Why We Even Need 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.
Youre Not Eating Right
Are there days when you forget to eat because there is too much to do? Eating too little leaves you feeling weak. But the same thing goes for eating too much, choosing unhealthy foods, or following the wrong diet. If we consume a lot of simple carbohydrates , this can rob us of energy. Why? These foods provide the body with empty calories. Your blood sugar levels rise rapidly for a short time because the pancreas is pumping out insulin like crazy. But soon they will fall as fast as they rose and this makes you sluggish. Fatty foods or meals place great demands on your body. Therefore, you should try to eat as balanced a diet as possible.
Another cause of fatigue could be that you are drinking too much coffee. Yes, it can make you tired! Its true that coffee initially stimulates the production of adrenaline, but this only lasts a short while, leaving you feeling more tired afterwards than you did before the cup of coffee. A lot doesnt always mean a lot more energy.
Note: There are some foods that help you sleep because they contain tryptophan. If you eat large quantities of these foods during the day, the sleep-inducing protein building block will make you feel sleepy.
Are You Getting Enough Protein 7 Ways To Eat More Every Day
Protein helps you build strong muscles, but it also helps boost your energy and regulate your appetite.
Protein has long held a place in the hearts of body builders, athletes and fitness enthusiasts for its crucial role in muscle recovery, growth and strength. It’s not just those groups who need protein, though: The average adult should get about 0.8 to 1 gram of protein per kilogram of body weight — if you weigh 150 pounds , you should aim for about 55 to 68 grams of protein per day.
People who lift weights, compete in sports or work laborious jobs may benefit from eating more protein than the current 0.8 gram per kilogram of bodyweight recommendation. Older adults, especially those at risk for sarcopenia may also benefit from more protein. Try this DRI calculator from the USDA to find out approximately how much protein you need.

How Much Do You Need
The U.S. Dietary Guidelines state that an adult man should take in a minimum of 10% of his daily calories from protein. The body breaks the protein down into amino acids andamong other thingsuses them to build muscle. Any protein left over is available to fuel energy needs. Each gram of protein you eat contains 4 calories.
Guidelines also say that the healthy range for protein extends up to 35% of daily calories. In practice, it can be difficult to consume that much protein every day without resorting to eating a lot of meat and other animal foods or relying on protein supplement products.
Most People Eat Too Much Protein But Certain People Need More
Most people overestimate the amount of protein they need every day, said registered dietitian and certified personal trainer Lauren Cadillac. Sedentary, generally healthy adults only really need about 0.8 to 1 gram of protein per kilogram of body weight, she explained. That’s around 60 grams a day for a 150-pound person a full chicken breast already puts you over 50 grams, according to the U.S. Department of Agriculture.
But the more active you are, the more protein you need, Cadillac said. Protein requirements may go as high as 1.7 to 2 grams per kilogram of body weight, depending on your sport or activity level, she added.
Pregnant women also tend to need more protein, as do folks who are sick or recovering from surgery, Cadillac said. If you’re losing protein for some other reason like chronic physical stress or poor digestion, you should up your intake too, she said.

Look Out For These Red Flags
Protein needs vary from one athlete to another, so it can be hard to know if youre getting enough of this macronutrient. If youre spending most of your gym time in the weight room, your protein needs will tip to the higher end of the spectrum. But knowing exactly how much protein is enough can be tricky.
Scientists say that following certain recommended guidelines isnt necessarily the way to go.
There is a good rationale for recommending to athletes protein intakes that are higher than the RDA, say scientists who published a paper in the Journal of Sports Sciences. The authors recommend an intake of protein 1.3g1.8g per kilogram per day to maximize muscle protein synthesis. They add that consuming more protein during times of intense training or calorie restriction may be helpful as well.
But what happens if your daily protein intake falls short? These are some of the most common signs that youre not getting enough protein.

Not All Food Proteins Are The Same
Protein is made up of amino acids. These amino acids are often referred to as building blocks because the small units are assembled in different sequences and lengths to build different proteins. So this means that different foods contain different proteins .
There are 20 amino acids and nine of these are called essential. This is because your body cannot make them .
Protein that comes from animal sources is known as complete protein . It contains all the essential amino acids. On the flip side, plant proteins are considered incomplete proteins. They are missing at least one of the essential amino acids. The only exception to this is soybeans, which are a complete protein. What this means is that not all proteins are equal. And if you do not eat meat, poultry, fish, eggs or dairy, you have to manage your protein intake to make sure your body gets the full range of essential amino acids. But as long as you eat a wide variety of foods, you can usually make complete proteins.

Bone Injuries And Fractures
We require amino acids to build and repair not just our muscles but also our bones. Building bone density is closely related to how much muscle you have, as bones get stronger when muscle mass increases . Insufficient protein intake has been linked to lower bone mineral density, decreased bone strength, increased risk of fractures, weakenedjoints, and in extreme cases, Osteopenia.

Q: As a fairly new vegetarian, Im not sure Im getting enough protein. Is there a formula to figure out how much I need, and is age ever a factor?
A: Protein is the major component of all of your bodys cells, and youre right, its important to make sure youre getting enough. Recent research indicates that we may need more than previously thought. The recommended dietary allowance for all adults is 0.37 grams of protein per pound of bodyweight, or about 15 percent of your daily calories.
But you probably need more if you exercise, if youre dieting, and as you age. One dramatic study of 855 people found that those who ate just the RDA of protein had alarming bone losses compared to those who ate more than the RDA. Those who ate the least protein lost the most bone mass4 percent in four years. People who ate the most protein had the smallest lossesless than 1.5 percent in four years, reported the Journal of Bone and Mineral Research in 2000. Although the study was done on older men and women, the results may be important for all adults.
When youre young, you need protein to build bone. After age 30, you need it to keep bone from being lost, says Kathleen Tucker, associate professor of Nutritional Epidemiology at Tufts University. Keeping bones strong is a life-long effort.

What Protein Actually Is
Protein is one of the three macronutrients . Unlike carbs and fat, protein is not usually a major energy source, although we definitely get some of that from itprotein provides four calories per gram. But protein is often referred to as a building block in the body because of its central role in growth and development.
Almost all animal-derived productsmeat, poultry, eggs, dairy, fishcontain a significant amount of protein, so they get labeled as protein sources when were talking about our diets and nutrition. But protein is also present in a lot of plant-based foods. Theres a good amount in beans, peas, nuts, and seeds, for instance, while vegetables and grains generally contain smaller amounts, according to the U.S. Food and Drug Administration . Whole grains will have more protein than refined grains, though, which are missing the part of the grain that often supplies a lot of the protein content, as SELF previously reported.
Proteins are made of small units called amino acids. There are 20 different amino acids in total, which can be broken down into two main groups, per the FDA. Nine of the 20 are what are referred to as essential amino acids, meaning that the body is unable to produce them itself and so we must get them from food. The other 11 are nonessential because the body is able to synthesize them out of the essential amino acids or the normal process of breaking down proteins, according to the U.S. National Library of Medicine.
Weak Nails Skin & Hair
If you have weak and brittle nails, skin that is dry and flaky, or hair that is brittle and thinning, these may be early signs that your body is not getting enough protein. Skin is made of proteins such as keratin, collagen, and elastin, and hair is made up of keratin. When these proteins are lacking in the diet, your nails, skin, and hair pay the price.

What Happens In Your Body When You Eat Protein
Its not like you eat a piece of chicken and that protein goes directly to your biceps. Dietary protein gets broken down and reassembled into the various kinds of proteins that exist in the body. No matter what kind of protein youre eatingplant or animal, complete or incompleteyour bodys first objective is to break it back down into all the different amino acid units it was assembled from, Dr. Tewksbury explains, through the digestive process.
Then those little singular amino acids get reconfigured into whatever kind of protein your body needs. For instance, some proteins in the body make up antibodies that help the immune system fight bacteria and viruses. Others help with DNA synthesis, chemical reactions, or transporting other molecules, the National Institute of General Medical Sciences explains.
Eat Your Protein First
When eating a meal, eat the protein source first, especially before you get to the starches.
Protein increases the production of peptide YY , a gut hormone that makes you feel full and satisfied .
In addition, a high protein intake decreases levels of ghrelin, the hunger hormone, and increases your metabolic rate after eating and during sleep .
Whats more, eating protein first can help keep your blood sugar and insulin levels from rising too high after a meal.
In one small study, people with type 2 diabetes were served identical meals on different days. Blood sugar and insulin rose significantly less when they consumed protein and vegetables before eating high carb foods, compared with when the order was reversed .
Eating protein first at meals can help you feel full and keep your blood sugar and insulin levels from rising too high.

What We All Need To Consider About Protein
This advice isnt just for plant-based eaters, but for everyone else too. The funny thing is, too much protein actually isnt beneficial. Animal protein raises insulin in the body which contributes to diabetes and high blood sugar. While its necessary to get enough protein, you obtain plenty that your body needs just from eating plant-based foods. Even those that arent technically vegan or vegetarian could be eating foods that dont support their protein needs. Ironically, if someone eats a 100 percent whole foods plant-based diet or even an 80 percent whole foods plant-based diet, theyll get more quality protein than someone eating the Standard American Diet of cheap processed cereal, junk food cookies, frozen dinners, and fast food.
However, a diet of fruits and veggies alone wont give you all the protein you need. You do need some type of grains, nuts, seeds, or beans, even if theyre in small amounts. These foods provide more protein, and though leafy greens have plenty, most people need another source.
Protein is made of amino acids so when youre lacking in protein, youre really just lacking in amino acids Plants are packed with amino acids that can give you what you need. You should also consider if youre having trouble absorbing the nutrients from your foods, which could indicate a case of malabsorptio
How To Get Enough Protein On A Vegan Diet

Protein Shakes Powders And Supplements
If youre not getting enough protein in your diet, are protein shakes, powders and supplements a good idea? Unless you are exercising or training at the level of an athlete, the simple answer is probably not.
Most of us get more than enough protein through the food we eat. And any protein we eat on top of what our body needs will either be excreted from our body as waste, or stored as weight gain! Also, having too much protein on top of what our body needs can be damaging to our kidneys.
The best way for you to get the protein you need is to eat a wide variety of lean protein as part of a balanced diet. But if you are still interested in using protein shakes, powders and supplements, the best place to start is to talk to your doctor.
Am I Getting Enough Protein In My Diet
Meeting protein requirements is a common concern for many of my clients.
Reasons for concern often include:
Building lean muscle
Following a vegan/vegetarian/”flexitarian” diet
The World Health Organisation and numerous countries have formulated macronutrient recommendations for protein ranging between 10 and 35% of total caloric intake. The distribution of macronutrients should be individualised within these recommended ranges and should be based on the needs and preferences of individuals.
Why is protein so important?
1. Muscle building and repair
High quality proteins including lean meat, skinless chicken, fish, eggs, low-fat or fat-free dairy products and a combination of plant proteins are important in the diet to provide essential amino acids necessary for building and repairing muscle tissue.
2. Vitamins and minerals
Proteins are also good sources of vitamins and minerals such as vitamin A , many of the B group vitamins , iron and zinc . Fish oil from salmon, mackarel, herring, anchovies and sardines is an important source of omega-3 PUFAs including EPA and DHA which contribute to neurodevelopment and cardiovascular health.
3. Fullness and blood sugar stability
What types of proteins should we be choosing?
An additional benefit of plant-based proteins are that they are also generally more affordable than animal protein sources.
