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.
How Much Protein Do You Need? Protein needs depend on age, size, and activity level. The standard method used by nutritionists to estimate the minimum daily protein requirement is to multiply your body weight in kilograms by 0.8, or weight in pounds by 0.37. This is the number of grams of protein that should be the daily minimum. According to this method, a person weighing 150 pounds should eat about 55 grams of protein per day, a 200-pound person should get 74 grams, and a 250-pound person should eat 92 grams. An easier way to judge protein needs: ounce equivalents.
