Benefit #3 Protein Aids With Muscle Recovery And Growth

How Does Protein Build Muscle?

Not only does eating protein help prevent muscle breakdown, but it can also help build muscles. Combining regular activity and exercise with protein intake promotes muscle growth.

High-quality proteins contain all of the essential amino acids and are rich in branched-chain amino acids . Leucine, one of these BCAAs, plays a major role in promoting muscle growth and recovery after resistance and endurance exercise. These high-quality proteins exist in animal-based protein foods such as lean poultry, beef, fish, dairy, egg products, and whole eggs.

Protein shakes are extremely convenient, making them useful for active individuals and athletes who are constantly on the go. If choosing a protein powder supplement, whey protein and plant-based proteins such as soy or pea have been shown to most effectively promote muscle growth and recovery.

When Does The Body Use Protein As An Energy Source

Protein can be metabolized and used as an energy source for the body, but its not the preferred source of energy.

Our bodies are all about efficiency, and carbohydrates are our primary source of food energy because theyre fast-acting and can be easily broken down into usable glucose.

Only a small amount of carbohydrates can be stored in the liver and muscles as glycogen, a form of glucose stored for energy. So, in the absence of enough carbs, our bodys next preferred energy source is fats.

Fats are more energy-rich than carbs, but they take longer and are more difficult for the body to convert to usable energy. This explains why you might feel like you hit a wall 60-90 minutes into a tough workout when your glycogen stores become depleted.

Under ordinary circumstances, our bodies only use protein for a small amount of daily energy. Protein is meant for growth and repair and cannot be stored away like fat and glycogen. In some situations, such as when we eat too few calories, restrict carbohydrates, or during later stages of endurance exercise, muscle is broken down into amino acids and converted to glucose that can be used as fuel for the body and brain.

At a certain point, trying to decrease body fat by restricting calories or increasing exercise also means sacrificing some muscle as the body works to keep glucose at a healthy level.

Where Does Protein Come From

The healthiest protein options are plant sources, such as soy, nuts, seeds, beans and lentils lean meats, such as skinless, white-meat chicken or turkey a variety of fish or seafood egg whites or low-fat dairy.

Meet your dietary protein needs with these whole foods versus supplements, which are no more effective than food as long as energy intake is adequate for building lean mass.

Manufactured foods don’t contain everything you need from food, and manufacturers do not know everything that should be in food.

What Foods Are High In Protein

Protein from food comes from plant and animal sources. Although animal products contain higher protein than whole grains and vegetables, many plant-based protein sources can give the desired part of the daily protein requirement.

So, people who eat plant foods or follow a vegetarian or a vegan diet must ensure that their protein needs are still met.

How Protein Benefits The Body

Best Diet for Muscles Buildings

Almost everyone can agree on the importance of protein. Because of this, cases of protein deficiency are very low. Protein benefits the body in many ways and is very crucial to good health. Biologically, proteins are made up of amino acids that join together in the form of a chain to form a larger compound. The work of proteins lies mainly in the cells.Below are some ways protein benefits the body.

Protein Cuts Cravings And Reduces Desire For Late

Cravings are the dieters worst enemy.

They are one of the biggest reasons why people tend to fail on their diets.

Another major problem is late-night snacking. Many people who have a tendency to gain weight get cravings at night, so they snack in the evening. These calories are added on top of all the calories they ate during the day.

Interestingly, protein can have a powerful effect on both cravings and the desire to snack at night.

This graph is from a study comparing a high-protein diet and a normal-protein diet in overweight men (

The high-protein group is the blue bar, while the normal-protein group is the red bar.

In this study, protein at 25% of calories reduced cravings by 60% and cut the desire for late-night snacking by half!

Breakfast may be the most important meal to load up on the protein. In one study in teenage girls, a high-protein breakfast significantly reduced cravings .

Bottom Line:

Eating more protein can lead to major reductions in cravings and the desire to snack late at night. These changes should make it much easier to stick to a healthy diet.

Whey Protein Promotes Muscle Growth

Muscle mass naturally declines with age.

This usually leads to fat gain and raises the risk of many chronic diseases.

However, this adverse change in body composition can be partly slowed, prevented, or reversed with a combination of strength training and adequate diet.

Strength training, coupled with the consumption of high protein foods or protein supplements, has been shown to be an effective preventive strategy .

Particularly effective are high quality protein sources, such as whey.

Whey is rich in a branched-chain amino acid called leucine. Leucine is the most growth-promoting of the amino acids .

For this reason, whey protein is effective for the prevention of age-related muscle loss, as well as for improved strength .

For muscle growth, some studies show that whey protein may be slightly better than other types of protein, such as casein or soy (

16 ).

A limited number of human studies have investigated the effect of whey proteins on blood pressure, and many experts consider the evidence to be inconclusive.

One study in overweight individuals showed that whey protein supplementation, 54 g/day for 12 weeks, lowered systolic blood pressure by 4%. Other milk proteins had similar effects .

This is supported by another study that found significant effects when participants were given whey protein concentrate for 6 weeks.

However, blood pressure decreased only in those that had high or slightly elevated blood pressure to begin with .

Helps Build Muscle Mass

It helps build and maintain muscle mass and strength. When your metabolism works efficiently, more muscles are formed. At age 40, you may experience loss of muscle mass and strength which requires eating protein more and reducing calorie intake.

Remember:

People who exercise vigorously to gain skeletal muscle mass do not need extra protein. High protein diets do not cause muscle mass. The stimulation of muscle tissue causes muscle mass through exercise, which leads to muscle growth, not extra dietary protein.

Staying physically active is essential, including working out in gyms or engaging in resistance exercise.

To help prevent losing muscle mass, known as sarcopenia, you need more protein to gain muscle. Some who have a hard time taking in more protein resort to dietary protein thats fine as long as its not too much. Very high protein diets are dangerous.

DO YOU KNOW THAT

A study published in the American Journal of Clinical Nutrition showed that a large single dose of 25 g of protein after exercise could increase muscle protein synthesis.

This finding could explain why protein shakes are often associated with those who work out, body builders, and gym rats.

Does Protein Build Muscle

Does protein build muscle? Here are all of your protein questions, answered

Does protein build muscle? The answer to this question is a resounding, yes. Muscle tissue is composed of a repeating structure of two protein filaments: myosin and actin. Myosin and actin filaments interact with each other to initiate muscle contractions and, over time, mechanical stress caused by constant movement will damage these protein filaments.

As a result, your muscles need a daily supply of protein to rebuild themselves and stay functional. Mechanical stress from weight training is strenuous enough to make your muscles bigger and stronger, which is why bodybuilders tend to train with extremely heavy weights. Its also why they may use supplements like the best protein powder and the best protein bars its how they ensure their bodies contain enough protein building blocks to maintain their sculpted physique.

But it may take more than just drinking protein shakes to achieve the desired musculature. Many different factors affect the strength and size of your muscle fiber types , including the type and amount of protein you consume. So if you want to know how to gain muscle , read on. Here, well discuss the science behind effective bodybuilding and help to answer all of your protein questions.

Whey Protein May Be Beneficial For Inflammatory Bowel Disease

Inflammatory bowel disease is a condition characterized by chronic inflammation in the lining of the digestive tract. It is a collective term for Crohns disease and ulcerative colitis.

In both rodents and humans, whey protein supplementation has been found to have beneficial effects on IBD .

However, the available evidence is weak and further studies are needed before any strong claims can be made.

Summary

Whey protein supplements may have beneficial effects on IBD.

What Do Proteins Do For The Body

Our bodies are made up of thousands of different proteins, each with a specific function. They make up the structural components of our cells and tissues as well as many enzymes, hormones and the active proteins secreted from immune cells .

These body proteins are continually being repaired and replaced throughout our lives. This process requires a continuous supply of amino acids. Although some amino acids can be recycled from the breakdown of old body proteins, this process is imperfect. This means we must eat dietary protein to keep up with our bodys amino acid demand.

As protein is essential for cell and tissue growth, adequate intake of protein is particularly important during periods of rapid growth or increased demand, such as childhood, adolescence, pregnancy, and breastfeeding.1

Protein Deficiency Can Lead To Malnutrition

Protein deficiency can lead to malnutrition, such as kwashiorkor and marasmus. Both of these conditions are life-threatening.

This protein deficiency happens if a person has a health condition such as an eating disorder like anorexia nervosa.

An energy deficit due to the deficiencies of many micronutrients is called Protein-energy undernutrition . This condition can be sudden caused by total starvation or gradual.

Why We Even Need Protein

Whey Protein

That building block nickname is no exaggeration. The stuff is an integral component of every cell in your body, including, yes, your muscles.

If we don’t get enough protein, our bodies actually wont be able to rebuild properly and well start to lose muscle mass, Colleen Tewksbury, Ph.D., M.P.H., R.D., senior research investigator and bariatric program manager at Penn Medicine and president of the Pennsylvania Academy of Nutrition and Dietetics, tells SELF.

Protein helps repair the microtears that occur in your muscle fibers when theyre strained during exercise, the American College of Exercise explains. That process of damage and repair is what maintains and grows your muscle mass.

But protein is not just important for people who work out: In addition to muscle growth and repair, protein is essential to the growth and repair of virtually all cells and body tissuesfrom your skin, hair, and nails to your bones, organs, and bodily fluids, according to the FDA. Thats why its especially important to get enough of it during developmental periods like childhood and adolescence.

Protein also plays a role in crucial bodily functions like blood clotting, immune system response, vision, fluid balance, and the production of various enzymes and hormones, per the FDA. And because it contains calories, it can provide the body energy for storage or use.

What Does Zinc Do To Proteins

Zinc is an essential mineral that is found in many foods. It is necessary for the proper functioning of many enzymes and is involved in the metabolism of proteins. Zinc plays a role in the development and function of cells and is necessary for the proper healing of wounds. It is also involved in the sense of taste and smell.

In eukaryotic organisms, zinc ranks second to iron as the second most abundant trace metal. As a result, it is necessary for critical catalytic functions in enzymes , as well as stabilization and folding of protein subdomains. As iron is removed from hemoglobin, zinc becomes the most abundant trace metal in the human body. The protein is shown in the illustration in Silico and in Vitro Analysis of Mycobacterium avium subsp. Paratuberculosis is a disease that develops as a result of a parasitic infection.

How Much Protein Does The Body Need

The daily maximum amount the body can use for protein synthesis is said to be around 2 grams per 1 kilogram of body weight. Consuming more protein will not increase synthesis, but increase the amount consumed as energy, and lead to an increase in body fat. Too much protein can also burden the liver and kidneys.

The daily maximum amount used for protein synthesis is around 2g per 1kg of body weight

Therefore, it is important to adjust the amount of protein you consume.If you eat three well balanced meals a day, you should easily be able to acquire the amount of protein your body needs. The important thing is not only how much you eat, but also when you eat it.

Protein Preserves Lean Body Mass

In addition, protein has another benefit on weight loss: it helps preserve lean body mass during periods of caloric restriction.

One study compared the effect of low protein intake to high protein intake on lean body mass over a short term caloric deficit. On average, the low protein group lost about 1.6 kilograms of muscle mass while the high protein group only lost 0.3 kg of muscle mass .

Another similar study compared 0.8 g/kg per day against 1.6 g/kg per day and 2.4 g/kg per day and found that the two higher intakes spared more lean body mass than the 0.8 g/kg per day diet. They also found that there was no real benefit to 2.4 g/kg per day over 1.6 g/kg per day .

Currently, most evidence suggests that ~1.6 grams of protein per kilogram, or .73 grams of protein per pound is a recommended daily target for protein intake to spare lean body mass loss during periods of weight loss.

The Health Benefits Of Protein

What are proteins? – Healthy Eating for Kids

Protein gives you the energy to get up and goand keep going. While too much protein can be harmful to people with kidney disease, diabetes, and some other conditions, eating the right amount of high-quality protein:

  • Keeps your immune system functioning properly, maintains heart health and your respiratory system, and speeds recovery after exercise.
  • Is vital to the growth and development of children and for maintaining health in your senior years.
  • Can help reduce your risk for diabetes and cardiovascular disease.
  • Can help you think clearly and may improve recall.
  • Can improve your mood and boost your resistance to stress, anxiety, and depression.
  • May help you maintain a healthy weight by curbing appetite, making you feel full longer, and fueling you with extra energy for exercising.

As well as being imperative to feeling healthy and energetic, protein is also important to the way you look. Eating high-quality protein can help you maintain healthy skin, nails, and hair, build muscle, and maintain lean body mass while dieting.

While most people eating a Western diet get a sufficient quantity of protein each day, many of us are not getting the quality of protein we need.

Protein Is Hard To Store As Body Fat

During periods of weight loss, there are often times where more energy is consumed than expended. As such, minimizing how much of that excess energy is stored as fat is important.

The body processes the three different macronutrients in very different ways.

Leaving out a lot of jargon and mumbo jumbo, in order for protein to be stored as fat, it goes through a much different biochemical process than either carbohydrates or protein.

This process makes it much harder for protein to store as body fat.

One study found that protein is stored as body fat with roughly 66% efficiency, while carbohydrates store with 80% efficiency and fats store at 96% efficiency .

During weight loss, overeating protein results in much less stored body fat than overeating on carbohydrates or fat. If you are looking for ways to lose weight fast, consuming protein is a great option!

Why Does Your Body Need So Much Dairy Food

There are lots of essential nutrients in dairy. Each time you eat or drink dairy, you are giving your body calcium, iodine, vitamin A, vitamin D, riboflavin, vitamin B12 and zinc.

Calcium and vitamin D help your body build strong dense bones as you grow, and they keep your bones strong and healthy as you get older. Most adults need 1,000 milligrams of calcium every day. This increases to 1,300 milligrams for women aged over 50 and men aged over 70.

Not having enough calcium in your diet may increase your risk of osteoporosis. Osteoporosis is a disease of the bones, where they become brittle and weak and can break easily.
