Does Mounjaro or Wegovy cause muscle loss? What the research shows

Both Mounjaro and Wegovy help you lose weight mainly by reducing body fat, but you can lose some muscle during rapid weight loss, as you would with any diet. Clinical studies show that most people keep the majority of their muscle if they eat enough protein and do regular strength or resistance exercise. For the best results, focus on protein-rich meals and keep active while using these medications.
