1. What is Protein Requirement Calculation?

Protein requirement calculation estimates the daily amount of protein needed based on body weight and activity level or health status. It's essential for maintaining muscle mass, supporting recovery, and overall health.

2. How Does the Calculator Work?

The calculator uses the protein requirement formula:

Where:

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

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

3. Importance of Protein Calculation

Details: Proper protein intake supports muscle maintenance, immune function, and recovery. Requirements vary by age, activity level, and health conditions.

4. Using the Calculator

Tips: Enter weight in kilograms and select appropriate protein factor (0.8 g/kg for sedentary adults, 1.2-2.0 g/kg for athletes).

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: How do I convert pounds to kilograms?
A: Divide weight in pounds by 2.205 to get kilograms (e.g., 150 lbs ÷ 2.205 = 68 kg).

Q3: Can protein intake be too high?
A: While generally safe for healthy individuals, very high intake (>2.5 g/kg) long-term may stress kidneys in susceptible individuals.

Q4: When should protein intake be higher?
A: During recovery from illness/surgery, muscle building phases, or for elderly to prevent sarcopenia.

Q5: Are plant proteins calculated differently?
A: The calculation is the same, but plant proteins may need to be increased by 10-20% due to lower digestibility.
