Protein: daily Protein Range
Estimate a general protein range from body weight and activity/goal assumptions without disease-specific advice.
Inputs this tool uses
- Weight
- Goal / activity
What you get
General protein range based on body weight and selected context.
How to use the Protein Calculator
- Enter weight, goal / activity.

How this calculation works
Macronutrient energy uses 4 kcal/g for protein, 4 kcal/g for carbohydrate, 9 kcal/g for fat and 7 kcal/g for alcohol when entered.
Example calculation
The sample values loaded into the calculator produce 56–84 g/day. This example exists to show how the output is structured; replace the sample values with your own inputs for your calculation.
Assumptions and limitations
- Energy and nutrient outputs are estimates or general reference values, not individualized treatment targets.
- Adult calorie-goal tools should not be used for children, pregnancy or medical nutrition therapy unless the page explicitly supports that life stage.
