Protein requirement always differ according to your body size and activity levels. Some calculations are very simple, and many nutritionists calculate your protein requirements by dividing your total weight by two and the result indicates in grams the amount of protein you require each day.
For example, a person weighing 160 pounds requires approximately 80 grams of protein daily. Lean meats such as chicken and fish are great sources of protein. A 6oz chicken breast contains approximately 30 grams of protein and 6oz of white fish contains approximately 35 grams of protein.
