Interestingly, you may think of muscles as all protein. Actually 15 to 20 percent is protein, 70 to 75 percent is water, and 5 to 7 percent is fat, glycogen, and minerals. For anyone, protein should supply 10 to 35 percent of overall calorie intake. How much protein do you need to gain volume? Adults building muscle mass may need 0.7 to 0.8 gram of protein per pound. Teen athletes need enough for growth and muscle building : 0.7 to 0.9 gram of protein per pounds. But if you don’t consume enough carbohydrates for your high-energy demands, your body uses protein for energy instead. Caution about excess protein: Extra protein is not stored in your body for future use as protein. Instead, it’s either used as energy or stored as body fat. A high protein diet also may be high in fat.
