Most people choose it because they think it helps animals from being slaughtered. (it really doesn't, but that's beside the point.) Some choose it because it helps you lose weight. There are multiple reasons but I think those are the main ones.
There are many reasons why people become vegetarians. Some people do it for health and others do it to support animal rights.
Are you asking why people change from being non-vegetarians to lacto-ove-vegetarians? Probably because they care about animal cruelty and want to reduce it. May be they are in their path to become Vegans too. Some of them do it for health reasons too, seeing that vegetarian diet is more beneficial.
Some are, but many are not.
Vegetarians do not eat caviar because it is derived from fish eggs, which is an animal product. Some reasons why vegetarians may choose not to consume caviar include ethical concerns about harming animals, environmental sustainability issues related to overfishing, and personal health reasons due to high levels of mercury and other contaminants found in caviar.
Some vegetarians see it from the bible about how Jesus served fish and bread that it is okay to eat fish, it's not. People who eat fish are not vegetarians. Many people equate the word 'animal' with 'mammal'.
Yes, Some people do hate chicken. Example: Some Vegetarians and Vegans
just had a read around and found that the situation is the same as anywhere else some people don't eat it for religious reasons. some are vegetarians, and some that dont eat it for religious reasons still sneak a bit once in a while. Yes Bacon is available In Kenya for normal domestic consumption.
Lack of belief in self and misplaced priorities are some of the reasons that hinder some people from become the best that they can.
Some people are vegetarian for health reasons not because of the animal cruelty. If they're vegetarian because of animal cruelty, they're arrogant and rather ignorant, in my opinion.
maybe because they are trying to go on a diet
There are many reasons one may choose to become a doctor. Some people are lured by the salary, and others simply enjoy helping people.
People's bodies are different in general regardless of their diet. Some vegetarians are thinner than most, but for the most part, each person's body type is unique to them and not particularly their diet.
