Summary
Broad daily protein gram range by body weight and activity goal.
Calculation details
Ranges are general references, not individualized nutrition prescriptions. Needs vary with total diet, training, age, pregnancy, and health status.
Formula
Range = body weight × multiplier: general 0.8–1.0, active 1.2–1.6, endurance 1.2–1.8, strength 1.6–2.2 g/kg/day.
Worked example
Protein intake worked example
A 70 kg active adult receives a broad 84–112 g/day reference range.
How it works
Enter body weight and a broad activity goal. Treat the gram range as dietary planning reference, not a prescription — especially with kidney or clinical conditions.
Frequently asked questions
Is this a medical diagnosis?
No. It is an educational estimate and cannot diagnose a condition or replace individualized professional advice.
Why can my actual result differ?
Training load, age, pregnancy, and medical conditions change protein needs.
When is this calculator most useful?
Use it to sketch a gram range by activity goal before personalizing with a dietitian if needed.
How are results rounded?
The calculation retains full precision; centralized display formatting rounds only the visible result.
