Sarcopenia

Definition

Progressive loss of skeletal muscle mass and function. Rapid weight loss — whether from bariatric surgery, GLP-1 therapy, or calorie restriction — accelerates muscle loss alongside fat loss. Mitigation focuses on adequate dietary protein (1.0-1.6 g/kg/day) and resistance training during active weight-loss phases.
