here is an indepth breakdown of who eats what:
Vegans don't eat any products of animal origin. This includes not only meat, but also dairy products (milk, butter, cheese), eggs and even honey. Many vegans do eat onion and garlic. The strictest vegans don't wear leather, wool or silk and also avoid health and beauty products made with ingredients derived from animals — for instance, lip balm with bees wax or skin creams with lanolin (an oil extracted from sheep's wool). Although some people who choose a vegan diet do so because they are allergic or insensitive to dairy products or eggs, most choose veganism because of ethical concerns. Most vegans have a deep commitment to ending the exploitation and mistreatment of animals. The term vegan, formed from first three and last two letters of the word veg etari an , was coined in London in 1944 by seven vegetarians who founded the Vegan Society.

Lacto-vegetarians/ Religion vegetarians / Lactose-Vegetarians are strict vegetarians who may consume milk and dairy products (optional) . Strictly No meat, no fishes, no eggs, no onion and no garlic. Lacto comes from the Latin word for milk.

Ovo-vegetarians are people who still eat eggs. Ovo from the Latin word for egg.

Lacto-ovo-vegetarians / Ovo-Lacto-vegetarians are those who eat both dairy products and eggs.

Macrobiotics A macrobiotic diet is mainly vegetarian, but macrobiotic diets often include seafood. In this diet all other meat products are excluded, as are eggs and dairy products. They also do not eat "nightshade vegetables" (potato, pepper and eggplant), refined sugar and tropical fruits. This diet contains many foods found in Asian countries such as miso soup, root vegetables (daikon and lotus) and sea vegetables (seaweed, kelp, arame). It emphasizes eating locally grown foods that are in season. Meals consist of 50% to 60% grains, 25% locally grown produce, and the rest of the diet mainly consists of beans and soups. In lesser amounts fruits, nuts and seeds are eaten. This diet is based on the Chinese principles of yin and yang. Some people follow this diet as a philosophy of life and others follow it for health reasons.

Flexitarian – a vegetarian who is flexible enough to occasionally eat meat or fish.

Demi-vegetarians don't eat red meat or poultry, but they do eat fish, eggs.

Pescetarians / Pesco-Vegetarians / Pesce-Vegetarians eat a vegetarian diet but also consume fish. Pescetarians may avoid red meat and poultry because they do not want to support factory farming or other inhumane methods of raising animals. For many people making the transition to vegetarianism, pescetarianism is a stage along the way to an entirely meatless diet.

Pollo-Vegetarians eat poultry, such as chicken, turkey, and duck.

Meat Restrictors avoid red meat, but may eat fish and poultry.

Pescaterians
Vegetarian still eats fish occasionally.

Vegetarian Sympathizers – Folks who do eat meat, fish, and chicken — but perhaps much less than they once did, and perhaps more carefully (they may choose organically raised meats). They lean somewhat towards a low- or no-meat way in their thinking. Frequently Sympathizers and Pesces are on the continuum towards a lacto- or vegan way of eating.
