What builds muscle?
Protein builds muscle. Without an adequate supply of protein, your body will not support any kind of muscle growth. If you supply your body with the optimum amount of protein, you ensure optimal growth, it's as simple as that.
After all, you want to build muscle and to do that, you need a steady supply of high quality protein. You must include an optimal amount of protein in your weight lifting diet in order to build and sustain muscle growth.
So how much protein should you include in your weight lifting diet for maximum performance and muscle gain? Each of us have very different body types and the amount of protein will differ from individual to individual.
Protein intake will also depend on the amount of activity involved and how frequently you do it.
Your weight lifting diet should be comprised of 20% to 30% protein. That roughly translates to .8 to 1.3 grams of protein per pound of body weight. If you weight 145 pounds, your daily protein intake should be anywhere from 102 grams to 189 grams of protein per day.
You will have to do a bit of experimenting at the beginning to find out your optimal protein intake.

Of course, that's a rough estimate. But the two trainer's I've been under have given me this guidline to not gorge on just protein. And it's ok to disagree.
