1. What is Protein Per Body Weight Calculation?

The protein per body weight calculation estimates daily protein requirements based on an individual's body weight and a protein factor that varies by activity level and health status.

2. How Does the Calculator Work?

The calculator uses the protein calculation formula:

Where:

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

Explanation: The equation multiplies body weight by a standard protein factor to determine daily protein needs.

3. Importance of Protein Calculation

Details: Accurate protein calculation is crucial for maintaining muscle mass, supporting recovery from illness or injury, and meeting nutritional needs for different activity levels.

4. Using the Calculator

Tips: Enter weight in kilograms and select appropriate protein factor. Common factors: 0.8 g/kg (sedentary), 1.2-1.6 g/kg (athletes), 1.2-2.0 g/kg (illness/recovery).

5. Frequently Asked Questions (FAQ)

Q1: What are typical protein factors?
A: 0.8 g/kg for healthy adults, 1.2-1.6 g/kg for athletes, 1.2-2.0 g/kg for illness/recovery, and up to 2.5 g/kg for severe catabolic states.

Q2: How often should protein needs be recalculated?
A: Recalculate whenever body weight changes significantly or activity level/health status changes.

Q3: Should protein be evenly distributed?
A: Yes, protein should be evenly distributed across meals (20-40g per meal) for optimal muscle protein synthesis.

Q4: Are there risks to high protein intake?
A: In healthy individuals, up to 2g/kg is generally safe. Those with kidney disease should consult a doctor before increasing protein.

Q5: How does age affect protein needs?
A: Older adults may need 1.0-1.2 g/kg to combat age-related muscle loss (sarcopenia).
