I'm vegetarian because I like the food, but also because of health issues. I was on Permarin for years and it's messed up my liver and kidneys a bit. Nothing like being rushed off to hospital because you're peeing jet black urine

I can't tolerate most dairy products, but that's Ok because I like soy. A cheese like Edam is fine so long as I only eat small amounts of it, but cows milk will seriously upset my stomach. Somebody suggested I try goats milk, but that gave me shocking flatulence for a day so I'm never going to try that again.
There's an Indian supermarket in the township and I buy most of what I eat from them, apart from fresh fruit and veges, because it's guaranteed to be vegetarian. I like Indian food, - genuine Indian food that is, - hot spices and all. In the big supermarket in town anything vegetarian with a western label on it is very expensive which is why I shop at the Indian supermarket where everything is much more sensibly priced. The owner of the Indian supermarket was concerned at first when I started shopping there because I was fearlessly buying things which were seriously expert level spicey, but they are used to me now and don't try to warn me off buying things most white New Zealanders would find just plain too darn hot for their taste.
I'm not particularly wheat tolerant either so I eat brown rice as well as chickpeas and foods that use chickpea flour instead.
I now weigh the same as I did when I was 19 and I feel so much better for being exclusively vegetarian with much better energy than I had before.
