We begin to lose muscle mass after our 30s due to a combination of factors related to aging and lifestyle changes. Here’s why:
Decline in Hormones: Testosterone and growth hormone levels naturally decrease as we age, which affects muscle growth and repair. These hormones play a key role in maintaining muscle mass.
Reduced Physical Activity: As people age, they tend to become less physically active, leading to muscle atrophy (wasting) due to disuse. Without regular exercise, particularly strength training, muscles shrink over time.
Slower Muscle Protein Synthesis: As we age, the body’s ability to repair and build muscle after exercise declines, leading to slower muscle growth and recovery.
Changes in Diet: Often, dietary patterns change with age, and insufficient protein intake can exacerbate muscle loss. Protein is essential for muscle maintenance and growth.
Regular strength training, adequate protein intake, and staying active can help slow down muscle loss and improve overall strength and mobility as we age.
