MEN! And it has been scientifically proven. According to Dietician Lisa Young, PhD in the book "The Portion Teller Plan" it is called "dietary convergence." This basically means when a woman moves in with a man she generally gains weight. The reasons:

More late night snacking

Matching him bite for bite

More food-centered love

So...have at it ladies. Start blaming your man. And men...just say "okay". :)
