The USDA's Recommended Dietary Allowance (RDA) for protein is .8 grams per kilogram (or .36 grams per pound) of body weight. But that's not enough for athletes, according to the ISSN, which says endurance athletes like runners need 1.0 to 1.6 grams per kilogram a day (or .45 to .72 grams per pound).
The US Department of Agriculture recommends that all men and women over the age of 19 should get at least 0.8 grams of protein per kilogram of body weight per day (or 0.37 grams per pound). That means a woman who is 130 pounds should get at least 48 grams of protein, which could look like 7 ounces of salmon or 7 eggs.
