1. What is Protein Needs Calculation?

The protein needs calculation estimates the daily protein requirement based on body weight and activity level or health status. It helps ensure adequate protein intake for muscle maintenance, growth, and recovery.

2. How Does the Calculator Work?

The calculator uses the protein needs formula:

\[ \text{Protein Needed (g)} = \text{Weight (kg)} \times \text{Factor (g/kg)} \]

Where:

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

Explanation: The equation accounts for different protein needs based on activity level, health status, and goals.

3. Importance of Protein Calculation

Details: Adequate protein intake is essential for muscle synthesis, immune function, and overall health. Calculating needs helps prevent both deficiency and excessive intake.

4. Using the Calculator

Tips: Enter weight in kg and select appropriate protein factor (typically 0.8g/kg for sedentary, 1.2-1.6g/kg for active, up to 2.0g/kg for athletes).

5. Frequently Asked Questions (FAQ)

Q1: What are typical protein factors?
A: Sedentary: 0.8g/kg, Active: 1.2-1.6g/kg, Athletes: 1.4-2.0g/kg, Elderly: 1.0-1.2g/kg, Injury recovery: 1.5-2.0g/kg.

Q2: How do I convert pounds to kg?
A: Divide weight in pounds by 2.205 to get kg (e.g., 150 lb ÷ 2.205 = 68 kg).

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

Q4: When should protein intake be higher?
A: During muscle building, injury recovery, pregnancy, or for elderly to prevent sarcopenia.

Q5: Should protein be evenly distributed?
A: Yes, spreading intake across meals (20-40g per meal) optimizes muscle protein synthesis.
