Protein Intake Calculator
Translate body weight into a daily protein reference range, with separate baseline and training contexts. The result is a rough planning reference, not a target that every person should pursue.

The math behind it
Formula and assumptions
Daily protein estimate = body weight in kilograms × reference grams per kilogram: 0.8 g/kg for the adult baseline reference, or 1.2–2.0 g/kg for a training reference.
Two references, different contexts
The baseline option uses 0.8 grams per kilogram of body weight per day, a widely used adult recommended dietary allowance reference. It is a population-level reference for generally healthy adults, not a precise individualized requirement and not necessarily appropriate during every life stage or health condition. The training option displays a broader 1.2 to 2.0 grams per kilogram range often discussed for people undertaking regular exercise. Choosing it does not mean that everyone is an athlete or needs more protein; training type, total food intake, goals and recovery all matter.
The calculation multiplies the weight you enter by the selected reference values. It does not account for body composition, the quality or distribution of foods, energy needs, age, pregnancy, or clinical history. A range is deliberately more honest than a single exact-looking target. Protein comes from varied foods, including beans, lentils, dairy, eggs, fish, meat, nuts and seeds. Dietary pattern, affordability, allergies and cultural preferences can shape practical choices just as much as arithmetic.
When a simple range is not enough
People with kidney disease or who have been told to limit protein should not use the training range as advice; follow the guidance of their treating team. Other medical conditions, pregnancy, older age, recovery needs and prescribed diets can also change what is appropriate. If you have a relevant condition, consult a clinician or registered dietitian before making a substantial change. More protein is not automatically better, and this tool cannot determine whether your current diet is adequate or whether a supplement is useful.
The displayed amount is a daily total estimate, not a required dose to consume all at once. Ordinary meals can contribute protein across the day, and foods provide nutrients beyond protein as well. Avoid interpreting the output as a weight-loss method, a muscle-gain promise or a reason to exclude other food groups. Use it to understand the math behind a reference range, then consider whether it fits your circumstances. The tool stores no input and does not offer medical nutrition therapy.

Common questions
Before you use this number
Is 0.8 g/kg a personal prescription?
No. It is a general adult baseline reference; individual needs can differ with age, health, life stage and activity.
Who is the training range for?
It is an illustrative 1.2–2.0 g/kg reference for training contexts, not a claim that every user is an athlete or needs that amount.
What if I have kidney disease?
Do not use a generic higher-protein range as guidance. Follow individualized advice from your clinician or dietitian.
