If you're training hard or looking to get larger, aim for around 1 gram per pound of body weight, or around 2.3 grams per kilogram. No, it doesn't have to be exact, but even if dietary protein is the only thing you measure in your diet, it could be what you need to finally see the serious results you've been wanting.

Remember, lifting weights stimulates muscle synthesis or growth, but it also increases muscle breakdown—so much so that when you exercise in a fasted state, you can break down more muscle than your body is building. Consuming protein foods immediately before or after working out can help you balance breakdown with growth.
