It depends when are you trying to gain muscle or just maintain. When I am trying to gain muscle (bulking cycle). I eat 3-4 grams per pound of body weight.For just regular maintenence I eat 1-1.5 grams per pound of body weight. I break it up into six small meals a day. Try to combine a good protein shake and chicken and turkey to give you some variety. You should also take Vitamin B6 is needed for protein metabolism, red blood cell metabolism, and proper functioning of the nervous and immune systems.
