Amount of protein required for a woman will totally depend on her diet and fitness level. Active women that are looking to build muscle and lose fat should consume 0.8 grams of protein per pound of body weight each day. For a 150lb. woman, that means 120 grams of protein per day. American Dietetic Association, Dietitians of Canada and the American College of Sports Medicine recommend that athletes consume 1.2 to 1.7 grams of protein per kilogram of body weight or .5 to .8 per pound.
