I don't see why it would be a problem, afterall, they probably look at it as more pounds in their pockets at the end of the day.
Good for your hubby wanting to do something about his weight too. It will be great for you to be able to spur each other on too.
I'm with the others though, there wouldn't be any room in my cupboard for anyone else to come into. Good luck and I hope he gets the answers he needs.
