In the article "Coffee May Help With Muscle Mass As You Age, New Study Says," Scott Keatley, RD, co-owner of Keatley Medical Nutrition Therapy, contributes his expert opinion on the study linking daily coffee consumption with higher muscle mass. He emphasizes that while the research shows a strong association between coffee and improved skeletal muscle mass, it does not definitively prove that coffee alone preserves muscle as people age. Keatley attributes the potential benefits to the anti-inflammatory and antioxidant properties of caffeine, which may help prevent muscle degradation. However, he cautions against starting a coffee habit solely for muscle mass improvement and recommends focusing on a balanced diet with lean proteins and resistance training as more proven methods for maintaining muscle mass.
