Recommended Daily Protein Targets

Minimum Baseline112g / day1.6 g/kg ratio
Optimal Recommendation126g / day1.8 g/kg ratio
High Athletic Intake154g / day2.2 g/kg ratio

Mathematical Formula & Variables

Equation ModelProtein (g/day) = Weight (kg) * Recommended Ratio

Daily protein targets are calculated based on overall body mass and scaled by coefficients associated with exercise intensity and fitness goals.

Weight (kg)Total weight in kilograms
Recommended RatioFrom 0.8 g/kg (sedentary) to 2.2 g/kg (intensive muscle hypertrophy)

How to Use the Protein Intake Calculator

  • Enter your weight and height in metric or imperial.
  • Specify your current activity level and primary fitness goal.
  • Click calculate to get a breakdown of minimum, optimal, and athletic protein quotas.

Practical Example Calculation

Scenario Context: Calculating optimal protein for an 80 kg (176 lbs) male weight lifter.

Step 1: Determine athletic ratio factor: 1.8 to 2.2 grams per kilogram.
Step 2: Multiply weight by minimum ratio: 80 * 1.8 = 144 grams.
Step 3: Multiply weight by high ratio: 80 * 2.2 = 176 grams.
The optimal daily protein range is 144g to 176g.
