T. Colin Campbell Center for Nutrition Studies

Building your muscles on a plant-based diet is possible, and despite what you might have heard, it does not require extra effort compared to muscle-building on a meat-based diet. It may even be easier on a plant-based diet because you will likely deal with less inflammation, and your recovery time may be shorter.

But that does not mean it is easy. The essential components of muscle building are consistent regardless of your diet, and no matter what you eat, it takes work. So, where do you begin? Let’s quickly look at three common pitfalls or misunderstandings about muscle building.

Protein Intake

The first misconception is that protein is the king of kings and that it’s nearly impossible to get enough protein for muscle building on a plant-based diet. Like many misconceptions, this one has a kernel of truth: the truth is that protein is critical. After all, it is an essential nutrient. Protein is especially important if you want to increase muscle mass because it makes up much of the structural components of our tissues.

However, you can get enough on a plant-based diet.

In most industrial countries, protein deficiency is rare, even when consuming a vegetarian or vegan diet. This is because protein is found in varying amounts in all foods except for highly processed food fragments like oils. While the protein levels in foods vary, as long as you consume enough calories from a wide range of whole plants, you will get an adequate amount to meet your body’s demands.

The next time someone at the gym asks where you get your protein from, feel free to share this list of plant-based protein powerhouses:

  • Tofu: 21.8 grams of protein per ½ cup
  • Tempeh: 15.0 grams of protein per 3-ounce serving
  • Lentils: 9.0 grams of protein per ½ cup
  • Oats: 10.7 grams in 1 cup
  • Chickpeas: 6.3 grams protein per ½ cup
  • Black rice: 8.0 grams of protein per ½ cup
  • Almonds: 7.0 grams of protein per ¼ cup
  • Quinoa: 8.0 grams of protein per cup
  • Hemp seeds: 10.0 grams of protein per serving (3 tablespoons)

To give you some context for these numbers, “the recommended dietary allowance (RDA) for adults is 0.8 grams per kilogram of body weight. This recommendation is calculated by adding two standard deviations to the estimated average requirement (EAR), which is the level of intake estimated to meet the needs of at least half of all healthy individuals.” By adding two standard deviations, the RDA meets or exceeds the needs of 97.5 percent of individuals. According to the RDA, a healthy male weighing 70 kilograms (144 pounds) should consume 56 grams of protein daily (70 x 0.8 = 56); a healthy female weighing 60 kilograms should consume 48 grams of protein daily. This amount, which represents about 10 percent of total calories from protein, has been empirically established for many decades.

Strength Training

Another common error when trying to develop your muscles is never establishing a consistent strength training routine. You can indeed improve your overall fitness by doing cardio workouts—jogging, swimming, biking, etc.—and each of those activities will gradually improve your strength in certain muscle groups, but to increase overall muscle mass throughout the body, you must perform strength training exercises.

When we overload muscles with resistive exercises such as weightlifting, microtears form in the muscle fibers. These microtears signal to the body to send nutrition and blood flow to the muscle tissue for repair. Repeatedly microtearing and rebuilding muscle tissue results in hypertrophy—an increase in muscle mass.

You should return to your strength training exercises regularly, especially in the beginning when you are establishing a routine. For optimal muscle growth, aim for three to five strength training sessions per week.

Rest and recovery

Lastly, you must not neglect rest and recovery! In their enthusiasm to get stronger, many people push their bodies non-stop. This is not a recipe for success. In fact, rest days are crucial for muscle building. Resting allows your body to overcome and adapt to the stress of strength training.

Rest days can be either passive or active. Passive recovery days involve taking the entire day off from exercise, whereas active recovery days include light activities like stretching, walking, or gentle yoga. Most rest days should include some active recovery, and you should aim for one to three rest days per week, depending on the intensity of your workouts.

Make no mistake—you can transform your body on a plant-based diet. As with all exercise, there may be challenging times, particularly when you start. But ultimately, if you take heed of the three components above, you will be well on your way!
