Weight/Resistance Training/Sarcopenia

What Is Sarcopenia?

Sarcopenia is the gradual loss of muscle mass, strength, and physical function that occurs with aging. Beginning as early as our 30s and 40s, adults naturally start to lose muscle mass over time, with the rate of loss accelerating later in life, particularly after menopause.

Muscle plays an important role in overall health. It helps maintain strength, mobility, balance, metabolism, bone health, and independence as we age. Loss of muscle mass can increase the risk of falls, fractures, frailty, and reduced quality of life.

Can Weight Loss Cause Muscle Loss?

Yes. Whenever weight loss occurs—whether through lifestyle changes, medications, or bariatric surgery—a portion of the weight lost can come from lean muscle mass as well as body fat.

Newer weight loss medications such as semaglutide (Wegovy®, Ozempic®) and tirzepatide (Zepbound®, Mounjaro®) can result in significant weight loss. While this can lead to major improvements in health, rapid weight loss may also increase the risk of losing muscle mass if steps are not taken to preserve it.

The goal is not simply to lose weight—it is to lose excess body fat while maintaining as much healthy muscle as possible.

Why Is Muscle So Important?

Maintaining muscle mass helps:

✔ Support a healthy metabolism

✔ Improve strength and physical function

✔ Protect bone health and reduce fracture risk

✔ Improve balance and reduce falls

✔ Enhance insulin sensitivity and blood sugar control

✔ Support healthy aging and long-term independence

The Importance of Resistance Training

Resistance training (strength training) is one of the most effective ways to preserve and build muscle during weight loss.

Examples include:

Weight lifting
Resistance bands
Bodyweight exercises (squats, lunges, push-ups)
Pilates and strength-focused exercise programs
Functional strength training

Current recommendations suggest incorporating resistance training at least 2–3 times per week, targeting all major muscle groups.

Protein Matters Too

Adequate protein intake is another important strategy for maintaining muscle during weight loss.

Protein provides the building blocks needed to repair and maintain muscle tissue. Many individuals undergoing medical weight loss benefit from increasing their protein intake while reducing overall calories. Your individualized nutrition plan should be discussed with your healthcare provider or registered dietitian.

The Goal: Healthy Body Composition

Successful weight management is about more than the number on the scale. The ideal outcome is improved body composition—losing excess body fat while preserving or even building muscle mass.

For this reason, medical weight management should always include:

• Adequate protein intake
• Regular resistance training
• Physical activity
• Healthy sleep habits
• Ongoing medical monitoring

At the Peri/Menopause and Sexual Wellness Clinic, we focus on helping patients achieve meaningful, sustainable weight loss while protecting their long-term health, strength, and quality of life.
