Jillian left years ago (I don't remember exactly when but it's been a while). That's when I stopped watching. Jillian actually got results and got several of them back down to human status. The other trainers all seem to indulge the fats too much. I ended up catching bits and pieces of one of the latest season's recently due to my SO tuning into the show. I was doing housework but what I saw was pretty gross.  I don't know if it was because Jillian left or if it was because the show was starting to catch criticism about how they were pushing the fats too hard and they were "getting too skinny" or what but I don't think that one of them even got back down to human size. It was more like they went from morbidly grotesquely obese to still pretty fucking fat but not circus sideshow level fat anymore.  But... like I said... I really only caught bits and pieces of it in between cooking and doing housework while my husband was watching but it seemed like every time I walked in on it someone was crying and whining about something and complaining about one of the trainers being mean. Sheesh.
