Mathematical Formula & Variables
Equation Model
Protein (g/day) = Weight (kg) * Recommended RatioDaily protein targets are calculated based on overall body mass and scaled by coefficients associated with exercise intensity and fitness goals.
Variable Definitions
| Symbol | Description |
|---|---|
| Weight (kg) | Total weight in kilograms |
| Recommended Ratio | From 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.
