However, there are vastly different opinions on how much protein we actually need. Most official nutrition organizations recommend a fairly modest protein intake. The DRI (Dietary Reference Intake) is 0.8 grams of protein per kilogram of body weight, or 0.36 grams per pound. This amounts to: 1  56 grams per day for the average sedentary man.  46 grams per day for the average sedentary woman.
Because men take in more calories per day, they need more protein than women. The average man in the Unites States takes in about 100 grams of protein per day, while the average woman takes in approximately 70 grams, according to the National Health and Nutrition Examination Survey. The amount of protein you need daily depends on your total caloric intake, gender and activity level.
