Whether you’re a weekend warrior or a competitive endurance athlete, the right fuel can help you push harder, recover faster, and enjoy better overall health. For vegan athletes, that fuel often comes from a plant-based diet that’s rich in whole grains, legumes, fruits, vegetables, and nuts.
The Vegan Advantage
Many plant-based foods are packed with vitamins, minerals, and antioxidants that can help reduce inflammation, improve cardiovascular health, and enhance recovery. Plus, a plant-based diet can provide all the protein, carbohydrates, and healthy fats you need to fuel your best performance.
Of course, there are some common myths about vegan diets for athletes that need to be debunked. Let’s dive into the science behind plant-powered endurance and explore the best ways to fuel your body for peak performance.
Improved Recovery and Reduced Inflammation
Eating a plant-based diet can help reduce inflammation in the body, which is important for athletes because chronic inflammation can slow down recovery and lead to injury. Plant-based foods like fruits, vegetables, whole grains, legumes, nuts, seeds, and herbs are rich in antioxidants, vitamins C and E, and other anti-inflammatory compounds that can help combat inflammation.
Research also shows that a plant-based diet can improve recovery by reducing muscle damage and oxidative stress. For example, one study published in the Journal of the International Society of Sports Nutrition found that plant-based protein sources like soy, pea, rice, and hemp were just as effective as animal protein in reducing muscle damage and improving recovery after resistance training.
Another study published in the same journal found that a plant-based diet rich in fruits, vegetables, whole grains, and legumes was associated with faster recovery of muscle function after high-intensity exercise.
Enhanced Cardiovascular Health
Plant-based diets are also linked to improved cardiovascular health, which is important for endurance athletes. According to the American Heart Association, a plant-based diet rich in fruits, vegetables, whole grains, legumes, nuts, seeds, and plant-based oils can help lower blood pressure, reduce inflammation, improve cholesterol levels, and reduce the risk of heart disease and stroke.
A study published in the Journal of the American College of Cardiology found that a plant-based diet was associated with a lower risk of cardiovascular disease and all-cause mortality compared to a diet that included meat.
Increased Energy and Stamina
Eating a variety of nutrient-dense plant-based foods can help provide the energy and stamina needed for long workouts and races. Complex carbs like whole grains and legumes are a great source of energy, while healthy fats like those found in nuts, seeds, avocados, and plant-based oils can help sustain energy and improve endurance.
The Vegan Myths and Misconceptions
Despite the evidence showing the benefits of a plant-based diet for athletes, there are still some common myths that need to be debunked.
The Protein Myth
One of the most common myths about vegan diets for athletes is that they’re lacking in protein. However, there are plenty of plant-based foods that are rich in protein, including:
- Legumes (lentils, chickpeas, black beans, soybeans)
- Nuts and seeds (almonds, cashews, peanuts, pumpkin seeds, sunflower seeds)
- Whole grains (quinoa, farro, bulgur, brown rice)
- Leafy greens (spinach, kale, collard greens)
- Protein-rich veggies (broccoli, Brussels sprouts, asparagus)
To get enough protein on a vegan diet, aim for about 0.8 grams per pound of body weight per day. That means a 150-pound person would need about 120 grams of protein per day.
It’s also important to note that the quality of protein matters. Plant-based protein sources like beans, nuts, seeds, and whole grains are complete proteins, meaning they contain all nine essential amino acids the body needs. Animal products, on the other hand, are complete proteins but are linked to health risks like heart disease and cancer.
Ensuring Adequate Nutrient Intake
Another myth about vegan diets for athletes is that they’re lacking in certain nutrients. However, with careful planning, a vegan diet can provide all the nutrients an athlete needs.
Here are some vegan-friendly sources of key nutrients:
- Calcium: leafy greens, fortified plant-based milks, tofu, sesame seeds, almonds
- Iron: leafy greens, lentils, chickpeas, pumpkin seeds, quinoa, fortified cereals
- Vitamin D: fortified plant-based milks, mushrooms exposed to sunlight, some orange juice
- Vitamin B12: fortified plant-based milks, cereals, nutritional yeast, some plant-based meat alternatives
It’s also important for vegan athletes to pay attention to their iodine intake. Iodine is important for thyroid health and is found mainly in seafood and dairy products. However, many plant-based milks and cereals are fortified with iodine, and sea vegetables like kelp and wakame are also good sources. A vegan multivitamin can also help ensure adequate iodine intake.
Finally, it’s important for vegan athletes to eat a variety of plant-based foods to ensure they’re getting all the nutrients they need. This can help prevent deficiencies and ensure optimal performance.
Fueling for Endurance
When it comes to fueling for endurance, there are a few key macronutrients to focus on: carbohydrates, protein, and healthy fats.
Carbohydrates: The Endurance Fuel
Carbohydrates are the body’s primary source of fuel for exercise. During long, intense workouts and races, the body relies on stored carbohydrates in the muscles and liver, which is why it’s important for endurance athletes to consume enough carbs in their diet.
Aim for about 6-10 grams of carbs per pound of body weight per day. That means a 150-pound person would need about 900-1500 grams of carbs per day, or about 3600-6000 calories (since one gram of carbs equals about four calories).
Most of your carbs should come from complex sources like whole grains, legumes, vegetables, and fruits. These foods are rich in fiber, which helps regulate blood sugar levels and keeps you feeling full and energized.
It’s also important to time your carb intake properly. Carb-loading before a long, intense workout or race can help provide extra energy and improve performance. This involves increasing your carb intake for several days before the event.
Protein: Building and Repairing Muscle
Protein is essential for building and repairing muscle, which is important for endurance athletes. While you don’t need as much protein as you might think, it’s important to get enough to support muscle growth and recovery.
As mentioned earlier, plant-based sources of protein like beans, nuts, seeds, and whole grains are complete proteins that provide all the essential amino acids the body needs. It’s important to eat a variety of these foods throughout the day to ensure you’re getting all the amino acids you need.
Most vegan athletes need about 0.8 grams of protein per pound of body weight per day. So, a 150-pound person would need about 120 grams of protein per day.
It’s also important to time your protein intake properly. Eating some protein within 30 minutes of finishing a workout or race can help speed up muscle recovery.
Fats: The Overlooked Endurance Fuel
Fats are an important source of energy for endurance athletes, but they’re often overlooked. While carbs get most of the attention when it comes to fueling for endurance, fats are just as important.
Your body can use fat as fuel during low-intensity exercise and when carb stores are running low. However, it takes longer for the body to convert fat into energy than it does for carbs, so it’s important to have a steady supply of fat in the diet.
Healthy sources of fat include avocados, nuts, seeds, olive oil, coconut oil, and plant-based milk alternatives like soy, almond, and oat milk.
Aim for about 0.5-1 gram of fat per pound of body weight per day. So, a 150-pound person would need about 75-150 grams of fat per day.
Micronutrient Essentials
In addition to macronutrients like carbs, protein, and healthy fats, there are also certain micronutrients that are important for endurance athletes.
Here are some key vitamins and minerals to focus on:
- Vitamin C: helps protect the body from oxidative stress and supports immune function
- Vitamin E: an antioxidant that helps protect cells from damage
- B vitamins: help convert food into energy and support nerve function
- Iron: important for oxygen transport and energy production
- Magnesium: helps with muscle function, nerve function, and energy production
- Calcium: important for muscle function, nerve function, and bone health
Many plant-based foods are rich in these micronutrients, but some athletes may benefit from a vegan multivitamin to ensure they’re getting enough.
One important note: while vitamin B12 is found mainly in animal products, there are some vegan sources of this important nutrient. Fortified plant-based milks, cereals, nutritional yeast, and some plant-based meat alternatives are good sources of vitamin B12.
Meal Planning and Nutrition Strategies
In addition to fueling your body with the right macros and micros, it’s also important to plan your meals and snacks strategically.
Optimizing Pre-Workout Nutrition
Eating a meal with carbs and some protein about three hours before a workout or race can help provide energy and support muscle recovery. Aim for about 3-4 grams of carbs per pound of body weight and about 0.3-0.5 grams of protein per pound of body weight.
If your workout or race is in the morning and you didn’t eat anything beforehand, aim for a meal or snack with about 1-2 grams of carbs per pound of body weight and some protein about an hour before you start exercising.
For example, a 150-pound person might aim for a meal with about 450-600 grams of carbs and 135-225 grams of protein three hours before a workout, and a snack with about 150-300 grams of carbs and 46-75 grams of protein about an hour before.
Fueling During Exercise
During long workouts and races, it’s important to keep your energy levels steady by consuming carbs throughout.
If you’re exercising for more than an hour, aim for about 30-60 grams of carbs per hour. You can get this from a combination of foods like:
- Dried fruit like dates, figs, or apricots
- Fresh fruit like bananas, apples, or oranges
- Portable snacks like energy balls or rice cakes with nut butter
- Homemade energy gels or bars (more on this later)
It’s also important to stay hydrated by sipping on water or a sports drink throughout your workout or race. Aim for about 16-20 ounces of fluid per hour.
Post-Workout Recovery
After a hard workout or race, your body needs to replenish its glycogen stores and repair damaged muscle tissue. Eating a meal or snack that contains carbs and protein within 30 minutes of finishing can help speed up this process.
Aim for about 1-2 grams of carbs per pound of body weight and about 0.15-0.3 grams of protein per pound of body weight. For example, a 150-pound person might aim for about 225-450 grams of carbs and 52-110 grams of protein.
Some good options include:
- A banana with almond butter
- A smoothie made with plant-based milk, frozen fruit, and a scoop of plant-based protein powder
- Quinoa or brown rice with beans, avocado, and salsa
- A vegetable stir-fry with tofu and brown rice
Training Adaptations for Vegan Athletes
While a well-planned vegan diet can provide all the nutrients an athlete needs, there are some training adaptations that vegan athletes may need to consider.
Periodization and Macrocycle Planning
Periodization refers to the process of structuring your training program over the course of a year, with different phases focused on different goals.
A typical macrocycle (or yearly training plan) includes a base phase, a build phase, a peak phase, and a taper phase. During the base phase, you focus on building a solid fitness base and increasing your training volume. During the build phase, you gradually increase the intensity of your workouts while maintain or slightly decreasing your volume. During the peak phase, you focus on high-intensity workouts and racing, and during the taper phase, you gradually decrease your training volume to allow your body to recover and be ready for your next race.
Vegan athletes may need to pay extra attention to their recovery during the build and peak phases, when they’re doing more intense workouts. This could involve things like getting more sleep, taking rest days, incorporating recovery activities like yoga or stretching, and making sure they’re getting enough protein and carbs in their diet.
Strength training is also important for endurance athletes, as it can help improve muscle function, reduce injury risk, and enhance performance. Vegan athletes can get all the protein they need from plant-based sources, so there’s no need to worry about getting enough protein for muscle growth and recovery.
Optimizing Hydration and Thermoregulation
Staying hydrated is important for all athletes, but it can be especially challenging for vegan athletes who may be avoiding sugary sports drinks or foods that contain animal products like gelatin.
One option is to make your own homemade sports drink using a base of coconut water, which is naturally high in electrolytes. You can add in some fruit for flavor and some vegan protein powder for extra aminos.
Another option is to use a plant-based electrolyte supplement. Look for one that contains sodium, potassium, magnesium, and calcium, as these are the main electrolytes you lose when you sweat.
When it comes to staying cool in hot weather, vegan athletes may want to consider using a plant-based sunscreen to protect their skin from the sun. Look for one that contains zinc oxide, which is a physical sunscreen that reflects UV rays instead of absorbing them like chemical sunscreens do.
Vegan Athlete Success Stories
There are many elite vegan athletes who have thrived on a plant-based diet, including:
- Fiona O’Neill, a professional marathoner who has set multiple Irish national records and competed in the Olympics
- Scott Jurek, an ultramarathoner who holds the course record for the famous Western States 100-mile race and has placed top 10 at the Hardrock 100 and Leadville 100 races
- Patrick Baboumian, a strongman competitor who set the world record for the log press at 502 pounds
- Brendan Brazier, an Ironman triathlete and author of several books on plant-powered nutrition for athletes
These athletes and many others have shown that it’s possible to fuel your body for peak performance on a plant-based diet.
Transitioning to a Vegan Diet
If you’re not already a vegan athlete and you’re thinking about making the switch, here are some tips to help make the transition smoother:
- Start by adding in more plant-based foods, rather than taking away animal products. This can help you get used to eating more veggies, fruits, whole grains, and legumes.
- Make sure you’re getting enough protein from plant-based sources like beans, lentils, chickpeas, quinoa, nuts, seeds, and whole grains. You may need to increase your serving sizes or eat more frequently at first to get used to the new amounts.
- Plan ahead for meals and snacks, especially for long workouts or races. You may need to bring your own food if you’re not sure there will be vegan options available.
- Be patient with yourself and don’t be too hard on yourself if you slip up or have a craving for something that’s not vegan. It’s normal and it’s okay to have occasional non-vegan foods.
With some planning, a little bit of experimentation, and a positive attitude, you can make the switch to a plant-based diet and fuel your body for your best performance yet.
