A lacto-vegetarian diet is a diet that abstains from the consumption of meat as well as eggs, while still consuming dairy products such as milk, cheese, yogurt, butter, ghee, cream, and kefir.
A flexitarian diet, also called a semi-vegetarian diet, is one that is centered on plant foods with limited or occasional inclusion of meat. For example, a flexitarian might eat meat only some days each week. Flexitarian is a portmanteau of the words flexible and vegetarian, signifying its followers' less strict diet pattern when compared to vegetarian pattern diets.
In nutrition, diet is the sum of food consumed by a person or other organism. The word diet often implies the use of specific intake of nutrition for health or weight-management reasons. Although humans are omnivores, each culture and each person holds some food preferences or some food taboos. This may be due to personal tastes or ethical reasons. Individual dietary choices may be more or less healthy.
A plant-based diet is a diet consisting mostly or entirely of plant-based foods. Plant-based diets encompass a wide range of dietary patterns that contain low amounts of animal products and high amounts of fiber-rich plant products such as vegetables, fruits, whole grains, legumes, nuts and seeds. They do not need to be vegan or vegetarian, but are defined in terms of low frequency of animal food consumption.

It is practised by Jain ascetics and lay Jains.

Non-vegetarian food contains meat, and sometimes, eggs. The term is common in India, but not usual elsewhere. In the generally vegetarian environment of India, restaurants offering meat and fish usually have a "non-vegetarian" section of their menu, and may include the term in their name-boards and advertising. When describing people, non-vegetarians eat meat and/or eggs, as opposed to vegetarians. But in India, consumption of dairy foods is usual for both groups.
