About Protein Requirements

Protein is an essential macronutrient that plays a crucial role in building and repairing tissues, supporting immune function, and producing enzymes and hormones.

General Guidelines

Protein requirements vary based on individual factors such as weight, activity level, and specific goals:

  • Sedentary adults: 0.8 g/kg of body weight
  • Recreational exercisers: 1.1-1.4 g/kg of body weight
  • Endurance athletes: 1.2-1.4 g/kg of body weight
  • Strength/power athletes: 1.4-2.0 g/kg of body weight
  • Athletes during caloric restriction: 1.8-2.2 g/kg of body weight
  • Growing athletes/bodybuilders: Up to 2.2-3.0 g/kg of body weight
Timing and Distribution

For optimal muscle protein synthesis, research suggests:

  • Consuming protein evenly throughout the day in 3-5 meals
  • Including 20-40g of protein per meal (depending on body size)
  • Consuming protein within 1-2 hours after training
  • Including some protein before sleep to support overnight recovery
Protein Quality

Not all protein sources are equal. Proteins are evaluated based on:

  • Digestibility: How efficiently the body can break down and absorb the protein
  • Amino acid profile: Complete proteins contain all essential amino acids
  • Leucine content: Leucine is particularly important for muscle protein synthesis

High-quality proteins include animal sources (meat, eggs, dairy) and some plant combinations (legumes with grains).

Special Considerations
  • Aging: Older adults may benefit from higher protein intake (1.0-1.2 g/kg)
  • Weight loss: Higher protein intake helps preserve lean muscle during caloric deficit
  • Injury recovery: Increased protein needs during healing and rehabilitation
  • Plant-based diets: May require 10-15% more total protein due to lower digestibility
Common Protein Sources

Protein content per 100g of common foods:

  • Chicken breast: 31g
  • Greek yogurt: 10g
  • Eggs: 13g
  • Salmon: 25g
  • Lean beef: 26g
  • Tofu: 8g
  • Lentils: 9g
  • Whey protein powder: 80-90g
