Veganism is both the practice of abstaining from the use of animal products, particularly in diet, and an associated philosophy that rejects the commodity status of animals. A follower of either the diet or the philosophy is known as a vegan (pronounced VEE-gən). Distinctions are sometimes made between several categories of veganism.

But vegetarian diets vary in what foods they include and exclude: Lacto-vegetarian diets exclude meat, fish, poultry and eggs, as well as foods that contain them.

In other words, a vegetarian is someone who doesn't eat any kind of meat. A vegetarian doesn't eat chicken, hamburgers, steak, fish, shrimp, lobster or any animals or seafood. Lacto-vegetarian is sometimes used to describe a vegetarian who does not eat eggs, but does eat dairy products. Many Hindu vegetarians are lacto-vegetarians who avoid eggs for religious reasons while continuing to eat dairy. Ovo-vegetarian refers to people who do not eat meat or dairy products but do eat eggs.

Veganism has come a long way: once reserved for peace-loving hippies, interest in a totally animal-free diet is at an all-time high, with celebrities like Bill Clinton, Alicia Silverstone, Jay Z, and Beyoncé leading the charge. But before you jump on the no-meat-eggs-or-dairy bandwagon, you should know what you're getting into.

When most people think of vegetarians, they think of lacto-ovo-vegetarians: People who do not eat beef, pork, poultry, fish, shellfish, insects or animal flesh of any kind, but do eat eggs and dairy products are lacto-ovo vegetarians (“lacto” comes from the Latin for milk, and “ovo” for egg).

Vegan vs. Vegetarian. Neither vegans nor vegetarians eat meat. However, while vegetarians tend to consume dairy products and eggs, a vegan avoids all animal products, including eggs and dairy, and often inedible animal-based products, such as leather, wool, and silk. Vegetarianism is usually a diet, while veganism is a lifestyle.
