Protein is an essential nutrient, and is vital to your health. It is used to build muscles, skin, hair and nails. However, many people put their health at risk by eating too much protein.
The typical American diet already provides plenty of protein and there is no point in adding any more, unlike fat cells, there is no place in the body to store protein so the excess is eliminated or is seen as fat rather than muscle.

So what you need to do is to consume just enough protein to allow your muscles to be healthy, perform work and grow. But how much is just enough?

You only use protein for about 15% of your energy use, the majority of energy comes from fats and carbohydrates. Exercising doesn’t necessarily mean that you require more protein but more carbohydrates to stop your body breaking down protein and using that for energy.

Try to make sure that 70% of your protein comes from sources such as meat, fish, eggs or poultry. The complete protein provided by these foods combines with incomplete protein consumed from other food sources. So your body makes the best of all the protein that you consume.
If you are consuming too much protein, you are probably consuming too many calories over your maintenance levels and this will show as an increase in your body fat levels. And with the advent of the latest fad high protein diets, not enough carbohydrates are being consumed so the protein is converted to glucose and not converted into muscle growth.

What is needed for muscle growth is not more protein but high intensity strength training with the required amount of time for rest and recovery between sessions. Because that major bodybuilding star you saw in the latest magazine requires 300 grams of protein a day doesn't mean that you have to. What he won't tell you is that taking Steroids is behind his muscle gains and not his diet.

High intensity strength training and not food stimulates muscle growth.
Consuming excessive amounts of protein is not only bad for your liver and kidneys but also promotes vitamin and mineral deficiencies. It is also linked to osteoporosis and some forms of cancer.
One way to overcome the need to eat large quantities of protein is to increase the consumption of protein in stages until a maximum efficiency point is reached and then to drastically reduce it again. This obliges the body to over-compensate by increasing the efficiency for the absorption of protein into the body.
