Why Some People Quit Veganism After Years

Ex vegan stories have become a genuine subgenre online, often framed as proof that veganism inevitably fails. The most frequently cited statistic behind that narrative, that 84 percent of vegans quit, is more complicated than it first appears.

That number comes from a decade old survey that mostly captured people testing out a plant based diet for a few months, not long term committed vegans. The reasons people who actually stick with veganism for years eventually walk away look considerably different.

None of it means veganism is destined to fail for everyone who tries it. Here is why some people genuinely quit after years, once the honest reasons get separated from the misleading headline statistic.

The Famous 84 Percent Statistic Is Widely Misunderstood

The 84 percent figure traces back to a Faunalytics survey of more than 11,000 American adults, and more than a third of those counted had quit within just the first three months. Many of them, according to Vegan Food & Living, may never have fully committed to veganism as an identity in the first place, making the number a poor measure of long term failure.

Vegan alternatives themselves often take the blame too, frequently criticized as overly processed. “Research currently suggests that vegan alternatives, even when ultra processed, are on average healthier” than ultra processed foods containing animal products, nutritionist Stedman explained to the same outlet.

Long Term Quitters Cite Different Reasons Entirely

Among people who do eventually quit, food dissatisfaction and health concerns like fatigue and weakness rank as the two most common reasons, according to Daily Vegan Meal. Both often trace back to the same root issue, plant foods are generally far less calorie dense than animal products, and people frequently end up in an unintentional calorie deficit.

Nutrient deficiencies compound the problem for some longtime vegans specifically, with roughly one in five reporting a vitamin B12 deficiency, according to Nourish You. B12 plays a critical role in nerve and blood cell function, and it comes almost exclusively from animal products or fortified foods rather than typical whole plant foods.

Social Isolation Plays A Bigger Role Than People Admit

Roughly 63 percent of people who abandon a vegan or vegetarian diet report feeling like they stood out too much socially, according to the same Nourish You report. Navigating family meals, travel and long standing relationships while maintaining a genuinely different diet can wear on people over years, even when the original motivation never actually changes.

One former vegan wrote publicly about noticing a broader pattern of people falling back to eating animal products somewhere between three and five years into the lifestyle, according to a personal account published on Substack. She specifically pushed back against the idea that people who leave were never really committed in the first place.

The people who quit veganism after genuinely years of commitment rarely do so lightly, and the reasons tend to be about health, nutrition and the social weight of staying different for that long. None of that erases the ethical motivation that got them there in the first place, it just means the diet, as practiced, stopped working for their specific body or life.
