its said 1 gram of protein per pound of bodyweight is the minn u should intake and 2gm of protein per pound of body weight is optimal atleast for a bodybuilder ..some believe more .. broken down between 8 meals ..thats why people take protein shakes it can become a hassle and there4 people that depend on food alone .. are not gettin enough protein alot of the time ..not sayin it cant be done but its a pain in the ass
