Are we giving too much weight to lean mass loss?

Emerging evidence suggests that muscle quality may be a more reliable indicator of functional capacity and longevity than absolute muscle mass.

• The balance between fat mass and lean mass is crucial for health outcomes.
• Excess fat mass is linked to chronic diseases and reduced lifespan.
• Preserving lean mass is important for reducing fall risk and maintaining independence.
• Incretin-based weight loss therapies are effective in reducing body weight but may lead to lean mass loss.
• These therapies could potentially improve muscle quality despite the loss of lean mass.
