Summary
Experts warn that muscle loss is a natural part of aging, exacerbated by lifestyle changes and hormonal shifts. Jacob Zemer, a fitness coach, emphasizes the importance of strength training and protein intake to maintain muscle mass. He notes that GLP-1 medications, used for weight loss, can accelerate muscle loss if not balanced with exercise and proper nutrition. The U.S. Physical Activity Guidelines recommend strength training at least twice a week. Zemer also highlights the role of sleep and consistent movement in preserving muscle as people age.

GLP-1 Medications and Muscle Loss
GLP-1 medications, which are increasingly used for weight loss, have been linked to a loss of lean muscle, especially during rapid weight loss. Experts warn that muscle loss is a natural part of aging, but the use of these drugs can accelerate the process.
Lifestyle Changes and Muscle Loss
As people age, lifestyle changes such as reduced physical activity and shifts in career and family responsibilities can lead to a more sedentary lifestyle. This decrease in activity lowers metabolism and contributes to muscle loss, according to Jacob Zemer, a fitness coach.
Hormonal Changes and Muscle Loss
As people approach their 40s, hormone levels change for both men and women. These changes can lead to a shift in how the body uses calories, with more being stored as fat and less used for protein and muscle building, Zemer noted.
Protein Intake and Muscle Maintenance
Protein is essential for muscle protein synthesis, the body’s process of repairing and building muscle. Zemer recommends a protein intake of 0.8 to 1 gram per pound of body weight for those who regularly strength-train. However, sedentary individuals generally do not need to be overly concerned about protein intake.
Exercise and Sleep for Muscle Health
Regular strength training and adequate sleep are crucial for maintaining muscle mass. Zemer emphasizes that even short workouts can help preserve muscle, and that sleep deprivation can lead to rapid muscle loss. Consistent movement, even without structured workouts, is important for slowing age-related muscle loss.
