Are you a follower of the diet or philosophy known as vegan?
No, I do not think I could do that at all - I love steak!
Me neither! But vegan diets have benefits. They can reduce the risk of some types of chronic disease.
Yeah I know some people that eat that way for health reasons.  Are there any risks to eating that way?
If a vegan diet isn't properly planned, it can lead to deficiencies in several different vitamins. 
I would imagine it may be hard to try to maintain all the nutrients you would be missing.  Are there other reasons people eat this way?
There are many reasons why people become vegans. One of which is environmental reasons. Environmental vegans avoid animal products on the premise that harvesting or industrial farming of animals ins environmentally damaging. 
Ah that is pretty interesting - what about religious reasons - are any people vegan because of that?
I'm not sure about religious reasons, but there are ethical vegans who follow vegan diet and extend the philosophy to other areas of their lives, opposing the use of animals for any purpose.
