Why You Need Protein

All your food consists of three macronutrients: protein, carbohydrates, and fat. Macronutrients combine to influence your health and provide energy. (1) 

You need all three to fuel your health and workouts, but we’re here for muscle hypertrophy. When it comes to training, you need protein to help you build muscle mass and lose body fat. Eating a healthy diet packed with protein also influences your heart and bone health while boosting your immune system. Let’s break it down.

Helps Build Muscle Mass

Strength athletes are so fond of protein for a reason. This macronutrient helps build muscle mass when paired with resistance training. Here’s how it works. 

Twenty amino acids, often called building blocks, make up muscle protein. Eleven amino acids are non-essential, and the remaining nine are essential amino acids. Your body cannot make them on its own, so you need to get them through your diet as complete protein sources. All twenty amino acids are necessary for hypertrophy. (2)

When you’re in the gym lifting weights, you’re breaking down your muscle fibers. When you eat high-protein foods, you’re consuming dietary protein that helps repair and regenerate your muscle fibers after all those intense leg exercises on your favorite training day of the week. This process leads to muscle protein synthesis — or building muscle mass. (3)(4)

Resistance training is half of the equation, but your body needs protein to maximize your hard-earned gains. 

Helps With Fat Loss

Whether you have a weight loss goal or you’re a bodybuilder on a weight cut, protein will help you with fat loss. Feeling full from your food can help you stay on track when you’re reducing your calories or portions. Protein is the most satiating macronutrient, so packing your meals with it can help you feel full between meals. (5)

Eating a high-protein diet also increases thermogenesis, meaning your body has to work harder to digest your food, slightly increasing your total daily energy expenditure (TDEE). Complete protein sources may have a higher thermic effect, increasing your TDEE even more. (5)(6)

Lastly, a high-protein diet and resistance training during weight loss can help your body preserve lean muscle mass. Some people can theoretically lose weight by reducing their calories or portions, but they may also lose muscle. Keeping your protein high and lifting weights is the key to maintaining muscle mass while losing body fat. (5)

Improves Heart Health

Athletes need a strong heart for tough HIIT workouts — AKA, high-intensity interval training sessions. Healthy eating and regular exercise are fundamental to strong cardiovascular health. Getting enough protein can help lower your risk of high blood pressure, high cholesterol, and heart disease. (7)

The sources of protein you choose matter, too. A 2020 meta-analysis examined the link between different types of protein and cardiovascular (CV) diseases. They found that plant-based protein may be associated with a lower risk of CV diseases. (8)

It doesn’t mean you have to give up all meat — but it’s all the more reason to add some of our high-protein vegetables to your diet.

Boosts Bone Health

What else does an athlete need beyond solid muscles and a healthy heart? Strong bones. 

You may think of vitamin D and calcium as the nutrients associated with bone health, but protein is also essential. Research shows that protein enhances IGF-1, a growth hormone that influences bone development. In multiple clinical trials, low protein intake has been associated with low bone health. (9)

Consuming enough protein can also help prevent osteoporosis, a condition where you lose bone mass as you age. Older adults, especially cisgender women, are more likely to develop it. Osteoporosis can also increase your risk of fractures. (9)

Health professionals recommend getting plenty of protein, vitamin D, and calcium in your diet, along with resistance training and weight-bearing cardio workouts, to prevent osteoporosis. 

Boosts Immune System

It has been well-established that eating a diet low in protein can weaken your immune system. The amino acids in protein directly impact your immune system — particularly arginine, glutamine, and cysteine. (10)

Consuming complete protein sources will give you all the amino acids your body needs to fight off illnesses. Eating protein-rich vegetables will also give you micronutrients and antioxidants, which can help strengthen your immune cells. (11)

Can You Get Adequate Protein From Vegetables?

Yes, you can reach your protein intake goals through high-protein vegetables alone. Plenty of vegetarian and vegan athletes build muscle through plant-based protein. Whether you’re looking to stop eating animal products or just want to add more plants to your diet, you’ll just need to make some adjustments.

Sure, getting 30 grams of protein through a single serving of chicken breast may be quicker than countless servings of spinach, but you can get creative. Combining multiple high-protein vegetables into stews or a stir-fry can increase the protein content of your plant-based dish.

Dietitians recommend getting the bulk of your nutrients through food sources, but you can add supplements if you struggle to get enough protein. Making shakes with a high-quality vegan protein powder can help you boost your intake. Soy protein powder is a great choice. It’s a complete protein source and contains all the essential amino acids you need to build muscle.

How Much Protein Do You Need Daily?

Now that you know how much protein you can get from veggies, how much do you need daily?

As a minimum requirement for bodily functions, the Food and Drug Administration (FDA) recommends 50 grams of protein per day for adults. (13)

However, active people need more than 50 grams. The amount of protein you need may vary based on your body, age, activity level, and fitness goals. 

Check out BarBend’s protein intake calculator to input your stats and get personalized protein needs.

The American College of Sports Medicine (ACSM) gives a general recommendation for active people: 1.2 to 1.7 grams of protein per kilogram of body weight — or 0.5 to 0.8 grams per pound. (14)

If you’re trying to gain muscle or lose body fat, you may need more than that. 

For Muscle Growth

Multiple studies have tried to nail down the perfect protein intake goal for building muscle. First, be sure that you are resistance training and eating enough calories. 

The ACSM and the International Society of Sports Nutrition (ISSN) give slightly different recommendations. 

• ACSM Guidelines: 1.6 grams of protein per kilogram of body weight is the minimum for building muscle, and anything over 2.2 grams may be unnecessary. (14)
• ISSN Guidelines: 1.4 to 2.0 grams of protein per kilogram of body weight for building and maintaining muscle mass. (15)

Competitive bodybuilders looking to pack on as much muscle mass as possible while doing a high volume of training may need even more. Research shows most bodybuilders can achieve their gains at 2.3 to 3.1 grams of protein per kilogram of body weight per day. (16)

• Putting it all together, someone looking to build muscle mass who isn’t competing should aim for 1.4 to 2.2 grams of protein per kilogram of body weight per day.

For Fat Loss

When trying to lose body fat, you want to keep your protein high while reducing your calories or portions to help your body preserve lean muscle. Resistance training is also key to the equation.

• To lose body fat while maintaining muscle, the ISSN recommends 2.3 to 3.1 grams of protein per kilogram of body weight per day. (15)

Veg Out

If you don’t want to eat animal products, you can still crush your goals through high-protein vegetables. Getting enough protein helps you build muscle, lose body fat, and improve your heart, bone, and immune health. Even if you still eat meat, incorporating plant-based protein into your diet can further boost your heart health. 

That doesn’t mean you have to eat pounds of spinach after the gym to build your biceps. Choose from our list of the most protein-rich veggies and combine them into meals to reach your protein intake goals. Legumes, beans, peas, quinoa, wild rice, sweet corn, spinach, artichokes, collard greens, Brussels sprouts, and sweet potato all contain plant-based protein and other micronutrients to boost your health. Blend up a protein shake for even more.
