Threw the chocolates in the trash, now in a sweet crisis

My spouse decided to go on a diet and completely cleaned out the kitchen. They threw away all the chocolate, biscuits, and snacks. But now they’re going through sweet cravings, constantly wandering around the house asking, ‘Is there anything?’ I don’t understand why someone would do this knowing they can’t hold out. How do you think I can help them, or should I just not get involved at all?
