Estimate daily protein in grams from body weight and activity level.

—

This result is a daily protein target in grams, to be split across meals during the day.

Formula

Daily protein in grams equals body weight in kilograms multiplied by a factor from 0.8 for sedentary up to 2.0 for heavy training.

How it works

Pick the factor that matches training, multiply by body weight, and the result is a daily gram target. Split it across meals rather than eating it all at once.

Worked example

For example, a weight of 70 kg at the Regular training factor of 1.6 g per kg gives 70 × 1.6 = 112 g of protein per day.
