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.
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.
