Likely because most men suck at cooking, and most women are expected to cook. So it’s basically from “I’m eating to survive” into “I’m eating tasty stuff”.

When I was engaged there was some odd reversal of that, my then fiancée complaining about gaining weight. Because guess what, she went from eating what her anosmic mum prepared to what some wog prepared. And c’mon, food is a biiiig deal for us wogs.
