There are a few types of vegetarian eating plans such as:
Lacto vegetarian: all plant foods, plus dairy products
Ovo-vegetarian: all plant foods, plus eggs
Lacto-ovo vegetarian: all plant foods, plus dairy and eggs
Plant-based: this is not vegetarian but a mostly plant-based diet. It could still include all types of meat and animal products but in smaller portions, less often.
Any of these plans can be followed indefinitely or could be a stepping stone to a vegan eating plan.
