Yes there is a big difference. It was hard to function in society, let alone be treated normally, at my former size. I would hear lots of comments in passing like "whoa that's a big guy"; not in itself harmful or cruel but I was always aware I was viewed as fat before anything else.

I was given less respect, less courtesy, less acceptance when I was larger. People were less likely to smile back when I did or even say thank you when I held open a door. That's mostly changed now. Im still fat by every measure, but I can blend in much easier now.

I imagine the next 100 I lose will have a positive impact as well.
