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.
The amount of protein an active man needs each day is based on his activity level and body weight. The Institute of Medicine recommends that all men, regardless of activity level, consume at least 56 grams of protein every day.
