The 4 Types of Vegetarians
Lacto-Ovo, Ovo, Vegan, and Vegetarian
An lacto-ovo vegetarian is a vegetarian who does not eat animal flesh of any kind, but consumes dairy and egg products.
Ovo vegetarianism is a type of vegetarianism which allows for the consumption of eggs; unlike lacto vegetarians, no dairy products are permitted. Those who practice ovo vegetarianism are called ovo-vegetarians or "eggetarians."
Veganism is the practice of abstaining from the use of all animal products.
A vegetarian is a person who does not eat meat, and sometimes other animal products.
