I'm not a fan of a vegetarian diet because it leaves out the most nutrient dense foods.
I haven't done research into it specifically, but I would avoid carbs and sugar (and all processed foods), and eat a lot of avocado and protein from non-carby foods (beans and quinoa are ok, but still have a lot of carbohydrate).
