What is Protein Calculator?
A protein calculator determines optimal essential amino acid intake to maximize muscle protein synthesis (MPS), prevent sarcopenia, and accelerate post-workout recovery.
How to Use This Calculator
- Enter your body weight in pounds or kilograms.
- Select your training objective (maintenance, endurance, muscle hypertrophy, or fat loss cutting).
- Distribute the calculated daily protein target across 3 to 5 meals.
The Mathematical Formula & Variables
Protein(g) = Weight(lbs) * Target Factor (0.8 to 1.0 for athletes)
Variables Definition
| Symbol / Variable | Name | Description |
|---|---|---|
0.8 g/kg |
RDA Minimum | Minimum baseline to prevent clinical deficiency, not optimal for active athletes. |
Step-by-Step Worked Example
Scenario: 165 lb individual training for muscle hypertrophy.
- Target multiplier = 0.85 to 1.0 g per lb.
- 165 * 0.85 = 140 grams; 165 * 1.0 = 165 grams.
- Divided across 4 meals = ~38g protein per meal.
Result: Target: 140 to 165 grams/day
Frequently Asked Questions
Can eating too much protein harm healthy kidneys?
Extensive clinical reviews confirm that high-protein diets (up to 1.5 g/lb or 3.3 g/kg) do not impair renal function or bone health in individuals with healthy kidneys.
