Translation:No matter how much food there is, I will not eat.
When paired with όπου, ό,τι, όποιος, όσο etc it gets the meaning of every-.
Όπου και αν είσαι=Wherever you are/No matter where you are (depending on the following sentence)
Όποιος κι αν είσαι=Whoever you are/No matter who you are (-//-)
Όσο κι αν θες=No matter how much you want (there is no how much-ever :P )
