Why Keep It Vegan Exists
According to Humane Research Council 84% of Vegetarians and Vegans return to meat. (Source [PDF])
That's an alarming statistic! If you're already abstaining from eating meat or all animal products, you might be wondering why this is. There are many reasons why someone might quit veganism/vegetarianism. Looking at the same study above, it appears the biggest reasons people quit a vegan/vegetarian diet is a lack of social support.
Looking at the "Key Difficulties with Vegetarian/Vegan Diets" table in HRC's study, over 70% of vegans/vegetarians say they aren't involved in any vegan/vegetarian groups or organizations. To add to that 41% of vegans and 63% of vegetarians say that they disliked that their vegan/vegetarian diet made them stick out from the crowd.
From this information, we can understand that pressure from friends and family can push you off course from following a vegan/vegetarian diet. The more social pressure, the farther away you drift from the initial reasons that made you want to go plant-based. You start to forget about the animals. You start to forget about the health benefits. You start to forget about the environmental devastation caused by animal agriculture.
