1. What is Protein Requirement Calculation?

The protein requirement calculation estimates daily protein needs based on body weight and activity level. It helps individuals meet their nutritional needs for maintenance, growth, or recovery.

2. How Does the Calculator Work?

The calculator uses the protein equation:

Where:

• \( Weight \) — Body weight in kilograms
• \( Factor \) — Protein factor in grams per kilogram (g/kg)

Explanation: The equation multiplies body weight by a standard protein factor that varies based on activity level and health status.

3. Importance of Protein Calculation

Details: Adequate protein intake is essential for muscle maintenance, immune function, and overall health. Calculating protein needs helps prevent both deficiency and excess intake.

4. Using the Calculator

Tips: Enter weight in kilograms and select an appropriate protein factor (default is 0.8 g/kg for sedentary adults). Athletes may need 1.2-2.0 g/kg depending on training intensity.

5. Frequently Asked Questions (FAQ)

Q1: What are typical protein factors?
A: Sedentary adults: 0.8 g/kg; Endurance athletes: 1.2-1.4 g/kg; Strength athletes: 1.6-2.0 g/kg; Elderly: 1.0-1.2 g/kg.

Q2: Is more protein always better?
A: No, excessive protein (≥2.5 g/kg long-term) may strain kidneys in susceptible individuals and provide no additional benefits.

Q3: Should protein be adjusted for body fat?
A: For overweight individuals, some experts recommend calculating based on ideal or adjusted body weight rather than actual weight.

Q4: How does protein need change with age?
A: Older adults often need more protein (1.0-1.2 g/kg) to combat age-related muscle loss (sarcopenia).

Q5: When should protein intake be higher?
A: During recovery from illness/surgery, pregnancy/lactation, and when attempting muscle growth.
