Several factors can contribute to age-related muscle loss.
1. Aging
As we age, the body becomes less efficient at building new muscle proteins. Hormonal changes and changes in the nervous system can also affect muscle maintenance.
This means that muscles may gradually become smaller and weaker unless they are regularly stimulated.
2. Lack of Physical Activity
A sedentary lifestyle is one of the biggest contributors to muscle loss. Muscles need regular use to remain strong.
Long periods of sitting, inactivity, or bed rest can accelerate muscle loss, particularly in older adults.
3. Not Getting Enough Protein
Protein provides the amino acids needed to repair and build muscle tissue. Older adults may need to pay particular attention to getting enough high-quality protein throughout the day.
Good sources include:
- Eggs
- Fish
- Chicken and other lean meats
- Milk and yogurt
- Cheese
- Beans and lentils
- Nuts and seeds
Rather than relying on one large protein-rich meal, including a source of protein in several meals can be a practical approach.
4. Poor Nutrition
Insufficient calories or a diet lacking important nutrients can contribute to muscle loss. Severe or prolonged dieting may cause the body to break down muscle tissue for energy.
A balanced diet containing adequate protein, fruits, vegetables, whole grains, and healthy fats can support overall muscle health.
5. Chronic Illness
Certain long-term health conditions can increase the risk of muscle loss. Inflammation, reduced activity, poor appetite, and changes in metabolism may all play a role.
For this reason, significant or rapidly progressing muscle weakness should be discussed with a healthcare professional.
