Well, not nearly everything that tasts good is unhealthy and things don't always become more tasty the more fattening ingredients you put in.

That being said, many thin-focussed people are afraid of anything that might even be remotely fattening. Not having that fear does remove a barrier and open up the options when it comes to ingredients. Nothing can replace a stick of real butter or a dash of heavy cream in my eyes. And diet-coke just doesn't taste right to me.

Long story short: Not every FA makes a good cook and not every good cook is an FA, but I definately think a fat hater is less likely to become a good cook then fat admirer.

In other news, sexual interests are proper gauges of someone's cooking ability or proficiency in other hobbies, some of which may be tangentially related to said sexual interest.
