Does Excess Protein Turn to Fat?

Everyone knows that overeating leads to excess weight. This concept comes in many flavors these days, though. Some people think that carbohydrates are the culprit. Others think it's sugar. Some people think that eating lots of protein couldn't possibly make them gain weight. Hmmm . . .
Let’s get a complete picture of how the body metabolizes food.  All food is made up of three rudiments.  Carbohydrate, Fat and Protein.  Below is a simple explanation of the digestive process:
The food enters your mouth:
•    Saliva contains enzymes that starts converting carboyhrate in the food down to sugar.
•    This, along with any fat and water in the food, travel to the stomach, which churns them up.
•    Pepsin (an enzyme that digests protein) and hydrochloric acid further break down the food, turning it into a substance called chyme.
•    The mixture enters the duodenum, (the place where the gall bladder secretes its bile).
•    This bile dissolves the fat in water, thinning it out and making it easier to absorb.
•    Enzymes from the pancreas enter the duodenum and further break down the sugar, fat and protein.
Now everything is dissolved and is in fluid form, so it is absorbed through the lining of the small bowel. Fat, sugar and protein wave good-bye to each other and go their separate ways.
What happens to the sugar:
•    It also goes directly into the blood stream, and several different organs take the sugar they need as it passes by.
•    Some is stored in the liver as glycogen.
•    Whatever is left is converted to fat and stored in fat cells with the excess fat above.
What happens to the fat:
•    First, it goes into the blood stream and travels to the liver
•    The liver burns some of the fat, converts some to other substances (one is cholesterol) and sends the rest to fat cells, where they wait until they are needed.
What happens to the protein:
•    It is broken down into building blocks known as peptides.
•    Then, it is further broken down and it becomes amino acids.
•    The amino acids are absorbed through the small intestine's lining and enter the blood stream.
•    From here, some of the amino acids build the body's protein stores.
•    Excess amino acids are converted to fats and sugars and follow the paths described above.
Protein is used for creating, repairing and maintaining tissue, forming blood cells, making antibodies, creating enzymes and hormones that control body functions. Protein is also used for energy. There is a common myth, especially amongst body builders, that eating excess protein creates larger muscles.  Extra protein beyond the daily requirement will not make extra muscle or grow hair faster or protect against diseases.  Protein beyond what is required by the body is either eliminated, or it is turned into fat and stored in fat cells.  Protein requirements vary based upon body size and special needs. To calculate the protein needs of your body, calculate based on the formula of 0,.8 grams of protein for each kilogram of body weight.  To find weight in kilogram, divide weight in pounds by 2.2.  So if you’re bodybuilding, add more protein GRADUALLY, in accordance with your body as you build muscle.
Example:
Persons’s weight = 165 pounds
165 pounds/2.2 pounds per kilogram
75 kilograms X 0.8 grams
= Protein requirement of 60 grams per day.
Exceptions to this are pregnant and nursing women and children who require more for the production of milk and forming new tissue.  Athletes and body builders also require more protein, however, a very common misconception is that they require huge amounts more protein than they normally would get from a regular diet, so they end up consuming too much which over time can have harmful effects on the kidneys. Ever see those guys that are always at the gym walking around with large muscles but it seems there’s a layer of chubbiness that surrounds them no matter how much they keep working out and lifting.  I’ll pretty much bet that if you ask how they eat, they’ll tell you they eat fantastic, protein, protein, protein!  
Guess what people, what the body does not use or excrete, turns to fat! So why consume more than you need? And that holds true for all three rudiments, carbohydrates, fat AND protein.
The best diet is a BALANCED diet.  Eat a variety of foods, include lots of veggies, fruits, whole grains and lean protein.  A balanced diet generally consists of 40% carbohydrates, 30% Protein and 30% fat (mostly not saturated).
