1. What is Protein Requirement Calculation?

The protein requirement calculation estimates the daily protein needs based on body weight and age group. It provides personalized recommendations to maintain muscle mass and overall health.

2. How Does the Calculator Work?

The calculator uses the protein requirement equation:

Where:

• \( Weight \) — Body weight in kilograms
• \( 0.8 \) — Protein factor for adults (18-64 years)
• \( 1.2 \) — Protein factor for elderly (65+ years)

Explanation: The equation accounts for increased protein needs in older adults to prevent sarcopenia (muscle loss).

3. Importance of Protein Calculation

Details: Adequate protein intake is crucial for muscle maintenance, immune function, and overall health. Requirements increase with age to combat age-related muscle loss.

4. Using the Calculator

Tips: Enter your weight in kilograms and select your age group. The calculator will provide your estimated daily protein requirement in grams.

5. Frequently Asked Questions (FAQ)

Q1: Why do elderly need more protein?
A: Older adults need more protein (1.2 g/kg) to counteract age-related muscle loss (sarcopenia) and maintain strength.

Q2: What if I'm very active or athletic?
A: Active individuals may need 1.2-2.0 g/kg depending on activity level. Consult a sports nutritionist for personalized advice.

Q3: Can I consume too much protein?
A: While generally safe for healthy individuals, very high intake (>2g/kg long-term) may stress kidneys in susceptible people.

Q4: Should protein be spread throughout the day?
A: Yes, consuming 20-40g of protein per meal (3-4 meals) optimizes muscle protein synthesis better than one large serving.

Q5: Are plant proteins as effective as animal proteins?
A: Plant proteins can meet requirements but may need combining different sources to get all essential amino acids.
