Pollotarian, pescatarian, vegetarian, vegan...what am I?!

When I first started cooking my own food when I moved away to college, I was introduced to all the different kinds of diets in regards to meat and animal by-product consumption...pollotarian, pescatarian, vegetarian, and vegan. Most people haven't heard of pollotarian or pecatarian even though they might identify with those eating habits. I had a friend in college who called herself a pollotarian when I first met her, became vegetarian shortly after, and a couple years later went vegan. Because of the nature of the vegan diet, it was difficult for her to get the protein that she needed so she has since gone back to simply being a vegetarian.

So...not that I've used all these different words, let me define them for you.

A pollotarian is someone who eats poultry i.e. chicken, duck, turkey, etc. Some have used this term to mean someone who eats both poultry and fish but technically one would not consume any fish.
A pescatarian is someone who eats fish i.e. cod, salmon, swordfish, shrimp, etc.
A vegetarian is someone who doesn't eat any kind of meat but eats animal by-products i.e. eggs, dairy products, honey, etc. You can even break this category down more into two more categories:

1. ovo-vegetarian, someone who eats eggs
2. lacto-vegetarian, someone who eats dairy products

A vegan is someone who doesn't eat any kind of meat and won't eat any animal by-products.

I haven't done a whole lot of research on these different eating habits and lifestyle decisions other than what I learned in the general nutrition class I took in college and from the many friends I have who have either tried out one or more of these options or who are have been eating one of these diets long term. For short periods of time, I have only eaten fish and poultry but never for very long. For me, I hate to say it but rather than being about animal rights, my diet is much more about nutrition.

I have threatened to become a vegetarian many times in the last 10 months but every time, my boyfriend has talked me out of it and convinced me to simply have more moderation in my consumption of beef and pork. Personally, I think that all diets are about moderation...cutting something  you love out of your diet can make you want to binge on something else thats unhealthy. It's easier to eat healthy when you treat yourself a little bit as a reward for eating well.
