Hi. I suspect he knows that he doesn't need anything if his sugar dips because he's probably not on medication that would cause hypos. He just likes sugar as most of us do! How about suggesting some alternatives such as nuts, certain fruits etc as snacks. I'm sure it's not easy as his colleagues will no doubt be snacking on sugar-laden foods, but hopefully a sensible discussion with him will help. I hope he doesn't really believe he needs them. Ask him how he knows his sugar levels have dipped and where to.
