How to Use the Recommended Protein Intake Calculator

Using the calculator is easy. Follow these simple steps:

Enter Your Body Weight: Input your weight in kilograms. Make sure to enter a positive number for accurate results.
Select Your Activity Level:
- Sedentary (0.8 g/kg): Minimal exercise, mostly sitting or low-intensity daily activities.
- Lightly Active (1.2 g/kg): Light exercise 1–3 times per week.
- Moderately Active (1.5 g/kg): Moderate exercise 3–5 times per week.
- Very Active (1.8 g/kg): Intense daily exercise or manual labor.

Example Calculation

Let’s see an example:

Body Weight: 70 kg
Activity Level: Moderately Active (1.5 g/kg)

Calculation:
Recommended Protein = Weight × Activity Level
= 70 × 1.5
= 105 g/day

This means a person weighing 70 kg with a moderate activity level should consume around 105 grams of protein per day to meet their nutritional needs.

Another example:

Body Weight: 85 kg
Activity Level: Athlete / Heavy Training (2.0 g/kg)

Calculation:
Recommended Protein = 85 × 2.0 = 170 g/day

This high-protein intake supports muscle recovery and performance for highly active individuals.
