1. What is Protein Intake Calculation?

Protein intake calculation estimates the daily protein requirement based on body weight and activity level. It helps ensure adequate protein consumption for muscle maintenance, growth, and overall health.

2. How Does the Calculator Work?

The calculator uses the protein intake formula:

Where:

• \( Weight \) — Body weight in kilograms
• \( Factor \) — Protein requirement factor in g/kg/day

Explanation: The equation multiplies body weight by a protein factor that varies based on activity level, goals (maintenance vs. muscle gain), and health status.

3. Importance of Protein Calculation

Details: Proper protein intake supports muscle protein synthesis, immune function, and tissue repair. Both inadequate and excessive protein can have health consequences.

4. Using the Calculator

Tips: Enter weight in kilograms and select an appropriate protein factor (typically 0.8-2.2 g/kg/day depending on activity level and goals).

5. Frequently Asked Questions (FAQ)

Q1: What protein factor should I use?
A: Sedentary adults: 0.8-1.0 g/kg/day; Active individuals: 1.2-1.6 g/kg/day; Athletes/bodybuilders: 1.6-2.2 g/kg/day.

Q2: Is more protein always better?
A: No, excessive protein (≥2.5 g/kg/day long-term) may strain kidneys in susceptible individuals and displace other important nutrients.

Q3: Should protein be adjusted for age?
A: Older adults may benefit from higher protein intake (1.0-1.2 g/kg/day) to combat sarcopenia.

Q4: What about plant-based proteins?
A: Plant proteins can meet requirements but may need combining different sources to get all essential amino acids.

Q5: When should protein intake be higher?
A: During muscle-building phases, injury recovery, or certain medical conditions like severe burns.
