A small point but who's in charge of the aircraft? When such situations have arisen in the past the solution is relatively straight forward. "I will eat now pax or crew, whatever is available, if no crew then bring pax menu's, report the lack of food through the CC reporting system" Now who in the office is going to tell a Captain that he cannot eat? End of story. I do not work for EK but my own airline has a passage in the Ops manual stressing the need for crew to hydrate and eat whilst flying, am sure EK have a similar?
