The need for protein is huge. The average person needs .5 grams to 1.0 grams of protein per day per pound of body weight. If you weight 150 pounds you need 75 grams to 150 grams per day of protein to be optimally healthy. An egg has about 7 grams of protein. You would have to eat 20 eggs per day to meet your daily needs. Meat which is cooked is difficult to measure how much protein you get. But still you would have to eat a lot. The only way to get the 75 to 150 grams of protein a day is if you supplement.
The only way to supplement with protein is to make sure that what you eat is a high quality protein. The best quality protein available is Whey Protein in powder form.
