Vegan friends won't accept newly turned vegan girlfriend

When I first made the healthy switch to a vegan lifestyle, most of my friends goofed on me for weeks. After about a month, they were saying I smelled funny. Is that even a thing? What could make me smell funny? Anyway, I started rubbing it in their face that I respected my body more than they did theirs, and they all stopped giving me crap and returning my calls.
