How the Protein Intake Calculator Works

Daily Protein = Body Weight (kg) × Goal Factor (1.2-2.4 g/kg)

This calculator determines your ideal daily protein intake based on your body weight, fitness goal, and activity level. Protein is essential for muscle building, repair, and maintenance, especially during weight loss.

Tips

  • 1

    Distribute protein across 4-5 meals daily for better absorption

  • 2

    Consume 20-40g protein within 2 hours post-workout for optimal recovery

  • 3

    High-quality protein sources: chicken, fish, eggs, whey, dairy

  • 4

    Drink adequate water with high protein intake to support kidneys

Common Mistakes

  • Consuming all protein in one or two meals, reducing absorption

  • Relying only on supplements instead of real food

  • Neglecting protein on rest days despite its importance for recovery

  • Not adjusting amount after weight or goal changes
