I'm having trouble getting it to load, but it reminds me of something a christian fitness trainer did.  He started out lean, muscular, and hunky.  His whiny clients kept complaining that he didn't know what it was like to be fat, so he decided to gain weight and lose it just to shut them up.  He gained about 70 pounds of fat if I recall correctly.  It affected his whole life.  He felt disgusting.  He couldn't face his own wife.  Even after he lost the weight, he was still obviously somewhat emotionally scarred by the experience of being so fat. I always remember that whenever someone tells me they're perfectly fine with being fat.
