I think it's certainly proven WHY there aren't any vegan hiking clubs though.
How so, jdeks?
Sorry, if you can't see it by now, I don't think I can explain it.

Think before you type.
Righto, threadjack due multilevel misinformation:
Vegan and vegetarians, statistically speaking, typically have lower iron stores. No, I dont want to start a debate about how "But
I'm a vegan and
I'm perfectly healthy" - I'm sure you are, and while it's certainly possible to have a vegan/vego diet that meets your (also typically lower) iron intake requirements, the fact is that many a study has shown healthy, non-anemic vegans and vegoes still have lower serum ferritin readings.
This isn't an issue for 99% of people. But if you start rapid exposure to higher altitudes, those iron stores act are your buffer, and if they're already low it reduces you ability to start pumping out haemoglobin to deal with lower 02 levels. Combine this with a diet typically also low in vit B12 (only found in meat and dairy, critical for red blood cell production), THIS is when anemia CAN become a thing.
Does this cause altitude sickness? Not really. Definitely not ideal though.
Reduced 02 absorbtion means your heart and lungs work overtime to meet respiration needs, and you burn calories like CRAZY, on top of some fairly major exertion already. Vegans can get calories in, sure - but the volume of food you need to carry and prepare is much greater, and considering even omnivorous mountaineers have to make an effort to get joules in, there's a real risk of entering caloric deficiency aka starvation.
Does this cause altitude sickness? Quite possibly. Sure doesn't help. More likely leads to exhaustion that masks the early warning signs that you need to GO DOWN RIGHT NOW.
3 days before Maria died, Kuntal Joisher actually became the first vegan to climb everest. The difference was that he'd been climbing in Nepal for years, and 2 years prior had summited Manaslu (26,700ft). He'd spent the 2014 and 2015 season on Everest too. He was an experienced mountaineer, with maintained altitude conditioning. On the other hand, Maria and her husband (who also got medivac'd with hape), had only sporadic trekking ascents of mountains like Kili and Denali, spread out over 8 years. The highest they'd been was Aconcagua - a 22,000ft hike with no technical climbing or time at Everest-tier altitudes. But they'd set their symbolic '7 peaks' goal, and to prove their point about veganism they persisted in climbing a mountain several leagues above anything they'd experienced - physically, technically and environmentally.
Now, does this cause altitude sickness? Yes. More than anything else, by a big margin.
Lack of steaks isn't what killed her. Pushing herself on a mountain she was not conditioned to climb, so she could tell everyone she was a vegan, was.
