The words I'm looking for would be used for a multiple choice list in a fill–out form for submitting dietary preferences for a dinner. I would like to refrain from pointing to allergies or dietary restrictions in the question as some people simply choose to eat a certain way rather than needing to eat that way for one reason or another.
"Carnivore" is often thrown around as an alternative for cases like these.
The issue with this term — in my eyes — is that it is both too exclusionary (as people who hear "Carnivore" think of something that eats exclusively meat) and not exclusionary enough (as it could be defined as "something that derives its nutrition from meat." Cambridge, American Heritage, and Princeton use similarly loose definitions. These definitions do not exclude alternative sources, instead merely state what is included.)
Is there a term for someone who excludes vegetables from their diet, but still partakes in meats, fruits, nuts, grains, tubers, et cetera? Are there terms for people who do the same with other items, for example exclude fruits, but partake in the rest?
The best solutions I have been able to come up with are compounds. I.e. Vegetable–exclusionary or Fruit–exclusionary but these terms aren't quite as clean and universally understood as, say, vegetarian and vegan. I understand that there may not be any universally understood term (as vegetarianism and veganism are culturally ubiquitous in the West, whereas that which I am looking for clearly isn't) but I figure there may be some well–defined terms which people could look up in the event they are confused about the alternatives.
