Only "empty" will work. "Empty" can mean a very negative emotional state. Did you mean "empty" to mean "hungry". If so, I would use "hungry" to avoid misunderstanding. You have misspelled "feel".

Please check. "Whenever I come back from gym I fell empty or emptied"?
If you're talking about needing food, then you need "hungry". If you mean that you have been emptied of all your energy, use "exhausted" or something similar.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
