can make everyday activities—standing from a chair, climbing stairs, carrying groceries, or walking—more difficult and can increase the risk of falls and loss of independence.

What causes muscle loss?
Several factors can contribute:
Aging: Muscle mass and strength naturally decline with age.
Inactivity: Spending long periods sitting or being bedridden accelerates muscle loss.
Too little protein or overall nutrition: Muscles need adequate protein and calories to maintain and repair tissue.
Chronic illnesses: Conditions such as diabetes, obesity, and other chronic diseases can contribute.
Hormonal changes: Age-related changes in anabolic hormones can affect muscle maintenance.
Inflammation and other biological changes: Aging can alter how effectively muscles respond to exercise and dietary protein.

The most effective solution: resistance exercise
Strength training is the cornerstone of preventing and treating sarcopenia. It doesn’t necessarily require a gym. Squats or sit-to-stands, resistance bands, light weights, wall push-ups, and other exercises can be adapted to your abilities.

A practical starting point is muscle-strengthening exercise at least twice a week, working the major muscle groups and gradually increasing resistance as you become stronger.

Don’t forget protein
Include protein-rich foods throughout the day, such as:
Eggs, poultry, fish, and lean meat
Milk, yogurt, and other dairy foods
Beans, lentils, and other legumes
Nuts and seeds
Tofu and other soy foods
For people with sarcopenia, some clinical recommendations suggest roughly 1.0–1.2 g of protein per kilogram of body weight per day, with individualized targets depending on health and nutritional status.

If you have kidney disease or another condition requiring protein restriction, don’t increase protein substantially without discussing it with your healthcare professional.
A simple muscle-preserving routine
Think strength + protein + movement:
Perform resistance exercises about 2 days per week.
Walk or perform other appropriate aerobic activity regularly.
Include a good protein source with meals.
Add balance exercises to help reduce fall risk.
Progress gradually rather than attempting heavy weights immediately.
If you’re experiencing rapid or unexplained muscle loss, significant weakness, repeated falls, or difficulty getting out of a chair, ask a healthcare professional for an assessment. Sarcopenia can be evaluated using measures such as grip strength, walking ability, and muscle mass.

Bottom line: Muscle loss isn’t simply something you have to accept with aging. Progressive resistance exercise plus adequate nutrition—especially protein—can substantially help preserve strength, mobility, and independence.
