Quick Targets

Enter your details and choose a protein target to see your calculated daily protein and meal distribution.

How the Protein Intake Calculator Works

This calculator multiplies body weight in kilograms by the grams-per-kilogram protein target you choose. For example, an 80 kg person selecting 1.6 g/kg produces a calculated total of 128 grams of protein per day. FitnessScopes then divides that calculated total evenly across the number of meals selected.

Why Protein Targets Vary

Protein intake is often expressed relative to body weight, but there is no single grams-per-kilogram value that is appropriate for every person or situation. Factors such as age, overall diet, training, energy intake, body composition goals and health can affect the context in which protein recommendations are considered. That is why this tool asks you to choose the target rather than automatically assigning one.

Protein calculator disclaimer: This calculator performs arithmetic from the grams-per-kilogram target you choose. It does not determine an individual medical or nutrition requirement.
