Breath

While it is certainly true that our breath becomes foul in a fast, brushing our teeth, gums, tongue and mouth (just with water) makes an amazing difference, much more so than i had originally realized. In a recent fast, i was talking to my brother from 8 feet away and he reported smelling the foulness from that distance. 5 minutes later after brushing, i tested my breath again by breathing directly into his face from 1 foot away and he said it smelled fine.
