In the United States, the recommended daily allowance of protein is 46 grams per day for women over 19 years of age, and 56 grams per day for men over 19 years of age.
According to American Dietetic Association (ADA) recommendations, most active adults only need 0.8 grams of protein per kilogram of body weight per day. (A kilogram is 2.2 pounds.) So a person who weighs 125 pounds needs 45 to 57 g of protein in a day; for someone who weighs 175 pounds, itâs 65 to 80 g. Serious athletes need a bit more, but weâll get to that in a minute.
