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 ) .
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?"
