5 Nutrition Tips for Vegan Athletes

Today I’m going to cover a few nutrition tips for vegan athletes. It doesn’t matter if your idea of exercise is a half an hour walk every night, 2 hours of weightlifting at the gym every day, or something in between: optimal nutrition is a key to optimal performance.


When it comes to nutrition and athletic performance, we’ve all heard so much information – often contradictory – that it’s hard not to get puzzled sometimes. And for those of us who has made a switch to a vegan diet while staying physically active, figuring out nutrition for optimal performance might seem like an even more difficult task.

As you may know, I’ve been training for a marathon for the past few weeks. You can see my week 6 marathon training update below, plus check out all of my other training updates and the eventual race recap over here.

Since my goal is to train for a marathon in a healthy way while eating a plant-based vegan diet, I’ve done a lot of research to make sure I was doing everything right.

Nobody’s perfect, of course, and I’ll admit that since starting my vegan marathon training journey, I’ve had weeks when I was bursting with energy while running/working out hard, and other weeks when I was just dragging by with a similar exercise load.

This loosely translates that my nutrition might not have been perfectly balanced at times, and a number of other factors (sleep, stress, etc.) were sucking energy out of me.basketoffruit

While it’s hard to control our sleep or stress levels, we can all put some effort into making our nutrition better. I admit that I’ve made some mistakes in my vegan diet, but after doing proper research I’ve put up a list of facts that can benefit us all no matter of our physical activity level. Here we go:

5 Basic Nutrition Tips for Vegan Athletes

1. You don’t need more protein – just more calories!

This is a fact that a lot of vegan fitness gurus emphasize.

Our bodies need plenty of energy to sustain a hard effort when exercising or training for a race. While protein is vital to us all, it’s not the lack of it in a vegan diet that makes us exhausted – it’s the lack of overall calories!

A common misconception about a vegan diet is that it implies eating nothing but salad and thus lacks in protein, but people often overlook the fact that plants, grains, and starchy vegetables supply a decent amount of it. As long as you consume a wide variety of plant-based foods, you’re good to go! Even when training for a marathon.

2. Eat carbohydrate-rich food in its natural state before and after exercise.

Even if your stomach is averse to food very early in the morning before an am workout, you’ve got to top off your glycogen (carbs stored in your muscles and liver for use during exercise). This will help you maintain a harder effort, last longer, and recover better after the workout!

I’m not a big fan of eating very early, but I’ve been working on it: half a banana or 3-4 dried dates with a cup of coffee 30-60 minutes before a run usually sit well in my stomach, but you can always experiment with other foods to find out what works for you.

However, try to avoid a lot of fiber pre-workout as fiber stays in your stomach longer, thus increasing your chances of gastrointestinal trouble when you least need it!

After the workout, you’ve got 30-60 min to have another breakfast: the carbs consumed at this time go directly to your muscles and liver to be stored as glycogen for your next exercise session. An ideal ratio of carbs to protein at this meal is considered to be 4 to 1. Oatmeal, cereal, pancakes, smoothies (like the Swamp Monster Smoothie from my blog!) all work well.

3. Don’t get too hung up on numbers in your diet!

Whether it’s about calories or protein/carbs/fat ratio, figuring out numbers can distract your attention from a bigger goal – eating a healthy diet full of a variety of whole food, plant-based components for optimal health and athletic performance.

T. Colin Campbell, professor emeritus of nutritional biochemistry at Cornell University, describes this number-picking (my phrasing) in his book Whole: Rethinking the Science of Nutrition as a ‘reductionist’ approach in science and all areas of life opposed to a more beneficial to us ‘wholistic’ approach.

Campbell and a number of other outstanding scientists and doctors propose the consumption of starchy vegetables and grains complemented with vegetables, beans, fruits, and berries close to their ‘whole’, natural state as a diet that’s most beneficial to human health. ( For more on this, see the work of John McDougall, Caldwell Esselstyn Jr., Neal Barnard, Joel Fuhrman and others.)

4. A variety of whole, plant-based foods benefits us as athletes!

There are numerous ways of how a whole food plant-based diet brings out the best in us:

A) Optimized recovery: antioxidants found in plants reduce oxidative effect of exercise on our bodies (less inflammation!) and help flush out lactic acid that makes our muscles sore.

Plants contain up to 64 times the amount of antioxidants than meat, fish, dairy, and eggs. Watercress, cherries, and citrus fruit have shown positive effect on post-exercise recovery in studies. (For more on this, check out the work of Michael Greger and his awesome website).

B) No need for supplements! Vitamins and micronutrients found in whole foods act much more efficiently inside our bodies than their pill forms. That includes not just synthetically derived vitamins, but also the ‘all-natural’ vitamin brands.

Possible explanation? The whole is more than the sum of its parts when it comes to plants: the combination of all components of plant-based foods (both known to us and not yet discovered) works much better together than separately. Plus, sometimes high doses of vitamins found in pills can be toxic for us!

The only exception is vitamin B12: most plant-based diet advocates agree on supplementation of this vitamin for vegans, plus it’s not toxic to us at higher doses.

C) Nothing to weigh us down! Consuming plants provides us with macro- and micronutrients, fiber, antioxidants, vitamins, minerals – and none of the artery-clogging cholesterol* or hard-to-digest animal protein.

Studies by Caldwell Esselstyn Jr. and other researchers have shown that eliminating all added oils from our diet can repair the endothelial cells that make up the inner lining of our arteries, thus not only preventing, but also reversing heart disease! Imagine how much your athletic performance is going to improve once you ditch all the junk out of your diet!

5. Reevaluate your sodium intake.

We’ve all heard that too much sodium in our diets can lead to a number of health problems, high blood pressure being one of them. Some of us might have even tried to reduce the amount of salt they add to home-cooked food.

However, if you participate in endurance sports that last for hours (running, cycling, triathlons, etc.), you might be losing too much sodium through sweat.

We need to maintain a certain level of sodium in our blood and tissues, so if you are a heavy sweater, you might want to consider adding a sports drink with some sodium and potassium during long bouts of exercise (more than an hour), and eating something salty after your workout.

You might have even heard about or experienced a condition called hyponatremia during long runs: dangerously low levels of sodium in the body paired with drinking sodium-free water cause swelling of brain and tissues, which results in disorientation, drastic decrease in performance, and sometimes fainting. As you see, too little sodium can be just as painful as too much.

While this list of tips on nutrition for newly vegan athletes can be expanded, it covers basics that all athletes (including more experienced vegan athletes) can benefit from. I recommend that we all ( myself too!) come back to this list every now and then to gauge our athletic progress, and especially if our performance stalls or if we start feeling sluggish. Also check out my list of 10 vegan pantry staples that can take your health and performance to the next level.

Now I’d like to share my marathon training update.

Week 6 of Marathon Training Update

Week 6 went by very quickly, especially with all the prep for the Labor Day weekend! I was glad that all of the holiday activities didn’t derail my training, and I managed to complete all of the planned workouts.

My long run on Sunday was 14 miles, and I completed it with a 9:04 min/mile average pace. It was nice that I met up with some friends in the middle of that run, and we did about five miles together – a nice break from “the loneliness of a long-distance runner”.

Besides that, I had a great track workout on Wednesday with the same couple of runners I mentioned before. We did a so-called ‘ladder’: run hard for 200-400-600-800 meters with 400 meters of recovery in between each effort, and then do the entire thing backwards, i.e. 800-600-400-200 with a lap in between. My running partners are faster than me, but I was still glad that I could maintain a decent effort the whole time.

Now that I’m going into week 7 of marathon training, I’m still trying to figure out how to have six days a week of working out with only one day of recovery. So far it seems like a too lofty goal at least for two reasons:

– I tend to get too tired if I follow the 6:1 ratio;

– Life always finds ways to interfere, and I’m not a fan of feeling guilty if I wasn’t able to achieve a set goal.

This being said, I also realize that I’m not a superhuman! Plus, sometimes lower level of exercising turns out to be a better way for us to achieve goals because our bodies don’t get beat up as bad!

When I was training for Pensacola Marathon last year, I had 4-5 workouts a week instead of 6, only had one looong run of 19 miles (while most plans advice two 20-milers), and still finished well ahead of the time I was expecting from myself (4 hours and 4 minutes instead of anticipated 4:20-4:30).

Anyway, hope you enjoyed today’s post!

You might skip the morning coffee unless it is decaf. Esselstyn says it impairs the endothelial lining of the arteries. You may want to have some dark greens and a little balsamic vinegar which increases the N.O. in the bloodstream before working out.

I only do half-marathons, at almost 51 though I'm happy to be out there and still training even though I do have back pain issues. I have a race coming up and your article will help ;)

The article is a good article, however, I disagree with the recommendations for supplements--it's simply wrong, ESP. in light of your lower-back troubles. Vitamin C (ascorbic acid) is super beneficial for alleviating lower back pain and would be an awesome addition to your healthy diet. I'm tired of blanket statements of "no need to take dietary supplements" that are simply not true. If you want to train hard, supplements might prove beneficial. Some can do well without them, I just prefer them as my running, training and recovery is simply better with them. - Tom, (Won age group (55-59) award--1st--in a 5 km race the other day.)

Good luck with your upcoming race, Trish! Hope your back issues resolve themselves.
