There's an awful lot of discussion about protein these days, and many sources cite specific ranges per kilogram of body weight.
Here's a handy tool that will quickly calculate what those different ranges mean for you. Just enter your weight (in pounds or kilograms) and click the "calculate" button to see your options.
I suggest that you hold these targets loosely! The difference between 100 and 105 grams of protein per day is not likely to be game-changing. (But the difference between 60 and 100 may be!)
