Semaglutide has transformed the way medical professionals approach weight management. However, a recent study presented at ENDO 2025 has raised a significant concern: patients, particularly older women, may experience loss of lean muscle mass if protein intake is too low during treatment.
While weight loss can improve many aspects of health, losing muscle instead of fat can lead to fatigue, reduced strength, slower metabolism, and greater difficulty maintaining results. For older adults, this effect can be even more pronounced, impacting overall mobility and long-term health.
The latest findings suggest that adequate protein intake and regular resistance training can significantly reduce the risk of muscle loss during semaglutide therapy. With the right medical supervision, patients can achieve meaningful fat loss while maintaining a healthy, active body composition.
ENDO 2025 Findings: Why Protein Intake Matters
At the Endocrine Society’s ENDO 2025 conference, researchers followed 40 adults over a 3-month period who received semaglutide, while 17 followed a diet and lifestyle plan.
Key observations from the study included:
- Participants on semaglutide experienced greater overall weight loss compared to those in the diet group; however, part of that loss was attributed to lean muscle.
- Older adults and women with lower protein intake had higher rates of muscle reduction.
- Individuals who lost more lean mass also showed smaller improvements in blood sugar control (HbA1c).
These findings highlight the importance of providing targeted nutritional and exercise support during GLP-1-based weight loss programs. Other research published in the Journal of the Endocrine Society also supports this, noting that calorie restriction often reduces both fat and muscle unless protein and strength training are prioritized.
Strategies to Prevent Muscle Loss During Semaglutide Therapy
A comprehensive plan can help patients safely benefit from semaglutide while minimizing the risk of muscle loss. Evidence from multiple studies suggests the following approaches are most effective:
1. Increase Protein Intake
Maintaining adequate protein intake helps protect lean mass during weight loss. Experts recommend 1.2 to 1.6 grams of protein per kilogram of body weight daily, based on individual needs and medical history.
2. Add Resistance or Strength Training
Combining semaglutide therapy with strength or resistance exercises signals the body to preserve muscle tissue while reducing fat. This combination supports a stronger metabolism and long-term results.
3. Monitor Body Composition
Tracking body composition using scans or bioimpedance analysis can help patients and healthcare providers determine whether weight loss primarily results from fat or muscle loss. Regular assessments enable timely adjustments to nutrition or exercise plans.
4. Personalize Nutrition for Higher-Risk Groups
Older women are especially vulnerable to lean mass loss on semaglutide. Medical providers should develop individualized plans that prioritize protein intake and include safe, progressive strength exercises.
Who Is Most at Risk for Muscle Loss?
Understanding your risk factors can help you take proactive steps to protect your muscle mass during weight loss:
Older Adults: Age-related muscle loss (sarcopenia) can be accelerated during rapid weight loss, making protein intake and strength training even more critical for this population.
Women: Female patients, particularly postmenopausal women, showed higher rates of muscle loss in the ENDO 2025 study when protein intake was inadequate.
Individuals with Low Baseline Protein Intake: Those who don’t regularly consume adequate protein are at higher risk and may need significant dietary adjustments before starting semaglutide therapy.
Sedentary Patients: People who are not physically active are more likely to lose muscle during weight loss, as the body has no signal to preserve that tissue.
If you fall into any of these categories, working closely with a medical provider to optimize your nutrition and exercise plan is essential for protecting your muscle mass while achieving your weight loss goals.
