He really looks puffy and jiggly even at the end...  I don't know whether that's the swelling he was talking about right after, though.  His arms don't look very fat, but his torso is like a big bloated rectangle still.  It's hard to understand.  I think it must partly be the swelling. I'm curious to see how much of that alien appearance would remain if he really cut down his body fat to a very low percentage. I think that even his facial skin was a bit saggy...  he is certainly marked for life as a damaged creature, whether he backslides in the future or not.
