About Protein Requirements
Daily protein needs vary based on several factors including age, gender, activity level, and your fitness goals.
- Age: Younger individuals may need slightly more protein for growth, while older adults might need adjustments due to metabolic changes.
- Gender: Protein requirements can differ slightly, but this calculator uses general guidelines for all genders.
- Activity Level & Goal: More active individuals or those aiming to gain muscle require higher protein intake.

Understanding Protein Requirements
Protein is essential for building and repairing tissues, supporting immune function, and maintaining muscle mass. Your daily protein needs depend on weight, age, gender, activity level, and fitness goals.
Factors Affecting Protein Needs
- Weight: Heavier individuals generally require more protein.
- Age: Protein needs can increase during growth or slightly decrease in older adults due to metabolic changes.
- Gender: Differences are generally minor, but hormonal and physiological factors can play a role.
- Activity Level: More active individuals need higher protein intake for recovery and performance.
- Fitness Goal: Muscle gain or fat loss goals require more protein than maintenance.
- Body Composition: Using lean body mass instead of total weight can provide a more precise protein estimate.
Recommended Daily Intake
General guidelines suggest 0.8–1.2 grams per kilogram of body weight for sedentary adults, 1.4–1.8 g/kg for moderately active individuals, and up to 2.0 g/kg for athletes or those seeking muscle gain.
