For whom would calorie restriction be dangerous?

I don't get the time and monetary cost either. You can precook your meals for a whole week on Sunday night, as long as you don't mind a little repetition.

It might be quite hard to consume a sufficient amount of certain nutrients like Calcium on caloric restricted diet as well.
