It is really hard to tell. More so because the more fat you have, the more water you most likely will have too. Unless you are taking a bunch of stuff with HEAVY water retention, if you look smooth or fat, you are smooth and fat. It's pretty hard to be lean but have it "hidden" with water without heavy drug use. For instance, when I run test C or anything that I find causes some water issues, I don't notice till I come off. After a few weeks off or so, a few areas harden up a bit that previously had a smooth layer over them. It's not dramatic though...it's not enough to change how my clothes fit or anything like that, it's mostly just a visual thing for me.
