Consume 0.31 to 0.36 grams of protein per pound of body weight per day. If you weigh 130 pounds, that comes to about 40 to 47 grams of protein per day, of which 30 grams should be consumed in a single meal to maximize muscle synthesis. If you weigh 200 to 220 pounds and have 35 percent body fat or higher, 60 to 70 grams of protein per day is sufficient, since fat cells require lower levels of protein than muscles. Since this minimum requirement can change from person to person, it is preferable to occasionally consult a dietitian, to make sure that a healthy, lean body mass is maintained.
