Anorexitarian
An anorexic vegetarian for whom vegetarianism is just another way to obsess about their eating habits and to justify their denial of eating foods to themselves or in front of other people.
The true sign of an anorexitarian is instead of saying: "Two slices of pizza has more calories than I eat in a week" - the anorexitarian will say: "I cannot eat this black olive and spinach pizza because the pizzeria does not have a separate pizza oven for vegetarian or vegan pies. Pepperoni may have touched my pizza."
