Calculators for Protein Requirements
Protein Needs Calculators for Adults

It's important that we eat enough protein each day to cover our body's needs. Here are two calculators to help you figure out your protein requirements. As I described in How Much Protein Do You Need?, the standard minimum amount of daily protein recommended is .37 gram per pound of body weight (or .8 grams per kilogram of body weight). However this is a minimum - it has been shown that up to 1.2 grams of protein per kg of body weight could be even better for health, and up to 1.8 grams for athletes. This first calculator will calculate that range for you.

Protein Needs Calculator
The second way to calculate protein needs uses lean body mass and activity level rather than total body weight. The thinking is that fat tissue does not need as much protein to support it as lean tissue. The books The Zone by Barry Sears, and Protein Power by Michael and May Dan Eades use this method, which is described here. The steps are:

1) Figure out your body fat percentage (calculator based on the tape measure method here) (other methods here)
2) Plug that number, your total body weight, and your activity level into the calculator below. (Descriptions of the different activity levels on this page)
