I think it might have an impact on perceived reproductive fitness, though. A woman who can knock back the calories is going to be much better at carrying healthy fetuses to term.
Of course I do most of the cooking, so I tend to get miffed if my wife only pecks at her food. But we did go to a burger place on our first date. And I think her current favorite thing I make is either grass fed brisket or tri-tip roast.
