Protein Intake Calculator

How to calculate protein intake?

Protein intake is determined by your total body mass and physical activity intensity. This relationship is driven by muscle protein synthesis, where the body uses dietary amino acids to repair tissues and build new muscle fibers after physical exertion.

Protein (g) = Weight (kg) × Activity Factor

Using the Protein Calculator: An Example

Consider a sample user: A 180 lb individual aiming for muscle growth. To find their ideal intake, we apply the standard conversion and factor multipliers.

Step-by-step calculation:

1. Convert 180 lbs to 81.6 kg
2. Multiply 81.6 kg by a 1.6 factor
3. Result is ~130g of protein per day

Does the source of protein matter?
Complete proteins containing all essential amino acids are best for recovery.

When is the best time to consume protein?
Spreading intake evenly across 3-5 meals is more effective than one large dose.
