The Science
This beef is excellent for muscle building due to its high protein content (21.2g per 100g, +42% DV), which provides essential amino acids for muscle protein synthesis. It also supplies zinc (+35% DV) and phosphorus (+15% DV), which support testosterone production and cellular energy metabolism, respectively, both critical for muscle growth and recovery. The moderate fat content (+11% DV) provides additional calories to support a caloric surplus needed for muscle gain.
Recommendation
Include this lean beef in your diet as a primary protein source, aiming for 1.6-2.2g of protein per kg of body weight daily, and pair it with resistance training for optimal muscle growth.
