ELI5 why are we typically less attracted to fat people?

Genuinely curious why people generally are less attracted to a fat body as opposed to a fit one. What sociological, anthropological and developmental angles can explain it?

In a really reduced nutshell:

At a base, genetic level, humans are concerned with the survival of the species. So, in turn, we are hardwired to find those qualities attractive that will aid in that endeavor (wide birthing hips, supple breasts, fit frame, etc). And those qualities unattractive that will hinder that endeavor (obesity, deformities, abnormalities, etc).
