I generally don't bother with voting if it requires registration but the fact that you provided pics in the OP motivated me to try. However, I still haven't received the email to finish registration. I was this close to saying screw it, but then you posted more pics...so I'm not giving up.
Two additional comments.
First, you have a pretty cool wife. Being a chemical engineer is no easy feat (btw, bachelors or advanced degree?) and allowing you to post these pics is sweet.
Second, echoing what someone else said, unless she lost a lot of weight I doubt she was "fat" to begin with.
Update:
I recreated the account and received the email. +1 vote for your wife. I also noticed one of the commenters was Casiotech.
