1. What is Protein Calculation?

Protein calculation based on body weight is a method to estimate daily protein requirements for individuals. The calculation multiplies a person's weight by a factor that varies depending on activity level, health status, and goals.

2. How Does the Calculator Work?

The calculator uses the protein calculation formula:

Where:

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

Explanation: The equation provides a simple way to estimate protein needs based on body weight and activity level factors.

3. Importance of Protein Calculation

Details: Proper protein intake is essential for muscle maintenance, recovery from exercise, immune function, and overall health. Accurate calculation helps meet individual nutritional needs.

4. Using the Calculator

Tips: Enter body weight in kilograms and select an appropriate protein factor (typically 0.8 g/kg for sedentary adults, up to 2.2 g/kg for athletes). All values must be positive numbers.

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: 1.6-2.2 g/kg; Elderly: 1.0-1.2 g/kg.

Q2: Should I use actual or ideal body weight?
A: For overweight individuals, some recommend using adjusted body weight. Consult a dietitian for personalized advice.

Q3: Is more protein always better?
A: No, excessive protein can strain kidneys in susceptible individuals and may displace other important nutrients.

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

Q5: What about plant-based proteins?
A: Plant proteins can meet requirements but may need combining different sources to get all essential amino acids.
