Why Protein Matters

Protein is essential for building and repairing muscle tissue, producing enzymes and hormones, and supporting immune function. It is also the most satiating macronutrient — high-protein diets are consistently shown to reduce hunger and support fat loss while preserving muscle mass.

Recommended Daily Protein Intake

Goal / Activity LevelProtein per kg BWProtein per lb BW
Sedentary adult (minimum)0.8 g/kg0.36 g/lb
General fitness / active1.2–1.6 g/kg0.55–0.73 g/lb
Endurance athletes1.4–1.7 g/kg0.64–0.77 g/lb
Strength / muscle building1.6–2.2 g/kg0.73–1.0 g/lb
Weight loss (muscle preservation)1.8–2.7 g/kg0.82–1.23 g/lb

Best Protein Sources

  • Animal sources: Chicken breast (31g/100g), tuna (30g/100g), eggs (13g/100g), Greek yogurt (10g/100g)
  • Plant sources: Tofu (17g/100g), lentils (9g/100g), chickpeas (9g/100g), edamame (11g/100g)
  • Supplements: Whey protein (~25g per scoop), casein, pea protein

Distributing Protein Across Meals

Research shows that muscle protein synthesis is optimized by distributing protein evenly across 3–4 meals of 25–40g each, rather than eating most protein in one meal. The body can only utilize ~40g of protein at once for muscle building.
