The more protein you eat, the more muscle you will build, right? Wrong.
The body only needs so much protein every day; when you surpass its requirements, it simply processes the extra calories the same way it would excess carbohydrate or fat calories. The protein is broken down, and some of it is excreted while some is stored as body fat or used as energy. The requirements for protein are 1.2 to 1.5 grams per kilogram of bodyweight; this amount will ensure that your body is getting enough of the building blocks it requires to create new muscle.
Rather than ingesting too much protein, a better option would be to supplement your diet with good sources of carbohydrates, as they are the body’s preferred source of energy to create the muscle tissue from the protein you took in.
Whatever your goal, many organizations and individuals (particularly within the bodybuilding community), insist on athletes eating an extraordinarily high amount of protein sometimes more than triple the levels typically recommended by international government health boards.
