# How much protein do exercising adults need?

The ISSN position stand gives 1.4–2.0 grams of protein per kilogram of body weight per day as a range sufficient for most healthy exercising individuals. It is a general range, not an exact requirement for every adult or a prescription for a medical condition.

## A range is more honest than one perfect number

The relevant question is the population: guidance for healthy exercising adults should not silently become advice for children, pregnancy, kidney disease, or clinical recovery. Nor does it establish a target for every person who happens to own a fitness tracker.

A meta-analysis of resistance-training studies found average gains in fat-free mass did not increase further beyond about 1.6 g/kg/day. That is a group-level finding with uncertainty, not a sharp ceiling at which protein becomes useless or harmful.

## Convert weight into a daily range

Use body weight in kilograms, then multiply by each end of the range. If the weight is in pounds, convert it first: 1 lb equals 0.45359237 kg. Do not multiply pounds by a grams-per-kilogram recommendation.

For an illustrative 70-kg adult, the calculation gives 98–140 g/day. Those are grams of the nutrient, not grams of a food such as chicken, beans, or yogurt. The calculator shows the same arithmetic, rounded to whole grams.

Illustrations of the public range, not individualized prescriptions.
| Body weight | At 1.4 g/kg | At 2.0 g/kg |
| --- | --- | --- |
| 60 kg | 84 g/day | 120 g/day |
| 70 kg | 98 g/day | 140 g/day |
| 80 kg | 112 g/day | 160 g/day |

## Turn the number back into food

A useful next step is to inspect the protein in meals you already eat. Read the amount per serving and scale it to your actual portion; a package weight is not the amount of protein it contains.

For planning, a hypothetical 120 g across four eating occasions averages 30 g each. This is a way to visualize the arithmetic, not a required meal frequency or timing protocol. You do not need to make every meal identical.

## When not to use this tool

This illustration is for healthy exercising adults. It does not choose between actual, ideal, or adjusted body weight in clinical situations, prescribe supplements, or account for a specialized sport or diet.

For kidney disease, pregnancy, breastfeeding, prescribed diets, eating-disorder recovery, or other medical concerns, ask a qualified professional. More protein is not automatically better, and reaching a protein number does not establish that the rest of a diet is adequate.

## Protein range calculator

Convert the ISSN range for healthy exercising adults into grams per day. This is not an individualized protein prescription.

Inputs and results stay in this page. No account, saving, or calculator analytics. These tools are separate from POWR’s app targets.

Supported inputs are a tool boundary, not proof of suitability. Weight: 30–300 kg (about 66–661 lb). For values outside the supported range or an excluded situation, seek individual guidance.

## Sources and limits

These sources support the claims beside which they are linked. Practical checklists and invented examples are POWR’s educational interpretation, not findings from a trial of the app.
