How this calculator can help
A range is more honest than a single perfect number. The result can help you distribute protein across meals, while leaving room for food preferences and total dietary quality. Medical conditions can change what is appropriate.
How the estimate works
The baseline for healthy adults is 0.8 grams per kilogram of body weight per day. Higher activity selections use broader evidence-based ranges, shown transparently in the result. This is not designed for pregnancy, breastfeeding, kidney disease, or a prescribed diet.
Sources and methodology
We use transparent formulas and primary public-health or research sources. Calculators simplify real life, so their results should be interpreted as estimates.
