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.
1 The RDA (recommended dietary allowance) for protein is 0.8 grams per kilogram of body weight of adults (or roughly 0.36 grams per lb of body weight). 2  Or I have also seen advised that women need at least 46 grams of protein per day, and men need at least 56 grams of protein per day (to avoid deficiency).he other part of the equation when it comes to why you eat protein, is about your goals and how many calories you are intaking. Many people use the higher protein intakes when they are looking to lean out and minimize muscle loss.
