Why Protein Matters More After 35
As we age, our bodies naturally lose muscle mass—a process called sarcopenia. After age 35, protein becomes especially important to help preserve lean muscle, maintain metabolism, and keep energy steady throughout the day. Protein also plays a key role in satiety, so it helps prevent energy crashes and overeating. In short: protein is more than a “fitness nutrient”—it’s a critical foundation for healthy aging.
