Is it me, or is the average body size of Sims in TS4 skinnier than one in TS3?

I think the difference is that the sliders are a little more extreme? In ts4 you can make a sim look like bones or fat or thick. There is a lot of control. You can change their muscle or fat content as well as use the sliders. I don't really feel there is an average or standard ts4 body. The basic starting body could possibly seem a bit thinner but only if you choose to leave it so ?
