Somewhere in a gym right now, someone is telling a vegan lifter they’ll never build real muscle without meat. It’s one of the most persistent myths in fitness culture — the idea that plants can fuel a decent salad, but not a deadlift, a marathon, or a title fight.
The problem is that the evidence walking around in professional locker rooms says otherwise. Strongmen, Grand Slam finalists, Ironman champions and UFC veterans have all built their careers while eating entirely plant-based. Not as a gimmick, not for a single season, but as a sustained part of how they train and recover at the highest level.
This isn’t a list of casual claims. Every athlete below has spoken publicly, repeatedly, and on record about being vegan while competing. Here are 13 of them, and what their careers actually show about plant-based performance.
Key Takeaways
- Vegan athletes compete at the highest levels of strength sports, endurance racing, tennis, MMA and team sports, not just niche fitness circles.
- Several of the athletes on this list, including Patrik Baboumian and Kendrick Farris, set national or world records for strength or lifting totals while eating fully plant-based.
- Endurance is one of the categories with the strongest track record, with ultramarathoners and Ironman finishers like Rich Roll and Fiona Oakes going vegan for the bulk of their competitive careers.
- Protein and recovery are manageable on a vegan diet with planning, and many of these athletes work with sports nutritionists to hit specific targets.
- The common myth that plant-based eating caps athletic ceiling doesn’t hold up against these documented, verifiable careers.
Strength and Power Athletes
If plants really couldn’t build muscle, this category shouldn’t exist. These athletes made their names lifting heavy things, and they did it on a vegan diet.
1. Patrik Baboumian
Patrik Baboumian is arguably the single most cited counterexample to the ‘no protein, no muscle’ myth. The German strongman, who once held the title of Germany’s Strongest Man, went vegan in 2011 and continued competing at an elite level afterward, setting a log lift world record in the process.
He’s since become an outspoken advocate, showing up at strongman events lifting stones and logs that would flatten most skeptics, all while eating a plant-based diet.
2. Kendrick Farris
Kendrick Farris represented the United States in weightlifting at three Olympic Games — 2008, 2012 and 2016 — and transitioned to a fully plant-based diet partway through his competitive career.
He’s spoken openly about maintaining his snatch and clean-and-jerk totals after the switch, using his platform to challenge assumptions about vegan diets and Olympic-level strength sports.
3. Jehina Malik
Jehina Malik is a competitive bodybuilder who built a visibly muscular physique on a plant-based diet, competing in bikini and figure divisions.
She’s talked in interviews about structuring meals around legumes, tofu, seitan and grains to hit the protein numbers bodybuilding judges expect to see on stage, directly rebutting the idea that visible muscle requires animal protein.
Endurance Athletes
Endurance sport is where the plant-based track record runs deepest, with multiple record holders and repeat champions who’ve raced for years, not just one breakout season.
4. Rich Roll
Rich Roll is one of the best-known vegan endurance athletes in the world, largely because he transformed from an overweight, unhealthy 40-year-old into someone who completed five Ironman-distance triathlons in five days across five islands — the EPIC5 Challenge.
He adopted a plant-based diet as part of that turnaround and has documented his ongoing training and racing extensively on his own podcast and in his memoir Finding Ultra.
5. Fiona Oakes
Fiona Oakes is a British marathon runner and firefighter who has won marathons on multiple continents, including setting course records, all while running vegan since childhood.
She’s completed marathons in Antarctica and the North Pole, environments that leave zero room for underfueling, and has been vegan for over four decades.
6. Scott Jurek
Scott Jurek is a two-time Western States 100 champion (with seven consecutive wins) and one of the most decorated ultramarathoners in American history.
He adopted a plant-based diet years into his competitive career and continued winning some of the toughest 100-mile trail races in the sport, later co-authoring the bestselling book Eat and Run about his approach to plant-based ultrarunning.
7. Timothy Bradley Jr.
Timothy Bradley Jr. is a former unified world boxing champion across multiple weight classes who switched to a vegan diet during his active competitive career, not after retirement.
He’s credited the change with helping his recovery between fights and continued fighting at world-title level after making the switch.
Team Sport and Combat Sport Athletes
Team and combat sports demand explosive power, quick recovery between contests, and consistency across a long season — exactly the areas skeptics assume plant-based diets can’t support.
8. Derrick Morgan
Derrick Morgan spent nearly a decade as a defensive end in the NFL, mostly with the Tennessee Titans, and switched to a plant-based diet partway through his career after researching inflammation and recovery.
He continued playing at a professional level in one of the most physically punishing sports in the world after making the change.
9. David Haye
David Haye is a former unified world heavyweight boxing champion who has spoken about periods of plant-based eating during training camps, citing recovery and inflammation benefits.
As a heavyweight boxer, his career sits directly against the assumption that big, powerful frames need animal protein to function at the top of a weight class.
10. Nate Diaz
Nate Diaz is a UFC veteran known for his gas tank — his ability to keep working at a high pace deep into fights — and has discussed following plant-based and vegan-leaning nutrition during parts of his career.
In a sport where three five-minute rounds can end in exhaustion, his documented endurance is notable.
Racket and Precision Sport Athletes
Not every sport demands raw power. Some demand split-second reaction time, sustained focus over hours-long matches, and precise motor control — and vegan athletes have excelled here too.
11. Venus Williams
Venus Williams, seven-time Grand Slam singles champion, adopted a raw vegan diet after being diagnosed with Sjögren’s syndrome, an autoimmune condition, and has spoken about how the change helped her manage symptoms and return to competing at the top level of professional tennis, including reaching a Wimbledon final years after her diagnosis.
12. Lewis Hamilton
Lewis Hamilton, seven-time Formula 1 World Champion, went fully vegan in 2017, citing both animal welfare and health reasons, and continued winning championships afterward.
F1 driving demands intense core strength, neck strength to withstand G-forces, and sustained concentration over race distances, all of which he maintained post-transition.
13. Meagan Duhamel
Meagan Duhamel is a Canadian figure skater who won Olympic gold and world championship titles in pairs skating while following a vegan diet, which she adopted for both ethical and performance reasons.
Figure skating demands explosive jumping power combined with precise body control, and she’s credited her diet with helping her strength-to-weight ratio in a sport where every extra ounce matters on landing.
Frequently Asked Questions
Is it actually possible to get enough protein as a vegan athlete?
Yes, though it takes some planning. Athletes on this list typically combine legumes, tofu, tempeh, seitan, quinoa and protein-rich plant powders to hit the higher protein targets that intense training demands. For a deeper breakdown of options, see our guide to high-protein foods for vegans.
Do any major sports organizations support vegan diets for athletes?
Individual team nutritionists and sports dietitians increasingly work with athletes on fully plant-based meal plans, and organizations like the Academy of Nutrition and Dietetics have stated that well-planned vegetarian and vegan diets can meet the nutritional needs of athletes at all levels, including endurance and strength sports.
Did any of these athletes switch to vegan mid-career, or were they always plant-based?
Both patterns show up on this list. Fiona Oakes has been vegan since childhood, while athletes like Lewis Hamilton, Derrick Morgan and Timothy Bradley Jr. switched partway through already-established professional careers and kept competing at the same or higher level afterward.
Is there scientific research on vegan diets and athletic performance?
Yes. A 2021 review published in Nutrients examined plant-based diets in athletes and found no consistent disadvantage in strength or endurance outcomes when protein and calorie needs were adequately met, though individual nutrient planning (like B12, iron and creatine) remains important.
What’s the difference between these athletes and someone who just eats a lot of salads?
The athletes profiled here follow structured, calorie- and protein-adequate plant-based diets designed around their specific training loads, often with professional dietitian support, which is very different from an unplanned diet low in overall calories or protein.
