You need protein for your muscles, bones, and the rest of your body. Exactly how much you need changes with age: Babies need about 10 grams a day. School-age kids need 19-34 grams a day. Teenage boys need up to 52 grams a day. Teenage girls need 46 grams a day. Adult men need about 56 grams a day.
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.
