The Importance of Protein Intake for Building Lean Muscle Mass

Protein is often called the body’s “building block” for good reason: it helps repair and grow your muscles after exercise. When you exercise—especially with weights—you create tiny micro-tears in your muscle fibers. Protein helps repair these micro-tears, leading to stronger, larger muscles over time.

Why Protein Matters for Muscle Growth

Every time you exercise, particularly with strength training, your muscles undergo stress. Protein provides your body with the amino acids it needs to repair these stressed muscles, making them stronger and reducing recovery time. Without sufficient protein, your progress in muscle growth could stall.

How Much Protein Do You Really Need?

Protein needs vary based on your activity level:

• Average adults: 0.8 grams per kilogram (0.36 grams per pound).
• Active individuals (for muscle growth): 1.2–2.0 grams per kilogram (0.5–0.9 grams per pound).
• Older adults (65+): At least 1.2 grams per kilogram to prevent muscle loss.

Common Myths About Protein Intake

• Myth 1: “More protein is always better.”
  Reality: Excessive protein beyond your body’s needs doesn’t significantly enhance muscle growth.
• Myth 2: “You need protein supplements to build muscle.”
  Reality: Whole foods can adequately meet your protein needs.
• Myth 3: “High-protein diets damage your kidneys.”
  Reality: Unless you have existing kidney conditions, high-protein diets are generally safe.
