Not only that, but fat is the opposite of love.  Want to show your partner how little you care about them?  Gain weight till the point where you're no longer physically attractive.  I cannot believe how many women (and to a lesser extent, men) do not understand that gaining weight is worse than cheating.  I would rather my wife be out fucking everyone in town than gain 80 pounds, because as long as she's also still fucking me, at least I have an attractive sexual partner.
