I am a vegetarian, and have been for 25 years, but mnm464, your dietary needs will be unique because you are a teen and engaged in intense athletic training. I am neither of the above.
It is fairly easy for me to eat a balanced vegetarian diet and to get all the vitamins I need. (As a woman of a certain age, I have had all sorts of tests, just because they do that when you are over 50, and not one vitamin deficiency). Not only are tofu and beans and meat analogs a good source of protein, these days, they are everywhere and easy to get. I also exercise regularly (but not nearly at the level of training that you are) and have had no endurance issues. But I became a vegetarian for ethical reasons, not for health or for weight loss, so I am not restricting calorie intake. And as someone who grew up thinking cheesesteaks were one of the major food groups, it wasn't that easy...
I also have plenty of baby fat, even if it is a little too late to call it that.
