I don't want to get hopes up too high, but you'll notice that you apparently get to choose a body type at the first screen based on the screenshots shown, and then you get to choose from those four body types later in the appearance section. Since the origin tab isn't exactly a summary, there's at least a chance we actually get four physical builds - average, buff, skinny, fat would be my guess. We'll have to wait and see though.
As Darkwood mentioned, that could just be because bodies aren’t gender locked and there is only normal and buff variants. If there is more variety I’ll be elated though. The elves and half-elves are all too tall. As a mixed race person who has never been mistaken as tall, my favorite race is half-elf because I identify with them visually.
