Study
Preserving Muscle During Weight Loss in Older Adults
Incretin-based therapies can lead to muscle loss during weight reduction; exercise and adequate protein intake help preserve muscle strength.
Heart Health
Summary
In plain language
Researchers have discovered that while incretin-based therapies used for weight loss in older adults can lead to a reduction in muscle mass, maintaining muscle is crucial for long-term health benefits. The study showed that 25–40% of weight loss from these therapies may come from losing lean muscle. To counteract this, strategies such as regular exercise, proper protein intake, and potentially new treatments can help maintain muscle mass. This is important because muscle health is key to cardiovascular health and overall well-being. Seniors using these therapies might want to discuss muscle-preserving strategies with their healthcare providers.
