1. What is Daily Protein Intake?

Daily protein intake refers to the amount of protein (in grams) a person should consume each day based on their body weight and activity level. Protein is essential for muscle repair, immune function, and overall health.

2. How Does the Calculator Work?

The calculator uses the protein intake formula:

Where:

• \( Weight \) — Body weight in kilograms
• \( Protein Factor \) — Recommended grams of protein per kg of body weight

Explanation: The protein factor varies based on activity level and goals (e.g., 0.8g/kg for sedentary, 1.2-1.6g/kg for active, up to 2.2g/kg for athletes).

3. Importance of Protein Calculation

Details: Proper protein intake supports muscle maintenance, recovery after exercise, and overall metabolic health. Both inadequate and excessive protein can have health consequences.

4. Using the Calculator

Tips: Enter your weight in kg and select an appropriate protein factor based on your activity level. Common factors range from 0.8 (sedentary) to 2.2 (strength athletes).

5. Frequently Asked Questions (FAQ)

Q1: How do I convert pounds to kilograms?
A: Divide your weight in pounds by 2.205 to get kilograms (e.g., 150 lbs ÷ 2.205 = 68 kg).

Q2: What protein factor should I use?
A: Sedentary: 0.8g/kg, Active: 1.2-1.6g/kg, Endurance athletes: 1.4-1.8g/kg, Strength athletes: 1.6-2.2g/kg.

Q3: Is more protein always better?
A: No, excessive protein (especially from animal sources) may strain kidneys in susceptible individuals and displace other important nutrients.

Q4: Should protein intake change with age?
A: Older adults may benefit from slightly higher protein intake (1.0-1.2g/kg) to combat sarcopenia (muscle loss with aging).

Q5: What about protein timing?
A: While total daily intake is most important, spreading protein across meals (20-40g per meal) may optimize muscle protein synthesis.
