what's the adj of fasting ( man who don't eat for some reasons)

[Hekmat Mrad]

We learned that "interasted" is the adj from interest
so is it possible to add ed to "fast" in order to form adj Ex. I'm fasted ( not taken any food ) .

I can't think of any way of saying it as an adjective. As far as I know, it can only be used as a verb or a noun:

I'm fasting.
I was fasting.
I fasted for three days last year.

He is on a fast.
She is going to try a fast next week.

I'm honestly not sure if there's a specific verb that should be used with "fast" as a noun (by this I mean I don't know if one "goes on a fast", "does a fast" etc), as it's normally simply used as a verb on its own.

I'm sure you're right, emsr.

I wondered about a fasting blood-test, when you eat or drink nothing for 12 hours before the test. But it's not an adjective as it doesn't describe blood-test. It's one noun modifying another.

I can't find any dictionary listing an adjectival form of fast.

While we're on the subject of fasting, the meal in which you break your nightly fast is breakfast (with, as most forum members will know, a shortened /e/ sound in the first syllable.) In rather old-fashioned Br English it is possible to use 'breakfast' as a verb, with a regular simple past ending. So it's possible - if rare - to say 'he has breakfasted'.

Just to say, you can talk about 'fasting patients' when discussing hospital treatment of someone on a fast.

[BobK]

That's a good point. In a multi-cultural environment such as this forum it's easy to assume that fasting is a strictly religious practice. But hospital patients do fast when required, and hospital induction questionnaires often have a check-list that includes a question such as 'Do I need to fast before the appointment, and if so for how long?'

It would have been a good point had I not been thinking of patients fasting during Ramadan and the protocols hospitals have to follow when administering drugs during the hours of fasting.

I hadn't thought of that.

Adjectives can be formed from both the present and past participles.
"I am fasting" can be both a sentence in the present progressive tense, and a description using the adjective "fasting" - "I am fasting. I am a fasting person."

If you have fasted overnight for above-mentioned fasting blood test, not only have you fasted, you are fasted. You are a fasted person. In fact, they sometimes ask you, when you turn up for such a test, "Are you fasted?"

fasting, adj. in a state of refraining from food.
fasted, adj. In a state of not having eaten for a specified period.

That sounds awfully posh to me. I take it you're on private health insurance.
