I often wonder how far ahead this show is taped? That might have something to do with the time lapse between when the contestant has left the show, and when they show the update. Last week the update was a little unusual with Jesse leaving, then Arthur leaving the following week. We already saw Jesse thinner, and then when all the contestants went home for two weeks, we saw Jesse heavier again.
I am only guessing here, but just how much do they screen the contestants? Are they perhaps screening the contestants differently? Of course, I am only into this program for a few seasons, but the contestants this season seem to be nicer than past ones. That probably sounds snobbish, but moral character is what I am talking about. Of course the show is so highly edited they only show us what they want us to see.
