A vegan diet can improve athletic performance

A dairy-free, plant-based diet provides all the energy and nutrients you need to up your game in training and competition.

A diet rich in carbohydrates increases both endurance and intermittent high-intensity performance because of the extra store of carbohydrates in the muscles and liver, called glycogen. 

For athletes, a high-carb diet sustains the daily demands of training and exercise. And while the needs will vary based on the individual and their sports, carbs should always be their main source of calories. 

Carbohydrates are critical for maximum energy, speed, stamina, concentration, recovery, and better fluid balance. 

Pro tip: The main sources of carbs are all plant foods: cereal grains, vegetables, and fruit.


Athletes need protein to build and repair tissue in the body. Protein promotes muscle mass, improves metabolism, and speeds up recovery after exercise.

Are plant-based proteins complete proteins?

There are 9 essential amino acids that your body cannot produce on its own. While not all plants are considered complete proteins, a varied diet can provide everything your body needs. The only way to not consume the complete spectrum of amino acids is by eating a very limited diet comprising just a handful of foods. The benefit of obtaining protein through plants is variety—and a varied diet, rich in whole foods, is the gold standard for human health and longevity. Of course, many plants are considered complete proteins by themselves:

Complete protein plant foods:

  • Quinoa
  • Soy
  • Hemp
  • Chia seeds
  • Buckwheat
  • Spirulina
  • Tempeh

High-protein plant foods:

  • Tempeh (20 grams/cup)
  • Lentils (18 grams/cup)
  • Edamame (19 grams/cup)
  • Hemp seeds (10 grams/ 3 tbsp)
  • Tofu (26 grams/ 3/4 cup)
  • Soy Milk (8 grams/cup)
  • Pea milk (8 grams/cup)
  • Quinoa (8 grams/cup)
  • Black Beans (15 grams/cup)
  • Peanut Butter (7 grams/2 tbsp)

Athlete testimonials

Olympic and elite athletes share their reasons for going dairy-free.

After I went vegan, I started repairing and recovering much faster. I could handle more load, out on the track and in the weight room. It made us a better team.

Dotsie Bausch, Olympic Medalist

Athletes should not drink cow’s milk. Dairy is not a health food. When I ditched dairy, I felt an almost immediate resurgence in energy and vitality that I was not expecting.

Rich Roll, Vegan Ultraman World Champion

After I went plant-based, I lost 4% body fat, I was stronger, and I was recovering faster. My body just became much more efficient.

Derrick Morgan, Tennessee Titans Linebacker

When I cut out dairy from my diet, my allergies and stomachaches completely went away. Telling kids cow’s milk is healthy is dangerous.

Rebeca Soni, Multiple Olympic Medalist
