I dont really see the problem either. I think that it is true of the old saying, 'where there's a will, there's a way'. If you want to make excuses, you will. And if you really want to do something you will figure out how to make it work for you within your limitations.
NO reason not to eat right, except for lack of planning. I know people on shift work or college students who eat while walking inbtween classes or even on bathroom breaks. Everyone gets breaks at work, even a bathroom break. So c'mon who's making excuses here?
As for working out, its about priorities. You work 12 hours, do you sleep 12 hours too? Probably not, so you have at least an hour to exercise then. Dont make excuses.
