Any Cruiseship Crew members out there?

I currently work for a cruise line and I find it so difficult to keep on top of calorie counting when we are given food to eat as appose to making it for ourselves. It's even worse when you don't truly know the calories in what you are eating because you don't really have a guide put out in our Crew canteen.
Is there any Cruise ship crew members who have the same issue or have any advise on how to stick to it while still having to eat what you are given to work with.
