   You will lose a minimal amount of mass overnight. You won't do so because it is night—night has nothing to do with it—but because time is passing. You must burn calories to stay alive, and, even though you burn fewer while you are sleeping, you would still burn some just to keep your metabolism going. That's the basic loss of mass, and it is minimal: less than a pound.

    

   I suppose if it were really hot, you could sweat off more, but that's the basic reason: even your resting metabolism burns energy.
