It depends on the person
I actually did a psychological study that explored this.
it separated the people into "strong, moderate and low" (i think) preference for thin people over fat people.
you may look at the link below.
I got that i had an moderate automatic preference for thin people when compared to curvy people.
you may look for yourself and see what you get.

The new word this year is curvy - to me, it means "fat". Fat is fat. Curvy is a nice word for FAT
I say skinny, fat, or obese
