Being vegetarian is very healthy!! Just like when you eat meat, you need to make the right choices. Being vegan means you don't eat any dairy, either. I was vegan for 1.5 years before I decided to just go back to being vegetarian, since there are a lot of ingredients derived from milk that are in everything, and it's much harder to make sure you're getting proper nutrition.

I'd even venture to say that being vegetarian is healthier than not- you don't have tons of cholesterol or fat in your diet, and you most likely get more fiber- a type of diet that is very healthy! Good luck!!! It's great that so many PTer's are going veg!
