Why Protein Matters

Learn how protein supports your health, fitness, and body composition goals.

Essential Building Block
Protein is crucial for building and repairing tissues, making enzymes and hormones, and supporting immune function. Your body cannot store protein.
Muscle Maintenance
Adequate protein intake helps preserve lean muscle mass, especially during weight loss or as you age. Critical for metabolic rate.
Weight Management
Protein is the most satiating macronutrient, helping you feel full longer and potentially reducing overall calorie intake.
Complete Proteins
Contain all nine essential amino acids. Found in animal products (meat, fish, eggs, dairy) and some plants (quinoa, soy, hemp seeds).
Protein Timing
Spread protein intake across 3-4 meals for optimal muscle protein synthesis. Aim for 20-40g per meal depending on total needs.
Individual Needs
Protein requirements depend on age, activity level, health status, and goals. Active individuals and older adults typically need more.

  • Maintain muscle mass
  • Good for sedentary people

Weight Loss

1.2-1.6g/kg

  • Preserve muscle during deficit
  • Increase satiety
  • Boost metabolic rate
  • Support fat loss

Muscle Building

1.6-2.2g/kg

  • Optimize protein synthesis
  • Support recovery
  • Maximize muscle growth
  • Enhanced with resistance training
