What do you call a person who follows a diet that prohibits the consumption of any animal byproducts?

A person who follows a diet that prohibits the consumption of any animal byproducts is referred to as a vegan. This dietary choice goes beyond just avoiding meat; it encompasses the exclusion of all animal-derived products, which includes dairy, eggs, and even honey. Vegans often make this choice for various reasons, including ethical concerns about animal welfare, environmental sustainability, and health benefits.

In contrast, a vegetarian does not consume meat but may include animal byproducts like dairy and eggs in their diet. A pescatarian includes fish and seafood in their diet along with plant-based foods, while a flexitarian primarily eats a plant-based diet but occasionally includes meat or fish. Each of these dietary choices has its own specific guidelines and ethics, but only veganism completely avoids all animal byproducts.
