Protiens are the building blocks of your muscles. When you work out, your actually making little tiny tears in your mucles and that's what makes them ache when you're done and also why they seem a little bigger and harder immediatly after you've finished. Protiens are used by your body to "heal" the little tears by filling them in with more muscle tissue and that is how you build larger mucles.\n\nWhen you're finished a hard work out, drinking a protien shake will give your body plenty of what it needs to heal your muscles faster, and you wont experience sore, achey mucsles the next day.

120 - 160 grams of protein.  This will be important in helping to maintain muslce mass, since the body likes to convert glycine (an amino acid) to glucose for fuel when in a gasting state.  There is no easy way to pack this much protein into a single shake, unless it is a really big shake.\n\nI recommend getting the cheapest brand of protein you can find (preferrably derived from milk or egg).  You will probably have to do other things beyond consuming protein to lose weight, but this is probably the amount that you will need to consume.

Based upon my knowledge...you should not gain any weight.  Protein is what will help build muscles.  And for the calorific factor, think about how many calories you burn while running versus your intake against the calories in the protein bar.  I think your OK either way.  Protein bars are healthy.

Generally, you want to eat about 1 gram of protein per pound of body weight if you are trying to gain muscle mass and are working out with weights regularly. Some body builders even double that amount. But if you want to just maintain the muscle you have about half that is okay. Protein is so vital to every thing that goes on in your body. Enzymes, hormones, body cells, bone, skin and muscle are all made up of the amino acids from proteins so plenty of protein is essential but balance that with an equal amount of good carbohydrates to give your body the energy it needs to do all things it does.

hi, don't take any protein formulas that's for sure....\nif you have a balanced diet you need nothing more as it means that you are ingesting all the right amino acids and vitamins. lots of weight exercise will give you what you want. all these people that take protein thinking that it helps them built up their muscles, the only thing that they do is to put a strain on their kidneys. body cannot use more protein just because you are having it. if you think about it, you will see that all these people exercise too much and that is what actually builts muscles and not the protein supplementation. there is a huge number of research on that so play it safe!EXERCISE (weight lifting) and a BALANCED DIET. 2 glasses of milk (300ml x 2) + a portion of fish or meat a day will provide all the protein you need for a day.

You'll want to ensure yourself of amino acid intake that will result in "complete protein" production.  Also, you'll want to ensure yourself of adequate vitamin B intake (these are energy vitamins).\n\nFor complete protein production, mix grains with dried beans -- rice n beans, rice n bread (tortillas, pita bread, etc).  Also, mix pasta with cheese.\n\nYou may want to consider purchasing tablets with vitamins B1,2,3, 6, 12.\n\nIf you will include dairy and egg products in your diet, your protein and vitamin B intake should be okay.

You could eat more protein in your diet. Protien is used to build skin and muscle.

One function of proteins is structural.  They are kind of like the framework of a cell, known as a cytoskeleton.  Proteins also make up structural features such as your hair.  The second function of proteins in the human body is a biochemical function.  Our enzymes are proteins.  Without them we would not be able to digest our food, use the energy we get from food, repair our cells, carry oxygen from the air we breathe around our body, fight off infection, and many, many other things.  Proteins are so important to the human body that the function of our DNA is to code for our proteins!  That's what DNA mostly does, it just tells our body what protiens to make and in what amounts.

Proteins:\nAny of a group of complex organic macromolecules that contain carbon, hydrogen, oxygen, nitrogen, and usually sulfur and are composed of one or more chains of amino acids. Proteins are fundamental components of all living cells and include many substances, such as enzymes, hormones, and antibodies, that are necessary for the proper functioning of an organism. They are essential in the diet of animals for the growth and repair of tissue and can be obtained from foods such as meat, fish, eggs, milk, and legumes.\n\nNucleic Acid:\nAny of a group of organic substances found in the chromosomes of living cells and viruses that play a central role in the storage and replication of hereditary information and in the expression of this information through protein synthesis. In most organisms, nucleic acids occur in combination with proteins; the combined substances are called nucleoproteins. Nucleic acid molecules are complex chains of varying length. The two chief types of nucleic acids are DNA (deoxyribonucleic acid), which carries the hereditary information from generation to generation, and RNA (ribonucleic acid), which delivers the instructions coded in this information to the cell's protein manufacturing sites.\n\nHope tht helped

Proteins are macromolecules. They are constructed from one or more unbranched chains of amino acids; that is, they are polymers. A typical protein contains 200–300 amino acids but some are much smaller (the smallest are often called peptides)\n\nWe know Proteins are Broken down from Protease and can be then broken further down into amino acids.\n\nWhy do we need Proteins for?\nWell ahve a look.\n\nMotion and locomotion of cells and organisms depends on contractile proteins. [Examples: Muscles] \nThe catalysis of all biochemical reactions is done by enzymes, which contain protein. \nThe structure of cells, and the extracellular matrix in which they are embedded, is largely made of protein. [Examples: Collagens] (Plants and many microbes depend more on carbohydrates, e.g., cellulose, for support, but these are synthesized by enzymes.) \nThe transport of materials in body fluids depends of proteins. [See Blood] \nThe receptors for hormones and other signaling molecules are proteins. \nProteins are an essential nutrient for heterotrophs. \nThe transcription factors that turn genes on and off to guide the differentiation of the cell and its later responsiveness to signals reaching it are proteins.\n\n4) Strcuture of a Protein\n\nProteins fold into a variety of 3-dimensional shapes. Experiments to unfold and refold proteins have shown that the amino acid sequence itself contains all the instructions needed for proper folding. Scientists have searched for rules governing folding but have found no reliable way to predict a 3-dimensional structure from a simple sequence.\n\nKnowing a protein's sequence does help, however. Having determined \n\n3) Importance of Proteins\nThere are proteins that build muscle, transport protein that carry nutrients, enzymes that 搄ump start?cellular activity, protein hormones involved in regulating metabolism, structural proteins like collagen, and special proteins needed for antibody production. Proteins are thus involved in all body functions, and are nessacary for health.\n\nProteins are large molecules that are made up of smaller chains of peptides. Peptides are chains of amino acids that are biochemically bonded together. There are about 50 amino acids is a single peptide chain. During normal digestion the proteins we take in are broken down into its simplest form (amino acids). These amino acids are then absorbed by the body and made back into proteins that the body needs. As we saw before proteins are crucial to a variety of body functions and structure. This is why everybody need to include protein foods in their diet\n\n\nSort of answer Your Question?

You might consider the Atkins diet - lots and lots of protein to help build muscle - and maybe doing some work in construction to help build your body up.

I used to use dessicated liver tabs, lean beef and chicken. Protein powders are useful but read the label first and use it sparingly. A good, complete diet should be enough to build muscle without the use of supplemented protien powders.

meats and nuts.  You only want to eat lots of protein when your building muscle.  Otherwise just keep a small amount in your daily diet

Actually, to build muscle mass, you really need more energy in the form of carbohydrates, preferrably complex carbohydrates.  When you stress the muscles, using energy, then new cells are built.  However, just adding protein does not build muscles.  \n\nSo, as a low consumer of meat, you will find plenty of protein in milk, cheese, egg, dried beans and peas (cooked), and nuts.  There is also protein in other vegetable foods like breads, pasta, other grains, and vegetables.  \n\nI would recommend that you enjoy eating and working out, but do not take extra protein pills.  Please do not become engrossed in excess exercise at your age.  You still have some growing to do, and you do not want to stunt any of your growth.  \n\nLenore Hodges, PhD, RD, LD\nRegistered, Licensed Dietitian

If you are doing strength training, you should try to get 1.5 to 2 grams of protein per pound of body weight. Your body uses protein to build the muscles. \n\nSoy and legumes are good sources of protein. If your diet includes dairy products, these are another good source of protein. You should try to get as much of your protein from your diet, and then use powders to supplement (soy powder or whey protein powder).
