Answer
Following a strict vegetarian or vegan diet comes with many challenges. Firstly, when you go out with friends and eat at a restaurant you have to make sure that that restaurant provides vegetarian or vegan alternatives. Secondly, finding ready-made vegan food is very hard so you'll probably have to make your own food which can sometimes be expensive. It is hard to get all the nutritional elements you need when you are on such a restricted diet, so you need to be well informed about the foods you can eat. A vegetarian or vegan diet is possible, it just needs a lot of time and effort put into it.
