Yup.  I am a chef.  What you describe is a foodie for sure.  It's someone with a real understanding a love of the art behind cooking and food, but isn't a professional.  It's like a person who collects fine art but is not themselves an artist.  You can still have a deep appreciation of the skill and creativity it takes to create a meal.  Fats only like things that are laden with grease, sugar and salt.  As a chef, nothing is more insulting than spending many hours planning, crafting, subtly seasoning and serving something truly inspired only to see some fat ass pour salt and pepper all over it before they even try it.  They have totally dead taste buds and would probably be just as happy at McDonalds eating cold fries.
