I'm new to prolog language recently started teaching my self this language I came across an interesting question which says to Write a database for a predicate cycle/1 such that query

cycle(X)

returns the instantiations
   X = food 
   X = me 
   X = pizza  
   X = food 
   X = me 
   X = pizza 

in an endless cycle

How do we do that can someone help me out am trying to touch my self this language!

hence: it's JUST FOR LEARNING PURPOSES!
