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.
Calculate your daily protein needs. Typical people need about .4 grams of protein per pound of body weight each day. Active people require .6 grams per pound. And athletes or bodybuilders can require .9 grams or more per pound. Being the 160lb gym addict that I am, I aim for 140 grams of protein a day.
