What is Protein, and What Does It Do for Your Body?
Let’s start by understanding what protein is.
Along with carbohydrates and fats, protein is a vital macronutrient that plays a unique role in your body because it relies on protein for countless functions.
Made up of smaller units called amino acids, protein serves as the building block for your muscles, tissues, skin, hair, and even your bones and organs.
There are 20 different amino acids, and your body can make some of them on its own. But nine are considered essential amino acids, meaning you need to get them from your diet.
So, what exactly does protein do for your body?
It helps repair and build muscle tissue after lifting weights, which is why it’s often associated with workouts and recovery. But beyond muscle, protein is crucial for almost every biological process.
It supports your immune system by producing antibodies, helps carry oxygen in your blood via hemoglobin, and even assists in producing enzymes and hormones that regulate important bodily functions like metabolism and growth.
As you see, amino acids are beneficial not only for bodybuilding and muscle mass but for many other body functions. So now, let’s look into the health benefits of protein.
The Benefits of Protein Intake
Now that you’re aware that protein is much more than just a muscle-builder, let’s break down some of the most important roles and wide-ranging benefits for your health of this nutritional powerhouse:
Building Blocks of Body Tissue
Protein and amino acids provide the fundamental building blocks your body needs to repair and build tissues. Every cell in your body contains protein, which helps to repair damaged tissues, maintain muscle mass, and support growth.
This makes protein especially crucial if you want to gain muscle or recover after exercise or injury – as well as for maintaining healthy skin, hair, nails, and organs.
Role in Hormone and Enzyme Production
Proteins are involved in the creation of essential hormones and enzymes.
Why does that matter? Because your hormones regulate various processes in your body, like metabolism, growth, and mood, while enzymes facilitate chemical reactions, such as breaking down food and synthesizing DNA.
Without enough protein, these critical processes could become less efficient, leading to a range of health issues, including:
- weight gain
- fatigue
- hormonal imbalances
- poor immune function
- delayed growth and development in children
Boosting Metabolism and Increasing Fat-Burning
Protein and amino acids can help boost your metabolism by needing more energy for digestion – a process called the thermic effect of food (TEF).
This effect makes your body work harder to break down protein than it does for fats or carbohydrates, leading to a temporary increase in calorie burning.
Additionally, high protein intake can help preserve lean muscle mass, which increases your resting metabolism and aids fat loss over time.
Helping You Feel Fuller for Longer
Protein takes longer to digest compared to carbohydrates and fats. This helps you feel full and satisfied for a longer period after eating. It can therefore reduce the likelihood of you reaching for a snack between meals!
In addition, essential amino acids also influence the release of appetite-regulating hormones like ghrelin (which increases hunger) and peptide YY (which promotes fullness). So, eating a high protein meal can lower ghrelin levels and increase peptide YY. This reduces hunger and prolongs your feeling of satiety.
And finally, protein helps stabilize your blood sugar by slowing down the absorption of glucose from carbs. This reduces blood sugar spikes and crashes, which can trigger hunger and cravings.
The combination of slower digestion, hormonal regulation, and lower blood pressure makes protein an excellent choice for keeping you satiated and managing calorie intake more effectively.
Strengthening Immune Function
Another essential benefit of protein intake is boosting your immune system.
Antibodies, which protect your body against viruses and bacteria, are made from proteins. This means that, when you consume protein properly, your immune system is better equipped to fight off infections and illnesses. You stay healthier.
Enhancing Muscle Mass and Strength
Protein is critical for muscle growth and maintenance. When you engage in strength training or other physical activities, your muscles undergo wear and tear.
But protein helps repair muscle fibers, leading to stronger and more defined muscles over time. So, consuming enough protein is particularly important for athletes or anyone looking to gain muscle mass and enhance strength.
Improving Bone Health
Protein plays a significant role in maintaining healthy bones. Studies have shown that higher protein intake is associated with better bone density and a lower risk of fractures, especially as you age.
Higher protein intake also supports the structure and strength of your bones by helping your body absorb calcium and other minerals more effectively. This contributes to your long-term bone health.
Now that you know the health benefits of protein, let’s learn how to leverage it with your diet.
The Importance of Protein in a Balanced Diet
It’s becoming obvious that protein is one of the most important nutrients for maintaining a healthy body. It plays a critical role in everything from muscle repair to hormone regulation.
So, whether you’re aiming to enhance muscles, manage your weight, or simply support your overall health, getting the right amount and type of protein can make all the difference. That’s why you should aim for a healthy diet rich in protein and other essential nutrients.
What happens to your body when you eat more protein?
When you increase your protein intake, you may notice several positive changes.
As mentioned, you’ll likely feel fuller for longer after meals, which can help curb overeating and promote weight loss or maintenance. You may also see improvements in muscle mass and strength, especially if you’re active. Enhanced muscle repair means quicker recovery from exercise or injury.
Additionally, you might experience a boost in metabolism due to the thermic effect of food, where your body burns more calories digesting protein, which supports weight loss.
Over time, a consistent intake of adequate protein can support healthy aging by preserving your muscle mass, reducing your risk of sarcopenia (muscle loss with age), and maintaining your bone density.
Having more protein in your diet can also contribute to lowering your blood pressure, improving your cardiovascular health, and boosting your immune system.
But how to identify the right amount? Let’s check it out.
How Much Protein Do You Need Per Day?
The ideal amount of protein depends on several factors, including age, gender, activity level, and medical history.
In general, however, most Americans eat more than enough protein to meet – or exceed – their needs. But more than half fail to meet beneficial sub-group protein intake from nuts, seeds, and soy products.
But what’s the official recommendation?
The recommended daily allowance (RDA) for most people is around 0.8 grams of protein per kilogram (or approximately 7 grams for every 20 pounds of body weight).
That means about 46 grams of protein for the average woman and 56 grams for the average man. Or just aim for 10 to 35% of your daily calorie intake in the form of protein.
So, do you have enough protein? What happens if you overpass these recommendations? Let’s find out.
Pros and Cons of Protein Diet
We’ve looked at the pros of eating protein. Here are some cons of having more than enough protein and the potential risks of high protein diets.
Despite some trending fad diets claiming that a high protein intake is beneficial for your health, consuming too much protein doesn’t come without risks. The main ones are:
Kidney Strain: Very high protein diets, especially if you have pre-existing kidney issues, can strain your kidneys.
Nutrient Imbalance: A focus on a high protein diet can sometimes lead to insufficient intake of other important nutrients like fiber and healthy fats, leading to malnutrition and constipation.
Health Benefits of High Protein, Low Carb Diet
If your goal is weight loss, you can benefit from a high protein, low carb diet, which promotes satiety and stabilizes blood sugar levels.
By reducing carbohydrates and increasing dietary protein (while not surpassing the recommended daily intake!), your body shifts to burning fat for energy. This can lead to more effective fat loss when you want to lose weight.
This type of diet may also improve your heart health by reducing triglycerides and increasing HDL (good) cholesterol levels.
The Best Protein Sources to Power Your Diet
When it comes to fueling your body with the right nutrients and essential amino acids, the key is to select high-quality dietary protein sources.
By choosing a variety of nutrient-dense and protein-rich foods – with both plant-based and animal-based protein sources – you can ensure you’re meeting your protein needs while also benefiting from essential vitamins, minerals, and other nutrients.
To help you make informed choices, we’ve listed below some of the best protein sources available for you to add to your protein-rich diet for optimal health and vitality, perhaps also to lose weight.
Plant-Based
- Lentils
- Beans
- Chickpeas
- Tofu
- Tempeh
- Quinoa
- Nuts
Animal-Based
- Lean meats like chicken and turkey
- Fish (especially fatty fish like salmon),
- Eggs and dairy products, such as yogurt and cheese
What About the Benefits of Protein Shakes for Females?
Protein powders and shakes can also be very beneficial in a healthy diet, especially for certain individuals or specific situations, like athletes or women with busy lifestyles.
But for women, shakes can also be a convenient and effective way to consume more protein and reach your daily needs – especially if you’re always on the go, with work or children.
If you’re aiming to lose weight, support muscle tone, or age healthily, protein powders offer you an easy, versatile option, promoting satiety without excess calories. They’re also great for post-workout recovery, helping to repair muscle and reduce soreness after lifting weights.
Other pros include:
- Targeted nutrient intake
- Support for muscle recovery
- A variety of options to choose from
- Satiety and weight management
- Protein’s nutrient density
However, it’s important to note that while protein shakes can be beneficial, it’s essential to choose high-quality products without added sugars, artificial ingredients, or fillers.
Additionally, whole food sources should still form the foundation of your diet. We recommend protein shakes as a supplement rather than a primary source of nutrition.
Finally, remember that if you have specific health conditions, such as kidney issues, you should consult with a healthcare professional before significantly increasing your protein intake.
How to Choose the Right Protein Sources for Your Diet
The right protein sources depend on your dietary preferences and health goals. If you’re focusing on heart health and lower blood pressure, plant-based proteins or lean meats and fish may be the best choice.
For muscle building, a mix of both plant and animal protein can provide a broader range of essential amino acids.
If you’re vegetarian or vegan, combining different plant proteins (e.g., beans and rice) and a shake makes for a high protein breakfast and ensures you get a complete protein profile.
