Protein Requirement
Sedentary adults are advised 0.8–1 g per kg; people doing resistance training aim for 1.6–2.2 g. Since absorption per meal is limited, the per-meal share is shown too.

Frequently asked questions
Q. How is Protein Requirement calculated?
Protein = Weight (kg) × Dose (mg/kg) — Sedentary adults are advised 0.8–1 g per kg; people doing resistance training aim for 1.6–2.2 g. Since absorption per meal is limited, the per-meal share is shown too.
Q. Can you walk through an example?
With Weight (kg) 65, Dose (mg/kg) 1.6, the answer is Protein 104g.
Q. What do I need to enter?
Enter Weight (kg), Dose (mg/kg). The result recalculates as you type, and an empty box counts as zero.
Q. How much does the answer move if I change a number?
Changing only Weight (kg) moves the answer to Weight (kg) 32.5 → Protein (g) 52 and Weight (kg) 130 → Protein (g) 208. The table below lays out five steps.
Q. How are the numbers rounded?
Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.
Q. Anything to watch out for?
Kidney disease can require restricting protein — check with your clinician before raising intake.
