Foods that have no calories

Boy, what a great way to lose weight. Anyway,
Some Lucky dill pickles have 0 calories.[says so right on the jar]
Coffee 0
salt & pepper 0
Soda 0 [they say one, but it really has none]
Celery: some [but the work of eating makes it none]
Mushrooms [Id say same as celery but can't verify it].

There, make yourself a tasty meal and lose weight at the same time. All you can eat.

Are their any other foods?
